[Supplemental studies on self-curing resins. 2. On polymerizing temperature of reline materials]

The objective of this study was to find the best way to keep down the peak temperature of self-curing reline materials. The experiments were done by using three kinds of self-curing reline materials (Rebaron, REBASE and KOOLiner) and three kinds of the reline materials of different thickness (1.5mm, 2mm and 3mm) under three different intraoral conditions. When these reline materials cured under rinsing the mouth with cold water (18 degrees C), the data analysis of these reline materials showed a considerable reduction in the peak curing temperatures clinical acceptance. The results obtained were as follows: 1. Both extraoral and interoral curing tests showed that the thicker the material is the higher the peak temperature becomes. 2. Highly significant differences in time to the peak temperature were found among the three kinds of reline materials. 3. Dangerously high temperature was found in polymerizing of the thickest material, 3mm.
