Statement Of Problem: Durable titanium-porcelain bonding is challenging because of the formation of a thick oxide layer on the surface during porcelain firing.
Purpose: The purpose of this in vitro study was to evaluate how atomic layer deposition (ALD) of different oxide coatings affected titanium-porcelain bonding and failure types.
Material And Methods: Forty-four airborne-particle abraded Type-2 titanium specimens were coated by ALD with either SiO, TiO, or ZrO (n=11) at a thickness of 30 nm, whereas control specimens were left uncoated (n=11) (airborne-particle abraded only).
Purpose: The purpose of this study was to compare the fracture resistances and the fracture types of titanium, zirconia, and ceramic-reinforced polyetheretherketone (PEEK) implant abutments supporting CAD/CAM monolithic lithium disilicate ceramic crowns after in vitro dynamic loading and thermocycling aging.
Materials And Methods: Three implant abutment (SKY Implant) groups-titanium (group Ti, control); zirconia with titanium base (group Zr); and ceramic-reinforced PEEK (BioHPP) with titanium base (group RPEEK); n = 12 each-were used. Thirty-six CAD/CAM monolithic lithium disilicate crowns (IPS e.
