牙体缺损达龈下的修复初探———附43例报告

Study of Restoration of Teeth with Subgingivally Involved Destruction

对４３例牙体缺损达龈下的病例采用牙髓、牙周和牙体联合治疗，随访２年，取得满意疗效。龋病或牙折裂致牙体缺损达龈下时，牙齿应先行牙髓治疗；采用临床牙冠延长术重建牙周生物宽度，防止牙周组织病变；利用牙髓腔和根管形态的不规则性和倒凹固位的银汞核钉可修复牙体形态，操作简单，经济实惠。

Combining endodontic, periodontal and restorative treatments were performed successfully on 43 cases of teeth with subgingivally involved destruction. Endodontic therapy was performed at first on patients with teeth lesions to subgingival before the crown lengthening procedure. Biologic width was reconstructed by the surgical crown lengthening. The amlcore technique was the ideal method for restoring endodontically teeth with subgingival lesions with good retention obtained from the pulp chamber and from the irregularities and undercuts in the cervical proportion of the canal.
