Samples in this study were heat-polymerized
acrylic resin material (QC-20, England) without E-glass fiber as control group and heat-polymerized
acrylic resin with chopped strands 3 mm size E-glass fiber (Cam Elyaf San A.S., Kocaeli, Turkey) with 1% and 1.5% concentration.
PMMA
acrylic resin was mixed in the ratio of 1 gm of powder to 0.45 cc of liquid, for 15 seconds, to produce a creamy mixture.
On the other hand, there was statistical significant relationship (p=0.009) between the age of denture and the type of fracture as illustrated in Table 5 which shows that with increasing age of denture
acrylic resin fracture is more likely.
Furthermore, biocompatibility of Autopolymerized
acrylic resin has been studied by different researchers who suggested that this material is cytotoxic.23-25
After wax elimination, packing was done with heat cure clear
acrylic resin, and after trial closure, final closure was done.
Water-soluble
acrylic resin can disperse in water with the help of hydrophilic organic solvents due to its molecules with hydrophilic groups such as carboxyl and hydroxyl.
In the present study, vertex rapid simplified heat cure
acrylic resin was used and it also contained cross- linking agent so it can be assumed that because of the cross-linking of the
acrylic resin, the surface hardness remained unaffected after immersing into the disinfectant solutions in both the studies.
The data were further subjected to statistical analysis and it showed that the maximum marginal discrepancy was found with cold cure
acrylic resin and minimum with of GC light cure
acrylic resin when the samples were subjected to thermocycling.
Additional verification of adequate
acrylic resin thickness may be achieved at the packing stage using a periodontal probe, allowing recontouring of the putty at that time if required (9).
