Abstract

The global increase in elder individuals has led to the increasing incidence of edentulous jaw cases. Thus, the increase in edentulous jaw caused by the aging population has led to personal dental health concerns. In addition, the global dental implant market is growing. In particular, the population in Korea is aging faster than those in other countries. Therefore, the growth rate of the domestic dental implant market exceeds the global average growth rate. Moreover, recipients of health insurance expanded in 2014, and the market size of dental implants is growing steeply. The growth of this market has resulted in increasing activity associated with studies related to dental implants. In the case of dental implant surgery, the duration of a patient's recovery depends on the surgical plan and physician ability. A device is required to control and assist a physician in controlling vibration and difference in operation experience, and prescribing treatment plan given the patient's condition. In this paper, the miniaturization of artificial tooth-root implant assisted robot has been studied. Structure and vibration analysis of two implant assisted robots were performed, and the structural stability was compared and analyzed. Furthermore, a virtual prototype of a artificial tooth-root implant assisted robot was produced and simulated. Hence, the state of the RCM point and driving state of the manipulator were confirmed. Drilling experiments were performed by using materials similar to a jawbone to evaluate the performance of the two implants performed with robot assistance.
