    ABSTRACT: It is widely accepted that a reform in medical teaching must be made to meet today's high volume training requirements. Receiving pre-training in a core set of surgical skills and procedures before novice practitioners are exposed to the traditional apprenticeship training model where an experienced practitioner must always be present, can reduce both skill acquisition time and the risks patients are exposed to due to surgeon inexperience. Virtual simulation offers a potential method of providing this training and a subset of current medical training simulations integrate haptics and visual feedback to enhance procedural learning. The role of virtual medical training applications, in particular where haptics (force and tactile feedback) can be used to assist a trainee to learn and practice a task, is investigated in this thesis. A review of the current state-of-the-art summarises considerations that must be made during the deployment of haptics and visual technologies in medical training, including an assessment of the available force/torque, tactile and visual hardware solutions in addition to the haptics related software. An in-depth analysis of medical training simulations that include haptic feedback is then provided after which the future directions and current technological limitations in the field are discussed.

    ABSTRACT: Techniques of virtual simulation have been used to teach junior surgeons how to do a cheiloplasty, but still do not meet the trainees' demands. We describe a CAD/CAM silicone simulator, which we made using several maxillofacial prosthetic techniques. An optical scanning system was used to collect the data about the cleft lip. Reverse engineering software was then used to build the virtual model, and this was processed in wax by machine. The definitive simulator was made with prosthetic silicone and extrinsic colourants. The surgical trainees practised the basic skills of cheiloplasty on the simulator, and proved its worth. Copyright © 2014 The British Association of Oral and Maxillofacial Surgeons.
