Summary

Full ceramic materials are suitable for tooth restorations because or their beneficial aesthetical properties and high biocompatibility in comparison to metal containing dental prosthesis. Zirconia shows the best mechanical properties from all ceramic materials, which are eligible for dental application. At present, fully-densified zirconia dental crowns or bridges can be manufactured by means of CAD-CAM supported mill-cutting techniques only. But these methods are time consuming and expensive. Furthermore, the exact acquisition of the tooth geometry by means of mechanical or optical scanning techniques is rather problematical. In contrast, zirconia dental restorations, e. g. crowns, can be fabricated near-shape in a fast, well controllable and cost efficient way using electrophoretic deposition from aqueous suspensions (membrane method) and subsequent sintering. Using suspensions with extremely high solids loading and polymodal particle size distribution green bodies with a comparably high green density, high green strength and a narrow pore size distribution can be manufactured. Thus, linear shrinkage of the green bodies during sintering to full density can be minimized to less than 10 %. The samples show a homogenous microstructure and wall-thickness.
