“…Previous study reported that 5% ZrO 2 nanoparticles were biocompatible materials in increasing compatibility with polymers to enhance the impact and transverse the strength of the denture. 9 The porosity of the acrylic resin denture base with ZrO 2 nanoparticle filler demonstrated significant differences between groups. The control group, acrylic resin with ZrO 2 in a concentration of 2.5% and 5% and had a significant value.…”

“…It is a Zirconium dioxide (ZrO 2 ) nanoparticle material characterized by great strength and hardness, non-abrasiveness, non-toxicity, biocompatibility, and low thermal conductivity. 9 ZrO 2 nanoparticles has been validated through in vitro and in-vivo research and thus its application is recommended in dental and other biomedical treatments. ZrO 2 nanoparticles are also recommended for coating materials on PMMA.…”

“…ZrO 2 with 2% and 5% concentration is a biocompatible material which increases affinity with polymers to increase the impact and transverse strength. 9 Nevertheless, adding ZrO 2 nanoparticles above 7% concentration is not recommended because it changes the acrylic resin color. 11 Furthermore, the addition of ZrO 2 to PMMA is likely to develop a denture base material that is reliable, flexible, tough, break-resistant, and provides excellent hardness.…”

Acrylic resin is the most common fabricated material for denture bases. ZrO2 nanoparticles can be used as filler to strengthen the physical properties and inhibit the adhesion of acrylic resins. This study aimed to examine the growth of Candida albicans and porosity in reinforced acrylic resin with Zirconium Dioxide (ZrO2) nanoparticles at 2.5% and 5% a concentration targeted for denture bases application. A laboratory experiment study included twenty-seven disc-shaped samples which were divided into three groups: group I acrylic resin without ZrO2 nanoparticles (control), group II acrylic resin with 2.5% ZrO2 nanoparticles, and group III with 5% ZrO2 nanoparticle acrylic resin. Samples were collected by heat polymerization while porosity observations were done using primo zeizs starr (Nikon YS100) microscope at 100x magnification. Dilution test was implemented to assess Candida albican growth. One-way ANOVA and Post Hoc LSD test statistical analysis were performed to evaluate the data (p<0.05). The results indicated that the mean porosity values in the control group of 2.5% and 5% were 37.4 ± 3.5, 15.8 ± 3.3, 8.0 ± 2.0 respectively while the attachment of C. albicans was 0.832 ± 0.083, 0.536 ± 0.098, 0.218 ± 0.083. One-way ANOVA confirmed a significant effect (p<0.05). Similarly, Post Hoc LSD test reported significant difference (p<0.05). The results showed that acrylic resin reinforced with ZrO2 nanoparticles for heat-polymerized denture base effectively reduced porosity and C. albicans adhesion. Five percent of ZrO2 nanoparticle concentration presented greater porosity reduction compared to 2.5% ZrO2 and non-reinforced acrylic resin. Acrylic resin reinforced with ZrO2 nanoparticles in 2.5% and 5% concentration is fungistatic.

“…The results showed various transverse power values in the same group, and the varying results can be caused by several factors that affect the sampling process. 11 The presence of residual monomer content that acts as a plasticizer would weaken the polymer bond chain allowing deformation to occur more easily and altering the strength values. The second factor is due to the manual stirring technique and the possibility of air trapping in the heat polymerized acrylic resin matrix and internal porosity, which is not visible on the sample surface.…”

Heat-cured acrylic resin is easily fractured and can be prevented by adding reinforcing materials of duck eggshell powder. Furthermore, it can be used as a biocompatible reinforcing material due to the high content of CaCO3. This study aims to determine the effect of adding 2.5% and 5% duck eggshells as reinforcement for the denture base with heat-cured acrylic resin on the transverse strength. The method is an laboratory experiments with a post-test only control design conducted on January 2022. The samples were made by adding a reinforcing agent of 2.5% and 5% heat-cured acrylic resin powder’s weight in a mould sized 65 x 10 x 2.5 ± 0.5 mm with 11 samples in each group. The curing process was executed at a temperature of 70°C for 90 minutes before increasing to 100°C for 30 minutes, and the transverse strength of acrylic resin was measured using the Universal Testing Machine. The sample tested using univariate analysis with the results of the average transverse strength in the control group 66.59 ± 1.88 MPa, after adding 2.5% duck eggshell 72.61 ± 3.05 MPa and 5% duck eggshell 86.14 ± 4.09. The one-way ANOVA and LSD tests showed significant results with p-value = 0.001 (p < 0.05) and 0.001 (p <0.05). The highest transverse strength value of heat-cured acrylic resin was found in the 5% duck eggshell group, followed by 2.5%, and lastly, the control group.
