Evaluation of a New Surgical Technique for Closing Oroantral Fistula Using Auto-transplanted Upper Third Molar: A 1-Year Follow-Up Study

Abstract

Background

Oroantral fistula (OAF) is considered a frequent complication in dental practice. Many surgical techniques/methods have been proposed to close it. The aim of this study was to evaluate the auto-transplantation of upper third molar for closing OAF.

Materials and Methods

Twenty patients participated in this study aged between 20 and 40 years old. The OAF was closed by auto-transplantation of upper third molar placed directly in the socket of the extracted tooth. Results were evaluated clinically and radiographically through the period of observation which lasted for 1 year.

Results

Final results showed that the success rate of closing OAF was 95% while the success rate of upper third molar auto-transplantation was 90%.

Conclusion

This technique is simple, applicable, provides immediate replacement of the missing tooth, and does not require complicated instruments or procedures.
