Background: This study was conducted to assess the prognosis of dental implants in subjects having diabetes mellitus. Material and methods: 100 participants in all participated in the study. The individuals were split into two groups: the first group included 50 healthy subjects and the second group included 50 diabetes subjects. Patients with partially missing maxillary and/or mandibular arches who later underwent oral rehabilitation with dental implants had their medical histories, dental x-rays, and clinical records retrieved. Based on the assessment of their glycated hemoglobin (HbA1c) measurement at the time of implant implantation, this differentiation was made. According to the American Diabetic Association (ADA), those with HbA1c levels below 6.5% are classified as non-diabetic (healthy), whereas those with levels above 6.5% are classified as diabetic
