Abstract

Malocclusions with anterior crossbite are a major esthetic and functional concern for patients. This case report presents a 27-year-old Syrian female who was diagnosed with a class 3 malocclusion, combined with anterior crossbite, deep bite, concave profile, and inadequate maxillary incisor exposure. There was a centric occlusion (CO)/centric relation (CR) discrepancy and the mandible could be manipulated to near edge-to-edge incisal relation. Correction was done by class 3 intermaxillary elastics on upper and lower mini-implants for the first 6 months, followed by preadjusted edgewise appliance. The objective of implant-supported elastics was to adapt the patient for the CR condylar position without dental effect. Treatment was completed in 24 months with satisfactory dental and facial relationship.

摘要

前牙反合错牙合是患者主要的美观和功能问题。本病例报告介绍了一名27岁的叙利亚女性,她被诊断为III类错牙合,合并前牙反合、深覆牙合、凹面型和上颌切牙暴露不足。存在正中牙合(CO)/正中关系(CR)差异,下颌可被操纵至近乎切缘对切缘的关系。最初6个月通过在上、下颌微型种植体上使用III类颌间弹力牵引进行矫治,随后使用预成方丝弓矫治器。种植体支持的弹力牵引的目的是使患者适应CR髁突位置而不产生牙齿效应。治疗在24个月内完成,牙齿和面部关系令人满意。
