Because of their multifactorial etiologies, dental and skeletal open bites are among the most difficult malocclusions to treat to a successful and stable result. Etiologic factors include vertical maxillary excess, skeletal pattern, abnormalities in dental eruption, and tongue-thrust problems. The purpose of this article was to report the treatment of an adult patient with a lateral open bite and a unilateral posterior crossbite. The treatment involved nonextraction therapy, including intermaxillary elastics, to obtain dentoalveolar extrusion in the region of the lateral open bite. The treatment results were successful and remained stable 2 years later.
由于其多因素病因，牙性和骨性开𬌗是最难治疗的错𬌗之一，难以达到成功和稳定的结果。病因因素包括上颌垂直过度、骨骼形态、牙齿萌出异常和舌前伸问题。本文旨在报告一例成人患者的治疗情况，该患者存在侧方开𬌗和单侧后牙反𬌗。治疗包括非拔牙治疗，如𬌗间橡皮圈，以获得侧方开𬌗区域的牙𬌗牙槽骨向外挤压。治疗效果成功且 2 年后仍保持稳定。
