Quality Control of Dental Bridges and Removable Prostheses Manufactured Using Phenix Systems Equipment

Currently, the mass parts production all over the world becomes more and more individual. It is required to be able to manufacture personalized complex shape parts with necessary microstructural, mechanical, thermo-physical, chemical and other properties in a quicker and a cheaper way. Selective Laser Sintering /Melting, a process of Additive manufacturing technologies, is applied to answer on this request. This paper discusses the manufacturing of dental fixed and removable prostheses directly from Co-Cr alloy powder using PHENIX SYSTEMS process. The quality control from the powder properties analyses up to the final laser sintered parts characterization has been performed. The applied Co-Cr alloy, developed by the company SINT-TECH, is CE certified and the physico-chemical properties of the sintered parts are matched to the dental standards NF IN ISO 22674 and NF IN ISO 9693.
