Abstract

Application of the laser sintering process, in which shaped pieces made of a sintering powder are built up in layers by exposing each layer successively to the energy of a laser beam that leads to local sintering, whereby the laser beam is guided over the respective powder layer by means of a computer-controlled system using data that represent the configuration of the shaped body in this layer, for the production of tooth replacement elements (crowns, bridges, inlays and the like) and/or dental parts, whereby the powder comprises a biocompatible material of varying grain size between 0 and 50 µm.
