摘要

拔牙後齒槽脊經歷生理性吸收，往往會造成日後假牙製作上美觀的缺陷，特別是上顎前牙區。良好高度和寬度的骨脊，有利製作外觀自然之橋體，且不易堆積牙菌斑。針對骨脊缺陷造成的美觀問題，可利用假牙製作或是手術方法矯正。長的橋體或粉紅陶瓷牙齦可解決此類骨脊缺陷美觀問題。手術方面，臨床上以人工骨粉，再生膜，或是軟組織進行骨脊豐隆術以改善無牙區骨脊塌陷的問題。本篇病例討論為利用同種異質移植體合併軟組織進行上顎前牙無牙區之骨脊豐隆術。

Alveolar bone resorption is the normal physiologic response following tooth extraction. Ridge defects present important challenges for esthetic dentistry, especially the upper anterior esthetic zone. The ideal ridge height and width allows placement of a natural looking pontic which facilitates maintenance of plaque-free environment. There are various other prosthetic and surgical options for improving esthetics in the patient with ridge deformities. Long pontic design or gingival (pink) ceramic in the cervical region can enhance esthetics in such cases. Surgical procedures using bone graft, membrane and soft tissue graft can correct such type of ridge defects. This article demonstrates ridge augmentation with allograft and subepithelial connective tissue graft in anterior esthetic pontic zone.
