| 摘 要： | 目的 探讨牙半切除术后与邻牙联冠修复保留磨牙的临床疗效。方法 对43例患者，共52颗患有个别牙根折裂、个别牙根严重的根尖周病或牙周病的磨牙，行牙半切除术后进行根管治疗及牙周治疗，3个月后根据保留牙体的缺损情况，髓腔内树脂充填或制作纤维桩核，与邻牙行联冠修复。2~3年随访，进行临床和放射学检查。结果 52颗患牙行半切除术并与邻牙联冠修复后均咀嚼功能良好，修复体稳固，冠边缘密合，牙周组织健康状况良好。X线片示有新生骨形成或无渐进性骨吸收，随访期内成功率100%。结论 牙半切除术在保留患有个别牙根折裂、个别牙根严重的根尖周病或牙周病的磨牙上有重要的临床意义，只要严格选择适应证，通过与邻牙联冠修复可以很好的恢复形态及咬合功能。

| Abstract: | Objective To explore the clinical efficacy of making union crown restoration with adjacent tooth after hemisection to repair and retain molar teeth. Methods 43 patients, a total of 52 molar teeth which have individual root fracture，or individual root with serious periodontal disease or periapical disease were involved in the study, and root canal therapy and periodontal treatment were conducted after hemisection. Three months later, whether to fill the medullary cavity with resin or to make fiber post-core were decided according to the defect case of retained tooth body, and then union crown restoration with adjacent tooth were made. After follow-up for 2-3 years, clinical and radiological examination was carried out. Results 52 teeth which were repaired with union crown restoration with adjacent tooth after hemisection all had good masticatory function, with restorations kept solid, crown edges closed, and periodontal tissue in good health. X-ray showed new bone formation or no progressive bone resorption. The success rate was 100% during the follow-up period. Conclusions Hemisection has important clinical implications on preserving molar tooth which has individual root fracture, or serious periodontal disease and periapical disease. The use of union crown restoration with adjacent tooth can be a good method to restore the teeth morphology and occlusal function as long as the indications were strictly selected. |
