In-situ nano-silica deposition and air-abrasion with Bioglass 45S5 or aluminium oxide: Effects on methacrylate bonding to yttria-tetragonal zirconia polycrystal

The in-situ nano-silica coating method employed in this study may be a suitable, simplified and low-cost approach to provide reliable bond strength to Y-TZP ceramics. No air-abrasion is required after in-situ nano-silica deposition. However, AlO air-abrasion can create micro-retentions on the surface of silica-free Y-TZP ceramics and increases the immediate bond strength of methacrylate-based resin cements.
