The Effect of the Addition of Amplifier and Thermocycling Material on the Transversal Strength in the Base of the Heat Polymerization Resin Denture

The base of the denture is a crucial component in restoring the function of mastication and aesthetics for the user. Heat polymerization acrylic resin (RAPP) is often an option in making denture bases due to its ease of formation and processing. However, RAPP has a significant weakness, namely low transverse power. This makes the base of the denture vulnerable to fractures, especially when subjected to pressure during chewing. To overcome this weakness, researchers have been exploring the addition of reinforcement materials such as glass fibers and polyethylene fibers to the RAPP. The hope is that the addition of these reinforcing materials can increase transverse strength and make the base of the denture more durable.

The Importance of Transversal Strength in Denture Bases

Transversal strength is a critical factor in determining the durability of denture bases. A denture base with low transverse strength is more prone to fractures, which can lead to discomfort and embarrassment for the user. Moreover, a fractured denture base can compromise the overall success of the denture, requiring costly and time-consuming repairs or even replacement. Therefore, it is essential to develop denture bases with high transverse strength to ensure optimal function and aesthetics for the user.

The Role of Thermocycling in Denture Bases

Thermocycling refers to the repeated exposure of denture bases to different temperatures, simulating the dynamic conditions of the oral cavity. This can affect the strength of the denture base, particularly in the presence of reinforcement materials. Researchers have been investigating the impact of thermocycling on the transverse strength of RAPP denture bases reinforced with glass fibers and polyethylene fibers.

Experimental Study Design

This study employed an experimental design to investigate the effect of thermocycling on the transverse strength of RAPP denture bases reinforced with glass fibers and polyethylene fibers. The study used a RAPP denture base sample with three variations: without reinforcement material, with the addition of a small piece of e-glass fiber, and with the addition of polyethylene UHMWPE woven fibers. Each variation was then divided into two groups: groups that were not thermocycled and groups that were thermocycled 3000 cycles. The sample transverse strength was then measured and analyzed statistically.

Results

The results of this study showed that thermocycling had no significant effect on transverse strength in all sample groups, either without reinforcement material, with e-class glass fiber, or with polyethylene UHMWPE fibers. This indicates that the cycle of changes in temperature that occurs in the oral cavity does not reduce the strength of the denture base that is reinforced.

However, further analysis revealed that the addition of reinforcement materials, both e-class and polyethylene UHMWPE glass fibers, significantly increased the transverse strength of RAPP dentures, both with and without thermocycling. These results indicate that the addition of reinforcement materials is an important factor in increasing the transverse strength of the RAPP denture base.

Discussion

The findings of this study provide important insights into the effect of thermocycling on the transverse strength of RAPP denture bases reinforced with glass fibers and polyethylene fibers. The results suggest that the addition of reinforcement materials is a critical factor in increasing the transverse strength of the RAPP denture base, regardless of thermocycling exposure.

Conclusion

In conclusion, this study provides valuable information for professionals in the field of dentistry, particularly in the selection of materials and techniques for making denture bases. By using reinforcing materials such as glass fibers and polyethylene fibers, the base of the denture can be made stronger and more durable, thus providing more optimal benefits for users. The findings of this study highlight the importance of considering the addition of reinforcement materials in the design and fabrication of denture bases to ensure optimal function and aesthetics for the user.

Recommendations

Based on the findings of this study, the following recommendations can be made:

Use of reinforcement materials: Denture bases should be made with the addition of reinforcement materials such as glass fibers and polyethylene fibers to increase transverse strength.
Selection of materials: The selection of materials for denture bases should be based on their ability to withstand thermocycling and maintain their transverse strength.
Design and fabrication: The design and fabrication of denture bases should take into account the addition of reinforcement materials to ensure optimal function and aesthetics.

Limitations

This study has several limitations that should be considered when interpreting the results. Firstly, the study used a limited number of sample groups, which may not be representative of all possible scenarios. Secondly, the study only investigated the effect of thermocycling on transverse strength and did not consider other factors that may affect the durability of denture bases. Finally, the study did not investigate the long-term effects of thermocycling on the transverse strength of RAPP denture bases.

Future Directions

Future studies should aim to investigate the long-term effects of thermocycling on the transverse strength of RAPP denture bases reinforced with glass fibers and polyethylene fibers. Additionally, studies should explore the use of other reinforcement materials and their effects on the transverse strength of denture bases. Furthermore, studies should investigate the impact of thermocycling on the durability of denture bases in different clinical scenarios.

Conclusion

In conclusion, this study provides valuable insights into the effect of thermocycling on the transverse strength of RAPP denture bases reinforced with glass fibers and polyethylene fibers. The findings of this study highlight the importance of considering the addition of reinforcement materials in the design and fabrication of denture bases to ensure optimal function and aesthetics for the user.
