This study evaluated the effects of sandblasting and coating techniques on volume loss, surface morphology and composition changes in pure titanium. Sandblasting is recommended as a pretreatment to thermal silica coating (Silicoater MD) or as part of a tribochemical silica coating process (Rocatec). Silica coating titanium improves chemomechanical bonding. The combination of MDP-containing primer and luting cement following tribochemical silica coating to Y-TZP was the best choice among the alternatives tested in this study.Įffects of sandblasting and silica-coating procedures on pure titanium. Among the MDP-containing groups, the group with MDP-containing primer and resin cement showed significantly higher SBS values than the other groups ( p < 0.05). The group with MDP-free primer and resin cement showed significantly lower SBS values than the MDP-containing groups ( p < 0.05). After a shear bond strength (SBS) test, the data were analyzed using 1-way analysis of variance and the Tukey test (α = 0.05). The forty tribochemical silica-coated Y-TZP specimens were cemented to the bovine dentin (4 groups n = 10) with either an MDP-free primer or an MDP-containing primer and either an MDP-free resin cement or an MDP-containing resin cement. The bonding surface of the Y-TZP specimen was sandblasted with silica-coated aluminium oxide particles. The Y-TZP specimen was prepared in the form of a cylinder with a diameter of 3 mm and a height of 10 mm. The dentin specimens were embedded in molds, with one side of the dentin exposed for cementation with the zirconia specimen. Forty bovine teeth and Y-TZP specimens were prepared. This study investigated the effect of continuous application of 10-methacryloyloxydecyldihydrogen phosphate (MDP)-containing primer and luting resin cement on bond strength to tribochemical silica-coated yttria-stabilized tetragonal zirconia polycrystal (Y-TZP). Lim, Myung-Jin Yu, Mi-Kyung Lee, Kwang-Won The effect of continuous application of MDP-containing primer and luting resin cement on bond strength to tribochemical silica-coated Y-TZP. Application of silane yielded better durable bond strengths of a layering indirect composite material to a tribochemically silica-coated zirconia framework material. Post-thermocycling shear bond strengths of ZR-PLU were higher than those of ZR-PRE in CCP, MGP+Act, SIL, PZA+PZB, and PZB groups. Shear bond testing was performed at 0 and 20,000 thermocycles. Bond, Super-Bond PZ Primer Liquid A with Liquid B (PZA+PZB), and Super-Bond PZ Primer Liquid B (PZB), or no treatment. Indirect composite was bonded to zirconia treated with one of the following primers: Clearfil Ceramic Primer (CCP), Clearfil Mega Bond Primer with Clearfil Porcelain Bond Activator (MGP+Act), ESPE-Sil (SIL), Estenia Opaque Primer, MR. Zirconia disks were divided into two groups: ZR-PRE (airborne-particle abrasion) and ZR-PLU ( tribochemical silica coating). This study evaluated shear bond strengths of a layering indirect composite material to a zirconia framework material treated with tribochemical silica coating.
