“…Sandblasting as described for group 1, followed by sandblasting with silica powder 30 µm, for 10 s; 3. Sandblasting as described for group 1(application of graphite power) 46 Usumez et al gained acceptable results by increasing pulse energy and pulse duration at 1-minute irradiation as well. 32 In the reviewed studies, time of irradiation was between 5 seconds to 2 minutes and it needs to be further studied as it seems an important factor in the final result.…”

To achieve proper bond strength for porcelains, adequate surface roughness is essential, which is traditionally gained by sandblasting or acid etching with hydrofluoric (HF) acid. Nowadays with the development of laser systems, serious efforts were made to apply this new instrument for surface etching of porcelains due to easy usage, safety, and more efficiency. There are different kinds of lasers and porcelains, so choosing the ones which will be good match for each other is crucial. Besides that, changing the irradiation setting can be beneficial as well. This article reviewed 33 related studies and summarized results of etching accomplished by Nd:YAG, Er:YAG, Er,Cr:YSGG and CO 2 lasers on different types of porcelains considering different laser settings and evaluation methods to bring a comprehensive insight.

“…It specifically attaches to the silicon molecule on the bonding surface, and a siloxane network comprising covalent bonds is formed by dehydration and condensation. This is known to produce a strong bond to silica 5,11,12) . Y-TZP is a polycrystal zirconia ceramic without silica on the surface, so surface modification of Y-TZP is required before SCA application 13,16,30) .…”

“…Many surface-treatment methods have been attempted for dental ceramics, including etching [7][8][9][10] , alumina sandblasting (ASB) 5,6) , laser etching 11) and plasma etching 12) . In particular, etching for dental ceramic restorative materials treated with several acid solutions is believed to increase surface area because these solutions selectively dissolve the glassy component of the ceramic [7][8][9][10] .…”

Combination treatment of tribochemical treatment and phosphoric acid ester monomer of zirconia ceramics enhances the bonding durability of resin-based luting cements

et al. 2010

The aim of the present study was to evaluate the bonding durability of resin-based luting cement to partially stabilized tetragonal zirconia (Y-TZP) achieved by combination treatment of tribochemical (TBC) treatment and two different phosphate acid ester monomers. Two phosphate acid ester monomers (EP: Epricord opaque primer, AZ: AZ primer) were applied to each surface modification followed by application of resin-based luting cement (Rely-X ARC). Bonding specimens were placed in deionized water at 37°C and stored for 24 h. The other groups were subjected to 30,000 cycles of a thermal stress for the durability test. Shear bond tests were done using a universal testing machine at 1 mm/min. Shear bond strengths of combination treatments using EP and AZ on TBC treatment after thermal stress showed no significant difference (p>0.05) compared with those of storage after 24 h. Combination treatment using phosphoric acid ester monomer could achieve a durable bond.

Dental zirconia can be etched by hydrofluoric acid

et al. 2014

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.
