“…Three evaluators with more than 10 years of university teaching experience evaluated the products of both haptic and conventional simulators. The evaluation items were those that can be measured with both haptics and conventional simulators, referring to previous reports: 20 (1) Is the occlusal surface form of the abutment similar figure of original occlusal surface (hereafter, “Occlusal surface form”), (2) Is the margin design light chamfer (hereafter, “Margin design”), (3) Is the preparation surface smooth (hereafter, “Surface smoothness”), (4) Is the taper appropriate (hereafter, “Taper angle”), and (5) Is the total cut volume appropriate (hereafter, “Total cut volume”). Each item was scored on a 5-point rating scale (5: good, 4: somewhat good, 3: undecidable, 2: somewhat poor, 1: poor).…”

Background/purpose The haptic 3D virtual reality dental training simulator has been drawn attention as a educational strategy in Covid-19 pandemic. The purpose of this study is to investigate the feature of the haptics simulator in comparison with a conventional mannequin simulator by analyzing the assessment of products prepared by dental students using these two kinds of simulator. Materials and methods The subjects were 30 students in the sixth-year classes of the faculty of dentistry. Abutments for a full cast crown were prepared by each subject using two kinds of simulator; one is the haptics simulator and the other is a mannequin simulator. For the resulted products, occlusal surface form, margin design, surface smoothness, taper angle, total cut volume and overall impression were rated by 3 evaluators. Score differences between two simulators were statistically analyzed. Results The kinds of simulator affected subject performance for margin design and total cut volume. The differences in cutting feeling between the simulators as well as variation of stereoscopic ability in subjects were considerable reasons. Evaluators’ rating was affected by difference in simulators for occlusal surface form, total cut volume, and overall impression. This may have been due to variation of stereoscopic ability in evaluators. Conclusion The unique characteristics of virtual reality, such as the simulated cutting sensation and the simulated three-dimensional images created by stereo viewers, affect operators’ performance and evaluators’ rating. It was suggested that educational programs need to be constructed taking account of the characteristics of virtual reality to make the best use of the haptics simulator.
