摘要

牙周補綴治療上較困難的臨床問題主要是和臼齒根叉解剖形態、根叉齒槽骨病變的診斷與治療。一般而言,根叉齒槽骨病變患齒,尤其是帶有狹窄根叉入口的進行性牙周炎之臼齒,如果根叉區域無法有效的牙菌斑控制或是沒有治療,則預後極差。此外，這種狹窄根叉入口徑的根叉齒槽骨病變欲當做橋基牙時,則保留橋基牙的目的相形重要。因為橋基牙的喪失,將會造成許多不易克服的補綴設計問題。本文提出有關下顎第二大臼齒根叉齒槽 骨病變合併根叉入口徑狹窄的牙齒分割合併牙冠隧道穿通術的牙周補綴治療。結果顯示這種改良法的效果佳。不啻是另一種針對狹窄根叉入口的根叉齒槽病變患齒的最新療法。

Difficult clinical problem in periodonticprosthodontic therapy induded the knowledge of furcation anatomy, diagnosis and treatment of an involved furcation. Especially in the advanced localized periodontitis of molar with narrow furcation entrance diameter if un treated, the prognosis is poor, unless the oral hygieneis optimal in the furcal area. Furthermore, the loss of an only distal abutment in the mandible can create an almost insurmountable restorative problem. therefore, It is important to keep the molar as a strategic abutment. This paper reports the root separation and tunneling therapy for the furcation treatment of mandibular second molar with narrow furcation entrance diameter. Result reveals that root separation and tunneling therapy can be another valuable tfeatment of furcation involvement. Molar teeth treated by his modality can be used as a strategic abutment for fixed bridge.
