Ten years retrospective study of dental implant outcomes of 1241 dental implants using flapless techniques in two private dental practices in Brisbane, Australia

Introduction: Flapless technique has become a popular option in implantology recently. There are not many reports with large number of implants placed using this technique in the literature.

Objective: To assess retrospective dental implant outcome in a large series of cases using flapless technique.

Method: 1241 implants were evaluated in two private dental practices in Brisbane, Australia. Specific inclusion criteria included the use of flapless technique using a custom designed surgical guide and a 3 mm tissue punch. Success and survival rates as well as patients’ demographics, social habits and reason for implant failures were recorded.

Result: Majority (79.5%) of patients in this study were in the 40–69 year aged group. Cumulative 5 and 10 years implant survival rate was 98.5% and 97.4%, respectively, and the cumulative 5 and 10 years success rate was 96.0% and 94.6%, respectively. Most of the failed implants occurred in posterior maxilla (43.5%), in type IV bone (72.0%) and 44.0% failed implants were found in smokers.

Conclusion: This study showed that flapless technique achieved high cumulative 5 and 10 years implant survival and success rates, and that the most common factors related to implant failures were the quality of bone (type IV), and smoking.

Conflict of interest: This is part of the PhD project from Dr. N Doan, conducted at QUT, Brisbane, Australia.
