Orthodontists often have trouble treating patients who have temporomandibular joint disorders because occlusion changes depend on the position of unstable condyles. This characteristic means the patients do not have definite criteria with which to make an accurate orthodontic diagnosis, so clinicians are unable to establish a reliable treatment plan. This article reports on the treatment of a patient with skeletal Class II relationship and condylar resorption. A stabilization splint was used before any active orthodontic tooth movement to stabilize her condylar position. Although the patient exhibited dramatically increased open bite and a retruded mandibular position after splint therapy, her occlusion and facial esthetics were resolved by orthodontic camouflage treatment with appropriate orthodontic mechanics after extraction of 4 premolars.
正畸医师在治疗颞下颌关节紊乱的患者时往往会遇到困难,因为咬合的改变取决于不稳定髁突的位置。这一特征意味着患者没有明确的标准来进行准确的正畸诊断,因此临床医生无法制定可靠的治疗计划。本文报告了一例骨性Ⅱ类错颌伴髁突吸收患者的治疗。在进行任何主动的正畸牙齿移动之前,使用稳定夹板来稳定患者的髁突位置。尽管患者在夹板治疗后出现了明显的开颌和下颌后缩,但通过 4 颗前磨牙的拔除,使用适当的正畸力学进行正畸掩饰治疗,解决了她的咬合和面部美观问题。
