Biomedical Simulation

Abstract

Training systems for dental implantology that are based on virtual reality need a precise haptic feedback with six Degrees of Freedom (6DoF) This is particularly challenging when using real patient data for the jawbone and during the interactive simulation of drilling. In this paper, we present our simulator and two complementary contributions: The first one is a method for 6DoF haptic rendering of contacts between the drilling tool and the jawbone model issued from a CT-scan. The second one is a fast simulation of the jawbone erosion during drilling which is relevant for 6DoF haptic rendering.
