摘　　要：目的 设计并三维打印用于单块颏成形术的导板系统,评估其临床应用的准确性,以期为临床提供参考.方法 选取2014年7月至2016年3月于上海交通大学医学院附属第九人民医院就诊的36例需接受双颌手术及颏成形术治疗的患者.设计用于颏成形术的导板系统,包括截骨导板及定位导板,三维打印导板实物,指导术中方案实施.将术后CT重建模型与术前计划相比,对颏骨块空间位置的准确性进行评估.结果 所有颏成形术均顺利完成.术前规划与术后实际颏部骨段空间定位的最大位移均方根偏差为1.16 mm,最大角度均方根偏差为3.06°,在临床可接受范围内.结论 该颏成形术导板系统可取得较好的手术准确性,是一种将术前虚拟方案转化至术中实际的可靠方法.Objective To develop and validate a new genioplasty templates system for monoblock osseous genioplasty.Methods Thirty-six patients with chin deformities were enrolled in this study.The chin template system included a cutting guide and a repositioning guide for a genioplasty.Chin templates were designed in a computer and fabricated using a three-dimensional printing technique.The accuracy of the genioplasty templates were assessed by comparing the actual postoperative outcomes with the virtual plan.Results All genioplasty was successfully completed by the template system.The largest linear rootmean-square deviation（RMSD） between the planned and the postoperative chin segments was 1.16 mm and the largest angular RMSD was 3.06°.Conclusions The results showed that the chin template system provides a reliable method for transfer of genioplasty planning.The operation precision of the genioplasty can be improved by using the surgical templates system.
