Abstract

The process is designed for the production of dental prostheses or parts thereof from polymerizable plastic. The easy-flowing plastic is introduced into a hollow area (3') which corresponds to the shape of the prosthesis, limited on the one side by the plaster cast (3) and on the other side by an upper mould section (4) which maintains the tooth arrangement (14) and altogether surrounds the free surfaces of the plaster cast (3). In a polymerization vessel (1) the plastic is polymerized in a bowl (2) which contains the plaster cast (3) and the upper mould section (4). In order to improve the matching precision of the prostheses produced, a lower pressure than that of the other also locally-open regions is applied through one or several open points (6) on the underside of the base of the plaster cast (3) at the latest during polymerization of the plastic.
