目标。其目的是比较三维虚拟(3D-VMS)和传统手工方法(MMS)在模型手术和中间晶片(IW)制造中的准确性。研究设计。25例患者根据上颌有无前后移位(第1组和第2组)和倾斜矫正情况(第3组和第4组)进行了分组。在MMS和3D-VMS之后，制作了常规IW和3D虚拟IW(3D-VIW)。使用这些IWS和3D位置将附加的上颌模型安装在牙合架上，并对3D位置进行统计分析。在模型手术中，虽然3D-VMS比MMS更准确，但两种方法的误差在所有组均小于1 mm。在晶片制造中，垂直变化仅在组1、组2和组3有显著差异。模型手术和晶片制造方法在精度上没有显著差异。三维VMS较MMS更准确。然而，3D-VIW制作的精度还有待提高。《口腔外科》《口腔医学》《口腔病理学》《口腔放射学》2009；107：13-21
Objective. The aim was to compare the accuracy of 3-dimensional virtual (3D-VMS) and conventional manual methods (MMS) for model surgery and intermediate wafer (IW) fabrication.Study design. Twenty-five patients were divided according to presence or absence of anteroposterior movement ( groups 1 and 2, respectively) and canting correction ( groups 3 and 4, respectively) of the maxilla. After MMS and 3D-VMS, conventional IW and 3D virtual IW (3D-VIW) were fabricated. Additional maxillary casts were mounted on the articulator using these IWs and 3D positions, and the 3D positions were statistically analyzed.Results. In model surgery, although 3D-VMS was more accurate than MMS, the errors of both methods were less than 1 mm in all groups. In wafer fabrication, vertical change only was significant in groups 1, 2, and 3. Model surgery and wafer fabrication methods did not show significant differences in accuracy.Conclusion. Three-dimensional VMS was more accurate than MMS. However, the accuracy of 3D-VIW fabrication needs to be improved. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009; 107: 13-21)
