Method for manufacturing denture part from three-dimensional-data i.e. CAD data, involves sintering scaffold body with outer geometry of denture part, where density of material is smaller than final density of denture part

摘要

The method involves sintering a scaffold body (14) with an outer geometry of a denture part (9) made of a ceramic material (8) e.g. zirconia or aluminum oxide, by laser, where density of the material is less than final density of the manufactured denture part to attain final density by a post-treatment. The density of the scaffold body is predefined according to the laser sintering process. The scaffold body is in-filtered with a filler (13), where outer geometry of the scaffold body comprises laser sintering mass corresponding to final dimensions of the manufactured denture part.
