Abstract
The purpose of this study was to investigate bond strength of denture base resin repairedaccording to contamination. One commercial denture base resin and two different kinds of relinesresin were tested; Lusiton 199(denture base resin), Vertex(reline resin) and TokusoRebase(repairresin). The specimens were processed according to the manufacturer’s instructions to cured denturebase resin(polymethylmethacrylate; PMMA) and reline resin. Bond strengths were examined byuse of a three-point transverse flexural strength test. Data were analyzed with two-factor analysis ofvariance and Duncan’s post-hoc test at =0.05. Generally, the bondstrength of heat-curedresin(Lusiton 199) was higher than the other resins. The contaminations produced an decrease inbond strength. Therefore the contamination, such as saliva or water must be avoided during thelaboratory repair procedures.
