Transverse Strength of Repaired Denture Base Material with Wire and Two Auto Polymerized Acrylic Resin

Objective: the purpose of this study was to evaluate the transverse strength of one brandof denture base material repaired with two autopolymerized acrylic resins with and withoutwire reinforcement.materials and methods: eighty samples (2.5پ~10پ~65 mm3) were fabricated and dividedinto five groups. the control group was left intact. groups b and d specimens were repairedwith autopolymerizing acrylic resins. groups a and c specimens were repairedwith metal wire and autopolymerizing acrylic resins. after 48 hours of storage at 37پ‹c, thetransverse strength of the specimens was measured with a universal testing machine. datawere analyzed by one way anova and duncan test (ƒ؟=0.05).results: significant differences were found between the control group and the other experimentalgroups (p<0.05). among experimental groups, group d showed the highesttransverse strength with the mean value of 40.2 (sd=11.8) mpa while group b present the lowest transverse strength of 28.4 (sd=5.4) mpa. the difference between the transversestrength of group d and the other groups was statistically significant (p<0.05). conclusion: 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 repairedspecimens (p<0.05). the application of wire significantly reduces the transverse strength of the meliodent repaired groups (p<0.05), however the changes occurred in tran
