目的探讨上颌快速扩弓矫治恒牙早期后牙反合及下颌偏斜的特点及临床处理。方法回顾性分析8例上颌快速扩弓矫治患者临床资料,予以上颌快速扩弓矫治,对比矫治前后头颅定位后前位片(P-A)测量分析结果。结果全组患者矫治后各标志点与正中矢状定位线的水平距离均较矫治前有显著改善(P<0.05)。全组患者矫治后S3面积相比矫治前有显著变化(P<0.05)。全组患者上颌快速扩弓矫治过程均未见明显不适和不良反应。结论对于常见的恒牙早期后牙反合及相关性下颌偏斜,可规范予以上颌快速扩弓矫治扩大上颌牙弓、纠正下颌骨不对称部分,消除患者不适、改善生活质量。
Objective To investigate the characteristics and clinical treatment of maxillary rapid expansion after correction of primary posterior teeth anti-syndesmosis and mandibular deviation. Methods The clinical data of 8 patients with maxillary rapid expansion were retrospectively analyzed. The maxillary maxillary expansion was performed. The results of P-A measurement before and after cranioplasty were compared. Results The horizontal distances between each marked point and median sagittal alignment line in all patients were significantly improved after treatment (P <0.05). There was a significant change in S3 area after treatment in all patients (P <0.05). No significant discomfort and adverse reactions were observed in the whole process of rapid maxillary expansion in maxillary patients. CONCLUSIONS: For the common anterior teeth posterior incontinence and related mandibular deviation of the common permanent teeth, maxillary maxillary dental arch can be expanded to correct maxillary mandibular asymmetry, eliminate discomfort and improve quality of life.
