Skeletal class III malocclusion is one of the most difficult dentofacial anomalies, characterized by deviation in the development of the mandible and maxilla in the sagittal plane, where the mandible is dominant in relation to the maxilla. In patients with class III malocclusion, anomalies in the dentoalveolar level and esthetic discrepancies are also frequent. The etiology of class III malocclusion is multifactorial due to the interaction of hereditary and environmental factors. Rehabilitation and treatment of malocclusion is one of the major goals of modern dentistry. This article presents the orthodontic-prosthetic therapy and rehabilitation of a 45-year-old patient with an abnormal occlusal vertical dimension and a skeletal class III malocclusion. The patient came to the clinic complaining about degraded esthetics and disordered functions of the orofacial region (functions of eating, swallowing, speech) and also pain in the temporomandibular joint. After the diagnosis was made, the patient was first referred to orthodontic treatment with fixed orthodontic appliances (self-ligating brackets system Rot 0.22). Upon completion of the orthodontic treatment, the patient was sent for further prosthetic treatment. Fixed prosthetic restorations were made in the upper and lower jaw, thus achieving a satisfactory result in terms of esthetics and function of the stomatognathic system.
骨性III类错牙合畸形是最复杂的牙颌面畸形之一,其特征是下颌骨和上颌骨在矢状面发育异常,下颌骨相对于上颌骨占主导地位。在III类错牙合畸形患者中,牙槽水平异常和美观差异也很常见。由于遗传和环境因素的相互作用,III类错牙合畸形的病因是多因素的。错牙合畸形的修复和治疗是现代牙科的主要目标之一。本文介绍了一名45岁患者的正畸-修复治疗及康复情况,该患者存在咬合垂直距离异常和骨性III类错牙合畸形。患者前来诊所就诊,主诉口面部区域美观受损、功能紊乱(进食、吞咽、言语功能)以及颞下颌关节疼痛。诊断明确后,患者首先接受了固定正畸矫治器(自锁托槽系统Rot 0.22)的正畸治疗。正畸治疗完成后,患者被送去进行进一步的修复治疗。在上颌和下颌制作了固定修复体,从而在口颌系统的美观和功能方面取得了满意的效果。
