Metal allergy and failed implants

A recently published review articles looks at the connection between metal hypersensitivity and implant failure, with a particular focus on titanium. There is now a considerable body of evidence showing that titanium can induce hypersensitivity. This review gives a useful overview of several case histories where symptoms started after placement of a titanium implants and disappeared after the removal.

Highlights of review article on metal allergy

A new, remarkable, review of metal allergy should once and for all put an end to the belief that metal allergy causes nothing more than skin reactions. It lists hundreds of publications describing metal-specific allergy responses, identifying over 50 unique manifestations. According to the authors: “metals constitute one of the major classes of allergens responsible for a disproportionately large segment of the total burden of disease associated with allergy.”

FDA statement on amalgam

People with known heightened sensitivity (allergy) to mercury or other components of dental amalgam should not get amalgam fillings, according to FDA's new directives on amalgam fillings. Inhaling mercury vapour “may be harmful in certain patients” and “uncertainties remain on the effects that long-term exposure to dental amalgam may have on the specific high-risk groups”.

    “I have many patients that are interested in this type of testing associated with implants. Thank you for the great work you have done.”

    Dr Scott Schroeder, Podiatric Physician and Surgeon
    Foot & Ankle Center, Wenatchee, WA, USA

    “A type IV metal allergy is often overlooked as a culprit in many of today's chronic illnesses. MELISA testing gives targeted information on what needs to be avoided. Many patients get their life back with this information instead of remaining chronically ill for the rest of their days.”

    Dr Toril Jelter MD, General Practitioner & Pediatrician
    Mount Diablo Integrated Wellness Center, Walnut Creek, CA, USA

    “Working in holistic dentistry I use an integrated approach and treat the patient as a whole, focusing on the dental need in the larger context of the person’s overall well-being. MELISA provides me with invaluable information for the most suitable materials to be used.”

    Dr Goran D. Stojanovic, Dental Surgeon
    The Ella Clinic, London, UK

    “In daily practice, I see how dental metal fillings (eg amalgam), as well as dental or orthopedic implants, can have an adverse effects on arrhythmias (eg atrial fibrillation). For many patients, establishing a timeline between a dental or orthopaedic procedure and their symptoms developing will aid diagnosis."
