BACKGROUND
We investigated dental implant outcomes in patients who had previously received radiotherapy (RT) for head and neck malignancies.
METHODS
We reviewed 90 dental implants in 27 patients who received RT for head and neck cancer and received dental implants afterwards. The cumulative implant survival rate (CISR) was calculated. In addition, the implant quality was assessed using "Health Scale for Dental Implants."
RESULTS
The CISR at 3 years was 79.6%. The mean radiation dose at the implant site (D ) was identified as an independent prognostic factor for implant survival. No implant failed if D was less than 38 Gy. Regarding implant quality, dental implants in grafted bone and D were independent risk factors.
CONCLUSIONS
D was identified as an independent prognostic factor for implant survival and quality. Dental implants can be safely considered when D is lower than 38 Gy.
背景
我们研究了先前因头颈部恶性肿瘤接受过放射治疗（RT）的患者的牙种植体预后。
方法
我们回顾了 27 例头颈部癌症接受 RT 后接受牙种植体的患者的 90 颗牙种植体。计算了累积种植体存活率（CISR）。此外，使用“牙种植体健康量表”评估了种植体质量。
结果
3 年时 CISR 为 79.6%。种植部位的平均照射剂量（D）被确定为种植体存活的独立预后因素。如果 D 小于 38Gy，则没有种植体失败。关于种植体质量，骨移植中的种植体和 D 是独立的危险因素。
结论
D 被确定为种植体存活和质量的独立预后因素。当 D 低于 38Gy 时，可以安全地考虑使用牙种植体。
