摘要

STATEMENT OF PROBLEM: Some problems of the self-curing or autopolymerizing resins may include color instability and dimensional inaccuracy. PURPOSE: This study compared the color and dimensional stability of the new autopolymerizing resin Unifast II, which combines a new activator with some existing products. RESULTS: The change in color (delta E value) of Unifast II resin was less than that demonstrated for four autopolymerizing resins (Unifast, Curefast, ADFA, and MIKY). Unifast II did not exhibit color change when stored in conditions below 37 degrees C. Unifast II also had a significantly better fit than the other four autopolymerizing resins (p < 0.01). No significant differences in transverse strength were observed among Unifast II, Unifast, and ADFA, but the Unifast II autopolymerizing resin maintained its color stability and dimensional accuracy without sacrificing its transverse strength.
