Dimensional changes at the posterior border of baseplates made from a visible light-activated composite resin

Dimensional changes of 50 baseplates made of Triad visible light-cured resin were measured before and after curing, placement in water, and drying on the laboratory bench. Results showed that the resin shrinks but improves on storage in water. For persons sensitized to monomer, no free monomer is present in the material. Therefore, Triad resin offers an alternative to conventional self-curing resins often used to make baseplates.
