Method of manufacture of dental prostheses and auxiliary elements

Abstract

For the production of dental prostheses and / or dental auxiliary parts, the use of the laser sintering method is proposed, in which layered moldings are built up from a sinterable powder by successively exposing each layer of the powder to a local laser sintering energy of a laser beam, wherein the leadership of Laser beam over the respective powder layer is subject to the control of data representing the configuration of the shaped body in this layer, wherein the powder consists of a biocompatible material of different grain size between 0 and 50 microns.
