UNLABELLED
The aim of this study is to analyze the success of extraoral osseointegrated implants used to support designed to rehabilitate craniofacial deformities.
METHOD
This study was based on the retrospective assessment of charts from 59 patients submitted to cancer surgery and who received 164 extraoral implants to contain facial prosthesis.
RESULTS
Among 164 implants, 42 were fixed in previously irradiated regions. Eight of the implants did not have osseointegration; and from these, two were fixed in irradiated bone. The result show 116 (95.1%) successfully osseointegrated implants in non-irradiated sites. The success rate among 42 implants fixed in previously irradiated bones was 40 (95.3%) osseointegrated implants.
CONCLUSION
The use of extraoral craniofacial implants represents a safe and effective approach to treat facial deformities as a support for the rehabilitation prosthesis. Radiotherapy treatment does not prevent osseointegration.
目的
本研究旨在分析用于支撑颅面畸形修复的体外种植体的成功率。
方法
本研究基于对 59 名接受癌症手术并接受 164 个体外种植体以容纳面部假体的患者图表的回顾性评估。
结果
在 164 个种植体中，42 个固定在先前放射治疗区域。其中 8 个种植体没有骨整合；其中 2 个固定在放射治疗的骨中。结果显示，在非放射治疗部位成功骨整合的种植体有 116 个（95.1%）。在固定在先前放射治疗骨中的 42 个种植体中，有 40 个（95.3%）成功骨整合。
结论
颅面外种植体的使用是一种安全有效的方法，可作为修复假体的支撑来治疗面部畸形。放射治疗不会妨碍骨整合。
