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.
L'application du processus de frittage laser, dans lequel des pièces façonnées faites d'une poudre de frittage sont formées en couches en exposant successivement chaque couche à l'énergie d'un faisceau laser qui conduit à un frittage local, de sorte que le faisceau laser est guidé au-dessus de la couche de poudre respective au moyen d'un système commandé par ordinateur en utilisant des données qui représentent la configuration du corps façonné dans cette couche, pour la production d'éléments de remplacement de dents (couronnes, bridges, incrustations et autres similaires) et/ou de pièces dentaires, de sorte que la poudre comprenne un matériau biocompatible de granulométrie variant entre 0 et 50 Mu m.
