evaluation of the effect of temperature and time on the conversion factor of acrylic resin denture base material
Abstract
The aims of this study were to evaluate the effect of change
in time ,temperature (increase or decrease) on the degree of
conversion and residual monomer release of the vertex heat
cured acrylic resin. Materials and methods: The total number
of samples (176) were divided into three main groups cured
according to ADA and three curing cycles with modifications
in time and temperature, degree of conversion and residual
monomer properties were measured for all the samples.
Results were analyzed statistically by (Descriptive statistics,
ANOVA and Duncans multiple range test) and showed that
both changes in time and temperature showed significant
changes in the degree of conversion, residual monomer.
Conclusion is that the rapid simplified and regular
manufacturers instruction curing cycles showed the best
results regarding the degree of conversion, residual monomer.
