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.

Tooth wear is attributed to several factors many of which often remain unidentified. Management of tooth wear is challenging in preventive and restorative dentistry. Correct assessment of occlusal vertical dimension, interocclusal rest space, and centric relation records are critical for successful treatment. In order to evaluate different treatment modalities and select the treatment of choice some information can be obtained from study casts and diagnostic wax-up. In order to achieve a predictable and desirable result, a systematic approach may be helpful. This paper describes the full mouth rehabilitation of a 36-year-old bruxer with severely worn dentition and other dental problems such as unfavorable restorations. A diagnostic work-up was performed and provisional restorations were made; then, they were clinically evaluated and adjusted based on the criteria dictating esthetics, phonetics, and vertical dimension. After endodontic therapy, clinical crown lengthening was performed. Two short implants were inserted in the posterior mandible. Custom-cast dowel cores and metal-ceramic restorations were fabricated and a full occlusal splint was used to protect the restorations. We ensured stable contacts on all teeth with equal intensity in centric relation and anterior guidance in accord with functional jaw movements.

This review argues that (1) the habitual mandibular position is constantly variable and so cannot be considered as a craniomandibular reference point, (2) there is no unique centric relation, (3) mandibular posture greatly depends on head posture, (4) clinical evaluation of the occlusal vertical dimension is mostly empirical, and (5) neither the vertical dimension at rest nor the centric relation can be determined by means of existing instrument-based clinical methods. However, some physiological conditions exist that facilitate the recording of craniomandibular position.
