Restabelecimento das relações intermaxilares por meio de prótese total convencional

Abstract

The intermaxillary relations refer to the position of the mandible in relation to the maxilla in the vertical and horizontal planes, being the occlusion vertical dimension (OVD) and the centric relation (CR) essential in the treatment with complete dentures. This article reports a case of reestablishing intermaxillary relations with conventional complete dentures (CCD).A 82-year-old male patient sought care to replace his complete dentures due to dissatisfaction with the aesthetics and chewing function. After anamnesis and extra and intraoral exams, it was found that the current complete dentures showed large wear of the teeth, causing decreased OVD, aesthetic, and masticatory damage. The edges had satisfactory conditions for CCD rehabilitation. From the anatomical impressions of edges were obtained study models for making individual trays, later used for functional impression and obtaining the working models, on which were made wax plans. After adjustment of the upper wax plane and registration of the facial arch, the upper model was mounted on the semi-adjustable articulator. For the determination of the OVD, metric, physiological, aesthetic, and phonetic methods were used, and for the determination of CR, manipulation and physiological methods were used. The inferior model was assembled after determination of intermaxillary relations. Teeth were selected and mounted. In the aesthetic and functional testing of the teeth, occlusion, OVD, and esthetics were restored. The dentures were polymerized and installed. In proservations, the patient reported improvement in chewing, aesthetics, and phonetic. It was concluded that the reestablishment of intermaxillary relations contributed to aesthetic, masticatory, and phonetic rehabilitation.
