    Abstract: 咬合關係是牙科產品設計的重要參考之一,不良的咬合關係會導致患者出現顳顎關節障礙與磨牙等問題。在數位牙科中可利用數位咬合器進行咬合模擬。但目前數位咬合器僅機構數位化,缺乏患者運動資訊,因此無法完全模擬患者本身運動。此外在使用流程中仰賴面弓轉移與石膏翻模,讓數位牙科流程無法完整數位化。 為改善這些缺點,本研究透過結合咬合器數學模型與下顎運動追蹤系統建立個人化下顎運動模擬系統,可用於模擬病患下顎運動。其中利用電腦斷層影像取代傳統的面弓轉移,使得數位牙科流程得以完整,並導入碰撞偵測技術以估計牙體型態改變後的咬合運動,提供醫師設計假牙、牙冠與牙橋的動態咬合參考。 本研究成果可運用於咬合板等牙科產品的設計。此外本研究設計驗證實驗以證明本研究系統用於下顎運動模擬的準確性,並由結果得知其模擬平均最大距離誤差約為 1.8mm。
    Occlusion is one of the important references to design dental product, and bad occlusion causes the problem like TMJ disorder and bruxism. In digital dentistry, digital articulator plays a role to simulate patient's occlusion. But recent digital articulator only digitalizes the mechanism of the articulator, it can't fully simulate patient's mandibular movement. Moreover, recent processs flow relies on facebow transfer and model casting which makes the flow incomplete. To overcome this shortcoming, we will build a personal virtual articulator based on tracking of mandibular movement which can simulate individual mandibular movement. We use CT data to replace facebow transfer and complete the digital flow. With collision detection, it can evaluate the occlusion or teeth interference so that the dentist can use the information to design denture or crown and bridges. Our system can be applied to the design of splint. Furthermore, we design an experiment to assess the accuracy of our system to simulate the mandibular movement of a patient. The result shows the maximum distance error is less than 1.8 mm.
