Abstract

This study would like to measure and compare water sorption and solubility of acrylic resins, with 3 different polymerizing methods, and tensile strength between denture base resin and relining rosins. For this experiment, 3 different acrylic resins were used; heat polymerizing resin: Vertex (Dentmex, Zeist, Holland), autopolymerizing resin: Tokuso Rebase (Tokuyama Corp, Tokyo, Japan), and light curing resin: Mild Rebaron LC(GC Corp, Tokyo, Japan) The results were as follows ; 1. Tokuso Rebase showed the lowest water sorption. followed by Mild Rebaron LC and Vertex. Among resins, there were some signigicant differences (P<0.05). 2. Vertex showed the lowest solubility, followed by Mild Rebaron LC and Tokuso Rcbase. Among resins, there were some signigicant differences (P<0.05). 3. Intact Vertex showed the highest tensile strength, and Mild Rebaron LC had a more tensile strength than Tokuso Rebase. Between Vertex and the other resins, there were some signigicant differences (P<0.05) However, between Mild Rebaron LC and Tokuso Rebase, there was no statistical difference (P>0.05). About 50% of Rebaron LC showed cohesive fracture. 4. Tensile strength has more decreased after thermocycling than before, but there was no statistical difference (P>0.05).
