BACKGROUND
The purpose of this systematic review was to evaluate the safety of dental implants placed in irradiated bone and to discuss their viability when placed post-radiotherapy (RT).
METHODS
A systematic review was performed to answer the questions: "Are dental implants in irradiated bone viable?" and "What are the main factors that influence the loss of implants in irradiated patients?"
RESULTS
The search strategy resulted in 8 publications. A total of 331 patients received 1237 implants, with an overall failure rate of 9.53%. The osseointegration success rates ranged between 62.5% and 100%. The optimal time interval between irradiation and dental implantation varied from 6 to 15 months.
CONCLUSION
The interval time between RT and implant placement and the radiation doses are not associated with significant implant failure rates. The placement of implants in irradiated bone is viable, and head and neck RT should not be considered as a contraindication for dental rehabilitation with implants. © 2015 Wiley Periodicals, Inc.

背景
本系统评价的目的是评估植入受照射骨内的牙种植体的安全性，并讨论放疗后植入牙种植体的可行性。
方法
进行系统评价以回答以下问题：“植入受照射骨内的牙种植体是否可行？”以及“影响接受放疗患者种植体脱落的主要因素有哪些？”
结果
检索策略共得到8篇出版物。共有331例患者接受了1237颗种植体，总体失败率为9.53%。骨结合成功率在62.5%至100%之间。放疗与牙种植之间的最佳时间间隔为6至15个月。
结论
放疗与种植体植入之间的间隔时间和辐射剂量与显著的种植体失败率无关。在受照射骨内植入种植体是可行的，头颈部放疗不应被视为牙种植体修复牙齿的禁忌证。©2015威利期刊公司。《头颈》38: E2229 - E2240，2016年。
