摘要

本篇病例因病人上頜竇較低，上顎第一大臼齒拔除後右側有口竇相通的情況；左側則是受植區的高度不足以容納移植齒牙根長度，兩側都是自體齒移植的相對禁忌症。然而，右側利用移植齒本身作為修補口竇相通的術式，左側則採用上顎竇提升術於自體齒移植的術式，兩側在術後均復原良好。本病例運用不同術式解決了上顎竇的限制，且擴大了自體齒移植應用於上顎後牙區的適應症。

Autotransplantation of tooth (ATT) is a reliable method with a good prognosis to substitute a hopeless tooth. The structure of maxillary sinus creates an anatomical limitation for ideal tooth transplantation. The complications from oro-antral communication (OAC) often occur after the extraction of the maxillary tooth. We represent a case who was received the autotransplantation of teeth combined with sinus repair and sinus lift and had a satisfactory result.The patient was a 25 year-old male and had severely decayed bilateral maxillary first molar. Because the patient had bilateral third molars at both side of the mouth, we planed the autotransplantation of teeth to restore extracted areas. An OAC ,about 6 mm in size, was noted at the apical area and the donor third molar was transferred to the recipient socket to repair the communication on right side. And on the left side, ATT combined with the operation of osteotome sinus lift was applied to overcome the compromised maxillary ridge.Two years after the operation, the transplanted tooth was healthy in periodontium with stable occlusion. Autogenous tooth ransplantation used for sinus repair or combined with sinus lift technique expand the indication of tooth transplantation, and restores the masticatory function fast and economically. It is an alternative option to restore the missing tooth at maxillary posterior area.
