The Investigation of Solubility Values, Water Sorption and Bond Strength of Auto-polymerising and Heat-polymerising Acrylic Resin Materials
Abstract
Abstract - In this study the solubility, water sorption and the bond strength of auto-polymerising and heat-polymerising acrylic resins were investigated. Two auto-polymerising and ï¬ve heat polymerising acrylic resin materials were used for this study. Thirty-ï¬ve specimens were prepared (50 mm in diameter and 0.5± 0.01 in thickness) for water sorption and solubility tests. In order to examine bond strength, specimens were prepared in 2.5x10x64 mm dimensions. These specimens were repaired with QC and major repair acrylic. Some specimens were kept in distilled water for 50 hours, and others for 30 days. The strength of the bond was measured by a Pull-Compress device. As a result of the variance analysis; water sorption, solubility and the bond strength between acrylic resins were identiï¬ed as statistically signiï¬cant (P<0.001). The water sorption of the major acrylic resin specimens were lower than the other materials(P<0.001).
KEY WORDS: Solubility, Water sorption, Bond strength, Auto-polymerising acrylic resin, Heat-polymerising acrylic resin.
