摘要/Abstract

摘要： 目的： 比较2种CAD/CAM口腔数字化导板的精度。方法： 选择上海市静安区牙病防治所就诊的36例口腔种植患者,均行CBCT检查和口内激光扫描,所获数据导入3Shape软件,进行术前设计。每个病例生成2个导板,A导板数据来自CBCT,B导板数据为CBCT和口内激光扫描数据的拟合,随机选择导板类型并使用。术后拍摄CBCT并将数据导入设计软件,与种植前设计的位置进行比较。采用R语言4.1.0对数据进行统计学分析。结果： B导板组种植体顶部中心点距离偏差、种植体底部中心点距离偏差和两中心点连线的角度偏差显著小于A导板组（P<0.05）。结论： CBCT和口内激光扫描数据拟合生成的CAD/CAM口腔数字化导板精度更高,有利于提高种植体植入的三维位置精确度。

Abstract: PURPOSE: To compare the accuracy of 2 kinds of CAD/CAM dental digital guides in dental implantation. METHODS: A total of 36 patients with oral implants from Dental Disease Prevention and Control Institute of Shanghai Jing’an District were selected for CBCT examination and intraoral laser scanning. The data obtained were imported into 3Shape software and designed before operation. Two guides were generated in each case. Data of A guide plate came from the fitting of CBCT, while data of B guide plate for CBCT and intraoral laser scanning, and the type of guide plate was randomly selected and used. After operation, CBCT was taken and the data were imported into the design software, and the position of the design before implantation was compared. R software (version 4.1.0) was used for data analysis. RESULTS: The distance deviation of the top center point of the implant, the distance deviation of the center point at the bottom of the implant and the angle deviation of the line connecting the two center points in B guide plate group were significantly lower than those in A guide plate (P<0.05). CONCLUSIONS: The accuracy of CAD/CAM dental digital guide plate generated by the fitting of CBCT and intraoral laser scanning data is higher, which is helpful to improve the accuracy of three-dimensional position of dental implant.
