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 cortical bone and different densities. The obtained results allow to conclude that a denser material reaches highest values of temperature during a drilling process, namely, bone density is directly proportional to the temperature. In relation to temperatures recorded in the drill, the largest heating is recorded in drilling of denser bones. At the clinic, the average values of temperature are lesser when compared to the drill conducted in laboratory, because the process occurs with fluids irrigation.
