1. A method of fabricating a denture base disc, the method comprising:
a) filling a cavity formed within a mold vessel with an uncured denture base material, the mold cavity bounded by a first compressible liner contiguous with a bottom wall of the vessel; b) fitting a removable mold top comprising a second compressible liner on an inner surface thereof to the top opening of the vessel; c) applying pressure to the uncured denture base material, thereby compressing the first and second compressible liners from an uncompressed state to a compressed state; d) curing the uncured denture base material into an at least partially cured and solid state, wherein the at least partially cured solid state denture base material shrinks to a lesser volume than the uncured denture base material, and wherein the first and second compressible liners expand from a compressed state to a less compressed state, the expansion in compressible liner volume substantially equal to the volume of shrinkage of denture base material during the at least partial curing. |
