Abstract

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
