Improvement of Processability Characteristics of Porcelain-Based Formulations Toward the Utilization of 3D Printing Technology.

A study of the feasibility of porcelain-based formulations for 3D printing was performed. Based on commercial materials characterization, the binder jetting process properties requirements were defined. Porcelain powder-based formulations were prepared and evaluated with different binder solutions.

Effect of the surface finish on the mechanical properties and cellular adhesion in (Ce,Y)-TZP/AlO ceramic composites for denture implants.

Ceramic composites based on (Ce, Y)-TZP/AlO system have great potential for applications as dental implants due to their unusually great balance between good mechanical properties and resistance to hydrothermal degradation. Surface roughness plays an important role in controlling these properties, but few studies have investigated the relationship between cytocompatibility and surface roughness, at levels considered moderate and low, comparable to titanium implants. In this work, bending strength, hydrothermal degradation and biological evaluation of a ceramic composite based on (Ce,Y)-TZP/AlO system were investigated as a function of surface roughness.
