Abstract

The aim of this article is to report a case series of a miniscrew-anchored maxillary protraction therapy (MAMP). Two male patients presenting with Class III malocclusion were included in this report. The treatment consisted of a hybrid expander and two miniscrews at the anterior region of the mandible anchoring Class III elastics for maxillary protraction. Effective maxillary length, ANB angle and Wits appraisal increased after treatment. Slight dental effects were observed. MAMP therapy produced substantial skeletal effects and might be a good treatment option for Class III growing patients.

摘要

本文旨在报告一组微型螺钉锚定上颌前牵引治疗(MAMP)的病例。本报告纳入了两名患有III类错牙合畸形的男性患者。治疗包括一个混合扩弓器和在下颌前部区域的两颗微型螺钉,用于锚定III类弹性牵引装置以进行上颌前牵引。治疗后有效上颌长度、ANB角和Wits评估值增加。观察到轻微的牙齿效应。MAMP治疗产生了显著的骨骼效应,可能是III类生长发育期患者的一种良好治疗选择。
