3D打印导板辅助髁突骨软骨瘤及继发复杂牙颌面畸形的手术治疗
|
Abstract:
摘要 目的:研究3D打印手术导板辅助髁突骨软骨瘤及继发牙颌面畸形同期矫治的临床可行性。方法:根据影像学资料,运用Dolphin Imaging 11.7 Premium 和Mimics软件进行虚拟外科手术设计并制作3D打印手术导板,指导髁突骨软骨瘤及继发牙颌面畸形的手术矫治。通过对比模拟头颅模型与实际术后CT重建模型评估此方法的临床价值。结果:所有患者患侧关节功能、咬合关系以及颜面对称性都得到了良好的恢复。模拟术后模型与术后扫描重建模型对比中,中切牙与第一磨牙的误差均保持在1.4 mm以下,最大误差出现在颏部,约2.4 mm,显示了新方法的准确性。结论:结果显示虚拟外科手术设计和手术导板有助于髁突骨软骨瘤继发牙颌面畸形的准确诊断、治疗方案设计、准确截骨以及重置骨块
