This research evaluated the bond strength between one heat-cured acrylic resin (Lucitone 550®) and two hard chairside reline resins, after two different periods of storage in water (50 h and 30 days). The bond strength was evaluated using a tensile test. The mode of failure, adhesive or cohesive, was also recorded. The results submitted to the Kruskal-Wallis test indicated that the highest tensile strengths were achieved with intact Lucitone 550® denture base resin in both periods of storage in water. After 50 h of storage in water, Duraliner II® reline material exhibited the highest bond strength to the denture base resin. After 30 days of storage in water, Duraliner II® reline resin demonstrated a significant reduction in adhesion, showing lower tensile bond strength than Kooliner® material. Both hard chairside reline materials failed adhesively across Lucitone 550® denture base resin, in both periods of time. © 1999 Blackwell Science Ltd.631-634engacrylic acid resinduraliner IIkoolinerLucitonewateradhesionchemistrydental bondingdenturehumanmaterials testingsurface propertytensile strengthtimeAcrylic ResinsAdhesivenessDental BondingDenture BasesDenture LinersDenture RebasingDenture RetentionHumansMaterials TestingSurface PropertiesTensile StrengthTime FactorsWaterArtigo10.1046/j.1365-2842.1999.00428.xWOS:000082046300003Acesso restrito2-s2.0-0033173493573712733424854930031305224278200000-0002-7375-4714
