Improving the Mechanical Strength of Acrylic Resin: An Investigation into the Effects of Hydroxyapatite from Tilapia Scales

Introduction

Acrylic resin has long been a popular choice for creating denture bases due to its numerous advantages. However, one of its significant drawbacks is its relatively low mechanical strength, making it prone to breakage. To overcome this limitation, researchers have been exploring various strategies to enhance the mechanical properties of acrylic resin. One such approach is the addition of hydroxyapatite, a compound known for its excellent biomineral properties. This study aims to investigate the effect of adding hydroxyapatite from tilapia scales on the impact strength of heat-polymerized acrylic resin.

The Importance of Hydroxyapatite in Biomedical Applications

Hydroxyapatite is a naturally occurring mineral found in bones and teeth, making it an ideal candidate for biomedical applications. Its excellent biocompatibility, bioactivity, and mechanical properties make it an attractive material for various medical applications, including bone grafting, dental implants, and tissue engineering. In this study, hydroxyapatite was synthesized from tilapia scales using the calcination method to produce high-quality hydroxyapatite powder.

The Role of Silanization in Enhancing Hydroxyapatite Adhesion

To improve the adhesion of hydroxyapatite to the acrylic resin, a silanization process was employed. This process involves the reaction of hydroxyapatite with a silane coupling agent, which creates a strong chemical bond between the hydroxyapatite and the resin. This modification is crucial in ensuring that the hydroxyapatite particles are evenly distributed throughout the resin and do not agglomerate, which can lead to a decrease in mechanical properties.

Research Methodology

This study involved the manufacture of acrylic resin samples measuring 65x10x2.5 mm, divided into four treatment groups: a control group without the addition of hydroxyapatite, and three groups receiving 2%, 5%, and 8% additional hydroxyapatite. Each sample group was processed with a predetermined ratio between acrylic resin, hydroxyapatite, and monomer. Curing was done through a water bath at a regulated temperature, followed by the process of channeling using sandpaper with different grit numbers.

Sample Making and Testing Process

To measure the impact strength of the samples, the Izod Impact Test was used. This test involves striking a notched sample with a pendulum, and the energy absorbed by the sample is measured. The performance data was analyzed through the one-way ANOVA test and Post Hoc (LSD Test) to determine the significance of the differences between the treatment groups.

Results and Discussion

The results showed that the impact strength of the control group (without hydroxyapatite) had an average of 20.99 ± 3.62 J/m². However, after the addition of hydroxyapatite, the impact strength decreased: the 2% group recorded 15.85 ± 0.75 J/m², the 5% group recorded 16.37 ± 0.81 J/m², and the 8% group recorded 15.08 ± 0.41 J/m². The one-way ANOVA test showed that there were significant differences in the impact strength (p = 0.00, p < 0.05), and the LSD test showed a significant variation between the treatment groups.

Conclusion

Overall, this study concluded that the addition of hydroxyapatite from tilapia scales in the acrylic resin of heat polymerization actually caused a decrease in impact strength. This finding suggests that although hydroxyapatite is known to have many benefits in biomedical applications, higher concentrations in acrylic resins may disrupt their mechanical structure. Further research is needed to explore modifications or other methods that can improve the mechanical properties of acrylic resin in this application.

Implications and Future Directions

This study has important implications for the development of more durable and sustainable dental prosthetic materials. The use of tilapia scales as a source of hydroxyapatite provides a potential solution for reducing waste and promoting eco-friendly practices in the dental industry. Furthermore, the findings of this study highlight the need for further research into the effects of hydroxyapatite on the mechanical properties of acrylic resin. By exploring alternative methods for improving the mechanical strength of acrylic resin, researchers can develop more effective and sustainable solutions for dental prosthetics.
