Yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) is a ceramic material that has been widely used in clinical practice owing to its attractive proven mechanical properties and biocompatibility. Since zirconia is a chemically inert material, different surface treatments can be performed to increase its bonding to resin-based cements. Air abrasion with alumina or silica-coated alumina particles is one of the most common and simple procedures used to improve micromechanical interlocking between zirconia and resin-based cements. These particles are deposited on the surface, which differ chemically from one another, and participate in the chemical bond that occurs at the zirconia–resin cement interface.
COLOGNE, Germany: In the lead-up to the 38th International Dental Show (IDS), Dental Tribune International (DTI) held its 15th Annual Publishers’ Meeting over 10 and 11 March in Cologne. This year’s gathering saw 75 members of the DTI network from all over the globe in attendance to discuss the latest developments and projects the company is undertaking.
