TRANSVERSE STRENGTH OF REPAIRED DENTURE BASE MATERIAL WITH WIRE AND TWO AUTO POLYMERIZED ACRYLIC RESIN

摘要

Objective: The purpose of this study was to evaluate the transverse strength of one brand of denture base material repaired with two autopolymerized acrylic resins with and without wire reinforcement.Materials and Methods: Eighty samples (2.5×10×65 mm³) were fabricated and divided into five groups. The control group was left intact. Groups B and D specimens were repaired with autopolymerizing acrylic resins. Groups A and C specimens were repaired with metal wire and autopolymerizing acrylic resins. After 48 hours of storage at 37^oC, the transverse strength of the specimens was measured with a universal testing machine. Data were analyzed by one way ANOVA and Duncan test ( a =0.05).Results: Significant differences were found between the control group and the other experimental groups (PConclusion: In wire reinforced groups, there was no significant difference between two types of acrylic resin (P=0.93), however in repaired groups without wire, the type of acrylic resin generates a significant difference in the transverse strength of the repaired specimens (P
