Strength Impak Acrylic Resin Of Heat Polymerization After The Addition Of Silica 2, 5 And 10% Of The Weight Synthesized From The Shells Of Blood Shells (anadara Granosa)
Introduction
Heat polymerization acrylic resin is a widely used material in the field of dentistry for making dentures. Despite its numerous advantages, one of the main disadvantages of this resin is its relatively low impact strength. To overcome this problem, the addition of silica particles (SiO2) is often done, as silica is known to improve the mechanical properties of acrylic resins, including impact strength. In this study, a blood shell (Anadara granosa) rich in silica is used as a filler in making denture bases. The purpose of this study is to determine the effect of adding silica in concentrations of 2%, 5%, and 10% of weight to the strength of heat acrylic resins.
Background
Acrylic resins have been widely used in dentistry for making dentures due to their ease of use, low cost, and good aesthetic properties. However, one of the main disadvantages of acrylic resins is their relatively low impact strength, which can lead to fractures and breakage of dentures. To overcome this problem, various fillers have been added to acrylic resins, including silica particles (SiO2). Silica is known to improve the mechanical properties of acrylic resins, including impact strength, due to its high hardness and resistance to wear.
Materials and Methods
In this study, heat polymerization acrylic resin samples were made in the form of plates measuring 65 x 10 x 2.5 mm. Each treatment, including the control group, was tested with ten resin samples. The silica used was obtained from the extraction of blood shell shells. The manufacturing process started with making molds using white casts, where acrylic resin mixtures with a proportion of 9 grams of resin and 4.5 ml of liquid were inserted. The polymerization process was carried out in a waterbath with a temperature of 74 ° C for 1.5 hours, followed by a temperature of 100 ° C for one hour. After that, the sample was polished to get a flat and smooth surface.
Experimental Design
The strength of the impact of the acrylic resin was tested using an Izod Impact Tester tool with an angle of 20 ° and the weight of a beating 5.5 joules. The test results showed the mean value of the impact strength for each group, namely: the control group (23.68 ± 1.63 J/m²), the group with the addition of 2% silica (27.07 ± 1.47 J/m²), the group with the addition of 5% silica (26.02 ± 0.87 J/m²), and the group with the addition of 10% silica (19.85 ± 1.34 J/m²). Statistical analysis using the One Way Anova and Post Hoc LSD test showed a significant difference in the strength of the impact between groups, with a value of P = 0,000 (p <0.05).
Results and Discussion
Based on the results, it can be concluded that the addition of silica nanoparticles significantly affects the strength of the impact of heat polymerization resins. In particular, the addition of silica at a concentration of 2% and 5% shows an increase in the strength of the impact compared to the control group. However, interestingly, the addition of silica at a concentration of 10% actually decreases the power of impact compared to the control group. This shows that there is an optimal limit in the use of silica, and excess silica can interfere with the mechanical properties of acrylic resins.
Conclusion
This study is very relevant for the development of a stronger and durable denture base material, and opens opportunities for further research on the use of natural materials as fillers in dental composites. With the right development, these materials can provide more efficient and environmentally friendly solutions in dentistry practices.
Future Directions
Further research is needed to explore the optimal concentration of silica for use in heat polymerization acrylic resins. Additionally, the use of other natural materials as fillers in dental composites should be investigated to develop more sustainable and environmentally friendly solutions in dentistry practices.
Limitations
This study has some limitations, including the use of a small sample size and the limited number of concentrations of silica tested. Future studies should aim to increase the sample size and test a wider range of concentrations of silica to confirm the findings of this study.
Implications
The findings of this study have significant implications for the development of stronger and more durable denture base materials. The use of natural materials as fillers in dental composites can provide more efficient and environmentally friendly solutions in dentistry practices. This study highlights the potential of using blood shell shells as a source of silica for use in heat polymerization acrylic resins.
Recommendations
Based on the findings of this study, it is recommended that further research be conducted to explore the optimal concentration of silica for use in heat polymerization acrylic resins. Additionally, the use of other natural materials as fillers in dental composites should be investigated to develop more sustainable and environmentally friendly solutions in dentistry practices.
