The current production of tooth restorations in zirconia involves classic CAD/CAM milling of pre-sintered zirconia blocks, which wastes material, introduces machining defects and limits the potential for individual aesthetic characterization unless the zirconia core is veneered with porcelain. During clinical functioning the latter bi-layered structure unfortunately results too often in chipping defects. Additive manufacturing, i.e. ...
