摘　　要：目的:研究在齿科设计软件中应用不同上颌颌板-上颌牙列扫描匹配方式对数字化转移上颌位置的影响。方法:使用下颌运动分析系统对10位受试者进行下颌运动记录,通过口内扫描获得上下颌数字模型及咬合关系。本实验共涉及5种上颌颌板-上颌牙列扫描匹配方式,包括:整体扫描组(ES组)、单次扫描组(SS组)与双面扫描组(DS组)、单次扫描匹配上颌组(SSU组)、双面扫描匹配上颌组(DSU组)。将口内扫描数据、上颌颌板-上颌牙列数字模型与下颌运动数据导入至CAD软件中,以完成数字化上牙合架,测量上颌左侧第一磨牙近中颊尖至虚拟牙合架左侧髁球距离、上颌右侧第一磨牙近中颊尖至虚拟牙合架右侧髁球距离、上颌中切牙近中切点至虚拟牙合架左、右髁球距离。每种方法重复3次,所得结果取平均值后进行统计分析。结果:通过上述5种方法转移的上颌位置,所测量的上颌左侧第一磨牙近中颊尖至虚拟牙合架左侧髁球距离、上颌右侧第一磨牙近中颊尖至虚拟牙合架右侧髁球距离、上颌中切牙近中切点至虚拟牙合架左、右髁球距离,无显著性差异(P>0.05)。结论:本实验选取的5种获得上颌颌板-上颌牙列数字模型的扫描匹配方式均可用于齿科设计软件中上颌位置的数字化转移。Objective:To study the effect of different maxillary plate-Maxillary arch scanning matching methods on the transfer of maxillary position in the dental computer-aided design software.Methods:Jaw movement analysis system was used to record the mandibular motion of 10 subjects.Maxillary and mandibular digital cast and occlusal relationship were obtained by intra-oral scanning.This study involved five methods,include:entirely scan group(ES),single scan group(SS),double-sided scan group(DS),single scan matched the upper jaw group(SSU),and double-sided scan matched the upper jaw group(DSU).Intra-oral scan data,maxillary plate-maxillary arch digital model,and mandibular motion data were imported into the CAD software to complete digital mounting.In the virtual articulator module,the distance from left maxillary first molar to left condylar element,distance from right maxillary first molar to right condylar element and the distance from right and left condylar elements to the incisal embrasure between maxillary central incisors were measured.Results:Among five kinds of maxillary position transferring methods,there was no significant difference on the distance from left maxillary first molar to left condylar element,distance from right maxillary first molar to right condylar element,and distance from right and left condylar elements to the incisal embrasure between maxillary central incisors on virtual articulator(P>0.05).Conclusion:Five scanning matching methods selected in this study to obtain maxillary plate-maxillary arch digital model can be used to transfer maxillary position in the CAD software.
