PurposeSystemic factors, such as diabetes mellitus, can influence the success rate of dental implants. The authors describe their experience using the MIS implant system (Medical Implant System, Shlomi, Israel) for retention of overdentures in patients with type 2 diabetes mellitus and provide data regarding the level of satisfaction of the patients, the improvement of function, mucosal and periimplant health, and bone level around implants in this group.MethodsThe study group consisted of 41 patients with type 2 diabetes mellitus who received 141 implants for retention of overdentures.ResultsThe success rate was 97.3% and 94.4% 1 and 5 years following implantation, respectively. The majority of patients reported improvement of function following the new treatment. A high correlation was observed between mucosal health and improvement of function. No correlation was found between failed implants and glucose level.ConclusionThe clinical outcome of dental implants in a selected group of patients with well-controlled type 2 diabetes mellitus is satisfying and encouraging. Further investigations and clinical trials over a longer period of time are needed to determine the long-term survival of implants in diverse groups of patients with diabetes mellitus.
