摘要/Abstract

摘要： 本病例系统性介绍了1例于外院治疗失败的青春后期伴有上颌骨横向发育不足的骨性Ⅲ类错牙合患者的诊治经历。本病例采用了种植钉辅助的上颌骨扩弓联合直丝弓矫治器的矫治策略,通过两周的种植钉辅助上颌骨扩弓,使患者面中部的横向及前后向发育不足得到显著改善,然后通过直丝弓矫治器进一步纠正了患者的牙性问题,最终达到了健康、美观、稳定的矫治效果。

Abstract: This case report systematically describes the diagnosis and treatment of a late-adolescent patient with skeletal Class Ⅲ malocclusion and maxillary transverse deficiency who had previously experienced unsuccessful treatment at another institution. Following a comprehensive evaluation of the patient's dentofacial condition, a treatment strategy combining miniscrew-assisted maxillary expansion with a preadjusted edgewise appliance was adopted. After two weeks of miniscrew-assisted maxillary expansion, both the transverse and anteroposterior deficiencies of the midface were markedly improved. Subsequent treatment with a preadjusted edgewise appliance further corrected the dental discrepancies, ultimately achieving a treatment outcome characterized by satisfactory function, health, esthetics, and stability.

Key words: Angle class Ⅲ malocclusion, skeletal class Ⅲ malocclusion, miniscrew-assisted rapid maxillary expansion
