The Influence of Technology on the Physicochemical and Electrochemical Properties of the Prosthetic Materials

Direct Metal Laser Sintering (DMLS) is a new technology used for getting e.g. prosthetic restorations by CAD/CAM procedure. The aim of work was finding an answer to question if, or the whether at all, type of manufacturing technology affect on the physicochemical and electrochemical properties of the finished product? The work presents the results of the studies of two Co-Cr alloys, from which the samples were obtained in conventional casting and DMLS technology. Based on obtained results it was found, that the DMLS method is a preferred one for manufacturing of prosthetic devices and is an alternative way for standard casting technology. Use of the three dimensional printing process compared to casting procedure reduces the time of prosthetic restorations manufacturing and improve dimensional accuracy.
