Dental implants in the diabetic patient: systemic and rehabilitative considerations

Diabetes mellitus is the most prevalent endocrine disease, comprising the third highest cause of disability and morbidity in the Western world. In the past, implant placement was contraindicated in diabetic patients because of increased risk for implant failure and infection. Publications in recent years have shown success rates for dental implants in diabetic patients resembling those of the general population. Other studies, in diabetic patients, as well as in animal models, have shown an increased risk for implant failure. These results raise the question of whether diabetic patients are suitable for dental implant rehabilitation. This article reviews the literature and presents the factors used in assessing the severity of diabetes and its complications, as well as the considerations for rehabilitation planning in these patients. Integration of these factors by the dentist dictates whether as well as what type of implant-supported restoration should be preformed.
