6例种植体植入后早期失败原因分析及补种成功治疗体会

Analysis of early dental implant failure and retreatment of 6 cases

目的:回顾分析种植体植入后早期失败的原因、失败后再次种植的治疗措施。方法:对6例种植体植入后早期发生感染、松动等未实现骨结合的病例进行回顾,从临床表现、脱落原因、2次种植治疗等方面分析,并对失败原因进行探讨、对再种植疗效进行评估。结果:2例失败原因为邻牙牙髓、根尖周病和种植体周围感染拔除原种植体后行种植窝刮治、抗炎、邻牙根管治疗和再次种植术;4例为种植体无骨结合,原种植窝处理后6个月再次植入种植体;6例均重新实现种植体骨结合。结论:种植体失败的预防措施应包括控制邻牙和牙周感染因素以及适应证的选择;种植失败后对原种植窝有效处理后再种植仍能取得良好的种植疗效。

Objective：To analyse the causes of early implantation failure and the therapeutic measures with re-implantation after the failures.Methods：6 cases of implantation failure including early infections,loosening and non-osteointegration were reviewed and trea-ted by re-implantation therapy,and the causes of failure were discussed and the effects of re-treatment were evaluated.Results：2 cases were found to be with infection of adjacent teeth after implantation and were treated by removal of the implant,socket curettage,root ca-nal therapy（RCT）and antibiotics followed by reimplantation.Implant loosening and non-osteointegration were observed in 4 cases, which were treated by the similar methods for the implant socket.Reimplantation was successful in all 6 cases followed-up for 1 -3 years.Conclusion：Preventive measure for implantation failure should include indication selection,control of infections in adjacent teeth and periodontosis,use of GBR technic and so on.Re-implantation following proper treatment of adjacent teeth and the socket of implant is effective for the treatment of implantation failure.
