“…It is anticipated that the hydrogen bonds and the van der Waals interaction that form between the nanofiller and polymer will enhance the rigidity and shear strength of the material, in addition, the MMTNPs function as fillers by occluding voids between soft liner particles and improving the surface area for denture base material adherence, more importantly; the size of the sample used (25 mm long by 25 mm wide) is considered to be large, this might be used in the improvement of bonding. 19 Hardness is among the most crucial characteristics of materials for soft denture liner since it reduces the effect of absorption. 20 In this investigation, the distribution of MMTNPs throughout the matrix may be responsible for the rise in hardness.…”

Objective: One problem with the soft lining material is that it detaches from the acrylic base of dentures after a particular time period. So, the aim of this work was to evaluate how adding Montmorillonite nano clay would affect the soft lining material's shear bond strength and surface hardness. Materials and Methods: The heat-cured acrylic denture material for the control group, polymer reinforced with (0.25%,0.5% by wt.) of montmorillonite nanoparticles for experimental groups was used in this study. For the shear bond strength test 60 blocks of acrylic-based material were constructed, each pair connected with soft lining material, the other 30 specimens for the surface hardness tests were carried out. to be tested with a shore A durometer. The data were statistically examined using the One-Way ANOVA test and Bonferroni multiple comparisons test. Result: 0.5% by weight MMTNPS should significantly increase in both shear bonding strength and surface hardness . Conclusion: MMTNPs were remarkably successful in improving the the strength of the shear connection between acrylic and soft liners.

The Effects of Incorporating Ag-Zn Zeolite on the Surface Roughness and Hardness of Heat and Cold Cure Acrylic Resins

One of the most widely used materials for the fabrication of prosthetic dental parts is acrylic resin. Its reasonable mechanical and physical properties make it a popular material for a wide range of dental applications. Recently, many attempts have been made to improve the mechanical and biological properties of this material, such as by adding fibres, nanoparticles, and nanotubes. The current study aimed to evaluate the effects of adding an antimicrobial agent, Ag-Zn zeolite, on the surface roughness and hardness of the denture base resins. Ag-Zn zeolite particles were chemically prepared and added at different concentrations (0.50 wt.% and 0.75 wt.%) to the heat cure (HC) and cold cure (CC) acrylic resins. Zeolite particles were characterized and confirmed using X-ray diffraction (XRD) and Energy-Dispersive X-ray Spectroscopy (EDX) attached with a Scanning Electron Microscope (SEM). Sixty disk shape specimens (40 mm diameter and 2 mm thickness) were fabricated from the HC and CC resins with and without the zeolite. All the specimens were divided into two main groups based on the acrylic resins, then each was subdivided into three groups (n = 10) according to the concentration of the Ag-Zn zeolite. A surface roughness and a hardness tester were used to measure the surface finish and hardness of the specimens. The analysed data showed that the surface roughness values significantly decreased when 0.50 wt.% and 0.75 wt.% zeolite were incorporated in the HC resin specimens compared to the control group. However, this reduction was not significant in the case of CC resin, while the surface hardness was significantly improved after incorporating 0.50 wt.% and 0.75 wt.% zeolite for both the CC and HC resins. Incorporating Ag-Zn zeolite with acrylic resin materials could be beneficial for improving their surface finish and resistance to surface damage as defined by the higher hardness.
