Evaluate the survival rates in diabetic patients receiving immediate function implants

Abstract

Background: Diabetes mellitus, a common endocrine disorder, has long been associated with increased risks of dental implant failure and excessive marginal bone loss due to impaired healing and microvascular complications. While previous studies have suggested that glycemic control is crucial for successful dental implant outcomes in diabetic patients, the exact survival rates and factors influencing marginal bone loss remain inconclusive. This study aimed to evaluate the survival rates and risk indicators for excessive marginal bone loss in diabetic patients receiving immediate function implants.
Methods: This cohort study included 70 diabetic patients (6 with type 1 and 64 with type 2 diabetes) who underwent implant-supported restorations . Implants were placed using an immediate function protocol, with clinical follow-up . Data on implant survival and complications were gathered, with radiographs taken Primary outcomes included cumulative implant survival, while secondary outcomes focused on marginal bone loss and biological complications. Statistical analysis included Kaplan-Meier survival estimates and multivariate logistic regression.
Results: A total of 352 implants were placed in 70 patients, with a 5-year follow-up. The overall implant survival rate was 89.8%, with type 1 diabetics showing a survival rate of 80% and type 2 diabetics 90.5%. Biological complications, including peri-implant pathology and fistula formation, were observed in a small proportion of patients.
Conclusion: Dental implants in diabetic patients, particularly those with well-controlled blood sugar levels, demonstrate a high survival rate (89.8%) .Proper glycemic control, infection prevention, and addressing modifiable risk factors are essential for improving long-term implant outcomes in diabetic patients.
