“…7,11,35 Several treatments have been used in studies to improve bonding properties of these materials. 7,15,20,22,24,29,30,36,37 Recently, it has been suggested that the application of plasma can lead to enhanced zirconia-resin bonding by making changes on the surfaces of Y-TZP.

“…12 These surface modifications are based on roughening the surface and increasing its wettability. [13][14][15][16] Conventional adhesion techniques used for silica-based ceramic (such as etching by hydrofluoric acid) cannot be used for zirconia ceramics, because it fails to achieve adequate surface roughness and will lead to poor bonding strength. 10,[17][18][19] The airborne Al 2 O 3 particle abrasion of zirconia ceramics surface has been found an effective method for achieving durable ceramic-resin bonding.…”

Introduction:In recent years, the use of ceramic base zirconia is considered in dentistry for all ceramic restorations because of its chemical stability, biocompatibility, and good compressive as well as flexural strength. However, due to its chemical stability, there is a challenge with dental bonding. Several studies have been done to improve zirconia bonding but they are not reliable. The purpose of this research is to study the effect of plasma treatment on bonding strength of zirconia. Methods: In this in vitro study, 180 zirconia discs' (thickness was 0.85-0.9 mm) surfaces were processed with plasma of oxygen, argon, air and oxygen-argon combination with 90-10 and 80-20 ratio (n=30 for each group) after being polished by sandblast. Surface modifications were assessed by measuring the contact angle, surface roughness, and topographical evaluations. Cylindrical Panavia f2 resin-cement and Diafill were used for microshear strength bond measurements. The data analysis was performed by SPSS 20.0 software and one-way analysis of variance (ANOVA) and Tukey test as the post hoc. Results: Plasma treatment in all groups significantly reduces contact angle compare with control (P = 0.001). Topographic evaluations revealed coarseness promotion occurred in all plasma treated groups which was significant when compared to control (P < 0.05), except argon plasma treated group that significantly decreased surface roughness (P < 0.05). In all treated groups, microshear bond strength increased, except oxygen treated plasma group which decreased this strength. Air and argon-oxygen combination (both groups) significantly increased microshear bond strength (P < 0.05). Conclusion: According to this research, plasmatic processing with dielectric barrier method in atmospheric pressure can increase zirconia bonding strength.

Statement of problem. Yttria-stabilized zirconia used for the fabrication of crowns and fixed\ud \ud prostheses may require intraoral adjustments after placement and cementation. Grinding and\ud \ud polishing methods may result in changes in the surface characteristics of zirconia.\ud \ud Purpose. The purpose of this in vitro study was to assess the effect of polishing procedures on\ud \ud surface roughness, topographical and phase changes of zirconia, and wear of the opposing dentition.\ud \ud Material and methods. Presintered and precut yttria-stabilized zirconia specimens (10×10×1 mm)\ud \ud were divided into 4 groups (control, Intensiv, Shofu, 3M ESPE) depending on the polishing method\ud \ud used to prepare the specimens. All tests were carried out in triplicate. The specimens were polished\ud \ud depending on the polishing regimen, while the control was left untreated. The specimens were\ud \ud thermocycled for 3000 cycles, with a temperature range of 5C to 55C. The surface roughness,\ud \ud elemental, and phase changes caused by polishing before and after thermocycling were assessed\ud \ud with surface profilometry, energy-dispersive spectroscopy, and X-ray diffraction analysis. The wear on\ud \ud antagonist steatite balls was also measured after mastication simulation. Statistical analysis was\ud \ud performed using 1-way ANOVA and the Tukey post hoc test to perform multiple comparison tests (a=.05).\ud \ud Results. The polishing procedures increased surface roughness (Ra) of yttria-stabilized zirconia from\ud \ud 0.52 for the control specimen to 0.73 for Intensiv, 0.70 for Shofu, and 0.70 for 3M ESPE (P<.05), which\ud \ud was reduced by thermocycling to 0.44 (control), 0.58 (Intensiv), and 0.58 (Shofu) (P<.001), while\ud \ud roughness remained unchanged for 3M ESPE specimens (0.75; P=.452). The deposition of aluminum\ud \ud when using Shofu abrasives and nickel in Intensiv was demonstrated. Phase changes were observed\ud \ud on the zirconia surface with formation of the monoclinic phase in all polishing methods. Specimen\ud \ud aging enhanced the surface phase changes and also induced compressive stresses in zirconia\ud \ud polished with Intensiv. The different polishing protocols did not affect the wear to the antagonist (P>.05).\ud \ud Conclusions. Polishing zirconia increased surface roughness and led to surface phase changes, but\ud \ud wear to the antagonist was not affected.peer-reviewe

The present study aims to examine the effects of operational parameters on the surface topography and wear mechanisms of monolithic and conventional yttria‐stabilized zirconia (Y‐TZP) ceramics in the micro blasting process, performed under various acceleration pressures (1.5–3 bar), particle impact angles (30°–90°), and erodent particle sizes (50–460 μm). Three‐dimensional (3D) surface topography, surface roughness, and surface morphology of micro‐blasted specimens were analyzed by using non‐contact optical profilometry and SEM‐EDS. The micro blasting characteristics of both Y‐TZP were similar that increased blasting pressure and erodent particle size increased surface roughness. Erosion rate increased with increasing blasting pressure, whereas it decreased with increasing erodent particle size. Particle size was the most effective parameter on changing surface topography, while the particle impact angle had no distinct effect on the erosion rate, surface roughness, and surface topography of Y‐TZP ceramics. SEM‐EDS analyses showed that the primary wear mechanism during micro blasting was micro‐cutting with a substantial amount of embedded particles on the material's surface.
