Abstract

Provisional prosthetics in the rehabilitation algorithm with fixed restorations has a number of particularly important roles in transmitting the data absolutely necessary to the dental laboratory for the achievement of the definitive work, which influences the healing of periodontal tissues and, definitively, the occlusal scheme and the resizing of the vertical occlusal dimension. The aim of this study is to analyze the factors involved in the choice of provisional prosthesis and the implications this has for the definitive prosthesis according to the particularities of each individual case. Material and methods: A total of 86 patients diagnosed with partially reduced edentulousness, i.e., coronal recessed dental lesions, were included in the study group and clinically and paraclinically evaluated for prosthetic rehabilitation by different types of definitive restorations from the current prosthodontic range, prefaced within the therapeutic algorithm of provisional restorations. Results: The current clinical-technological algorithm of rehabilitation with fixed restorations, provisional prosthetics represents an extremely important step in order to conform the periodontal tissue on the one hand, to protect the prepared substructures on the other hand, and last but not least to prefigure the shape of the future prosthetic rehabilitation in the context of dento-somatic-facial harmony. Conclusions: Prosthetic restorations made by the digital technique are extremely precise, their design is laborious considering all biomechanical aesthetic criteria so that we have individualized restorations that lead to successful final prosthetics.
