Title:
METHOD FOR PRODUCING ALL-CERAMIC DENTAL SHAPED PARTS
Document Type and Number:
WIPO Patent Application WO2002076321
Kind Code:
A3
Abstract:
The invention relates to a method for producing two-membered or multi-membered all-ceramic dental shaped parts such as bridge substructure elements and the like. According to the method, a model is firstly produced from the basic structure, for which the dental shaped part is provided. By using this model and a suspension of ceramic particles, a ceramic base body is formed, in particular by means of electrophoretic deposition, and is subsequently sintered. The method provides that the dimensions of the model are, at least in part, selected in order to compensate for shrinkage resulting from the sintering of the base body whereby achieving, in this manner, the desired fit between the dental shaped part and the basic structure.
