The short video presentation below shows the process by which Dr. Noumbissi and his team place one-piece zirconia dental implants. Assessment of the area where the tooth needs to be replaced is made clinically during a consultation but also enhanced with advanced 3D dental imaging obtained with a dental (CBCT) scan. The implant placement procedure is planned performing virtual surgery using Anatomage’s InVivo implant planning software. Once the planning is completed, the data is uploaded to Anatomage’s laboratory, a computer generated surgical guide is printed and returned in the mail in as little as 48 hours. The surgical guide allows for precise and virtually error free implant placement but also negates the need for large flaps and excessive bone exposure. This minimally invasive protocol reduces surgery time, improves implant placement accuracy, greatly reduces post surgery discomfort and drastically reduces healing time.

Holistic dentistry talks a lot about the dangers of silver amalgam fillings which can contain alarming amounts of mercury. Although we may be making some progress in regards to raising awareness on this important issue, all too many Americans still have silver mercury amalgam fillings. Some estimates say that up to 85 percent of Americans today have at least one silver filling and each of those fillings contain approximately 50 percent mercury. Americans and Europeans actually have more mercury in their mouths than exists in all manmade products combined – estimated at more than 1,000 tons.
In the United States, outside of dental use, mercury exposure generally originates from pollution from coal plants which in turn pollute ground soil and waterways and infect fish populations. For an expanded perspective on mercury use on the global scale we invite you to view a YouTube video created by the Blacksmith Institute. The video series called Mercury: the Burning Issue shows how Indonesian miners use raw mercury to discharge small amounts of gold from rock. This practice of drawing gold out using mercury is quite literally hundreds of years old. Ancient Romans were known to force slaves and criminals to mine in exactly this same manner using mercury. The mercury method is fast and cheap, creating a cleaner gold product than panning. Today, with gold values at over $1,000 an ounce, the poor and the greedy find it difficult to gold mining in any other way.
Why Mercury Use is a Problem For You
Mercury mining is a concern for everyone, no matter where on the planet we live. Although today mercury is mined mostly in China where it is supplied strictly to local users, most of the mercury in use in third world countries is filtering onto the black market from Europe and the United States. Ironically, mercury recyclers are collecting the substance from discarded light bulbs and other mercury laden devices with the intent of proper usage — however, illegal brokers are largely unregulated by any government entity, and this mercury is easily conveyed to market. Many of the countries involved in this type of mining ban the import of industrial mercury, but they can import all the so called “dental mercury” they can get their hands on.
Mercury is so toxic to the human body that when it comes in contact with skin, miners are exposed to high levels of the substance and as a result are rapidly dying from the primitive working conditions. Some 15 million gold miners, including 4.5 million women and no less than 600,000 children, are poisoned by direct contact with toxic mercury. In addition, mercury pollution flows out from the gold mines directly into rivers, oceans and seas, contaminating seafood far and wide. In this way, mercury is accumulating in the food chain, so that families and bystanders are being poisoned as they eat meals and generally go about their lives.
A Simple Solution to a Difficult Problem
Mercury dealers argue against regulating the use of mercury, insisting that by restricting mercury trade black marketers will be forced to go into the mercury mining business. However, these video showcase a solution that has recently been introduced to the miners – a simple system called a retort that can recapture mercury used in the gold mining process. This retort has been relatively successful in reducing the amount of toxic mercury emissions. ‘Mercury: the Burning Issue’ documents Blacksmith Institute’s project in Indonesia aimed at reducing mercury poisoning from the gold mining process, thereby saving the lives of innumerable miners, locals and anyone who might be contaminated by mercury infected fish from virtually anywhere the world.

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.
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.
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.

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.
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.
Dr. Noumbissi to Speak on Zirconia Dental Implants at the Holistic Dental Association 36th Annual Conference: April 18-20 2013, Herndon Virginia USA
On April 18 and 19 2013, The holistic Dental Association (HDA) will be hosting its 36th annual conference in Herndon Virginia in the United States. Since its foundation in 1978, the HDA ‘s mission has been to promote an awareness of dental care as it relates to the entire person. The HDA also brings together dentists who have a common interest in treatment modalities that are not included in dental school curriculum. Furthermore in recent years more and more people have heighten their awareness in their own health and regard good health to be more than just the absence of disease. Dr. Noumbissi is a member of the Holistic Dental Association and limits his dental implantology practice to metal-free implant dentistry. Over the last thirty years the only and most popular method of teeth replacement has been titanium metal dental implants and research is increasingly proving that implantation of metals can lead to systemic health problems in areas of the body remote from the oral cavity. Dr. Noumbissi will be one of the podium speakers at this annual conference and will be presenting clinical evidence of the safety and health benefits of metal-free dental implants.The topic to be covered will be “Zirconia a Viable and Sometimes Necessary Alternative for Teeth Replacement”.

Over the past century, the levels of fluoride in foods purchased at the grocery store have steadily increased due to several factors including; the mass fluoridation of water supplies, the introduction of fluoride-based pesticides and the use of mechanical deboning processes in the meat industry.
One of the biggest problems is produce – both organic and non-organically grown — which is sprayed with pesticides. The newer pesticides contain alarmingly high levels fluoride making the typical North American’s daily consumption about 1.8 milligrams of fluoride — almost twice the amount of fluoride delivered from drinking one liter of fluoridated water. The consumption of non-organic foods is now thought to account for as much as one-third of the average person’s fluoride exposure.
Where did we go wrong?
Early in 2011, the U.S. Department of Health and Human Services (DHHS) recommended that water fluoridation programs should lower the levels added to water from 1 ppm fluoride 0.7 ppm. Although helpful, even this measure clearly does not go far enough to solve the problem, as many children continue to ingest levels of fluoride much higher than is recommended, or considered ‘safe’. When you consider all of the sources of fluoride contamination it isn’t surprising that we are seeing a dramatic increase in dental fluorosis (a tooth defect caused by excess fluoride intake) and a marked rise in cases reported over the past 60 years.
Where is all this fluoride coming from?
The fluoride-based pesticide called cryolite (a white or colorless mineral made up of fluoride, sodium and aluminum in crystal form) is essentially sodium aluminum fluoride, which is used for its ability to kill produce-loving insects. Cryolite also adheres to produce in a thick layer that effectively ‘seals’ the produce in pesticide and is extremely difficult to remove before consumption. Fresh produce that is temporarily stored in a warehouse environment is also treated with a gas fumigant, used to kill insects and rodents. This fumigant is recognized to leave extremely high levels of fluoride residue “in or on” stored foods.
The naturally occurring levels of fluoride in fruits, vegetables, meat, grain, eggs, milk and fresh water supplies are generally very low (less than 0.1 ppm) with the exception of seafood, tea and deep-well water which all have elevated fluoride levels without human interference. As a general rule, the fluoride level in food increases as a byproduct of the industrial food-making process. This is particularly true in the U.S. where mass water fluoridation programs are in use, since food processors use the public water supply to make their products. The basic rule is more processing equals the more fluoride. Juice that is not made from concentrate will thus have less fluoride than reconstituted juice.
Organic food is less contaminated than non-organic food and a person’s exposure will thus be reduced if they eat more organic fruits, vegetables, grains, and legumes. Cereals, mechanically deboned meats, and black or green tea are sources to avoid if possible. Mechanically deboned meat is problematic because “most meats that are pulverized into a pulp form (e.g., chicken fingers, chicken nuggets) are made using a mechanical deboning processes. This mechanical deboning process increases the quantity of fluoride-laden bone particles in the meat. As a result, research has found that mechanically deboned meat contains higher levels of fluoride” (The Fluoride Action Network, http://www.fluoridealert.org/content/chicken/), which is then transferred to the consumer’s dinner table. Black and green teas are naturally high in fluoride regardless of whether they are grown organically without pesticides due to how the plant readily absorbs fluoride thorough its root system.
What’s so bad about fluoride?
Recent studies have shown that hydrofluorosilicic acid levels in the body increases lead accumulation in bone, teeth and other calcium dependent tissues. This happens when the free fluoride ion acts as a transport of heavy metals, allowing them to enter into the soft tissues where they normally would not be able to go, including sensitive organs such as the brain.
In terms of acute toxicity (the amount that can cause immediate toxic consequences), fluoride is more toxic than lead but slightly less toxic than arsenic – which explains why fluoride has long been used in rodenticides and pesticides. It is also the reason accidents involving over-ingestion of fluoridated dental products including fluoridated gels, supplements and water can cause serious poisoning even leading up to death. There are reports of people who have in fact developed crippling skeletal fluorosis – a bone disease caused by excessive consumption of fluoride — from drinking high amounts of iced tea alone.
According to the Fluoride Action Network (FAN) excessive fluoride exposure is well known to cause a painful bone disease (skeletal fluorosis), as well as a discoloration of the teeth known as dental fluorosis. It has also been linked to a range of other chronic ailments including;
- bone fragility,
- glucose intolerance,
- gastrointestinal distress,
- thyroid disease,
- cardiovascular disease
- certain types of cancer
People who are at highest risk to fluoride include infants, individuals with kidney disease, individuals with nutrient deficiencies (particularly calcium and iodine), and individuals with medical conditions that cause excessive thirst.
Fluoride also has the ability to stimulate the harmful effects of other chemicals and heavy metals in the environment, potentially making them even more harmful than they would be otherwise. For example, when you combine chloramines with the hydrofluorosilicic acid, the combination becomes very effective at extracting lead from old plumbing systems, promoting the accumulation of lead in the water supply – water which is then consumed by animals and humans alike.
What’s the Best Way to Replace a Tooth?
While both dentures and implants will fill the gaps left by missing teeth, there are other important considerations to be aware of when making a choice for dental repairs:
The expense associated with implants
The higher cost of dental implants can be the biggest obstacle for many patients to overcome when it comes to replacing one or more missing teeth. Despite their aesthetic and greater functional superiority the initial price of dental implants can cause many people to lean towards more conventional and less expensive options like bridges or dentures.
Success in the short term
Second to cost, another attractive aspect to dental bridges or dentures is the quick turnaround time since they can be ready and fitted at about 2 weeks, while dental implants take longer to become fully integrated into the mouth and jaw before they reach their peak performance level
However, there are a few additional costs associated with dentures and bridges which can include:
- restoring decayed teeth surrounding bridges
- treating gum disease caused by improperly fitted dentures and difficult to reach pockets created by bridges
- maintaining, repairing and replacing partial or fully removable dentures
The real cost of short sightedness
The actual physical structure of a jaw without teeth will initially shrink quite rapidly most particularly during the first six months — and more slowly over time for the remainder of the patient’s life. Consequently, when a denture is made to fit a person’s jaw it will need to be remade and refitted as the jawbone shrinks.
The teeth in a denture appliance eventually wear down and become less effective at chewing food. Worn denture teeth naturally cause a person to bite and chew with more force, pushing the denture into the jawbone, causing the bone to shrink at an even faster rate. Jawbone deterioration and loss is the major problem with removable dentures, a problem that also works to increase the speed of a person’s aging process. Grinding of the teeth will decrease the life of a denture also.
When a dental bridge is used to replace missing teeth, the supporting or adjacent teeth have to be ground down in order to make room for the support post of the bridge. Once the adjacent teeth have been altered in this way they become susceptible to damage and tooth decay. It is quite difficult for patients to properly clean the areas around and under dental bridges, which causes an accumulation of dental plaque and an increased susceptibility of tooth decay and gum disease. As in the case of dentures, the jawbone in the area where teeth are missing will shrink, weaken and deteriorate over time, which can cause the surrounding teeth to become loose, change position and even fracture in some cases. This mobility of the teeth will then create a situation where the structural integrity of the bridge is at risk.
The best long term solution
The average long term success rate of dental implant surgery in a healthy patient with good bone structure is over 95 percent. This figure can change to between 85 and 90 percent in patients who require bone grafting to increase density and to ensure that the implant will anchor well. For smokers, the failure rate of dental implants is about two times higher compared to non-smokers. Experienced implant dentists have success rate records as high as 99 percent for patients with healthy jawbone and gums. One of the most appealing aspects of a dental implant is that it works just like a natural tooth, without requiring any special care and without causing any damage to adjacent teeth. The only requirement to ensure the long life of a dental implant is for the patient to continue to maintain good dental health and proper daily oral hygiene – exactly as they would for natural teeth.
Once a dental implant has been placed and has properly integrated into the bone (a process called osseointegration) that implant can be expected to last for a lifetime, whereas dental bridges require replacement every ten years on average (due to bridge failure or adjacent teeth failure). Dentures also need to be replaced or modified about every five to ten years due to improper fit and bone loss. Therefore, although the initial expense for dentures and bridges may be relatively low, over time that cost will rise as repairs and replacements are needed, and as oral treatments are required due to gum disease and repair or loss of surrounding teeth. General health will also be affected as ill-fitting dentures do not allow for proper and efficient chewing.
Dental implants provide a much better aesthetic and functional results compared to alternative dental restorations. They help to ensure that a patient will be able to maintain their usual eating habits, keep a natural appearance and speak and chew without the embarrassment often caused by removable dentures.
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
- 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
- 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:
- 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.
