Three chairside reline materials were each used to reline ten complete dentures. Comfort, fit, colour change, staining and integrity were assessed at 3, 6, and 12 months post-placement. Working and setting times were obtained using an oscillating rheometer. Tokuso Rebase Fast Set had the shortest working and setting times. It was the most colour stable, stain resistant and durable. Coe Kooliner was difficult to use due to high flow. Total Hard had the longest working and setting times, and the poorest stain resistance and durability. Severe loss of reline materials only occurred 12 months after placement, and then mostly from within lower dentures. No differences between the materials were noted for the other parameters investigated.
