Abstract
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. Twenty patients participated in this study aged between 20 and 40years 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 1year. Final results showed that the success rate of closing OAF was 95% while the success rate of upper third molar auto-transplantation was 90%. This technique is simple, applicable, provides immediate replacement of the missing tooth, and does not require complicated instruments or procedures.
