A denial student is required to gain practical experience as well as theoretical training at the early stage of their training. In order to restore a decayed tooth, fundamental dental procedures are necessary, including: 1. Identification of caries using a sharp denial probe, where the probe physically is inserted a short distance into the caries to observe properties such as volume; 2. Unhealthy tissues must be removed by drilling operation or probe. 3. Complete the restoration procedure by filling in composite resin such as light cured photopolymer. All of these procedures require a high degree of dexterity. Traditional training involves a real denial patient or human head-like dummy model, which pose several distinctive disadvantages such as safety, examination across students, high maintenance cost as well as the recording and feedback of the procedures. A haptic dental training system provides a viable solution to these challenges. This thesis explores the key process in tooth restoration and the development of a new haptic rendering algorithm. These include the development of the mathematical model to identifying material with a short distance insertion probing and filling operation with resin. It also presents a novel hardware design of a dental training system, which allows a student to perform a haptic drilling operation, with a hand-eye collocated gesture. Large scale evaluation of the system is done and results are presented.
