Document Type and Number:
WIPO Patent Application WO2006005284
Kind Code:
A3
Abstract:
The invention relates to methods and devices for producing denture elements, whereby surface data of a remaining dental area are digitally acquired, at least one molded part, especially a denture element for the remaining dental area, is three-dimensionally designed using the surface data of the remaining dental area acquired and corresponding mold data are produced, and the at least one denture element is partially or completely produced on the basis of the surface data and mold data, with one or more of the following aspects being taken into consideration: dimensionally designing web constructions between tooth stumps and producing corresponding mold data; acquiring surface data of a three-dimensional dental impression, on one side, on two sides or on several sides; graphically representing the surface data, fixing at least one mark on the graphical representation of the surface data, and constructing mold data for a denture element based on the surface data and taking into consideration the mark in the graphical representation of the surface data; producing primary crowns by means of 3+1 axes milling or angular axis milling techniques; optimally aligning a milled blank with the element to be milled by "uphill/downhill milling"; and or using for scanning the molding waxes a molding wax including at least 1/3 to 4/5 parts by weight of zirconium oxide powder.
