Descrição

This work aims to evaluate the generated temperature in bone tissue during a drilling process. Different clinic visits were carried out to follow-up a dental implantology and collected thermographic images for reading the temperature generated during the drilling. Simultaneously an experimental procedure was adopted with the acquisition of four blocks of Sawbones with similar properties to the trabecular and corti-cal bone and different densities. The goal of this experiment resulted in a drilling process to assess the gen-erated temperature on the drill and simultaneously on the bone material. The obtained results allow to con-clude that a more dense material reaches highest values. Regarding the temperatures recorded in the drill, the largest heating is also recorded in denser bone. In clinical practice the temperature average in the drill are lower (not exceeds 37°C) than the conducted in the experiments (42ºC for denser cortical), since the process occurs with fluids irrigation.
