Promoting porcelain –zirconia bonding using different atmospheric pressure gas plasmas

With its renowned strength and stability, yttria-stabilized tetragonal zirconia (YTZ) has been recognized as a suitable material to fabricate anterior and posterior dental prostheses. The evolution of CAD –CAM technologies has overcome the design and manufacturing limits of YTZ and expanded its applications [1]. Contemporary all-ceramic prostheses are composed of zirconia copings and various veneering porcelain to support the chewing functions and esthetic appearance. Although the bilayer YTZ resto rations have achieved acceptable clinical outcomes, they revealed higher failure rates compared to metal-ceramic counterparts [2,3].
