PURPOSE
To investigate the clinical effect of repairing posterior residual crown using titanium alloy post combined with composite resin core technique.
METHODS
Twenty-one patients (26 residual crown) with perfect root canal therapy were selected. Modern bonding technique was used to build up the core with titanium alloy post and flow composite resin together for crown restoration.
RESULTS
After ten years of clinical observation, only 4 cases among the 21 patients failed in restoration. The rate of success was 85%. X-ray showed that the periapical alveolar bone density was enhanced after restoration.
CONCLUSIONS
Standard root canal therapy and effective post-core strengthening can restore the function of the residual crown and retain the tooth.
目的
探讨钛合金桩联合复合树脂核技术修复后牙残冠的临床效果。
方法
选取21例根管治疗完善的患者（26颗残冠），采用现代粘结技术，用钛合金桩和流动复合树脂一起构建核，进行冠修复。
结果
经过10年临床观察，21例患者中仅4例修复失败，成功率为85%。X线显示修复后根尖牙槽骨密度增强。
结论
规范的根管治疗和有效的桩核强化可恢复残冠功能并保留患牙。
