Background: Diabetes mellitus (DM) has several complications. Delayed wound healing, microvascular disease and an impaired response to infections are complications that can have a direct bearing on dental implant therapy. Material and method: A total of 56 patients were enrolled in this study who had received a dental implant as replacement of missing tooth in the mouth atleast 4 years prior to the commencement of the study. Of these 28 patients were diabetics whereas the other 28 were healthy subjects (control group).The demographic details of the patients were collected. Cases of implant failure were recorded and their correlation with both the groups was analysed. Results: Out of 56 patients enrolled in this study, 3 cases of implant failures were seen. An overall failure rate of implants irrespective of the diabetic or control group was found to be 5.35%. Out of 29 males 2 cases of implant failure were seen and only 1 failure case was seen amongst 27 females. Only 1 failure case of implant was seen amongst 19 patients who were below 35 years of age. 2 cases of implant failure were seen amongst 37 patients who were more than 35 years of age. This study found 2 cases of implant failure amongst the diabetic group with a failure percentage of 7.14 percent. The control group observed a failure percentage of 3.70% with one case of implant failure out of 28 patients. Conclusion: A definitive correlation between diabetes mellitus and implant failure could not be justified and successful dental implant osseointegration can be accomplished in subjects with diabetes with good metabolic control in a similar manner as in subjects without diabetes.
