title: A subjective study of dimensional stability of permanent acrylic resin complete denture bases after a second curing cycle.
abstract: The aim of this study was to subjectively assess permanent denture base retention and stability in order to determine whether detrimental change occurred as a result of a second curing cycle. 100 complete upper denture bases were assessed by clinician and patient using visual analogue scales at try-in and insert. No statistically significant alteration in mean scores for retention and stability was seen. 5% of bases showed some deterioration, but none required rebasing or remaking as a result. The advantages of permanent bases during denture construction seem to outweigh the risk of loss of retention and/or stability as a result of distortion due to the second curing cycle.
