Description

The main goal of this paper is to present a numerical model for studying the thermal necrosis due a dental drilling process. The finite element method was used with Ansys program for the transient thermal analysis. Also an experimental process is explained to determine the thermal occurrence in a pork mandible. The in-crease of temperature produced during the drilling is compared using the two different methodologies. According the obtained results, the numerical model could be a technique to induce appropriated results with-out using in-vivo models.
