TESTS METALLIC BIOMATERIALS FOR COMPUTER-AIDED DESIGN AND MANUFACTURING OF FIXED PROSTHETIC RESTORATIONS

Abstract

A direct metal laser sintering method (DMLS) is a new technology used for getting structures by the CAD/CAM procedures. The aim of the elaboration was a question of structural identification and setting strength parameters of titanium (Ticp) and its alloy (Ti6Al4V) which are used to serve as base for those permanent prosthetic supplements which are later manufactured with the employment of CAD/CAM systems. The research work was performed on Ticp samples – those which were intended for manufacture of structures by decrement milling working, and Ti6Al4V samples that comes from laser increment sintering of powder. According to the results obtained, the following conclusion has been derived: when strength aspect is discussed, the DMLS method is a preferred one for manufacturing of load structures in dentistry and may be an alternate way for the CAD/CAM system used in decrement processing.
