Class III dental treatment with invisible aligners in a mutilated patient

Abstract

The purpose of this study is to present a clinical case of preparation for rehabilitation in a patient with severe overbite and bruxism, treated with invisible aligners. The patient R.F.F., male, 56 years old, sought assistance at the IPEO School Clinic reporting issues of tooth wear and spaces between them. In the functional analysis, the patient exhibited adapted swallowing with tongue interposition between the incisors, a history of pacifier uses in childhood, and different CR from MIH. The malocclusion classification was Class III, left subdivision, of dento-skeletal and postural nature. The treatment consisted of removing occlusal interferences; closing diastemas by lower retraction, improving the overjet; and creating space for future prosthetic rehabilitation. At the end of orthodontic treatment, it could be observed that the main proposed objectives were achieved, making the rehabilitative treatment less complex and more conservative.
