Method for the precise fabrication of dental components using a sintering or selective laser melting process

摘要

The invention relates to a method for fabricating dental components. A set of geometric data is provided for the three-dimensional description of at least one desired dental component, and based on these geometric data a three-dimensional CAD model of the dental component is created. The CAD model processes the geometric data in the form of layer data to generate numerous CAD model layers which are suitable for use in a laser sintering or laser melting process. The laser sintering or laser melting process is then carried out, based on the layer data for each individual CAD model layer, and with computer assistance a powdered material is correspondingly applied in layers on a fabrication platform. Following the laser sintering or laser melting process, the body of the dental component having the resulting layered construction is transferred to a heat treatment oven, is subjected to heat treatment, and is subsequently cooled.
