3D客製化正顎手術(上下顎)

顴骨削骨

下顎骨角削骨

下巴雕塑

雙側咀嚼肌打薄

這位患者的主訴是想改善嘴凸、臉寬和臉方(國字臉)的感覺。

經過我們電腦斷層的檢查與分析，她的臉型診斷包括上顎輕微前突、下顎輕微後縮、輕微深咬、咬合平面輕微歪斜、下顎骨角過方、咀嚼肌肥大以及顴骨外擴等等。

雖然每個部位都是輕微異常，也完全不影響咬合功能，但加總起來的效果，就足以讓臉型形成一種嘴凸臉方的感覺。

我們對她的臉型設計規劃，包含雙顎正顎手術合併顴骨削骨(縮窄)加上下顎削骨合併雙側咀嚼肌打薄以及下巴雕塑手術，順時針旋轉咬合平面，

除了增加微笑曲線外，也讓下巴及下顎線條更加俐落。

手術後，她很喜歡這樣的臉型變化，變得甜美、精緻。

附上術前及術後六個月的電腦斷層比較，這原本是一個手術優先(加上術後牙齒矯正)的案例。

但手術後，她對於咬合的改變覺得非常適應，並未接受術後的牙齒矯正治療。

This patient’s chief complaint was to improve the appearance of a protruding mouth, a wide face, and a square-shaped face.

After CT examination and analysis, her facial diagnosis included mild maxillary protrusion, mild mandibular retrusion, mild deep bite, slight occlusal plane cant, overly square mandibular angles, hypertrophic masseter muscles, and zygomatic bone flaring.

Although each condition was only mildly abnormal and did not affect occlusal function at all, the combined effect was enough to create the impression of a protruding mouth and square face.

Our facial design included bimaxillary orthognathic surgery combined with zygomatic and mandibular contouring, as well as chin sculpture, with clockwise rotation of the occlusal plane. This not only enhanced the smile curve but also made the chin and jawline more defined. Postoperatively, she was very pleased with the facial changes, which gave her a sweeter and more refined appearance.

We have attached CT comparisons before surgery and six months after surgery.

This was originally a surgery-first case (followed by postoperative orthodontics), but after surgery she felt very well adapted to the changes in occlusion and did not undergo orthodontic treatment afterward.
