骨性第三类型咬合不正
上下颚骨的前後差距大
发音、咀嚼功能的严重障碍
下眼眶骨支撑不足

3D客制化正颚手术
3D客制化下眼眶骨重建
这位患者(陈医师)本身是一位在美国执业的专业牙科医生，谘询过许多在美国的正颚手术医师，但对於他们的治疗计画似乎没有很有信心，最後经过台湾亲友的推荐找到我们。
於是我们开始跨海与他在美国的矫正科医师(Dr. Russ Trapnell)进行数次详细的讨论。
这个case的挑战之处，除了上下颚骨的前後差距非常大之外，上颚骨的高度也严重不足，导致他在咬合时，非常吃力，下颚骨也会异常抖动，造成他发音、咀嚼功能的严重障碍，经过长期的用力过度咬合，也咬出深深的法令纹。
我们手术计画，包含较积极的上颚延长及前移，如此一来可以给上唇及中脸更多的支撑，也可以降低下颚骨的後移量，保留了呼吸道空间，而在做上颚骨的同时，我们利用同一个伤口，做了下眼眶骨的重建，一并改善了泪沟及苹果肌的凹陷。
术後的结果非常稳定，他感到咬合比较不吃力，下颚也不再抖动，法令纹也逐渐的淡化中，手术数周後，他如期回到美国执业，以及接受术後的牙齿矫正治疗。
This patient, Dr. Chen, is a professional dentist practicing in the United States.
He had consulted several orthognathic surgeons in the U.S. but did not feel confident in their treatment plans.
Eventually, through the recommendation of friends and family in Taiwan, he reached out to us.
We began an international collaboration and held several in-depth discussions with his orthodontist in the U.S., Dr. Russ Trapnell.
The challenge in this case stemmed not only from the significant discrepancy between the upper and lower jaw positioning, but also from the severe deficiency in the height of the upper jaw.
This made biting extremely strenuous and caused abnormal tremors in the lower jaw, which led to serious impairments in speech and chewing. Over time, excessive effort in biting even resulted in deep nasolabial folds.
Our surgical plan included a more aggressive approach to lengthening and advancing the upper jaw, providing greater support to the upper lip and midface.
This also reduced the extent of lower jaw repositioning, helping to preserve airway space.
During the upper jaw surgery, we utilized the same surgical site to reconstruct the inferior orbital rims, simultaneously improving the tear troughs and volume loss in the cheek area.
Post-surgery, the results were highly stable. He reported less strain during biting, no further tremors in the lower jaw, and a gradual softening of his nasolabial folds.
A few weeks after the surgery, he returned to his practice in the U.S. as scheduled and began his post-operative orthodontic treatment.
