BACKGROUND
The present case report describes the orthodontic treatment and long-term follow-up of an adult female patient (27 years) who was diagnosed with a mild Class III malocclusion characterised by an anterior and lateral open bite and three periodontally-compromised first permanent molars.
AIM
The aim of treatment was to provide an acceptable aesthetic and functional occlusion while, at the same time, improving the periodontal prognosis.
METHODS
The patient was treated with fixed orthodontic appliances utilising direct and indirect skeletal anchorage derived from two mini-screws placed in the palate and one mandibular buccal mini-screw.
RESULTS
The objectives of good aesthetics, a functional occlusion, a healthy periodontium and a balanced profile were achieved. The total treatment time was 31 months, which comprised 13 months of maxillary fixed labial appliances and 25 months of mandibular fixed labial appliances. The three-year follow-up records showed stability of the Class ILL correction.
背景
本病例报告描述了一名成年女性患者（27岁）的正畸治疗及长期随访情况，该患者被诊断为轻度III类错牙合，其特征为前牙及侧方开牙合，且三颗第一恒磨牙存在牙周问题。
目的
治疗目的是提供可接受的美观和功能咬合，同时改善牙周预后。
方法
患者采用固定正畸矫治器进行治疗，利用置于腭部的两枚微型螺钉和一枚下颌颊侧微型螺钉获得直接和间接的骨支抗。
结果
实现了美观良好、功能咬合、牙周健康和面部轮廓协调的目标。总治疗时间为31个月，其中上颌固定唇侧矫治器治疗13个月，下颌固定唇侧矫治器治疗25个月。三年随访记录显示III类错牙合矫治效果稳定。
