One of the most difficult types of malocclusion to cure is Class III malocclusion. Maxillary protraction is a common component of orthodontic/surgical treatments for Class III individuals since maxillary retrognathia is the primary factor contributing to their condition. A Vietnamese girl of 16 years old presented with severe symptoms of anterior crossbite and Class III malocclusion of the skeletal and dental structures. Among the dental characteristics were a prognathic mandible, retrognathic maxilla, and proclined lower incisors. The medical history revealed no abnormalities. Since the patient refused to undergo orthognathic surgery, we suggested using multiloop edgewise archwire (MEAW), which combines temporary anchorage devices (TADs) with modified Class III elastics for camouflage treatment of Class III malocclusion. This case illustrated the use of TADs. MEAW combines TADs with modified Class III elastics for camouflage therapy. It is a potentially effective treatment option for adolescents diagnosed with Class III skeletal malocclusion.
最难矫治的错牙合畸形类型之一是Ⅲ类错牙合畸形。上颌前牵引是Ⅲ类患者正畸/外科治疗的常见组成部分,因为上颌后缩是导致其病情的主要因素。一名16岁的越南女孩表现出严重的前牙反牙合症状以及骨骼和牙齿结构的Ⅲ类错牙合畸形。牙齿特征包括下颌前突、上颌后缩和下前牙前倾。病史显示无异常。由于患者拒绝接受正颌手术,我们建议使用多曲方丝弓(MEAW),它将临时支抗装置(TADs)与改良的Ⅲ类弹力牵引相结合,用于Ⅲ类错牙合畸形的掩饰性治疗。本病例展示了TADs的应用。MEAW将TADs与改良的Ⅲ类弹力牵引相结合用于掩饰性治疗。对于诊断为Ⅲ类骨骼错牙合畸形的青少年来说,这是一种潜在有效的治疗选择。
