Qualitative analysis of 3D printed CoCr for metal- ceramic crowns and bridges

3D printed CoCr for metal-ceramic crowns and bridges have become a standard in prosthetic dentistry. Still, aesthetic and functional durability of metal-ceramic crowns and bridges with 3D printed metal-base in correlation to the production methods has not been extensively investigated, so it has been used without relevant data on material characteristics, nor evidence- based conclusions and clinical recommendations regarding the material. Production phases have significant influence on the final products’ characteristics. However, there is no standard for 3D printed metal production workflow, no input atomized powder control, and SLS machine settings are often left to the laboratory technician to master and optimize for their own benefit. This results in unstandardized final product with questionable mechanical characteristics and ceramic bonding strength. 3D printed CoCr metal- base for metal- ceramic crowns and bridges in form of test tubes and actual crowns and bridges will be analyzed for its precision, volume definition, build-up parameters, surface chemistry characteristics and mechanical characteristics.
