The nanocomposites were characterized by X-ray diffraction (PXRD), field emission scanning electron microscopy (FE-SEM), and Fourier transform infrared spectroscopy (FTIR). The rate of drug release was also tested. The Minitab 18 program was used to analyze the results. The independent variables were the CS, TPP, and pH, while loading efficiency, zeta potential, and particle size were the dependent variables.

The surface roughness (Ra) before and after incubation was recorded using a non-contact optical profilometer. The monomer leaching and the surface roughness of the tested materials depended on the pH value of the saliva. The conventional denture framework material exhibited the highest and lowest leaching rates at pH=4.5 and pH=3.5, respectively, regardless of the treatment method. Among the CAD/CAM processed materials, the 3D-printed material showed the highest and lowest leaching at pH=5.5 and pH=3.5, respectively.

The bentonite particle size was determinedby the XRD method using the Debye-Scherrer equation. The diffraction of the laser beam was used todetermine particles size distribution. The addition of bentonite nanoclay significantly improved tensilestrength (26-61% and 99–118% in the warp and weft direction, respectively) and tear strength (4‒13%and 5–24% in the wrap and weft direction, respectively) of coated fabrics.
