Method for accurate replication of shaped articles using sinterable powders

摘要

Shaped articles such as dental onlays and inlays having at least one surface adapted to mate with a mating surface of a second shaped article are produced by a procedure which includes immersing a swellable polymer casting mold in a swelling agent system to swell such casting mold to an extent which compensates for the shrinkage which occurs when a sinterable powder compact made therein or in a solid replica thereof, is heated.
