“…The present results illustrated that laser-assisted debonding of ceramic veneers can reduce the frequency of occurrence of the debonding site at the enamel-adhesive interface and therefore reduce enamel harm. These results was in agreement with previous studies 8,9 .…”

“…The aim of the present study was to assess the Er,Cr:YSSG laser applied with selected laser parameters, as a conservative and alternative technique for veneer debonding of different thicknesses luted by total etch adhesive resin. The idea behind this method of veneer debonding came from its ancestors 'the Laser assisted debonding of ceramic brackets' that has gained a great popularity and success in clinical practice [8][9][10] .…”

“…The closer the debonding interface is to the enamel, the greater is the risk for enamel damage 8 . In the current study, higher ARI scores were seen in the laser groups (L0.5, L1) in comparison to the control groups (C0.5,C1).…”

“…Therefore, in order to eliminate the drawbacks of conventional removal method and to decrease the irreversible enamel surface harm, laser assisted veneer debonding have been suggested 1 . 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 .…”

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.

AIM: The aim of this in-vitro study was to observe and analyze the various enamel surface changes that occur due to laser debonding of metal and ceramic brackets, done by means of Er, Cr:YSGG laser. MATERIALS AND METHODS: 90 extracted premolars were randomly allocated into one of six groups with 15 teeth each. The groups represent metal brackets (Groups A1, A2, A3) and ceramic brackets (Groups B1, B2, B3). Each sub-group represents the mode of debonding used in the study. Debonded teeth were analyzed under scanning electron microscopy (SEM) at 80X and at 1000X magnification at three sites. The adhesive remnant index (ARI) scores were analyzed and the presence of enamel damage was observed. RESULT: ARI showed high score in Groups A1 and B1. SEM images of large composite remnants at the site of bracket in Groups A1 and B1 at the site of bracket and multiple enamel microcracks and fractures at interface and enamel adjacent to bracket in Groups A1 and B1. SEM images of minimal composite remnants at the site of bracket in Groups A2, A3, B2, and B3 and little to no presence of enamel microcracks or fractures at interface and enamel adjacent to bracket in Groups A2, A3, B2, and B3. CONCLUSION: The use of Er, Cr:YSGG laser in orthodontic practice, especially in the debonding procedures of orthodontic brackets provide quality care to patient with minimal post-treatment damages.

Chaque fois que nous déposons des attaches en céramique, qu’elles soient monoou polycristallines, nous sommes confrontés à des risques iatrogènes comme les fêlures, les factures, les arrachements des prismes de l’émail, les hyperhémies pulpaires ou l’ingestion et l’inhalation de bris de céramique. Le laser diode peut minimiser grandement ces risques par son effet sur l’affaiblissement de l’adhérence du composite résine dans l’interface émail-bracket sans pour autant élever la température pulpaire ni porter atteinte à la santé de la dent.
