Since orthodontic treatments often requires several years, the aim of the paper is to provide a communication vehicle between patients and dentists prior to the treatment. The paper describes the development of a 3D animation CAI (computer assisted instruction) system, which collects many past orthodontic cases and creates a 3D animation for each case. When an orthodontist encounters a new case, a most-similar past case is selected based on the distance between the new and past cases. The 3D animation of this most similar case, which simulates the procedures like moving and morphing from pre- to post-treatment, is shown to patients. A questionnaire was performed. The results showed that most dentists and patients were satisfied with the method, the precision of the similar cases, and the systems usefulness.
