摘要： 目的: 设计并通过3D打印的方法制造用于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: 接受颏成形术治疗的患者12例,平均年龄22.6岁(18~27岁)。所有患者术前均行头颅CT扫描,将CT数据导入Mimics 16.0,重建出下颌骨的三维模型,用3-matic 8.0设计截骨导板和定位导板,设计好后采用光敏树脂用三维打印机打印制作,在术中应用。结果: 所有患者均釆用3D打印的导板完成截骨,术中导板置入顺利,未出现碎裂、变形等问题。所有颏成形术均顺利完成。与术前规划相比,术后实际中心点冠状向、矢状向和垂直向位移分别为(0.12±0.27)mm、(-0.57±0.18) mm和(-0.22±0.36) mm,差异无统计学意义;俯仰角、侧滚角和偏航角分别为(2.14±1.02)°、(0.45±0.64)°、(0.24±0.17)°, 差异无统计学意义。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,外科医生可以使用此技术来获得更好的手术效果。

Abstract: Objective: To guide the genioplasty and illustrate its feasibility and validity by a new 3D printing template. Methods: Twelve patients with microgenia deformities were included. The mean age at the time of surgery was 22.6 years (range 18-27 years). Cone beam CT scan was used for each patient to create a 3D mandibular model. The templates were designed in 3-matic 8.0 software and manufactured via 3D printing technique. Results: All patients were operated with the novel method successfully without plate break or deformity. Compared to preoperative virtual position, the actual central point movement distance was (0.12±0.27) mm coronally, (-0.57±0.18) mm sagitally, and (-0.22±0.36) mm perpendicularly, respectively. The angular of pitch, roll, and yaw were (2.14±1.02)°, (0.45±0.64)°, and (0.24±0.17)°, respectively. There was no significant difference statistically. Conclusion: This templates 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 and better outcome can be available.
