Abstract

In some specific maxillo-facial surgeries, like the Epker, the cortical part of the lower maxilla must be drilled with minimum penetration into the spongy bone to avoid the trigeminal nerve. The result of the surgery is highly dependent on the quality of the drill. Drilling must therefore be mastered by students before acting as surgeon.

The study compares the efficiency of two punctual drilling training programs developed on a virtual reality platform with non medical participants. The results show better benefit of training on relevant haptic aspects of the task before introducing multimodal drilling over repeated multimodal simulated drilling exercises.
