上顎前牙橋體區域的牙根掩埋術應用:病例報告

Root Submergence Technique for Pontic Site Development in Maxillary Anterior Region: A Case Report

摘要


牙齒拔除後會導致齒槽脊吸收,如位於上顎前牙區將導致嚴重的美觀問題。牙根掩埋術(Root Submergence Technique, RST)是將牙冠去除至與齒槽脊一樣或更低的位置,以保存牙根及周圍的附連組織,進而避免齒槽骨吸收及維持外在軟組織的型態。本文提出一病例報告,應用牙根掩埋術達到可預期且穩定的美觀效果。

Extraction of tooth causes alveolar ridge resorption, which compromises the esthetics of anterior maxilla. Root submergence technique (RST) is a procedure that decroronates and submerges the tooth at or below the alveolar bone level, to preserve the periodontium around the defected tooth and then to prevent the aveolar bone resorption and maintain the morphology of soft tissue over it. This article presents a case that achieved the predictable esthetic outcome with this technique.
