摘要/Abstract

摘要： 目的:检验牙颌数字化模型与石膏模型在线距和角度测量方面的准确性。方法:选择一副标准牙颌模型,分别用3-shape Trios和3-shape D700扫描获取10副数字化牙颌模型、传统方法复制10副超硬石膏模型,测量其线距和角度,配对t检验检测其准确性。结果:①石膏模型、两种数字化模型与标准牙颌模型均无统计学差异,但Trios数字化模型与标准牙颌模型差异最大,石膏模型差异最小;②石膏模型及两种数字化模型之间均无统计学差异,但Trios数字化模型与石膏模型的差异最大。结论:石膏模型、D700和Trios数字化模型均表现出良好的准确性,D700数字化模型和石膏模型的准确性要略优于Trios数字化模型。

Abstract: Objective: To test the veracity of digital models and stone cast by studying the distance and angle. Methods: A dental study model was used to pour 10 sets of stone casts and scan 20 sets of digital models by 3-shape trios and 3-shape D700,respectively. The veracity of these models were tested by paired t-test through studying the distance and angle. Results: There was no difference between these models. The digital models of trios were the most different from the study model, followed by D700 and stone cast. Meanwhile, the difference between the digital models of trios and stone cast was larger than others. Conclusion: All these models showed good veracity. Furthermore,the models of D700 and the stone cast were slightly better that of Trios.

Key words: digital models, stone cast, distance, angle, veracity
