Bond Strength between Zirconia Y-TZP and Resin Cements: Evaluation of Surface Treatment, Cure Mode, and Failure Types

Abstract

Y-TZP, yttria-stabilized tetragonal zirconia polycrystalline; Al 2 O 3 , aluminum oxide; MDP, phosphate ester monomer 10-methacryloyloxydecyl dihydrogen phosphate. Standardization of the cementing surface All zirconia cylinders had their surface planed and polished with 320, 600, and 1200 grit wet sandpaper in a metallographic polisher for 10s for each grit. Then, the cylinders were cleaned in an ultrasonic vat with 92.8INPM ethanol for 10min. After cleaning, they were blotted dry for 1min and then blown with dry, oil-free air for 10s.

EFFECT OF DIFFERENT SURFACE TREATMENT PROTOCOLS ON THE RETENTION OF POSTERIOR PEEK CROWNS (A randomized invitro study)

“…Also, a homogenous cement mix was done with care using a stainless-steel spatula, and evenly distributed on the crowns intaglios using a penbrush. Dual curing was also shown to significantly improve the bond strength between resin cement and zirconia Y-TZP (13) accordingly, dual cured cement was used with PEEK crowns.…”
