Rigid fixation of facial osteotomies has had a significant effect on reducing morbidity in these patients. Any osteotomy in a patient with erupted permanent dentition previously fixed with wires and intermaxillary fixation can now be managed by metal plates and screws, eliminating or decreasing the need for the jaws to be held together. The problems of palpable plates and screws and malposition of jaws have been eliminated by precise techniques. The cost of plates and screws and the increased time needed for their application have been offset by decreased hospitalization time and fewer complications. A new microsystem with screws 0.8 mm in diameter and plates 0.5 mm in thickness has further expanded the fields for application, particularly in children and infants.
面部截骨术的坚固内固定对降低这些患者的发病率产生了显著效果。对于之前采用钢丝和颌间固定的恒牙已萌出患者的任何截骨术,现在都可用金属板和螺钉进行处理,从而消除或减少了颌骨固定在一起的需求。精确的技术消除了可触及的金属板和螺钉以及颌骨错位的问题。金属板和螺钉的成本以及应用所需增加的时间已因住院时间缩短和并发症减少而得到弥补。一种新型微系统,其螺钉直径为0.8毫米,金属板厚度为0.5毫米,进一步扩大了应用领域,尤其适用于儿童和婴儿。
