纯钛板用于肿瘤术后下颌骨缺损的修复已成趋势，有关钛板的性能、修复后颌骨组织的反应及固定方式已有大量报道。业已肯定，钛—骨之间可达到直接的生物性结合（骨整合）。本研究通过动物实验以扫描电镜观察γ射线照射对这种钛—骨结合的影响，以论证钛板修复后放射治疗的可行 Pure titanium plate for the repair of mandibular defects after surgery has become a trend, the performance of the titanium plate, the response of the mandibular tissue repair and fixation has been extensively reported. It has been confirmed that direct biological binding (osseointegration) between titanium and bone can be achieved. In this study, animal experiments to observe the effect of γ-ray irradiation on the titanium-bone binding by scanning electron microscopy to demonstrate the feasibility of radiotherapy after titanium plate repair
