Surface Characterization of Current Dental Ceramics Using Scanning Electron Microscopic and Atomic Force Microscopic Techniques

Dental ceramics is a highly esthetic material and its surface properties can impact roughness, bonding properties, as well strength wear. The aim of the study to analyze characteristics by determination roughness parameters three dental used in computer-aided design/computer-aided manufacturing (CAD/CAM) technique: lithium disilicate (LS2), zirconium oxide-reinforced silicate (ZLS), oxide (ZrO2), prepared using two different processing techniques, polishing (self-glaze) glazing with glazes. Both glass ceramics, pre-crystallized LS2 crystallized ZLS, were cut into disks, was ground polished. Crystallization performed for samples, while ZrO2 samples fabricated CAD/CAM sintered. Then, glaze applied reheated per manufacturer’s instructions. contact topographies tested measured atomic force microscopy (AFM) parameters: average (Ra), root-mean-square (Rq), area difference (SAD) evaluated. Changes morphological examined scanning electron (SEM), chemical composition determined attenuated total reflection Fourier-transform infrared spectroscopy (FT—IR). In spectroscopic analysis, characteristic signal obtained ZLS samples. A significant decrease observed after all (p < 0.05). abstract should be an objective representation article it must not contain results that are presented substantiated main text exaggerate conclusions.
