[Temperature change during polymerization of self-curing resin for rebasing].

Maximum temperatures, time elapsed to reach them and setting times of four kinds of self-curing resins for rebasing were measured during polymerization at 37 degrees C with attention to curing conditions which might lead to the discomfort of patients in direct rebasing. The temperatures were lower and both times were longer than those of ones for making temporary crowns. When varying thickness of the resins, the maximum temperature and the setting time significantly increased depending on an increase in the thickness, although the time elapsed to reach the maximum temperature showed no difference. All values measured were remarkably influenced by pre polymer powder/monomer ratios.
