A 46-year-old male Caucasian with traumatically induced maxillary retrusion was referred for orthodontic treatment, eight weeks after the original fracture had occurred. Initial surgical reduction and fixation had been successful, when a second traumatic episode was encountered. This resulted in a further degree of posterior maxillary displacement, which was resistant to further surgical reduction. The resulting Class III malocclusion was treated using maxillary protraction headgear, in conjunction with removable orthodontic appliances and intermaxillary traction. Appliances were worn full time and inter-arch correction was achieved in six months. The resulting occlusion proved to be stable following the cessation of active treatment.
一名46岁的白人男性因外伤导致上颌后缩，在最初骨折发生八周后前来接受正畸治疗。最初的手术复位和固定很成功，但随后遭遇了第二次外伤事件。这导致上颌进一步向后移位，且无法通过进一步的手术复位。由此产生的III类错牙合畸形采用上颌前牵引矫治器，结合可摘正畸矫治器和颌间牵引进行治疗。矫治器全天佩戴，六个月内实现了牙弓间的矫正。在积极治疗结束后，最终的咬合关系被证明是稳定的。
