A semi- analytical model, based on the moving heat source approach combined with the method of image sources, is developed for predicting the temperature during bone drilling
Some improvements need to be made in order to better describe the cooling phase, the profiles of temperature elevations are globally reproduced by the model
Summary
Bone drilling is a common operation in orthopaedic and dental practices. This operation generates heat resulting mainly from friction between bone hole wall, chips and drill bit body. Heat generation during bone drilling exposes bone cells to elevated temperature and may result in thermonecrosis. Many experimental investigations have been conducted to characterize the optimal drilling conditions, conclusions are still uncertain and diverging (Pandey and Panda 2013). A semi- analytical model, based on the moving heat source approach combined with the method of image sources, is developed for predicting the temperature during bone drilling. An experimental drilling campaign on porcine bone samples is conducted in parallel, to validate the model
