“…7,8,20 The optimal laser power settings for a majority of ceramic restorations/appliances have been reported in the range of 4.0 to 5.5 Watt. 8,12,20,41,47,48 It appears that the time required to debond ceramic restorations correlates to the volume of the luting cement, 49 the size of the abutment surface area, 48 thickness and characteristics of the restorative materials, 6,38,42,48 and chemical composition of the luting cement. 37 In general, it takes longer to debond zirconia than lithium disilicate crowns from either natural teeth or implant abutments.…”

“…[6][7][8] Removing all-ceramic restorations or orthodontic brackets from natural teeth can also be challenging due to the similarity between the color of the cement and underlying tooth structure. 9,10 The use of erbium lasers has been explored as an alternative method for debonding of ceramic appliances from natural teeth and implants, 2,[11][12][13] including removal of translucent restorative materials such as composite restorations, 14,15 fiber reinforced composite posts, 16 veneers, [11][12][13] and orthodontic brackets. 10,[17][18][19] The light emitted by erbium lasers, such as Erbium, Chromium-doped Yttrium Scandium Gallium Garnet (Er,Cr:YSGG) and Erbium-doped Yttrium Aluminum Garnet (Er:YAG) lasers carrying wavelengths of 2780 nm and 2940 nm, respectively, can be transmitted through the translucent ceramic materials and selectively absorbed by water molecules and residual monomers in luting cements, thus resulting in the vaporization of these molecules and debonding of the cement.…”

Purpose Removal of ceramic restorations and appliances can be time consuming, invasive, and inconvenient. Erbium lasers offer an alternative noninvasive method for debonding of ceramic appliances. This paper aims to provide a comprehensive review of current literature on the effectiveness of erbium lasers for removal of ceramic restorations and appliances from natural teeth and dental implants. Methods A comprehensive search of 7 databases, including Medline (Ovid), Embase, Dentistry and Oral Sciences Source (DOSS), Web of Science, Cochrane Library, and ProQuest Dissertations and Theses was performed. The inclusion and exclusion criteria were agreed prior to the literature search. Two reviewers independently screened the title and abstract. A third reviewer then broke the tie, if any. The selected articles then underwent full text review and the data was extracted. Results The search identified 4117 unique articles published through June 10, 2021. Studies were assessed and categorized based on the type of restoration/appliance, type of abutment, type of laser, laser settings, efficacy of debonding, and pulpal temperature rise. Thirty‐eight full‐text articles were reviewed for inclusion. Time for ceramic debonding varies depending on the type of restorations and materials. Removal of zirconia crowns from teeth and implant abutments requires a longer period of time compared to lithium disilicate crowns. Temperature increases were reported as 5.5 degrees or less. Laser setting and laser type affect the debonding time and the increase in temperature. Examinations of debonded ceramics demonstrated no known structural damages resulting from laser applications. Conclusions Erbium lasers are effective noninvasive tools to remove all ceramic restorations/appliances from natural teeth and implant abutments without causing harm to abutments. Laser‐assisted debonding should be considered as a viable alternative to rotary instrumentation for ceramic crowns; however, clinical studies of erbium‐assisted ceramic retrieval are needed.

“…This new technique of veneer debonding was inspired by its practice on orthodontic ceramic brackets that began in early 1990s 4 and which its success was evidenced by several studies 8,9 . There are various laser sources that have been used for this purpose such as the Nd:YAG 10 , Er:YAG 9 , Er,Cr:YSGG 8 and CO 2 11 lasers, but most researchers agree that for debonding aims, the Er:YAG and Er,Cr:YSGG lasers yield better results than other laser system 12,13 . Calabro et al 14 (2019) in their case report stated that the Er:YAG laser assisted debonding of 11 ceramic laminates compared to the conventional removal method, was more efficient and comfortable both to the patient and the dentist, less time consuming and with preservation of the remaining tooth structure.…”

Aims: To verify the efficacy of Er,Cr:YSGG laser for debonding of lithium disilicate (LD) reinforced glass ceramic veneers of different thicknesses. Methods: Forty bovine teeth were prepared and randomly divided into four groups (n=10/group) according to the ceramic disc thickness: C0.5 (Control group) and L0.5 (Laser irradiated group) in which LD discs had a thickness of 0.5mm and 5mm diameter; C1 and L1 in which LD discs had a thickness of 1mm and 5mm diameter. The lithium disilcate discs (IPS E.max®, shade HTA2) were fabricated following the manufacturer’s recommendations and cemented to the prepared tooth surface. The Er,Cr:YSGG laser was applied to the laser groups at 2.5W and 25Hz for 60seconds. Universal testing machine was used to evaluate the shear bond strength for all samples at a cross head speed of 1mm/min in an inciso-gingival direction parallel to the sample surface. After debonding, the samples were examined under stereoscope to evaluate the mode of failure according to the adhesive remnant index (ARI). Results: Laser irradiation significantly diminishes the shear bond strength from 10.868 MPa to 3.778 MPa for C0.5 and L0.5 groups respectively (p=0.00) and from 14.711 MPa to 4.992 MPa for C1 and L1 groups respectively (p=0.00). The shear bond strength required for debonding increased with increasing thickness of discs, but without significant difference (p=0.110). Higher ARI scores were seen in the laser groups (more cement remaining adhered to the tooth) when compared to the control groups. Conclusions: The Er,Cr:YSGG laser could be an effective and useful tool in debonding of lithium disilicate ceramic veneers as it decreases the shear bond strength required for veneer debonding.

“…O estudo de Albalkhi et al (8) observou que os padrões de fratura predominantes foram adesiva e coesiva, já Giraldo-Cifuentes et al (34) utilizaram o laser Er,Cr:YSGG e constataram que o padrão de fratura foi predominantemente adesivo. Em nosso trabalho nos grupos com irradiação a laser de 3 W de potência média, as fraturas foram predominantemente do tipo adesiva, nos grupos com irradiação a laser de 3,5W as fraturas foram predominantemente do tipo coesiva.…”
