摘要
目的:探讨多种方法相结合,对双侧下颌第二磨牙低位阻生伴上颌磨牙伸长患者的正畸治疗效果。方法:采用自制树脂球配合弹力线牵引、微种植支抗钉、压低辅弓等技术对其进行了矫治。结果:经过33个月的治疗,患者双侧的下颌第二磨牙牵引到位,上颌伸长磨牙也成功压低,均实现了良好的咬合和邻接关系。结论:对下颌第二磨牙低位埋伏阻生伴上颌磨牙伸长的的患者,采用树脂球配合弹力线牵引,结合微种植支抗钉、压低辅弓等技术,简洁高效地完成矫正,效果确切。
Objective:To explore the orthodontic treatment effect for patient with bilateral impacted mandibular second molars and elongated maxillary molars.Methods:The treatment involved the use of resin ball with elastic wire traction,micro-implant anchorage,and intrusion arch.Results:After 33 months of treatment,bilateral mandibular second molars were successfully pulled in place and the elongated maxillary molars were effectively depressed,achieving good occlusal and proximal relationship.Conclusion:For patient with low-impacted mandibular second molars and elongated maxillary molars,the combination of resin ball with elastic wire traction,micro-implant anchorage,and intrusion arch can achieve simple and efficient correction.
