OBJECTIVE
The objective of the present study was to evaluate the jaw function and anatomical changes subsequent to orthodontic treatment combined with mandibular advancement or set-back surgery.
STUDY DESIGN
The sample consisted of 67 combined skeletal and dental malocclusion patients, who had received orthodontic and surgical treatment previously. Three and 6 months following jaw surgery, the following jaw functions were evaluated: the level of occlusal force developed, the efficiency of masticatory function, the size in the temporomandibular joint (TMJ), the relationship between occlusal force and maxillo-mandibular skeletal change, and the range of mandibular movement.
RESULTS
The results revealed that after surgery the occlusal force, masticatory function, TMJ positioning, and mandibular movement distance were all different from presurgery values. The surgical set-back group jaw function recovery proved to be more rapid than that for the mandibular-advancement group.
CONCLUSION
Surgical mandibular advancement and set-back by sagittal-split osteotomy influence subsequent mandibular function.
目的
本研究的目的是评估正畸治疗联合下颌前徙或后退手术之后的颌功能及解剖学变化。
研究设计
样本包括67例曾接受正畸和外科治疗的骨骼与牙性错合联合患者。颌骨手术3个月和6个月后，评估以下颌功能：产生的咬合力水平、咀嚼功能效率、颞下颌关节（TMJ）大小、咬合力与上颌-下颌骨骼变化之间的关系以及下颌运动范围。
结果
结果显示，术后咬合力、咀嚼功能、TMJ定位和下颌运动距离均与术前值不同。手术后退组的颌功能恢复被证明比下颌前徙组更快。
结论
矢状劈开截骨术进行的手术下颌前徙和后退会影响后续的下颌功能。
