Abstract

Objective: The objective of the study was to analyze the flexural strength (FS) of polymethyl methacrylic resin processed with short curing cycle after incorporating 0%, 0.5%, and 5% concentrations of silver nanoparticle’s as antimicrobial agent. Materials and Methods: The use of universal testing machine (Instron, Model No. 5967) by collecting the FS values from specimens for analytical interpretation in three subgroups
with incorporation of 0%, 0.5%, and 5% concentration of colloidal silver nanoparticle’s cured with short curing cycle. Microsoft Excel Software (SPSS for Windows Version-20) (2010) helped to evaluate the absolute count of FS parameters of each specimen of three subgroups and to summarize data into the forms of tables. Results: In comparison with the three subgroups, the mean FS of modified denture base resin by adding silver nanoparticles was gradually decreased at concentrations (0%, 0.5%, and 5%). At short curing cycle, modified denture base resin showed lower FS than unmodified resin. Conclusion: The method of curing process proved that short curing cycle is good and time saving process due to uses of terminal boiling temperature which cause/produce fast and complete polymerization reaction for curing the denture base resin.
