CRISTINA KREMS, COSMIN SINESCU, PAUL CORNEL FREIMAN, ANDREEA-CODRUTA COJOCARIU, MEDA LAVINIA NEGRUTIU, CODRUTA ANGELA PODARIU EVALUATION OF MARGINAL ADAPTATION OF FIX PARTIAL PROSTHESIS TO POLYMERIC ABUTMENTS The present study evaluates the marginal adaptation of fixed partial prosthesis made from resin composite. The main goal is to obtain restorations with excellent aesthetics and extremely high quality which increase the lifetime of the prosthesis system - dental structures. The method allowed the observation of defects that might occur during the technological processing, as well as their correction. It was used the 3D Shape software with which have been achieved scans for the virtual presentation the marginal adaptation. Following the investigation it was showed, that the cementation is extremely important, the errors occurring in this phase are influencing of the final results and behaviour. Composite resin fixed partial prosthesis are restorations which through a correct technology can compete with the ceramic fixed partial dentures.
