“…[27][28][29] The use of laser energy in zirconia-surface treatment was a subject of interest for researchers. [30][31][32][33] With the objectives of enhancing bonding potential by creating Cr:YSGG laser at 3 W in the present study resulted in a change of the zirconia surface with a significant roughness increase, while cell growth and proliferation were significantly lower than the AS and the SIE groups, which is in accordance with other published papers. 34,35 This may be due to the surface topography created by the laser energy and the zirconia absorbing capacity of the wavelength.…”

Aim:The aim of this study was to characterize the surface of zirconia subjected to different treatments and evaluate its effect on cell adhesion and proliferation. Materials and methods:A total of 80 zirconia disks were divided into four groups (n = 20) according to the surface treatments used: group I: as-sintered (AS), no surface treatment applied; group II: abrasion treatment applied using Rocatec (ROC; 3M ESPE) system with silica-coated alumina powder of grit size 110 μm; group III: erbium, chromium:yttrium, scandium, gallium, garnet (Er, Cr:YSGG) laser (LAS; BIOLASE) was used at a frequency of 20 Hz and output power of 3 W; and group IV: specimens were subjected to the selective infiltration etching (SIE) technique. Surface characterization was evaluated for the different groups (roughness, hardness, and morphology), and cell behavior (adhesion and proliferation) was tested (α = 0.05). Results:The ROC group reported a significant increase in surface roughness (2.201 ± 0.352) and Vickers hardness (1758 ± 16.6) compared with the other surface treatments. The SIE surface-treated group reported a significantly higher number of cells (64.5 ± 2.6 and 53.5 ± 2.2 respectively) compared with the other surface-treated groups. Conclusion:The SIE is a promising surface treatment for zirconia that significantly enhances cell adhesion and osseointegration.Clinical significance: The SIE treatment of zirconia implants may help in a faster and better osseointegration.

“…However, the negative influence of air-abrasion has also been reported (Guess et al, 2010), such as the tetragonal to monoclinic phase (T-M) transformation in surface crystalline structure, as well as the formation of surface flaws which could lead to decrease in the reliability of zirconia framework. Therefore, alternative methods of zirconia surface modification have been developed for the cementation with resin adhesives, including selective infiltration etching, surface coating, laser irradiation, etc (Liu et al, 2013). Most of the methods were claimed to increase resin zirconia adhesion at different levels.…”

“…Once the adjustment procedures are finished, the regeneration firing might induce reverse transformation (m→t), returning the Y-TZP to a metastable tetragonal phase zirconia that, although less resistant, is more stable 15) . This heat treatment has already been studied, but still deserves attention because of the disagreement between protocols suggested by different authors and due to microstructural characterization after regeneration firing that has not been fully understood yet [18][19][20] . Thus, this study focused on analyzing Y-TZP microstructure after grinding and annealing (regeneration firing) in more detail in order to characterize the material's crystalline phases and draw initial conclusions regarding the interaction among its different phases.…”

This study evaluated microstructural and crystallographic phase changes after grinding (G) and regeneration firing/anneling (R) of Y-TZP ceramics. Thirty five bars (Lava TM and Ice Zirkon) were divided: Y-TZP pre-sintered, control (C), regeneration firing (R), dry grinding (DG), dry grinding+regeneration firing (DGR), wet grinding (WG) and wet grinding+regeneration firing (WGR). Grinding was conducted using a diamond bur and annealing at 1,000°C. The microstructure was analyzed by SEM and the crystalline phases by X-ray diffraction (XRD). XRD showed that pre-sintered specimens contained tetragonal and monoclinic phases, while groups C and R showed tetragonal, cubic and monoclinic phases. After grinding, the cubic phase was eliminated in all groups. Annealing (DGR and WGR) resulted in only tetragonal phase. SEM showed semi-circular cracks after grinding and homogenization of particles after annealing. After grinding, surfaces show tetragonal and monoclinic phases and R can be assumed to be necessary prior to porcelain layering when grinding is performed.
