目的介绍通过消除单侧干扰,并建立生理性诱导矫治功能性下颌偏斜的方法。方法选取2011年~2014年我院收治的功能性下颌偏斜患者11例。矫治过程中先排齐整平上下牙弓,解除个别牙反,上牙弓狭窄的患者配合扩弓治疗。通过后牙粘接垫暂时消除导致下颌功能性偏颌的干扰,同时利用多曲唇弓调整左右平面,压低并唇倾上颌干扰牙,对侧则建立生理性诱导。结果所有患者功能性偏颌改善明显,正中位下颌前牙中线与面中线一致,软组织颏点与面中线接近一致,双侧磨牙关系恢复中性,正中关系位咬重建时间为2~11个月,平均时间6.7个月。结论消除单侧干扰是纠正功能性下颌偏斜行之有效的手段。
Objective To introduce a method of correcting functional mandibular deviation by eliminating unilateral interference and establishing physiological induction. Methods Eleven patients with functional mandibular deviation admitted from 2011 to 2014 in our hospital were selected. Alignment process first align and level up and down the dental arch, lift the individual teeth anti , the upper arch of the stenosis patients with expansion arch treatment. Through the posterior teeth adhesive pad to temporarily eliminate the mandibular functional jaw caused by the interference, while the use of multiple curved lips to adjust the left and right plane, down and lip tilt maxillary interference teeth, the contralateral is to establish physiological induced. Results All patients’ functional partial jaw improved obviously. The median line of mandibular anterior teeth coincided with the midline of midline, the soft tissue’s chin point was close to the median line, the bilateral molar relationship recovered to neutrality, and the middle relationship bit was rebuilt from 2 to 11 Months, the average time of 6.7 months. Conclusion Elimination of unilateral disturbance is an effective means to correct functional mandibular deviation.
