Introduction. The researches in dental materials aria improve the mechanical and biological properties of the veneered prosthetic constructions. The veneered bridges combine the strength of the metallic restorations with cosmetic effect of the ceramic or polymeric component. Materials and methods. The aim of our study is to compare the mechanical and technological parameters of three aesthetic materials: Solidex (Shofu) and SR Adoro (Ivoclar) resins and Vintage Halo (Shofu) ceramic. The research investigate the characteristics in making the design of the metall frame, the specific conditioning of the bonding surface and the methods in application of the aesthetic component, varying with the nature of the material. Results and discussions. The knowledge of the technological procedures achieves higher mechanical performance of fixed veneered constructions. The analyse of those three materials demonstrate that ceramic component has a greater resistance. Making a comparison between the two types of composites, the SR Adoro resin has higher mechanical performance, because the double cure method determine a compact and homogenous structure, consequently, superior performance. Conclusions. The knowledge of the characteristics of the technological steps allowed to choose an adequate aesthetic material for fixed veneered bridges, with best mechanical resistance and higher longevity.
