“…In addition, Monaco et al 20 obtained the hightest bond value with pre-sintered 110 lm Al 2 O 3 sandblasting in their study. They claimed that the values for SBS of sandblasting of pre-sintered zirconia were statistically significant, and they found that Group S compared with Group C showed higher bond values on average; however, the shear bond strengths between Group S and Group C were not significantly different (p = 0.866).…”

“…Many surface treatments are applied for obtaining a better bond with resin cement or veneering porcelain to the surface of post-sintered ZrO 2 . 10,15,21,22,[24][25][26][27]33,34 Sandblasting, 10,15,16,[18][19][20][21][22][24][25][26][27][28][29] mechanical grinding, 16 silica coating, 20,21,25 plasma spray treatment, hydrofluoric acid treatment, 26,28 and liner 10,23 treatment are the majority of these treatments. Recently, with the development of lasers used in dentistry, a laser-etching 4,15,17,18,[24][25][26] method has been used.…”

Objective: The aim of this study was to evaluate the effect of different surface treatments: sandblasting, liners, and different laser irradiations on shear bond strength (SBS) of pre-sintered zirconia to veneer ceramic. Background data: The SBS between veneering porcelain and zirconium oxide (ZrO 2 ) substructure was weak. Various surface treatment methods have been suggested for zirconia to obtain high bond strength to veneering porcelain. There is no study that evaluated the bond strength between veneering porcelain and the different surface treatments on pre-sintered ZrO 2 substructure. Methods: Two hundred specimens with 7 mm diameter and 3 mm height presintered zirconia blocks were fabricated. Specimens were randomly divided into 10 groups (n = 20) according to surface treatments applied. Group C, untreated (Control); Group E, erbium:yttrium-aluminum-garnet (Er:YAG) laser irradiated; Group N, neodymium:yttrium-aluminum-garnet (Nd:YAG) laser irradiated; Group SB, sandblasted; Group L, liner applied; Group NL, Nd:YAG laser irradiated + liner applied; Group EL, Er:YAG laser irradiated + liner applied; Group SN, sandblasted + Nd:YAG laser irradiated; Group SE, sandblasted + Er:YAG laser irradiated; and Group SL, sandblasted + liner applied. The disks were then veneered with veneering porcelain. Before the experiment, specimens were steeped in 37°C distilled water for 24 h. All specimens were thermocycled for 5000 cycles between 5°C and 55°C with a 30 sec dwell time. Shear bond strength test was performed at a crosshead speed of 1 mm/min. The fractured specimens were examined under a stereomicroscope to evaluate the fracture pattern. Results: Surface treatments significantly changing the topography of the yttrium-stabilized tetragonal zirconia (Y-TZP) ceramic according to scanning electron microscopic (SEM) images. The highest mean bond strength value was obtained in Group SE, and the lowest bond strength value was observed in NL group.Bond strength values of the other groups were similar to each other. Conclusions: This study shows that sandblasting + Er:YAG, sandblasting, Er:YAG + liner, sandblasting + Nd:YAG, and Er:YAG laser treatment on pre-sintered ZrO 2 substructure increased the bond strength to veneering porcelain, compared with other surface treatments. After different surface treatments, there was no difference in surface roughness of pre-sintered zirconia to compare after sintering; sintering enhanced the bond strength within the limitations of present study.

“…Air-borne particle abrasion, also defined as sandblasting, is usually performed by aluminum oxide particles and is one of the most commonly used mechanical methods for surface preparation of zirconia copings 3) . This technique roughens the ceramic surface and increases the surface area for bonding, thus enhancing the bond strength [27][28][29] . Some authors considered surface damage and significant removal of substances from the surface as drawbacks of the sandblasting procedure, which can cause a reduction in flexural strength of the ceramics 3,30) .…”

Aims:The present study investigated the effect of different surface treatments on shear bond strength (SBS) of resin cement to zirconia. Materials and methods: Ninety zirconia blocks were prepared and divided into 6 groups of 15 by treatment. Group 1 served as the control group, whereas groups 2 and 3 were treated with air abrasion and a universal primer (Monobond plus), respectively. The remaining zirconia copings were treated with a fractional CO2 laser for 10 seconds using 10 W/10 mJ (group 4), 10 w/14 mJ (group 5) or 20 W/10 mJ (group 6). A luting cement (Clearfil SA) was bonded to the treated zirconia surfaces and cured for 40 seconds. SBS was measured with a universal testing machine and the type of bond failure was determined. Results: There was a statistically significant difference in SBS among the study groups (p<0.001). The highest SBS values were observed in the groups treated with the fractional CO2 laser at settings of 20 W/10 mJ (28.1 MPa) or 10 W/14 mJ (27.4 MPa), followed by the specimens treated with the universal primer (22.8 MPa). The control specimens exhibited the lowest SBS (9.4 MPa) among the study groups (p<0.05). There was no significant difference in the distribution of failure modes among the groups (p=0.871). Conclusions:The application of fractional CO2 laser can improve bond strength of resin cement to zirconia ceramic, and thus it could be considered as an appropriate alternative to conventional methods of zirconia surface treatment.

“…The 120 μm alumina particles provided significantly higher roughness mean values and a slightly more pronounced topography than the other three particles (Figs A, D, G, J). Monaco et al also found that for the air‐abrasion before zirconia sintering, the alumina particles (50 and 110 μm) promoted higher SBS values than the 30 μm silica‐coated ones; however, they reported no significant difference between the 50 μm and 110 μm alumina particles. It seems that, at the BS moment, the roughness may have played a more decisive role in the SBS.…”

Roughness was influenced by the particle size and was higher when the zirconia was air-abraded in its green stage. The particle composition played an important role in the wettability and both studied air-abrasion moments provided similar wettability than the one in which air-abrasion is usually performed. The highest SBS values were observed in the three moments, by using certain particles for each moment.

Pilot Evaluation of Four Experimental Conditioning Treatments to Improve the Bond Strength between Resin Cement and Y-TZP Ceramic

Abstract: Within the limitations of this study, additional surface treatment with air abrasion before and after sintering provided a significant increase in bond strength. Tribochemical silica coating before sintering was not effective as a surface treatment.
