Abstract

Inappropriate prostheses in the oral cavity of aged or middle-aged patients with untreated dentofacial deformity are often seen. Currently, the condition of such patients has been improved, and they are reviewed regularly, supporting evidence that the occlusions and aesthetic conditions are maintained as stable. This report describes the case of a 48-years-old woman with mandibular protrusion, facial asymmetry, missing teeth and an unfitted prosthesis. The treatment objectives were to establish a Class I molar relationship, and to obtain proper interdigitation and an ideal overbite and overjet. Orthodontic treatment involved the extraction of the lower right lateral incisor, the use of an edgewise appliance and orthognathic surgery. Occlusal function and facial balance were improved by treatment with a comprehensive approach involving orthodontic, crown restoration, and periodontal management. Post-treatment records after 2 years showed good results with stable occlusion. However, it is also important to note the observation of stable occlusion.
