Importance of dental occlusion in rehabilitation by fixed partial prosthesis

DENTAL OCCLUSION, DENTURE, PARTIAL, REHABILITATIONAbstract
Dental occlusion has always been the focus of attention for all branches of Stomatology. On rehabilitating a patient, it is necessary to know his masticatory function and to try to reproduce the dental contacts once the prosthetic appliances have been installed. A study on occlusion was conducted that relates this aspect to the rehabilitation by fixed partial denture using fixed rigid bridges of ceramic and metal. A group of 20 patients was selected to undergo a previous occlusal study. The models were mounted in the semiadjustable articulator by intraoral registries, using the clinical techniques of transportation by means of the facial arch. The models were waxed by the codified dripping technique, the contacts were verified in the metallic substrcuture test and later in the ceramic test and during the installation. In 80 % of the cases the same points of contact existing at the beginning were obtained. Mild occlusal adjustments were made in the other 20 %, due to characteristic factors of this rehabilitating work. The benefits of the semiadjustable articulator and the transfer by the facial arch in the mounting of the models to attain a correct reestablishment of the occlusal morphology were proved in order to maintain the masticatory pattern of the patient or to get as close as possible to his occlusal template.Downloads
