咬合不正是一種非常普遍的口腔疾病，齒顎矯正則可針對咬合不正的病患進行治療，使他們能夠恢復正常咬合。但因為在齒顎矯正的治療過程中，常常必須花費好幾年的時間才能完成，因此在治療前醫生及病患雙方必須進行溝通，達成共識後才能治療，這時若有治療模擬及3D動畫的輔助就可以提供醫病雙方一個良好的溝通管道。在本研究中，我們提出了一個電腦輔助教學系統架構，其結合了案例推論技術，並針對齒顎矯正案例進行搜尋。該教學系統匯集很多過去的齒顎矯正臨床案例，並將每一個案例製作成3D動畫，模擬出治療前以及治療後牙齒的移動及變形狀況。當醫生面對一個新案例時，系統會計算出新案例及舊案例間的差距，以找尋出相似案例，並將3D動畫播放出來供醫生及病患觀看。本系統也納入了病理規則將各種案例進行分類，基於這些規則，也讓案例的搜索範圍變小，使搜尋速度更加快速。本研究之研究成果，提供醫病雙方一個更方便且有效的溝通工具。

Malocclusion is a very common oral disease. People with malocclusion often appeal to orthodontics for treatment. Since the treatment of orthodontics often takes several years, simulation and animation with 3D visual effect provides a good communication vehicle between patients and dentists before the treatment. In this paper, we developed a framework of CAI (computer assisted instruction) system with case-based reasoning for orthodontics. The system collects a lot of past cases of orthodontic and makes a 3D animation for each case, which simulates the moving and morphing from the pre- to the post-treatment. When a dentist encounters a new case, a past case will be selected based on the distance between the new case and the past one. A 3D animation of this most similar case will also be displayed. The system also incorporated pathological rules used for classifying the cases with different symptoms. Based on the rules, the search space for the similar cases can be reduced. It provides a more convenient and efficient tool for communication.
