目的:通过临床研究分析数字化咬合板与传统咬合板在正颌手术中定位上颌骨的精确性。方法:回顾性收集2017~2022年就诊于南京大学医学院附属口腔医院的成年骨性错(牙合)畸形患者,筛选具有完善术前术后影像学CT数据、牙列模型数据且已完成...目的:通过临床研究分析数字化咬合板与传统咬合板在正颌手术中定位上颌骨的精确性。方法:回顾性收集2017~2022年就诊于南京大学医学院附属口腔医院的成年骨性错(牙合)畸形患者,筛选具有完善术前术后影像学CT数据、牙列模型数据且已完成双颌正颌手术的病例18例,其中8例通过传统咬合板辅助正颌手术,10例通过数字化咬合板辅助正颌手术。根据患者术前术后影像学资料及牙列数据通过Mimics Research 20.0及3-matic Research 12.0软件完成颅骨模型重建以及牙列模型数据的替换,完成正颌手术术前、术后三维(冠状位,矢状位,轴位)方向上实际移动距离的测量。测量三维方向上术前预计移动距离与术后实际移动距离的线性差异。结果:传统咬合板组术前计划与术后实际移动平均线性差为(1.00±0.32)mm;数字化咬合板组术前计划与术后实际移动平均线性差为(0.99±0.38)mm。两种咬合板对指导正颌手术中上颌骨的三维方向的定位无显著差异。结论:数字化咬合板与传统咬合板的使用均可在正颌手术中准确定位上颌骨。展开更多
