Abstract: 576,034. Moulding synthetic resin dentures. GATES, W. E. F., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 8, 1943, No. 20498. [Class 87 (ii)] In making dentures from a mixture of a polymerizable ethenoid composition and a polymerized ethenoid composition, a resilient gasket 5 is disposed between the two halves of the plaster investments 2 in a dental flask 3 and the flask is placed in a spring-loaded clamp, the compression of the gasket compensating for the contraction which takes place during the polymerization of the composition. Initially, a wax model of the denture, mounted on a plaster model 1, is invested in the lower half of a flask and a resilient gasket or ring is embedded in the surface of the plaster in the lower half of the flask. When the plaster has hardened, the gasket or ring is removed and the investment completed, a continuous elevated ridge 6 being thus formed on the plaster in the upper half of the flask (in the 'channel formed by the gasket). The gasket is then replaced and the ridge symmetrically reduced so that when the two flask halves are re-assembled, a gap exists therebetween. The wax is removed from the flask, the ethenoid composition mixture inserted in the cavity 4 and the flask placed in a spring-loaded clamp. The gasket may be made up of several thinner gaskets. Specification 484,343, [Group IV], is referred to.
