摘　　要：目的:明确逆行性种植体周围炎与根管治疗后邻牙的关系。方法:对32例(39枚种植体:ITI28枚,MDIC11枚)邻牙根管治疗后种植体植入患者进行病例回顾性研究,分别对邻牙根管治疗后的时间进行记录,测量X线片中种植体与邻牙的距离。结果:39枚种植体中有10枚出现逆行性种植体周围炎症状,其中8枚(6枚ITI,2枚MDIC)邻牙是根管治疗完成时间不足3个月(P<0.05),X线片显示与邻牙的距离都小于3mm(P<0.05)。结论:邻牙根管治疗后至少3个月的观察时间进行种植体手术,控制好种植体与邻牙的距离是预防逆行性种植体周围炎发生的有效手段。Objective：Through the cases retrospective study, to analyze the correlation between the adjacent endodontic teeth and the retrograde implantitis. Methods： 32 patients were selected and there were 39 implants （ ITI 28, MDIC 11 ） , which adjacent teeth had received endodontic therapy. Record the time from endodontic therapy and the distance of the apex of implants to the adjacent tooth by X-ray photograph. Results： There were 10 implants with retrograde peri-implantitis of 39 implants. In 8 implants, their adjacent teeth received root canal therapy within 3 months （ P 〈 0.05 ）. The distance was shorter than 3 mm in 7 retrograde peri-implantitis （ P 〈 0.05 ）. Conclusion： Increasing the interval of the adjacent endodontic therapy to the insertion of implants and the distance between the implants and the adjacent teeth can avoid retrograde peri-implantitis.
