“…According to Tsuo et al, recommended air-borne particle size for sintered zirconia is 50 m [20]. Another study concluded that air-borne particle abrasion with either smaller (50 m) or larger (110 m) particles is of beneficial for zirconia with a machined surface in terms of shear bond strength [21,35]. In this study, air-borne particle size of 50 m was used in the SAS group and size of 70 m was selected in the SBS group in order to obtain the similar surface roughness between the two test groups.…”

“…Surface treatments such as air abrasion with aluminum oxide particles roughen the zirconia surface and increase the bond strength 17) . Other surface treatments of zirconia including laser treatment 18,19) , selective infiltration technique (SIE) 20) , hot etching solution 21,22) , nanostructured alumina coating 23) , and slurry-coated ceramic 24) have been developed to improve and enhance the surface roughened area to facilitate the mechanical interlocking of the ceramic and bonding resin.…”

The surface morphology and crystal structure change of dental zirconia after hydrofluoric acid (HF) etching were evaluated. Four groups of sintered zirconia specimens were 1) control group, 2) immersion in 9.5%HF at 25 o C for 1, 2, 3, or 24 h, 3) immersion in 9.5%HF at 80o C for 1, 3, 5, or 30 min and 4) immersion in 48%HF at 25 o C for 30 or 60 min. The specimens were evaluated under SEM and XRD. The SEM analysis revealed changes in surface topography for all the HF-etched zirconia specimens. The irregularities surface increased with increasingly longer immersion times and higher etching solution temperatures. The XRD analysis of the HFetched zirconia specimens revealed the presence of a crystalline monoclinic phase along with a tetragonal form. It was concluded HF can etch dental zirconia ceramic, creating micro-morphological changes. Tetragonal-to-monoclinic phase transformation was induced on the etched zirconia surface.

“…9,[28][29][30] Many research literatures have reported that such airborne particle abrasion treatment on Y-TZP ceramic surfaces can achieve a high bond strength by increasing the roughness of the surface. 29,31,32 In contrast, Kern and Wegner 30 claimed that surface treatment of Y-TZP ceramics with airborne particle abrasion increased the bond strength with Bis-GMA resin cement, but the treatment was not stable for long term storage. In this study, A group treated with airborne particle abrasion showed the lowest bond strength and displayed significantly lower bond strength compared to PC and AC groups which were treated with nano-alumina coating (Table 3).…”

Purpose: The aim of this study was to investigate whether the application of nano-structured alumina coating to the surface of Y-TZP could enhance the bond strength with resin cement. Materials and methods: A total of 80 zirconia plates were prepared and divided into four groups. : 1) airborne particle abrasion treatment (A) : 2) Rocatec treatment after airborne particle abrasion (R) : 3) nano-structured alumina coating treatment after polishing (PC) and 4) nano-structured alumina coating after airborne particle abrasion (AC). Alumina coating was formed by the hydrolysis of aluminium nitride (AlN) powder and heat treatment at 900。 C. Coating patterns were observed with FE-SEM. Resin block was bonded to treated zirconia ceramics using resin cement. The shear bond strengths were measured before and after thermocycling. Results: The FE-SEM images show a dense and uniform nano-structured alumina coating structure, which enhances shear bond strength by increasing micro mechanical interlocking to resin cement. PC and AC groups showed higher shear bond strengths than A and R groups before and after thermocycling. A and R groups displayed significant drops in shear bond strength after thermocycling. However, PC and AC groups did not show any meaningful decreases in shear bond strength after thermocycling. Conclusion: Treatment of Y-TZP ceramics with nano-structured alumina coating could significantly increase their shear bond strength. (J Korean Acad Prosthodont 2016;54:354-63)
