Abstract
A screening test for hardness and one for porosity were carried out in order to find the best and most practical technique for curing heat-cure acrylic crown and bridge resin. The test-curing conditions were: 20% NaCl solution; 206[degrees]F curing temperature; 150 PSI. The curing time was 45 minutes. Physical property tests were run on specimens cured in test conditions and compared to physical property tests done on specimens cured in a conventional technique. The test curing procedure gave a material, the hardness of which was found to be significantly higher due to surface indentation and, possibly, more resistant to abrasion. The results of blanching, tensile and bonding tests did not indicate that the test material was superior to the control. In the fade test it was found that the control was slightly better. Clinical and laboratory procedures and practical applications of the curing technique are herein discussed.
