- 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.
- The main goal of this work is to evaluate the developed temperatures in bone tissue due to a drilling process, and verify the hypothesis of the thermal necrosis occurrence. Experimental methods were used in the laboratory based on the use of thermography and thermocouples during bone drilling in different materials. The follow-up of patients was also performed during the dental implants placement for data collecting from thermographic images.
- 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.
