Aim: 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.
Material 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: Analyzed statistically by (Descriptive statistics, ANOVA and Duncan’s multiple range test) and showed that both changes in time and temperature showed significant changes in the degree of conversion, residual monomer.
Conclusion: The rapid simplified and regular manufacturer’s instruction curing cycles showed the best results regarding the degree of conversion, residual monomer.

Keywords: Temperature, Time, Conversion factor, Acrylic resin.
