Effect of parafunctional force on dental implant treatment in bruxism: A case report (two year results)

An implant fracture may be one of the major causes of implant failures. the probable cause of the implant fracture was due to biomechanical overload caused by bruxism. bruxism (teeth grinding and clenching) is generally considered a contraindication for dental implants. so far,in the dental literature,the possible cause-and-effect relationship between bruxism and implant failure do not yield consistent and specific outcomes. this is partly because of the large variation in the literature in terms of both the technical aspects and the biological aspects of the study material. although there is still no proof for the suggestion that bruxism causes an overload of dental implants and of their suprastructures,a careful approach is recommended. this case report illustrates the importance of an extensive clinical examination and accurately occlusal arrangements of oral implant patients for the presence of severe bruxism for two year results.
