Abstract
CoCr alloys are traditionally manufactured by casting, but nowadays alternatives such as CAD/CAM milling or 3D Printing Technologies (Direct metal laser sintering (DMLS), Selective laser sintering (SLS), Selective laser melting (SLM), Electron beam melting (EBM)) are available. CoCr blanks to be milled in the green body state (unsintered metal powder held together by a binder) and then densely sintered try to overcome the hardness of the alloy and to ease the milling process.The aim of this paper is to compare the quality of prosthetic pieces manufactured by CAD/CAM milling, CAD/CAM sintering and Selective laser sintering.Because the chemical composition of the CoCr alloys used is comparable, differences in quality of the prosthetic pieces are the result of the manufacturing technology. In terms of structure and corrosion resistance, the CAD/CAM milling sample proved to be the best choice and the SLS sample the worst.
