Repair resins maybe:Heat cure ORSelf cureHeat cured resinThese resins are cured at 74oC for 8 hours or more. The use of a heat-cured resin will tend to warp the denture during processing.Self-cured resinAlthough the repair with a self-cured resin invariably has a lower transverse strength than that of the original heat-cured denture base resin, self-cured resins are usually preferred because warpage is insignificant as curing is done at room temperature.Reference: Mannapallil Basic SCIENCE OF DENTAL MATERIALS, 4th ed page no 561
