“…this result agrees with the study stated this discovery can be cleared by that soft liner material mixed with silver nitrate filler that promotes the penetration of polymeric chains. When bonded inside a soft liner, it becomes harder and more resistant [16]. There were some studies incorporating (silver benzoate) into resin and studied their effect, the result of this study showed that by adding (silver benzoate) there was a decrease in the degree of curing, resulting in a reduction in Rockwell hardness for light cure resin.…”

The development of polymer chemically produces alternative materials to polymethyl methacrylate, such as nylon, and epoxy resin, these resins are modified by thermoplastic process, and This Received The disadvantage of acrylic resin is the colonization of microorganism growth of fungi and candida adhesion. This study is designed to evaluate and compared the consequence of silver nitrate fillers reinforcement Accepted flexible acrylic hardness as one of the mechanical properties to find the effect of various concentrations. A (0.1and 0. 2) ml of the filler (silver nitrate) additive to the flexible acrylic. Forty five (45) specimens were prepared for testing in this study. The hardness test was used in this study. The sample of this test was divided into (3) groups (control group) and experimental groups as follows: Group A= (15) specimens without silver nitrate (Control group 0% silver nitrate). Group B= (15) specimens with (0.1 ml) silver nitrate. Group C= (15) specimens with (0.2 ml) silver nitrate. All control and test groups were processed; curred then finished and polished the specimens ready for testing. Shore A test against the concentration of silver nitrate the result of this study showed a high significant increase in the mean value of hardness for control groups to the silver nitrate compared with experimental groups.

“…Soft liner with silver nanoparticle shows high water absorption and solubility in contrast to low-level concentration of silver. (9) The addition of silver NPs (0.5, 1, 2, and 3 wt %) and thermocycling of siliconbased soft liner reduces the tensile strength to denture acrylic resin (10) .…”

Aims:To study the effect of metal oxide nanoparticles (MgO, ZrO2, ZnO) on acrylic based soft liner surface properties and FTIR. Materials and Methods: Acrylic-based softliner specimens were prepared by adding three different concentrations (0.5, 1, and 2) %wt of metal oxide nanoparticles (MgO, ZrO2, ZnO). A disk-shaped specimens with 30mm diameter and 3mm thickness were prepared for shore (A) hardness test to evaluate the surface hardness of modified soft liner. The surface roughness of soft-liner samples (10X10X2mm) was tested by a profilometer. FTIR analysis was conducted to evaluate chemical reaction that may occur between acrylic-based soft liner and nanoparticles. Results: there were no chemical reaction carried out between soft liner and metal oxide nanoparticles at different concentration-surface hardness (shore A) was increased as nanoparticles concentration increased in modified resin. Nanoparticles with 1 and 2% concentration incorporated in soft liner had lower surface roughness value. Conclusions: Metal oxide nanoparticles have improved the surface texture of acrylic-based soft liner, while the hardness of modified soft liner was increased with nanoparticles concentration increases.
