上颌异位尖牙埋伏阻生的辅弓矫治

The treatment of canine ectopic eruption with the auxiliary arch fragment

目的:探讨垂直曲式的片段辅弓应用在尖牙异位萌出的固定矫治方法。方法:对6例上颌异位尖牙用垂直曲式的片段辅弓支持下,固定正畸技术进行矫治。结果:6例在片段辅弓固定矫治器支持下,12个月左右异位尖牙进入牙弓排齐。结论:上颌异位尖牙通过正畸技术完全能排入正常牙列,不需拔除。

Objective To explore the treatment method of the vertical loop of auxiliary arch fragment in canine ectopic eruption with fixed orthodontic technique.Methods In 6 cases of ectopic maxillary canine a fixed orthodontic technique is used with the vertical loop of auxiliary arch fragment support.Results 6 cases of ectopic canine with the vertical loop of auxiliary arch fragment support have been aligned into the dental arch in about 12 months.Conclusion The ectopic canine can be aligned completely into the dental arch by means of the orthodontic technique without the tooth extraction.
