摘要

由於美觀之考量，上顎前牙因嚴重牙周破壞拔除後，由於齒槽骨缺損，後績之補綴治療上將會面臨許多挑戰！若是患者口腔內正好擁有一顆不具使用價值而且牙周完整的小臼齒可供我們進行移植，則有機會利用改良之二階段自體牙移植術式，提高牙周韌帶的存活率並增加周圍骨質再生的比率，如此即可有效地解決齒槽骨因為牙周破壞而缺損的問題。本文乃在報告一個上顎門牙因嚴重牙周破壞拔除後，接受改良之二階段自體牙移植術式，成功地將下顎小臼齒移植並替代上顎門齒的案例。

Due to esthetic demands in cases where severe periodontal destruction of an upper anterior tooth requires its extraction, the consequent prosthodontic treatment will be a challenge. In this circumstance, if the patient has a non-functioning tooth with an intact periodontal structure, there is the chance to transplant the tooth into the extraction socket by a modified 2-stage operative technique. In this way, the survival rate of the periodontal tissue and the regeneration ratio of the circumferential alveolar bone might be increased, and the problem of alveolar bone resorption due to severe periodontal destruction will consequently be resolved. This is a case report of a successful outcome of autotransplantation of a lower premolar by a modified 2-stage operative technique to an upper central incisor extraction site with extensive periodontal destruction.
