Simulation Learning

VRDent is the name of a collaborative project between the School of Dentistry and the UM3D Lab, the goal of which is to develop an advanced digital training model for students in the School of Dentistry. The ultimate goal is to incorporate a 3D display with a haptic feedback device to simulate cavity preparation or other common dental hand skills.
 
The VRDent team is working on a prototype computer program that uses 3D models to allow students to simulate cavity preparation procedures taught in the preclinical courses. We have identified a digital sculpting program, ZBrush, to present the simulation models. ZBrush combines 3D/2.5D modeling, texturing and painting. Using ZBrush with digitized models of the Form 1 block and anterior and posterior teeth, students can “cut” the outline form of assigned cavity preparations. The ultimate goal of the project is to develop a low-cost simulator using sophisticated software that operates on standard PCs, with the potential for Web-based options, and does not require complicated training.
