The present study investigated the ability of the reline material to strengthen denture base materials processed by other means. Materials and Methods: Four denture base materials were tested for flexural strength at proportional limit (FSpl) with or without being relined. Results: The reline material maintained the FSpl of the microwave-processed and the autopolymerizing denture base materials. It increased the FSpl of the heat-processed and the light-activated denture base materials. Conclusion: The light-cured reline material increased the flexural strengths of the heat-processed and the light-activated denture base materials and maintained those of the microwave-processed and the autopolymerizing denture base materials.
