Modifying the Setting Rate of an Addition-Type Silicone Impression Material

Two methods for controlling the working time of an addition-type silicone impression material are presented. The progress of the polymerization reaction of this modified system was studied using viscosity and a new "compression set" technique. The physical properties are presented and compared to those typical of condensation silicones, and a method of clinical use is suggested.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68081/2/10.1177_00220345790580041301.pd
