The comparison of denture-base processing techniques. Part I. Material characteristics.
Some of the physical properties for three techniques for processing acrylic resin were tested. Tests included: (1) thickness changes from a standard die which simulated the palatal and flange regions of a denture, (2) relative Rockwell surface hardness, (3) color stability, and (4) surface detail. The three processing techniques under investigation were: (1) an all-stone investing technique, (2) a silicone-gypsum investing technique, and (3) a fluid-resin technique.
