Abstract

The purpose of this study was to improve the property of photo-cured type denture relining resins. Specimens of three commercial resins were cured under 4 conditions (condition 1: photo-cure follow ing manufacturer's instructions, condition 2: condition 1 +heating at 60 for 15 minutes, condition 3: repeat condition 1 three times, condition 4: condition 3+condition 2).<BR>1. The amount of eluted monomers under conditions 2, 3 and 4 measured by HPLC was decreased compared with that of condition 1.<BR>2. The amount of generated radicals under condition 2, 3 and 4 measured by ESR was decreased compared with that of condition 1.<BR>3. The curing depth, water sorption and transverse strength were increased compared with those of condition 1.<BR>4. The adaptability, surface hardness and surface roughness were not influenced by curing conditions.<BR>The results suggested that condition 4 is the most effective method to improve the property of photo-cured type denture relining resins, and condition 3 is a simple and effective method for clinical use.
