正顎手術依顱式上顎定位導板透過3D列印及模擬技術，定位上顎骨位置，以利達成精準地正顎手術。傳統上利用下顎骨去定位上顎骨的做法，由於下顎骨的移動性，較易導致穩定性和準確性問題。再者，上下顎牙弓之間的不協調與位置落差，更會使正顎手術的操作性及不精確性增加困難。藉由我們設計的依顱式上顎定位導板，透過解剖構造直接由非游離移動地構造去定位上顎骨，可以提高手術精度並節省手術時間。
此設計另一的關鍵創新在於使用顴骨支撐固定游離後的上顎骨，與傳統方法相比增強了穩定性和且較易於固定。
The OgS Craniomaxillary Position Guide enhances orthognathic surgery by accurately positioning the maxillary bone.
Traditional methods using the mandible and intermediate wafer can lead to stability and accuracy issues due to the mandible's mobility. Discrepancies between mandibular and maxillary arches can result in cumbersome wafers, complicating oral operations. Directly aligning the maxilla through cranial landmarks, as proposed, enhances surgical precision.
The design's key innovation lies in securing the mobilized maxillary bone using the zygomatic buttress, enhancing stability and ease of fixation compared to conventional methods.
