In dentistry, allergic reactions to Titanium implants have not been studied, nor considered by professionals. Placing permanent metal dental implants in allergic patients can provoke Type IV or I hypersensitivity reactions. Several symptoms have been described, from skin rashes, lichenoid reactions, burning mouth syndromes, cheilitis and lip swelling, oral granulomatous reactions, gingival hyperplasia, gingivitis or even periodontitis and implant failure, to non-specific immune suppression. Degradation products of metallic biomaterials including titanium may result in metal hypersensitivity reaction. Although titanium hypersensitivity is a growing concern, epidemiological data on incidence of titanium-related allergic reactions are still lacking. The incidence appears to be quite low, but increases with increased quantity and duration of exposure to a causative antigen. In this paper, hypersensitivity reactions to titanium implants are reviewed with citing various metal allergy tests. [ABSTRACT FROM AUTHOR] |
