Abstract
The bone quality of trabecular bone affects the acheivement of the oral implant surgery, however its priori estimatation is difficult and the doctors have to confirm it from force sensation during the surgery. In this reasarch, the reaction-force sensible equipment has been proposed to inherit this feeling to the young doctors by using an actuator, a database and an actual drill. By forcing the top of the actuator, using the drill, the input force is measured and is transferred to the database, which is constructed by considering the characteristic of trabecular bone using FEM anlayses. Then the database gives back the drilling speed, depending on how much force is applied, to the actuator. Due to the use of the actual surgical device, the doctors are able to feel the weight, the vibration, and hear the sound, and therefore they feel as if they are in real surgery.
