Preparos dentais com finalidade protética: uma revisão da literatura

Considering the importance of fixed partial denture, removable partial denture and hybrid prosthesis, the main objective of this work is to realize a literature review about tooth preparation with prosthetic purpose. The prosthetic dental preparation is one of the critical factors that must be carefully planned and executed, to allow a longevity treatment. This must reestablish the phonetic and masticatory functions, phonetic and masticatory, function, beyond esthetics, and these requisites are basic for the patient’s satisfaction with the final rehabilitation results. In PPD the quantity of wearing in the prepared dental walls, angulation and the margin location, influence the final restoration esthetics and longevity. The dental preparation, in this kind of prosthesis, must allow an adequate restoring material thickness, at the same time that the pulpal and periodontal integrity must be preserved. In the RPD the dental preparation of adequate guiding planes, occlusal rests and tooth contours become extremely necessary for the rehabilitation success in this kind of prosthesis, which present the objective to preserve the oral health, comfort and function for the patient. The root height reduction in hybrid prosthesis is important because it can diminishes possible risks of mobility and consequent loss of the dental element, because, the preservation of these roots prevents bone loss, improving the prosthesis retention and stability. Observing the papers revised here, it is concluded that tooth preparation is an important factor in the oral rehabilitation success. descriptors: Tooth preparation • Dental prosthesis. ***** Doutoranda na área de Prótese Parcial Removível do Departamento de Prótese da Faculdade de Odontologia da Universidade de São Paulo – (USP).
