The goal of early treatment of Class III malocclusion isfocused on providing a more favourable environment for normal growth and on improving the psychosocial development of the child by improving the facial appearance. Rapid palatal expansion with maxillary protraction and face mask has provided a predictable and effective approach to managing the treatment. We are presenting a case report of a growing Class III treated using maxillary protraction therapy, (Rapid maxillary expansion using bonded RME appliance, to loosen the nasomaxillary sutures and Petit face mask with bonded occlusal splint to unlock the maxilla). With early intervention, patient compliance is much better, most of them achieving overcorrection in less than a year. Close monitoring and follow up was done for 5 years to ensure stability of the treatment, and there was no relapse tendency.
Ⅲ类错颌早期治疗的目标集中在为正常生长提供更有利的环境，并通过改善面部外观来促进儿童的心理社会发展。使用上颌前牵引和面罩进行快速腭扩展为治疗提供了一种可预测且有效的方法。我们现报告一例采用上颌前牵引疗法治疗的生长发育期Ⅲ类错颌病例（使用带环式快速扩弓矫治器进行快速上颌扩展，以松解鼻上颌缝，并使用带环式咬合板的Petit面罩来使上颌解锁）。通过早期干预，患者的依从性要好得多，大多数患者在不到一年的时间内实现了过度矫正。进行了5年的密切监测和随访以确保治疗效果的稳定性，且没有复发倾向。
