The flexural strengths of denture base acrylic resins after relining with a visible-light-activated material.
OBJECTIVE
Previous studies disclosed the ability of a light-activated denture reline material to strengthen a particular denture base material. The present study investigated the ability of the reline material to strengthen denture base materials processed by other means.


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.


CONCLUSIONS
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.
