Abstract (en)
[origin: WO2006084425A1] The invention relates to a method and device for producing by electrophoresis fully ceramic tooth elements having a predefined spatial shape, wherein an electric conductive plate (1) having different conductive areas is applied to a working model or a structural element directly or at a certain distance. According to a known method, a power is supplied to the plate by means of a cable, which is removable after coating by means of a slip and prior to sintering. According to the inventive method, said laborious operation is nor required anymore. The inventive method consists in fixing the plates (1) to a conductive tooth stump (2) by means of an adhesive conductive material (5) or to an implant abutment (3). The power can be supplied by the tooth stump, the abutment or a leg (7) integrateable with the plate. Said plate is preferably made of zinc or an adhesive conductive material, preferably a mixture of wax and zinc powder which disappears without residues by sintering. A plate which is particularly suitable for carrying out said method and whose conductivity variations are obtainable by means of recesses embodied therein is also disclosed.
