Abstract

This case report illustrates the treatment of a 17-year-old male patient characterized by an anterior open bite, skeletal Class III malocclusion, mandibular deviation, and severe temporomandibular joint symptoms. Given the complexity of the patient's condition, a strategic treatment approach was employed. Stabilization splint was used initially for a duration of 9 months to alleviate TMJ symptoms and repositioning the condyle. Through model analysis on the articulator pretreatment, we found a worsening of his V-shape open bite due to occlusal interference in molars. The patient refused the surgery, so the multiloop edgewise archwire treatment was provided to upright the molars and eliminate occlusal interference. After 26 months of treatment, a functional and aesthetic occlusion, and a relatively well-balanced facial profile were established. After a 6 years post-treatment follow-up, the results of this case have demonstrated long-term stability.

稳定夹板联合多环侧弓丝治疗骨性III类开咬错伴颞下颌紊乱：6年随访1例

本病例报告描述了一名17岁男性患者的治疗，其特征是前牙开咬，骨骼III类错颌，下颌偏颌和严重的颞下颌关节症状。考虑到患者病情的复杂性，我们采用了一种有策略的治疗方法。最初使用稳定夹板9个月以缓解TMJ症状并复位髁突。通过对关节器预处理的模型分析，我们发现由于磨牙咬合干扰导致他的v型开咬恶化。患者拒绝手术，因此给予多环侧弓丝治疗，使磨牙直立，消除咬合干扰。经过26个月的治疗，建立了功能性和美观的咬合，以及相对平衡的面部轮廓。经过6年的治疗后随访，该病例的结果显示长期稳定。
