Abstract
A denture base is made of a photocuring resin compound by a process which includes polymerizing methacrylate and/or acrylate with the addition of a light sensitizer or a filler. Subsequent to a proper alignment of artificial teeth, the photo-curing or -hardening resin compound is hardened by exposure to light and artificial gingivae are formed by the same resin compound as above, followed by photocuring, thereby completing manufacture of the denture base. Advantageously, the method disclosed herein facilitates markedly the manufacture of denture bases in comparison with conventional methods such as thermal polymerization and casting. The resulting denture bases show excellent properties.
