Abstract
AIMS: The aim of the study undertaken was to evaluate an effective method of denture repair, which will have considerable transverse and impact strength, quick to repair and can be effectively utilized by the general practitioner.
 OBJECTIVES: 1) To evaluate the transverse strength of denture base resin repaired by different methods having 45° joint surface contours and compare it with denture base acrylic resin repaired by conventional methods.
 2) To find out the best material for repair.
 MATERIAL AND METHODS: For the purpose of this study, Heat cure resin (DPI), Autopolymerising resins (DPI) and Glass Fibers (interling), were taken from the market. The unrepaired conventional heat cure denture base resin (DPI heat cure) plates were used as control group. . 
 RESULTS:
 1) The mean transverse and impact strength of all the samples repaired by various methods showed significantly lower strength than control group (heat cure unrepaired samples used as control for transverse strength) 103.33MPa, although statistically significant.
 2) Specimens repaired by self cure resin with glass fibers having 450 bevel joint showed the highest transverse strength.
