传统上采用下颌上颌联合截骨术矫正下颌偏颌和上颌咬合平面倾斜。本病例报告描述了用微支具代替上颌截骨治疗后的功能和形态学变化。1例男孩，16岁5个月，有颞下颌关节疾病症状，面部不对称伴下颌偏斜，上颌咬合平面倾斜。右侧上颌磨牙比左侧上颌磨牙突出3mm。此外，还存在功能性问题：咀嚼不平衡和双侧髁运动范围不对称。上颌右磨牙微支抗侵入矫治上颌斜颌平面后，下颌骨截骨矫治下颌骨偏斜。治疗结果显示，除形态学改变对称外，还实现了功能对称，提示微支具联合下颌截骨治疗下颌骨偏曲、上颌牙合平面倾斜的患者是有效的。[J]口腔正畸矫形学杂志2009；36:868-77 .]
Conventionally, the combination of mandibular and maxillary osteotomy is used to correct both mandibular deviation and maxillary canted occlusal plane. This case report describes functional and morphologic changes after an alternative treatment with miniscrew anchorage instead of maxillary osteotomy. A boy, aged 16 years 5 months, had temporomandibular joint disease symptoms, facial asymmetry with mandibular deviation, and a maxillary canted occlusal plane. The maxillary molars on the right side were extruded 3 mm compared with those on the left side. In addition, there were functional problems: lopsided chewing and asymmetric motion range of the bilateral condyles. After correction of the maxillary canted occlusal plane by intrusion of the maxillary right molars with miniscrew anchorage, the mandibular deviation was corrected with mandibular osteotomy. As the therapeutic result, functional symmetry was achieved in addition to symmetric morphologic changes, suggesting that combination treatment of miniscrew anchorage and mandibular osteotomy is effective for treating patients with mandibular deviation and maxillary canted occlusal plane.
