摘要/Abstract

摘要： 目的运用小视野CBCT及计算机辅助技术评价3D打印椭圆形根管的预备效果。方法对离体牙进行小视野CBCT扫描并筛选1颗合适的椭圆形单根管牙齿,将CBCT数据转换处理后,制作3D打印树脂牙模型,使用小视野CBCT扫描牙模型后保存数据。选取50名口腔全科医生,利用X-Gold机用镍钛锉系统预备树脂牙根管,小视野CBCT扫描预备后树脂牙模型。采用计算机辅助技术测量比对根管预备前后的CBCT扫描数据,通过图像的三维重建与渲染,显示椭圆形根管预备后的根管清洁度与根管偏移情况。结果 50例3D打印牙模型的根管清洁度为（56.20 ± 11.91）%,根管平均最大偏移距离为（0.140 ± 0.041）mm;根管清洁度与偏移度没有相关性（r=0.18,P=0.212）。结论小视野CBCT结合计算机辅助技术可对根管预备的根管清洁度与根管偏移情况实现有效的定量评价。

Abstract: Objective To evaluate the effect of 3D-printed oval root canal preparation by using small field-of-view cone beam CT (CBCT) combined with computer-aided technologies.Methods An extracted tooth with a suitable single oval canal was selected by small field-of-view CBCT scanning. Three-dimensional (3D)-printed resin teeth were obtained based on the CBCT data after data conversion and processing. 50 general dentists were selected to prepare the oval root canal of the resin teeth with X-Gold rotary Ni-Ti instruments. Small field-of-view CBCT was applied to scan the oval root canals before and after preparation. Then, computer-aided technologies were used to calculate and compare these CBCT data, analyzing the effects of oval root canal cleaning as well as the root canal deviation by 3D reconstruction and rendering of the images.Results Among the 50 cases, the mean unprepared area of the oval root canal wall was（56.20 ± 11.91）% and the mean maximum deviation distance of the root canal was（0.140 ± 0.041）mm. There was no correlation between root canal cleanliness and deviation (r=0.18, P=0.212).Conclusion Combined with small field-of-view CBCT and computer-aided technology, we can effectively quantitatively evaluate the root canal preparation effect.
