【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。更多还原

【Abstract】 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.更多还原
