dc.description.abstractStatement 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 SiO2, TiO2, or ZrO2 (n=11) at a thickness of 30 nm, whereas control specimens were left uncoated (n=11) (airborne-particle abraded only). The surface roughness of the specimens was analyzed with a profilometer before applying porcelain (Vita Titankeramic). Titanium-porcelain bonding was analyzed by using a 3-point bend test. Surface properties and titanium-porcelain interfaces were examined under scanning electron microscopy combined with energy-dispersive spectroscopy, and failure types were evaluated by using a stereomicroscope. Surface roughness and bond strength data were analyzed by 1-way ANOVA and Tukey HSD tests. Failure type data were analyzed by the Fisher-Freeman-Halton exact test (?=.05). Results: All nanocoatings increased surface roughness values, but only TiO2 and ZrO2 coatings showed statistically significant higher roughness than the control surfaces (P<.001). Specimens coated with SiO2 (28.59 ±4.37 MPa) and TiO2 (26.86 ±3.66 MPa) presented significantly higher bonding strength than control (22.04 ±4.59 MPa) specimens (P<.01). Fracture types of different groups were not statistically different (P>.05). Conclusions: Nanocoating titanium surfaces with SiO2 and TiO2 by using the ALD technique significantly improved titanium-porcelain bonding. © 2021 Editorial Council for the Journal of Prosthetic Dentistry
