The treatment of open bite malocclusion is generally considered a challenge due to its multifactorial etiology. Many treatment modalities to correct open bites, including orthognathic surgery and dental compensation, have been proposed. Dental compensation (intruding the posterior teeth and uprighting and extruding the anterior teeth with elastics) is a treatment option for borderline patients and those who are reluctant to undergo surgery. This report documents the treatment of a patient with a severe skeletal open bite malocclusion whose treatment plan originally included fixed appliance therapy as well as orthognathic surgery. He was subsequently treated with only fixed appliances. The patient, a male 17 years, 7 months of age, presented with a Class II, Division 1 malocclusion, 5 mm anterior open bite, and an increased anterior facial height. He was treated with extraction of the maxillary and mandibular premolars, full fixed appliances, and anterior vertical elastics. After 30 months of active treatment, a Class I occlusion with improved overjet and overbite was achieved.
由于开（牙合）错（牙合）畸形的病因多因素，其治疗通常被认为具有挑战性。已经提出了许多矫正开（牙合）的治疗方法，包括正颌外科手术和牙齿代偿。牙齿代偿（压低后牙并用弹力牵引直立和伸长前牙）是临界病例以及那些不愿接受手术的患者的一种治疗选择。本报告记录了一名患有严重骨骼性开（牙合）错（牙合）畸形患者的治疗情况，其治疗计划最初包括固定矫治器治疗以及正颌外科手术。随后他仅接受了固定矫治器治疗。该患者为17岁7个月男性，表现为安氏II类1分类错（牙合）、前牙开（牙合）5mm以及面下1/3高度增加。他接受了上颌和下颌前磨牙拔除、全口固定矫治器以及前牙垂直弹力牵引治疗。经过30个月的积极治疗，实现了覆盖和覆（牙合）改善的安氏I类咬合关系。
