ABSTRACT:
A method of manufacturing artificial tooth veneer restorations for natural teeth composed of a ceramic core by pressing and sintering ceramic powder. The core is preferably manufactured from a high strength densely sintered ceramic material by copy milling from an impression of the prepared tooth surface to a compacted body, a presintered body or a sintered body. Alternatively, the core is manufactured by compacting the ceramic powder against a body, which surface is copy milled from a model of the prepared tooth surface. During the copy milling, the sintering shrinkage is considered by enlargement of that body. The tooth veneer restorations are given their final shape by shaping the external surface of the compacted, presintered or sintered ceramic body. After the final sintering, the external surface can be shaped before a veneer material is attached to the external surface of the core by firing of dental porcelain. Manufacturing ceramic teeth veneer restorations according to the method of this invention increases their strength and accuracy to shape.
