In a group of patients with mandibular deficiency with a low to normal mandibular plane angle (mean 20.7 degrees, range 10-28 degrees) and deep bite, the position of the condylar segment relative to the mandibular body, following bilateral sagittal split osteotomy (BSSO) for mandibular advancement was assessed. Ten patients in whom intermaxillary fixation (IMF) was used for a 5-week period were compared to 10 patients where 2 mm diameter Wurzburg positional screws were used as internal fixation. Six patients who were known bruxists and underwent BSSO were also reviewed. No clinically significant changes were seen in any patient group and no significant differences were found in the relationship with time between the condylar and body segments, irrespective of the fixation method used.
在一组下颌平面角低至正常(平均20.7度,范围10 - 28度)且有深覆合的下颌骨发育不全患者中,评估了双侧矢状劈开截骨术(BSSO)用于下颌前徙后髁突段相对于下颌体的位置。将使用颌间固定(IMF)5周的10例患者与使用直径2毫米的维尔茨堡定位螺钉作为内固定的10例患者进行比较。还对6例已知有磨牙症且接受了BSSO的患者进行了回顾。在任何患者组中均未观察到临床上的显著变化,并且无论使用何种固定方法,髁突段与下颌体段之间的关系随时间变化均未发现显著差异。
