COURSE OVERVIEW:

Once zirconia dental implants have been placed in bone they need to be protected from early micro and macro movements. Furthermore during the four to five months of implant integration both for esthetic and functional purposes, clinician and patient have a need for protective appliances. Such appliances will vary based on multiple factors such as occlusion, finances and area of implant placement to name a few. The second aspect of teeth replacement with one-piece zirconia implants is the choice of adequate materials for cementation and definitive prosthetics. With a combination of lectures and live restorative demonstrations this course will focus on the prosthetic aspects of zirconia implantology. This course is designed to provide the clinician with the ability to predictably and confidently protect one-piece zirconia dental implants immediately after implant placement and during bone integration. The lecture material will cover selection of ceramics for predictable restoration of zirconia implants, how to select appropriate materials for priming and bonding of zirconia to zirconia and other ceramics leading up to cementation as well as cement selection.

 This course will include in-depth coverage of:

• Zirconia as a dental implant material.
• Bonding mechanism of zirconia.
• Soft and hard tissue assessment prior to implantation.
• Learn about appropriate prosthetic treatment planning.
• Selection of temporization modality for one-piece zirconia implants.
• Immediate, delayed and protective temporization techniques.
• Selection of permanent restorative materials.
• Restorative methods and materials.
• Achieving superior aesthetic results.

COURSE OBJECTIVES:

This course will enable you to:

• Recognize indications for successful metal free teeth replacement.
• Site preparation and/or preservation for optimal prosthetic results.
• Learn how to select and the indications for different temporization techniques.
• Utilize CBCT and virtual implant planning software to increase case success.
• Appropriate selection of permanent restorative materials.

Background

Since Dr. Brånemark first introduced titanium dental implants, a variety of materials have been used successfully for about 40 years. Today implants are made either of commercially pure titanium (cpTi) or titanium alloys.  In addition to its biocompatibility, titanium was also initially believed to be inert, nontoxic and nonallergenic1,2. However, several drawbacks have been documented in the literature with the use of titanium and titanium alloys as implant materials in medicine and dentistry. High concentrations of titanium have been detected in tissue surrounding dental implants mostly as a result of wear or corrosion of the titanium implant surface.  In an animal study Weingart et al.3   showed that nine months after titanium implantation, titanium particles had spread and were found in adjacent lymph nodes. This indicates the possibility that phagocytes could transport titanium particles to the lymph nodes without any initial or immediate inflammatory response and potentially cause later immunologic reactions.

The Facts

An increasing number of people who suffer some form tooth loss are choosing to replace their teeth with dental implants. For the last thirty plus years the only and highly successful option for freestanding tooth replacement available in the United States and other countries has been titanium and titanium alloy dental implants. There are increasing reports both in dentistry and medicine of individuals developing sensitivity and allergies to titanium and/or titanium alloys. Even of more concern some of these implants are corroding once exposed to body fluids such as saliva and developing electrical activity when they are coupled with prosthetic components made of other metal alloys. Titanium implants as they corrode are known to release metal ions which create low level electrical currents through the body but also weakens the structural integrity of the implants. With recent advances in implantable biomaterials research and technology, bioceramics such as zirconia (zirconium dioxide) are now available and a new generation of modern implants is made of zirconia. Zirconium Silicate (ZrSO4) is mined and is treated and transformed into zirconium dioxide which is also called zirconia. Zirconia is the crystal form of the material zirconium which is a transitional metal. After mining and processing of zirconium silicate, zirconium is isolated and further processed under high temperature and pressure. Zirconium then undergoes an oxidation and crystallization process which allows it to transition into a structurally stable and inert crystal. This bioceramic crystal is called Yttrium Stabilized Tetragonal Zirconium Polycrystal (Y-TZP) also called zirconium dioxide. Therefore zirconium dioxide is not a metal and presents exceptional physical and biological properties. Zirconia can sustain an extreme load capacity, features a very long service life, and presents no conductivity or interference in the body’s meridian systems; it is the most hygienic, non-electricity conducting and stable material for dental implantology and orthopedics. Zirconia implants also present no danger of corrosion, something that is often a serious problem with metal based dental implants. Corrosion of a titanium dental implant occurs when it is coupled with the metal framework or abutment of the crown which more often than not is a less noble metal or alloy than that of the titanium implant. The implant and crown assembly bathes in saliva which is an electrolyte and a good conductor of electricity; this leads to all sorts of chemical and electrical imbalances in the body and to a phenomenon called “battery mouth”. Another advantage of zirconia is its low affinity for plaque (picture#1). Clinical observations and studies show that zirconia implants compared to or next to titanium implants accumulate much less plaque and allow for superior gingival health (picture #2).

Radioactivity and Zirconia Implants

There is a controversial and highly misunderstood aspect of zirconium dioxide in terms of its radiological output. Zirconium Silicate (ZrSO4) depending where it is mined can be contaminated with natural radioactive isotopes including radium (226Ra) and thorium (228Th). This was a major concern in the early 1990’s because the ores selected were contaminated. Today zirconium dioxide processing plants have the technology to remove these contaminants and are able to yield and use very pure powders. For example, the radiation emitted by a 3 mol% Y2O3-ZrO2powder was the same order of magnitude as alumina powder, both of which were several orders of magnitude less than that typically measured for water, vegetables and livestock. Zirconia hip ball replacements weigh approximately 100mg and have a natural radiological output of 1mSv per year. The average weight of a zirconia dental implant is 1g, translating into a natural radiological output of roughly 0.01mSv/year. Therefore the radiation risk of zirconia bioceramics is negligible and given that the World Nuclear Association states that the typical background radiation experienced by most people in North America is 3.4mSv, there is little concern for adverse biological effects on the implant recipient.

Conclusion

Zirconia dental implants are a sensible and clearly a healthier alternative to conventional and titanium implant bridges, partials or Overdentures. Furthermore zirconia by virtue of its translucency and all-white color makes it the most aesthetically pleasing option available today for tooth replacement (picture #3 & picture #4). This is a new era in implant dentistry and the science of oral implantology.

BACKGROUND:

The National Center for Complementary and Alternative Medicine at the National Institutes of Health (NIH), states that “Integrative Medicine combines mainstream medical therapies and complimentary and alternative medical therapies for which there is some high-quality scientific evidence of safety and effectiveness.” An alternative medicine that is used in conjunction with a conventional one is known as a “complementary” medicine. An example of such practice is when patients undergoing chemotherapy use natural ginger syrup to prevent nausea. In 2007 a comprehensive National Health Interview Survey was conducted on the use by American adults of complementary alternative medicine which is also known as CAM. The results showed that approximately 38 percent of adults surveyed use CAM.  In dentistry dental implants are  a “conventional” or a mainstream dental therapy and currently the vast majority of implant dentists  use conventional medical therapies such as  surgery, synthetic drugs and titanium implants to manage healing and achieve bone integration and effectively replace teeth.

There is an overuse of synthetic drugs to manage patients recovery after implant surgery and this has led to many surgeons and other practitioners to underestimate their patients ability to self heal. This can only happen if they are detoxed and their immune system properly restored and empowered. Today an increasing number of people are choosing healthier lifestyles, alternative medicine and are more and more reluctant to accept metals to be implanted in their bodies. They also increasingly resist the idea of synthetic drugs-only options to treat or prevent health problems. Dental and medical research show there is increasing evidence that medical and dental metal implants will corrode and trigger various types of health problems in some individuals including metal sensitivity, metal toxicity, delayed healing after implant surgery,  and even delayed implant failure many years after implantation.

COURSE OBJECTIVES:

Miles of Smiles Implant Dentistry is presenting this unique two-day course where multidimensional medicine and holistic dental implantology intersect. This program is designed to demonstrate the intimate correlation between multidimensional medicine and successful zirconia (ceramic) implant surgery. The first goal of this course is to enable the participants to understand and appreciate the critical interrelationship that exists between a clean body, a boosted immune system and optimal recovery from implant surgery. As such during consultation the doctor will be taught how to obtain relevant information from the patient and determine what type of pre and post surgical detoxification and immune boosting protocols to request from the multidimensional physician. Protocols as simple as timely IV administration of targeted vitamins and minerals make a significant difference in patient recovery allowing for optimal, fast healing and ultimate success of dental implants. The second objective of this program is also to present  top to bottom natural, drug free protocols and methods of metal-free tooth replacement with ceramic implants.

This course will enable participants to:

• Obtain proper medical history.
• Order the right pre and post surgery immune boosting and repair protocols.
• Understand the importance of detoxification prior to implant surgery.
• Understand the rationale behind the use of zirconia as a dental implant material.
• Recognize indications for successful placement and integration of zirconia dental implants.
• Proper and predictable selection of temporization techniques for one-piece zirconia implants.
• Appropriate selection of permanent restorative materials.
• Use of natural, effective, less-invasive interventions whenever possible.
• Appropriate use of conventional and alternative methods to facilitate the body’s innate healing response after implant surgery.

Why ceramic dental implants are better than conventional bridges?

When it comes to options for tooth replacement patients are increasingly opting for dental implants over the usual dental prostheses such as dentures or conventionally placed bridges. Since implants sit securely in the jaw and look like natural teeth, they offer superior durability and outstanding aesthetics when compared to conventional bridges. However there is an increasing resistance to metals among people and in implant dentistry there is a shift away from metal or metallic based crowns, partials and implants.

There are four major categories of restorations available for tooth replacement:

Bonded dental bridge

Bonded dental bridges use the teeth adjacent to the empty space to help support the missing tooth by using a very thin piece of metal or tooth-colored material to overlay and bond to the back of the adjacent teeth. A tooth replacement or “dummy tooth” is set between these two bonded pieces in order to fill in the empty space. Failure rate is about 25 percent after just five years of use. Furthermore the gap widens because the bone recedes as a result of no longer having a tooth in place. This ultimately results in the weakening of the adjacent teeth which can become loose and eventually fall out.

Cantilevered dental bridge

A cantilevered restoration uses the closest tooth next to the empty space to support the missing tooth using the either the back of the neighboring tooth or a full crown to help support the missing tooth. Success rate is higher than with a bonded bridge depending on how much pressure the actual replacement endures due to grinding and normal wear. This method of tooth replacement has fallen out of favor because the supporting tooth gets torqued and fatigued and more often than not eventualy fractures.

Conventional dental bridge

Getting fitted for a dental bridge requires shaving down and modifying of the teeth on either side the space where the tooth or teeth are missing. This is done in order to fit a conventional bridge. This is a process that significantly weakens the ground teeth and sets them up for fracture and root canals in the future. Unfortunately conventional dental bridges predictably fail at a range from 20 percent over 3 years to 3 percent over 23 years.                                                                                                      With dental implants the dentist does not need to affect the health or longevity of neighboring teeth at all. Once placed, implants are firmly set into the bone making them more natural than dentures or conventional bridges, with none of the shifting that dentures normally display.

Some problems with conventional bridges

• They are bonded to the adjacent tooth with a glue-like substance, bridges more often become loose and fall out
• They cracks and fissure form over time, due to normal wear and tear and become fragile and prone to breakage
• Improper fit can lead to either tooth decay or irritation to the surrounding soft tissue around them.

Dental implant

A ceramic dental implant is created from a high performance material (zirconium oxide) that is inserted into the bone to act like a natural tooth root. Zirconium oxide also called zirconia is a crystal phase of zirconium and due to its nonmetallic construction the ceramic dental implant does not interfere with the body’s immune or meridian systems and therefore significantly reduces the potential for rejection. Furthermore ceramic implants do not interact with electromagnetic fields such as those emanating  from cell phones, cell phone towers and microwaves. Once inserted into the jaw, the implant integrates directly into the bone to give firm support to the artificial replacement that it is built to hold and should last the lifetime of a patient. Routine maintenance of a dental implant is exactly the same as a person would follow for normal teeth.

Healthy Patients Prefer Ceramic Implants

Patients who prefer dental implants say that they are more comfortable and provide a more secure fit than fixed bridges or removable dentures. However all implants are not equal and ceramic implants unlike metal implants are made in one piece from the root to the top just like a natural tooth. Therefore ceramic implants do not have joints and do not retain plaque and harbor billions of bacteria like two-piece metal implants. For those who no longer have any natural teeth, ceramic implants can be placed to support and retain dentures and eliminate the embarrassment and discomfort they can cause in social situations when they slip and click. Loose and ill-fitting dentures hamper the everyday pleasure of eating comfortably.

Reasons to consider a ceramic dental implant:

• preserves healthy natural tooth and bone structure
• looks and feel like natural teeth
• enhances a sense of self-confidence when eating, talking and smiling
• no gooey denture adhesives to deal with
• no embarrassingly loose dentures
• improves quality of speech
• no electrical or electromagnetic activity in your mouth

Anyone who is missing one or more of their teeth may be a candidate for implants. If more than a few of the teeth are missing, implants in supporting a crown or bridge can replace those teeth and function as normal teeth without concern for loss of bone and decay. If all or most of the teeth are missing, then implants may be placed to fix in place a full-mouth non-removable set of teeth.

No such problems with ceramic implants

Ceramic dental implants are recommended to patients because:

• Chewing is easy with excellent biting pressure provided by implant
• When done properly and dilligently cared for, dental Implants are reliable and provide long-standing service, for decades with few, if any complications
• Comfortable fit and lifetime durability because they are well secured and integrated with the bone and gums
• They remain clean because they do not accumulate plaque and bacteria
• Metal-free bioceramic
• They do not generate nor conduct electricity

Considering the overall advantages patients can expect to benefit from as a result of choosing a dental implant, they are better able to enjoy a healthier and greener lifestyle without the restrictions many denture and bridge wearers face. The more secure foundation offered by a dental implant, the better biting pressure becomes, making it possible to enjoy the foods that a patient probably would not be able to eat using a dental prosthetic. As a result improved chewing ability leads to better nutrition and improved overall health.

Biocompatible Zirconium Oxide Ceramic Dental Implants

In the world of medicine, zirconium oxide is being used more consistently as the material of choice for bone related reconstruction, particularly hip prosthesis. This growing trend has led to substantial clinical reports which confirm the high biocompatibility and quality of zirconium oxide, making it an attractive component for use as dental implants. Not only does Zirconium Oxide overcome most of the pitfalls of other dental implant products (such as Titanium), but patients now have a choice of a material that is esthetic, strong, pure, corrosion-free, biocompatible and capable of being used for all dental implant and appliance applications.

Why biocompatibility is so important

The immune system will typically respond to non-compatible dental materials as if they were infections or ‘invaders’ by initiating a cascade of reactions geared toward eliminating that ‘invader’. A good analogy to this would be how your body reacts to a cold or flu by elevating levels of lymphocytes and activating the immune system, a reaction that eventually rids the body of the cold or flu. The difference is that with dental toxicity the source of the problem is permanently imbedded in the mouth, and therefore there is no way for the ‘infection’ to be eliminated by the immune system.

Using only quality biocompatible materials that are proven to have very low adverse allergic reactions and present no negative responses from the immune system is highly important for the health of our patients. It is also the reason that biological, natural and holistic dental practices strive to use only materials that are as neutral as possible. Zirconium is a very strong, inert material with very low allergic potential and therefore a higher biocompatibility than other materials used as dental implants.

What non-compatibility looks like

Considering that every person’s body and physiology is unique, some individuals will be more compatible than others with certain types of materials used in dental treatments and procedures. But ultimately, a biocompatible material will not cause:

• allergic reaction
• irritation
• inflammation
• foreign body response (rejection)
• cancer and other autoimmune disorders

An all-ceramic dental crown over an all-ceramic dental implant looks and functions very much like the missing tooth did. Ceramic implants provide metal-free tooth replacement solutions, eliminating concerns of allergies and biocompatibility issues thereby lessening concerns for damage to the immune system. Zirconium Oxide provides safe, holistic results that are comfortable, natural in appearance and biocompatible:

• Zirconia implant is the holistic dental implant for absolute metal-free dentistry
• The white color of Zirconium far surpasses the metallic appearance of Titanium
• Ceramic implants and crowns retain less plaque and calculus than Titanium and therefore promote healthier gums and mouth

Our objective is to make as many biocompatible options available to our patients as possible and it is important to us to achieve the highest level of biocompatibility, particularly in cases where patients have compromised immune systems. Whenever considering a dental restoration we strongly suggest that extensive biocompatibility and metal allergy testing be done beforehand to ensure the best results.

Cell Phones May Pose Increased Health Hazards to Patients with Metallic Dental Implants

All cell phones emit electromagnetic radiation called RF (radio frequency) and EMF (electromagnetic fields). Considering the close proximity of the cell phone to the head during use, there is clear potential for EMF emissions to be harmful to any of the 300 million healthy cell-phone users in the United States today. However, patients who have undergone metal implant surgery as well as those who may still have amalgam fillings and/or dental fixtures are potentially at a much higher risk of harm than someone who has no metallic structures in their mouth whatsoever.

The use of metallic implants and fillings in the mouth is known to have the ability to create a potentially dangerous situation called ‘galvanism’. The body’s normal electrical (bioenergetic) current fluctuates at about 450 millivolts. Galvanism occurs when saliva mixes with amalgam (or metal) fillings and/or implants resulting in a jump of the normal oral electric current up to 1,000 millivolts or higher. This jump in oral electric current is without factoring in the amplified EMF fields associated with cell phone use and other types of exposure to electromagnetic fields. This kind of highly charged electrical current can quite easily overpower the body’s normal electrical flows and potentially interfere with energy flow to the brain. It is also suspected of causing various irritations to the nervous system.

What kind of damage are we talking about?

Studies have shown that the radiation from cell phones to which the user is exposed may in fact be the culprit behind a wide range of health problems including headaches, pressure or tingling in the head, earaches, eye problems including distortion of vision, memory loss, fatigue, brain tumors, DNA alteration or damage and changes in the brains electrical activity. Some studies have shown rats to develop lymphoma from prolonged electromagnetic fields exposure. For patients who have metallic dental repairs, the risk is quantified significantly. Additional symptoms may include:

• Increased arthritis
• Skin problems
• Ear problems
• Risk to leukemia
• Childhood cancer
• Sleep problems
• Depression
• Difficulty in concentrating
• Mental conditions

For more than thirty years, research conducted at the Electric Power Research Institute (EPRI) has focused on whether EMF associated with electricity can cause biologic changes or negatively affect health. Hundreds of studies have also been reviewed in health risk evaluations by the World Health Organization and other national and international organizations concerned with public health.

While some red flags have been raised over the years, what is being debated now at the national and international level is just how much radiation should be considered ‘unsafe’, and if there are any potential long-term side effects of continued cell-phone radiation exposure. Nobody knows with certainty what long-term health consequences EMF-induced biological effects may lead to – or how co-mingling metal implants and dental repairs with EMF radiation might affect the human body. The issue remains quite controversial. However, due to the growing depth of evidence pointing to various problematic interactions, concern is justified. Regardless, research has clearly shown that electromagnetic emissions from cell phones can cause significant biological effects and we know for a fact that metallic dental implants and fillings can create an electrical resonance of their own. When you combine these two disparate elements together, you have a potential recipe for disaster – one that can pose serious challenges to the long term health and wellness of anyone who has been fitted with metallic dental materials.

How metal implants may exaggerate harmful effects posed by cell phone use

Having dissimilar metals in the teeth (e.g.-amalgam; or gold and mercury, or stainless steel and mercury and/or titanium) causes a measurable galvanic action, or electrical currents, this is what is called “battery mouth”. These types of currents cause the amalgam levels (more often than not containing mercury vapor) to rise in surrounding tissues. The average mercury levels in gum tissue near amalgam fillings is about 200 ppm, and are the result of mercury flowing directly into the mucous membrane by way of galvanic currents. Dental amalgams also release significant amounts of silver, tin and copper which have well known toxic effects of their own. Even more alarming is the fact that amalgam containing zinc produces even higher galvanic currents.

Electrical currents can harm the immune system

Among other things, the electric currents and ionic flow between various dental alloys has been shown to cause irritation in the trigeminal nerve which is the main cranial nerve system; blocking the flow of major acupuncture meridians. This blockage can lead to greater overall dysfunction throughout the body and it can significantly challenge the immune system, which in turn can lead to chronic and debilitating health issues. It doesn’t take a much of an increase in the flow of energy to create harmful effects in the human body. Scientific studies associated with oral galvanism have determined that currents of just over 5 microamps is usually enough to cause significant health problems such as headaches, migraines, dizziness, nausea, etc. Removing the amalgam filling, metal fixture or dental repair essentially eliminated the problem in patients participating in this study.

Some studies have also found persons with chronic environmental exposure to electromagnetic fields including microwaves or MRIs to have higher levels of mercury exposure and excretion. And, interestingly enough, post MRI saliva mercury levels for a sample of patients reported on average 31 percent higher after MRI than before.

What the research reveals about metallic implants and cell phone use

Researchers in one study involved two basic types of implants: metallic pins and rings in the surface layers of the human body – positioned near the mobile phone. The goal in this case was to discover ‘the worst case scenario’ with respect to energy absorption. Researchers noted that “Based on the simulations of this study, the local absorption of EM field in a limited volume may be significantly (even by a factor of 700) enhanced by a conductive implant in the surface layer of a human body. The mobile phone and the metallic implant are strongly coupled, especially when the implant is close to a mobile phone, its length is in resonance with the field, and it is aligned with the antenna. This coupling can be either conductive, magnetic or both (Troulis et al 2003).”

Immediate symptoms of heightened danger

A few recommendations for reducing exposure to harmful EMF radiation when using a cell phone might include making only short and essential calls, and always use hands-free wired kits. Some studies suggest that positioning the phone’s antenna far away from the body during the calls may also be helpful. But, how can you tell if your cell phone is causing a problem? Several topical symptoms are immediately recognizable and they include:

• Fatigue
• Headache
• Warmth behind the ear
• Warmth on the ear
• Burning skin

The long term solution

Removing any amalgam fillings, metal fixtures or dental repairs will more than likely eliminate potential and confirmed health problems in patients. Overall, ceramic dental implants and repairs are the best alternative and they are highly resistant to corrosion and superior to other implant materials such as titanium and amalgams. They also have a higher level of human biocompatibility with the added benefit of a far superior aesthetic value for patients.

Are Metal Free Dental Implants Better than Titanium Implants?

Owing to their biocompatibility, high density and ability to withstand abuse, zirconia bioceramics are a far superior product when compared to metal for implantation in the human body. They are also an excellent choice as a dental implant material.

All-ceramic dental crown placed over an all-ceramic dental implant look and function very much like the natural tooth and they provide a top-to-bottom metal-free teeth replacement solution. This eliminates concerns of allergies and biocompatibility issues thereby lessening potential for damage to the immune system and adverse health problems. The term ‘bioceramics’ applies to a wide range of materials that, when compared to traditionally used metal implants, are harder and have higher temperature resistance, strength, very high density and excellent resistance to corrosion. These properties make ceramics invaluable for use in the oral environment where high temperature, corrosion and constant abrasion is ever present.

The Benefits of Zirconia Over Metal

While most dental implants are made of titanium, materials such as aluminum and vanadium are often alloyed or blended with the titanium which can create issues of allergy, galvanism and potentially impair the immune system in a number of ways. When differing metals are placed in the mouth or directly into the jaw bone as with a dental implant, those metals will eventually begin to release by-products from the oxidization process and are then circulated throughout the body.

For over five years zirconia dental implants have been available in the United States as an alternative to metal implants and they have been used quite successfully in Europe for over fifteen years. The advantage of these implants is that they are ceramic, and thus there is no concern of corrosion, galvanic/electrical activity or response to electromagnetic radiation. Zirconia (Zirconium Oxide) is not to be confused with Zirconium which is a metal found just below titanium on the periodic table. Zirconium oxide is the product now being used for the production of dental implants, it is the ceramic phase of Zirconium and it is called Zirconia.

Overall qualities of Zirconia dental implants include:

Biocompatibility: zirconium is an inert material with very low allergic potential.

Strength: The strength of the dental implant is exceptional compared to metal implants.

Metal-free: no corrosion, no galvanism effect, no metallic taste and no electronic disturbances.

Bone to Implant Contact:  Very high bone contact to the implant, above 75 percent.

Considerations Prior to an Implant

When patients exhibit overall healthfulness and are generally of a robust constitution, they tend to tolerate implants very well, but before considering something as serious as an implant procedure, a full health assessment is in order. In conjunction with assessing the patient’s physical state and ability to heal from surgery, most holistic dental practices are also concerned about the acupuncture meridian upon which the implant is placed. Every tooth in the mouth is located on an acupuncture meridian, and therefore can potentially affect specific organs, muscles, vertebrae and tissues.  Zirconia implants are preferable over metal implants for their biocompatibility factors but also very importantly they do not interfere with energy flow along one’s acupuncture meridians. Electrical skin resistance tests  are used to assess an individual’s energy system by measuring the energy meridian flows at specific accupoints on the body. These tests have shown that zirconia implants unlike metal implants do not interfere with the energy meridian system. 

Another consideration in whether or not to place implants for a particular patient has to do with whether or not they grind their teeth which might cause damage to the zirconia over time. In such cases nightguard is integrated in the overall treatment plan. Habits such as smoking or chewing tobacco may also negatively affect the long-term success of implants both ceramic and metal. And ultimately, patients with implants must be diligent about maintaining good oral hygiene.

How it Works

A reproduction of a tooth’s root is inserted in the jaw and over time, the implanted “root” bonds with the bone of the jaw. In other words, ceramic dental implants readily allow the bone to grow right up to the implant surface and is held securely in place by the bone. This process typically takes four to six months to completely heal before the permanent crown can be made.

Implants are integrated into the mouth in two basic stages.

First, a dental implant root is placed in the mouth. This root is often shaped like a screw. After surgery, the root will slowly integrate with the jaw bone in a stage called osseointegration which can take four to six months before the restoration(crown) phase of the process. Zirconia Implants have a very high bone-to-implant contact and some studies have shown up to 80% bone attachment to the surface of zirconia dental implants.

Once the osseointegration is complete, the dentist will take an impression to make a mold of your implant and other teeth. The mold will be sent to the dental laboratory and a crown is made just like on a natural tooth. The process is complete when the crown is returned and cemented on the implant. Since this crown is also made of zirconia it is usually indistinguishable from the surrounding natural teeth.

Caring for Your Implant after Surgery And Beyond

During the entire process, it is important for the patient to follow to all of the dentist’s instructions regarding oral hygiene. Regular brushing and flossing are key to the success of the osseointegration, and sloppy oral habits can potentially compromise a dental implantation surgery and the ultimate success of the implant.

Once your implant is fully integrated, caring for your teeth is very much like taking care of your natural teeth. Correct oral care must be followed including brushing and flossing at least twice a day. Ceramic dental implants will give you many years of use if cared for properly.

The Question of Radiation in Dental Ceramics

It may be surprising that one of the ‘risks’ associated with Zirconium based implants is radioactivity. But what does the research say, and is there really any risk to patients? The truth is that Zirconium just like aluminium and many other commonly used materials can contain a certain number of radioactive isotopes, which in extreme cases can increase the chance of oral cancers. However, oral implants are produced from a highly purified and stabilized form of Zirconium also called zirconia or zirconium dioxide which contains extremely low radiation emission levels. Furthermore all manufacturers of zirconia dental implants are required to provide a declaration of radioactivity for their zirconium based dental products. Therefore all zirconia products and materials are not created equal, because the quality and safety of each lies in the the processing of the raw material zirconium.

The Radioactivity of Commercially Available Zirconia Powders

Zirconium compounds are refined from naturally occurring ores, notably zircon, which usually contain trace amounts of other elements depending upon the source of the original ore. In particular, zirconia typically contains trace amounts of radionuclides. As a consequence there were some concerns about the use of zirconia ceramics as implant materials.

In 1992 the question of radioactive ceramics was officially addressed by Anusavice KJ in an article titled ‘Degradability of dental ceramics’ which observed in part that … “The degradation of dental ceramics generally occurs because of mechanical forces or chemical attack. The possible physiological side-effects of ceramics are their tendency to abrade opposing dental structures, the emission of radiation from radioactive components…”

However alarming that may sound further research indicated that the radiation emitted by a dental ceramic powder (3 mol% Y2O3-ZrO2) was the same order of magnitude as alumina powder, both of which were several orders of magnitude less than that typically measured for water, milk, vegetables and meat (based on European standards). The radioactivity of zirconia femoral heads (Y-TZP artificial hip joints) for example, has been shown to be similar to that of alumina and cobalt-chrome. The radiation dose of each material was recorded at that time to be well below European radiation limits specified for general external exposure of the human body and also for local internal exposure of organs and tissue, and was well recognized as no more than the ambient radiation of environmental surroundings.

In another similar study, radiation levels of several commercially available zirconia powders commonly used to manufacture implants in Australia (Nilcra Ceramics, Melbourne) were declared to be minimal and well below acceptable limits. The Radiation Health Committee of the National Health and Medical Research Council of Australia now consider that magnesia partially stabilized zirconia artificial hip joints made from these powders pose “very little hazard to surrounding tissue”.

The main raw material for the manufacture of zirconium dioxide (zirconia) in the US is the mineral zircon silicate (ZrSiO4) which is translated to a higher form of purity zirconium dioxide (ZrO2) when melted with coke and lime. Since extremely pure initial products must be used for the production of high-performance ceramics used in dental implants, special synthesis methods have been developed specifically for this product; a process that works to create the strongest, most durable dental ceramic product available today.

Radiation Absorption

Research has shown that in a dense ceramic almost all radiation is absorbed within the bulk of the material. In the case of artificial hip joints, any radiation from the femoral head is absorbed primarily by the surrounding artificial materials.

From these tests and others, it is widely recognized in the medical implant field that the actual radiation risk of zirconia ceramics is negligible, certainly no more than that of alumina – and consistent with the level of radiation found to occur naturally in healthy environments.

The Benefits of Zirconium Implants and Dental Ceramics

Overall, Zirconia (zirconium oxide) implants are valued by dentists and patients alike for being highly resistant to corrosion and superior to other available implant options such as titanium, both as related to biocompatibility and resultant color. They are ideal for those patients whose immune systems do not accept titanium implants and for patients who may have allergic reactions to metals. Zirconia implants are far more durable with less risk of breakage and is capable of holding up to the drastic changes in temperature and chemistry found in the oral environment. Being bright white in color, zirconia implants have a definite advantage or aesthetic value over titanium dental implants by eliminating the possibility of corrosion and the unsightly grey appearance that titanium exhibits.

What are the Benefits of Ceramic Dental Implants?

Well over 100 million Americans suffer some form tooth loss, and today ceramic dental implants represent the most aesthetically pleasing option available for tooth replacement. Ceramic implants are comfortable for our patients, and due to their all-white color they present the most natural looking results. Dental implants are the better alternative to bridges, partials or dentures (find out why ceramic implants are better than bridges here) and most importantly; ceramic dental implants perform just like natural teeth.

When teeth are removed or lost due to trauma or infection the underlying bone is no longer used, resulting in a weakened jaw and bone loss. This makes it difficult to smile, chew and do other things most of us take for granted. Furthermore teeth next to the lost tooth/teeth shift and and the opposing one(s)  drift into the spaces left by missing teeth. These ultimately lead to malocclusion, jaw collapse, jaw muscle pain and even chronic headaches. Dental implants provide the same function as the natural tooth root which they replace, including stimulating the bone in the most natural way possible and maintaining adjacent and opposing teeth in their place. Ceramic dental implants prevent bone deterioration and improve a patient’s ability to chew food normally.

Dental implants can last a lifetime and are placed directly into the bone where the teeth are missing. They do not adversely affect the adjacent healthy teeth as do traditional bridges. Implants bond to the jawbone and become part of it – making a connection as strong as a natural tooth root.

Some of the benefits of ceramic dental implants:

• Improve one’s ability to bite and chew
• Function exactly like natural teeth
• Do not interfere with adjacent teeth
• Provide a more youthful appearance to the face and jaw line
• Eliminate bone deterioration that can occur with tooth loss
• Do not cause unsightly metal coloring around the gums
• Are metal free and do not corrode or breakdown in the oral environment
• Easy to keep clean because they do not attract nor accumulate bacteria-loving plaque
• Do not conduct electricity or interfere with the body’s meridian energy pathways
• Provides stability without the need for messy adhesives

Whether you’re concerned about metals in the mouth or prefer to have natural looking teeth, ceramic dental implants provide the best alternative to titanium dental implants.

Metal-Free Dental Implants vs. Dental Bridges

The science of ceramic, metal-free dental implants provides a comfortable and natural alternative to bridges for patients who have suffered tooth loss. Metal-free dental implants are made of the ceramic component of zirconium also called zirconium oxide or zirconia. Due to zirconia’s physical and optical properties, metal-free implants are all-white in color , highly attractive in appearance,  and look and feel like natural teeth so much so that you might forget that you ever lost a tooth (for more information about the cosmetics of metal-free dental implants, please read The Cosmetics of Ceramic Dental Implants).

What’s the Difference Between Dental Implants and Bridges?

A conventional dental bridge can be made with a metal framework or entirely from porcelain or zirconia. However whether its metal based or ceramic, it is created by using adjacent teeth to support a pontic, or fake tooth. In this way, otherwise healthy teeth are often ground down and crowned (or “capped”) to facilitate a bridge to span the space where teeth are missing. So what is the difference between a bridge and a dental implant? A dental implant is applied directly into the jawbone mimicking the tooth’s natural structure without touching the surrounding teeth. An even better method of tooth replacement is by using zirconia implants therefore taking advantage of its metal-free and extremely stable physical properties. Zirconia dental implants do not corrode or breakdown when in contact with oral fluids, furthermore little to no plaque (tartar) accumulate on their surface.

How Long do Dental Implants and Bridges Last?

FAQ About Dental Bridges:

Most dental bridges last from 5-10 years before needing to be replaced. A bridge relies on the adjacent teeth and on the bridge’s structure for support. Surrounding teeth lose their strength due to being ground down to support a bridge and are susceptible to decay and even fracture due to loss of enamel and tooth structure in the process.

FAQ About Metal-Free Dental Implants:

Metal-free dental implants can last a lifetime and are placed directly into the bone where the teeth are missing. They do not adversely affect the adjacent healthy teeth, do not corrode or conduct low level electrical currents in the oral cavity. These low level electrical currents also called galvanic currents will lead to events ranging from weakening of conventional metal implants to the death of bone cells around implants;  this eventually leads to implant loosening and failure. Zirconia implants bond to the jaw bone and become part of it without affecting it – making a connection often stronger than a natural tooth root.

Do Bridges and Metal-Free Implants Cause Bone Loss?

Dental implants act as substitute tooth roots, providing the same function as natural tooth roots including stimulating the bone in the most natural way possible.  When teeth are removed or lost due to trauma or infection the underlying bone is no longer used, frequently resulting in a weakened jaw and bone loss. This makes it difficult to smile, chew and do other things most of us take for granted.

FAQ About Dental Bridges:

When teeth are lost or extracted, the bone that previously supported those teeth no longer serves a purpose and begins to deteriorate, or ‘resorb’. When a bridge is used to connect two teeth, normal pressure is not applied on the jawbone in such a way that the bone is stimulated as it would be in a healthy mouth, leading to bone loss in the area where the tooth was lost. Eventually the bone loss spreads to the supporting teeth of the bridge which over time gets loose, fractures and/or fails.

FAQ About Metal-Free Dental Implants:

Just like metal (titanium) implants, replacing teeth with metal-free dental implants involve placing an artificial root made of zirconia back into areas where there are no teeth. This results in renewed stimulation of the bone in the jaw preventing long term bone loss, thereby preserving and strengthening the structure of the jaw.

Not only do dental implants sit securely in the jaw and look like natural teeth, they also offer superior durability and outstanding aesthetics. Implants of a variety of materials have been used successfully for about 40 years and the latest generation of ceramic implant systems made of zirconium oxide (zirconia) take the science of dental implants to the next level.

Are Dental Bridges or Ceramic Implants Easier to Clean?

Caring for dental implants is very much like caring for natural teeth by following standard oral health care measure such as brushing and flossing.

FAQ About Dental Bridges:

Flossing bridges is not an easy task and requires time, patience and consistency making it difficult to follow routine everyday oral hygiene which can leave the underlying natural tooth structure at risk of decay and gum disease. Almost invariably over time decay occurs under supporting crowns of the bridge leading to the need for root canal treatment or tooth loss altogether.

FAQ About Metal-Free Dental Implants:

Individual dental implants allow easier access between teeth making it possible for patients to resume normal dental care. Furthermore zirconia dental do not collect plaque around them allowing for healthier gums and underlying bone.

Should You Choose a Metal-Free Dental Implant or a Bridge?

The bottom line for most people who have experienced tooth loss is that dental implants are a better solution. Implants are the closest thing possible to natural teeth, are fixed in place and offer a healthy alternative for oral and bone health, plus they support general well-being. Patients, who have metal-free dental implants a less likely todevelop metal sensitivity over time, remark that they look better, feel better and are more confident.
