Young females with retruded and hyperdivergent mandibles, class II openbite malocclusions, and steep occlusal planes with or without TMJ symptoms are at higher risk for Idiopathic Condylar Resorption (ICR). Such patients undergoing orthodontic and /or surgical treatment should be informed of possible relapse due to ICR. Orthognathic Surgery with Total joint replacement or Orthognathic surgery alone may both be acceptable options for management of the facial deformity and the malocclusion that ensues from ICR. Proper patient selection is key to achieving a successful outcome. Current trends and the evidence in the literature suggest that orthognathic surgery with alloplastic joint replacement may be the preferred approach.
下颌后缩且垂直向生长过度的年轻女性，伴有安氏II类开颌错牙合以及陡峭的牙合平面，无论有无颞下颌关节症状，都有更高的特发性髁突吸收（ICR）风险。接受正畸和/或外科治疗的此类患者应被告知因ICR可能出现的复发情况。正颌手术联合全关节置换或单纯正颌手术都可能是治疗ICR导致的面部畸形和错牙合的可接受选择。正确选择患者是取得成功治疗效果的关键。目前的趋势和文献证据表明，正颌手术联合异体关节置换可能是首选方法。
