The Effect of Adding Glass Fiber on Recycled Thermoplastic Nylon and a Combination of Water Absorption and Color Stability of Denture Base Material

Introduction

Thermoplastic nylon is a type of polymer that has gained significant attention in the field of denture base manufacturing due to its unique properties, including elasticity, high mechanical strength, light weight, and good aesthetic value. However, the production process of thermoplastic nylon through injection molding techniques generates nylon sprue waste, which has a negative impact on the environment. Therefore, recycling thermoplastic nylon has become an essential aspect of sustainable manufacturing practices. However, the recycling process can alter the physical, chemical, and mechanical properties of nylon, making it crucial to improve the quality of recycled nylon through the addition of glass fiber and the percentage of a combination of pure nylon and recycled nylon.

The Importance of Recycling Thermoplastic Nylon

The demand for thermoplastic nylon in denture base manufacturing has led to the generation of significant amounts of nylon sprue waste. This waste not only contributes to environmental pollution but also poses a significant economic burden on manufacturers. Recycling thermoplastic nylon offers a viable solution to this problem by reducing waste and conserving natural resources. However, the recycling process involves washing and heating, which can alter the properties of nylon. To overcome this challenge, researchers have explored the addition of glass fiber to improve the quality of recycled nylon.

The Role of Glass Fiber in Improving Recycled Nylon

Glass fiber is a common additive used in various polymer materials to enhance their mechanical properties. The addition of glass fiber to recycled thermoplastic nylon can improve its strength, stiffness, and durability. In this study, we aimed to evaluate the effect of adding glass fiber on the water absorption and color stability of denture base materials made from thermoplastic nylon.

Research Design and Methodology

This study employed a laboratory experiment design to evaluate the effect of adding glass fiber on the water absorption and color stability of denture base materials. A total of 54 cylindrical thermoplastic nylon samples measuring 15 mm in diameter and 0.5 mm in thickness were prepared. The samples were divided into six groups, each with a different percentage of glass fiber added to the pure nylon and recycled nylon mixture. The water absorption and color stability of the samples were tested using the Kruskal Wallis test and analysis of variance (ANOVA), respectively.

Results and Discussion

The results of this study showed that the addition of glass fiber did not have a significant effect on water absorption, with a P-value of 0.452, indicating that P > 0.05. However, there was a significant effect on color stability, with a P-value of 0.000, indicating that the addition of glass fiber contributed to increasing color stability. Further analysis revealed that the addition of 1% glass fiber to the base of the denture base did not increase water absorption but contributed positively to color stability.

Conclusion

The use of glass fibers in a recycled and pure thermoplastic nylon mixture serves to improve color stability without worsening the nature of water absorption. This finding provides an alternative way in recycling polymer material, given the importance of aesthetic quality in denture products. Further research can explore more in various percentages of glass fibers or additional materials to reach a more optimal combination.

Recommendations for Future Research

This study has provided valuable insights into the effect of adding glass fiber on the water absorption and color stability of denture base materials made from thermoplastic nylon. However, there are several areas that require further investigation. Some of the recommendations for future research include:

  • Exploring the effect of different percentages of glass fiber on the water absorption and color stability of denture base materials.
  • Investigating the use of additional materials, such as carbon fiber or ceramic particles, to improve the properties of recycled thermoplastic nylon.
  • Evaluating the long-term durability and stability of denture base materials made from recycled thermoplastic nylon with added glass fiber.

Limitations of the Study

This study has several limitations that should be acknowledged. Firstly, the study was conducted in a laboratory setting, and the results may not be representative of real-world applications. Secondly, the study only evaluated the effect of adding glass fiber on the water absorption and color stability of denture base materials, and further research is needed to explore other properties, such as mechanical strength and durability. Finally, the study only used a single type of glass fiber, and further research is needed to explore the effect of different types of glass fibers on the properties of recycled thermoplastic nylon.

Implications of the Study

The findings of this study have significant implications for the development of sustainable denture base materials. The use of recycled thermoplastic nylon with added glass fiber offers a viable solution to the problem of nylon sprue waste and conserves natural resources. Furthermore, the improved color stability of denture base materials made from recycled thermoplastic nylon with added glass fiber can enhance the aesthetic quality of denture products, making them more appealing to patients.
