“…But as of writing, this study is the first to prove it on endocrowns that have a much larger thickness than those previously mentioned especially in the intra-radicular portion of the endocrown present within the pulp chamber. Scanning electron microscope images of both the tooth and the restoration surface of group A showed both surfaces covered with the bonding cement indicating an adhesive failure of the cement upon laser application, which is in accordance with Morford et al 31 findings.…”

The most common method for the removal of all-ceramic restorations is to use a highspeed handpiece with a stone or bur. Unfortunately, this process can be difficult, time-consuming and may lead to the loss of healthy tooth structures. Lasers have been suggested and used to remove ceramic orthodontic brackets, laminate veneers and full anatomical crowns.Aim: Aim of the present study was to evaluate the debonding effect of erbium, chromium-doped yttrium, scandium, gallium and garnet (ErCr:YSGG) on Computer-aided design and computer-aided manufacturing (CAD/CAM) end crown restorations. Materials and methods:Overall, 30 molar samples were prepared for this study and divided into two groups as follows:Group A-(n = 15): Endocrowns subjected to ErCr:YSGG laser application.Group B-(n = 15): Endocrowns not subjected to the laser (control). Endocrowns were fabricated from lithium disilicate ceramics and manufactured using a CAD/CAM machine. Cementation was done using Bisco Duo Link Universal™ resin cement. ErCr:YSGG laser was used with wavelength 2780 nm, 0.3J energy, 10 Hz frequency and 1000 µm tip size. Pull out test was done using a universal testing machine. Results:It was found that Non-laser group recorded statistically significant (p < 0.05) higher mean value (258.14 ± 63.43 N) for debonding than Laser group mean value (156.66 ± 32.89 N) as indicated by student t-test. Additionally, no carbonization at the dentin/cement interface was observed. Conclusion:According to the results of this study, ErCr: YSGG application can be considered a conservative method for the debonding of all ceramic endocrowns.Clinical significance: Some practitioners have been against the use of endocrown restorations due to the difficulty faced in removal and retrieval, the use of laser is an alternative, effective and conservative method.

“…Rechmann et al (13)(14)(15) applied Er:YAG laser at 10 Hz repetition rate and at the energies of 126-590 mJ (1.26 -5.9 W) for all ceramic veneers debonding. Buu et al (24) applicated an Er:YAG laser with 10 Hz, 135 mJ, pulse duration of 150 μs and 1,100 μm straight quartz fiber tip, contact mode, air spray for 2 different porcelains (lithium disilicate and leucite). Different power values were selected for debonding of all-ceramic samples in different thickness.…”

The aim of this study was to investigate the effects of different Er:YAG laser application parameters on shear bond strength values of all-ceramic restorations cemented to different tooth surfaces. Materials and Methods: Thirty lithium disilicate ceramic disc specimens (thickness of 1 mm and diameter of 3 mm) were fabricated and cemented by using a dual-cure resin cement to 30 non-carious, extracted mandibular incisors, which were divided into 2 as; tooth reduction on enamel and on dentin. Six test groups (n=5) were designed according to the application method; 1st group on enamel and without laser application, 2nd group on dentin and without laser application, 3rd group on enamel and laser applied (600mJ, 2 Hz), 4th group on dentin and laser applied (600mJ, 2 Hz), 5th group on enamel and laser applied (165mJ, 30 Hz), 6th group on dentin and laser applied (165mJ, 30 Hz). The Er:YAG laser was applied on each specimen for 3 seconds. After the laser application, all groups were subjected to shear bond strength test until fracture. The failure modes were also examined. The data were statistically analyzed by using one-way ANOVA and post hoc T-test at a 0.05 level of significance. Results: According to one-way ANOVA test, there was statistically significant differences between the groups (p<0.05). Post hoc T-test revealed no statistically significant difference only between the groups 2 and 5. The mean shear bond strength of the specimens of group 1 was statistically higher than that of all the other groups (p<0.001). Conclusion: Er:YAG laser-irradiation is a successful and effective application in removing ceramic veneers. When the depth of the tooth reduction amount increases, parameters such as; the frequency and energy of the laser application can be reduced for restorations with the same thicknesses.

“…In a recent study, we have shown that using an Er:YAG laser allows for complete debonding of porcelain veneers from extracted teeth without damage to, or removal of, the underlying healthy tooth structure. The debonding process of veneers is very efficient, with an average removal time of 100 seconds per veneer . In the rare occasion that a mishap occurred at the veneer bonding appointment, an inaccurately placed veneer might even be removed without destroying the veneer .…”
