“…This technique has been proposed for surface modification, such as forming a glazed surface on ceramics, etching the ceramic inner surface, or removing ceramic veneers 30-34. However, there is a little information available about the effects of laser lights on restorative materials.…”

“…In one study;33 the surface of IPS Empress 2 ceramics was analyzed by atomic force microscopy after SB, HF and laser treatments, revealing that SB had the most distinct sharp peaks among the Groups. In another study,34 the roughness of a lithium disilicate-based ceramic was examined and it was reported that Er;YAG laser-irradiated surfaces showed less roughness than air-abraded surfaces while there were no significant differences between acid etching and laser irradiation. Moreover, air abrasion increased the surface roughness of lithium disilicate-based ceramics more effectively than the other treatments.…”

PURPOSE. The purpose of this study was to evaluate whether surface treatments affect the translucency of laminate veneers with different shades and thicknesses. MATERIALS AND METHODS. A total of 224 disc-shaped ceramic veneers were prepared from A1, A3, HT (High Translucent) and HO (High Opaque) shades of IPS e.max Press (Ivoclar Vivadent) with 0.5 mm and 1.0 mm thicknesses. The ceramics were divided into four groups for surface treatments. Group C: no surface treatments; Group HF: etched with hydrofluoric acid; Group SB: sandblasted with 50-μm Al 2 O 3 ; and Group L; irradiated with an Er;YAG laser. A translucent shade of resin cement (Rely X Veneer, 3M ESPE) was chosen for cementation. The color values of the veneers were measured with a colorimeter and translucency parameter (TP) values were calculated. A three-way ANOVA with interactions for TP values was performed and Bonferroni tests were used when appropriate (α=0.05). RESULTS. There were significant interactions between the surface treatments, ceramic shades and thicknesses (P=.001). For the 0.5-mm-thick specimens there were significant differences after the SB and L treatments. There was no significant difference between the HF and C treatments for any shades or thicknesses (P>.05). For the 1-mm-thick ceramics, there was only a significant difference between the L and C treatments for the HT shade ceramics (P=.01). There were also significant differences between the SB and C treatments except not for the HO shades (P=.768). CONCLUSION. The SB and L treatments caused laminate veneers to become more opaque; however, HF treatment did not affect the TP values. When the laminate veneers were thinner, both the shade of the ceramic and the SB and laser treatments had a greater effect on the TP values. [ J Adv Prosthodont 2014;6:8-13]

“…Er:YAG lasers had conflicting results on feldspathic porcelains. Kara et al 35 and Dilber et al 38 demonstrated the efficacy of this laser at 10 W power and 20 Hz frequency for surface etching; the results showed the same level of surface modification as HF. Erdur et al 23 used Er:YAG with an output power of 1-6 W and frequency of 20 Hz and reported non-acceptable SBS; the surface roughness evaluated by electronic microscope was not acceptable as well.…”

Evaluation of Different Types of Lasers in Surface Conditioning of Porcelains: A Review Article

et al. 2017

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.

“…However, they used different power settings for the lasers and different kinds of porcelains. In the literature, Er: YAG and Nd: YAG lasers have been suggested as possible alternatives to HFA application for porcelain treatments [28][29][30].…”

Porcelain laminate veneer conditioning for orthodontic bonding: SEM-EDX analysis

The purpose of this in vitro study was to evaluate and compare the effects of different surface treatments and laser irradiation on the bond strength of brackets bonded to porcelain laminate veneer. Porcelain laminate veneer specimens were embedded in the centers of acrylic resin blocks. Thirty-nine teeth were used for shear bond strength testing and the remaining three (one tooth for each group) were used for evaluation of the debonded bracket interface. Specimens were randomly divided into three groups, each containing 13 specimens. The details of the groups are as follows: Group SB, sandblasting with alumina particles (50 μm); Group HFA, 9.6 % hydrofluoric acid etching; Group ER, erbium-doped yttrium-aluminum-garnet (Er: YAG) irradiation (from 1 mm distance, 2 W, 10 Hz for 10 s). After conditioning, the upper central brackets were bonded to the porcelain surfaces. Porcelain laminate veneers were examined under stereomicroscope for adhesive remnant index and surface damage after debonding. The highest shear bond strength values were obtained with Group HFA (10.8 ± 3.8 MPa) and Group ER (9.3 ± 1.5 MPa), whereas Group SB revealed the lowest values. Scanning electron microscopy energy-dispersive X-ray (SEM-EDX) analysis revealed that the silicon level in the porcelain decreased after debonding in all groups. The sandblasting method did not demonstrate any ideal bond strength values; however, the 9.6 % hydrofluoric acid etching and Er: YAG laser did. There were no significant differences among all groups in terms of laminate surface damages. The Er: YAG laser therefore can be selected for ideal bond strength and minimal damage to porcelain laminates.
