目的探讨不对称拔牙矫治的临床治疗要点。方法 22例采用不对称拔牙的病例,12例患者存在下颌第一磨牙严重龋坏;6例患者存在上颌侧切牙严重龋坏或先天缺失;4例患者同时存在下颌第一磨牙和上颌侧切牙严重龋坏。均采用直丝弓矫治技术。结果矫治疗程18~32个月,平均22个月。矫治后患者均达到牙齿排列整齐、前牙覆牙合覆盖正常、后牙尖窝交错的咬合关系,软组织侧貌得到一定程度的改善。结论不对称拔牙矫治在支抗控制合理的情况下能够取得满意的效果。
Objective To explore the clinical treatment of asymptomatic tooth extraction. Methods Twenty-two patients had asymmetric tooth extraction, 12 patients had severe decay of mandibular first molars, 6 patients had severe caries or congenital absence of maxillary incisors, 4 patients had severe mandibular first molars and maxillary lateral incisors Carious. Straight wire arch correction techniques are used. Results of treatment 18 to 32 months, an average of 22 months. After treatment, all the patients reached the orderly arrangement of the teeth, the anterior crossbite coverage was normal, the posterior teeth spine interlaced occlusion relationship, soft tissue profile improved to some extent.
