Effect of chilled monomer on working time and transverse strength of three autopolymerizing acrylic resins.
Samples of three commercially available poly(methyl-methacrylate) autopolymerizing resins were made by using room temperature and chilled monomer. Working and setting times and transverse strengths were determined. The following conclusions can be drawn: 1. Working and setting times increased approximately 2 to 4 minutes when chilled monomer was used. This could be advantageous in certain situations. 2. Transverse strength decreased approximately 17% with the use of chilled monomer. The clinical significance of this decrease is not known.
