The Effectiveness of the Addition of Silicone Dioxide Nanoparticles (SiO2) to the Flexural Strength and Surface Hardness of the Base of Heat Polymerization Resin Denture (RAPP): Systematic Study

Introduction

Complete dentures play a crucial role in replacing missing teeth and providing adequate support and retention to the upper and lower jaws. One of the primary materials used to fabricate the base of dentures is heat polymerization acrylic resin (RAPP). Although RAPP offers several advantages, including aesthetics, ease of manipulation, and non-toxicity, its flexural strength and surface hardness are relatively low, making it vulnerable to breakage. The addition of reinforcement materials, such as nanoparticles silicon dioxide (SiO2), is expected to improve these characteristics.

Background

Heat polymerization acrylic resin (RAPP) is a widely used material in dentistry due to its ease of manipulation, non-toxicity, and aesthetic appeal. However, its flexural strength and surface hardness are relatively low, making it prone to breakage. The addition of reinforcement materials, such as nanoparticles silicon dioxide (SiO2), has been proposed as a potential solution to improve the mechanical properties of RAPP. SiO2 nanoparticles have been shown to enhance the flexural strength and surface hardness of various materials, including polymers and ceramics.

Purpose of the Study

The purpose of this systematic study is to analyze the effectiveness of the addition of silicone dioxide nanoparticles (SiO2) to the flexural strength and surface hardness of the base of heat polymerization resin denture (RAPP). This study aims to provide a comprehensive review of the existing literature on the use of SiO2 nanoparticles in RAPP and to identify the optimal concentration of SiO2 that can improve the mechanical properties of RAPP.

Methodology

This systematic study was conducted using the prism method as a guide for selecting relevant journals. The database used as a source was Pubmed and Google Scholar, with searches conducted using keywords in the Boolean, Picos, as well as predetermined inclusion and exclusion criteria. To eliminate duplicated journals, the Mendeley application was used as a citation manager. Each stage of this systematic study was well recorded to ensure transparency in the research process.

Results

A total of 5 qualified journals were selected for examination, published between 2012 and 2022. The results of the analysis showed that one journal concluded that there was an increase in flexural and surface hardness in the RAPP denture base with a concentration of nanoparticles SiO2 by 3%, 5%, and 7%. Three other journals showed an increase in concentrations of 1% and 5%. However, there was one journal that reported a decrease in effectiveness at a concentration of 3%, 5%, and 7%.

Discussion

Based on the information obtained from the selected journals, it can be concluded that the concentration of silicone dioxide nanoparticles is 1%, 3%, and 7% produces relatively low flexural strength and surface hardness on the base of RAPP artificial dentures. Meanwhile, a concentration of 5% SiO2 shows the most significant increase in flexural and surface hardness. This confirms that the selection of the right nanoparticles concentration is very crucial to improve the mechanical properties of the material.

Conclusion

The results of this systematic study suggest that the addition of silicone dioxide nanoparticles (SiO2) can improve the flexural strength and surface hardness of the base of heat polymerization resin denture (RAPP). The optimal concentration of SiO2 that can achieve this improvement is 5%. This study highlights the importance of considering the use of SiO2 nanoparticles in the development of denture materials. With the right use, this nanoparticles can significantly increase the strength and durability of artificial dentures, thus providing long-term benefits for patients. Further research is also needed to understand the mechanisms that underlie this mechanical properties and to explore other combinations of nanoparticles that can improve the performance of artificial dental base materials.
