Ceramics and Surface Treatments

Modern all-ceramic systems can be categorized based on their glass and crystalline content. A ceramic with high glass content will exhibit excellent esthetics, whereas a ceramic with high crystalline content will provide superior strength. Ceramics can be classified into three categories based on composition: porcelains (feldspathic), glass ceramics (leucite-reinforced, lithium silicate, and lithium disilicate), and polycrystalline ceramics (zirconia and alumina).
