“…There are no studies available demonstrating whether Er: YAG laser irradiation modifies the surface of base metal alloys. 19 The extent of the superficial changes on the metal surface depends on the energy density of the laser radiation as well as on the type of irradiated metal.…”

Objective: To evaluate and compare shear bond strength of two intra oral ceramic repair systems on metal substrate and ceramic substrate and to compare among groups to assess a better ceramic repair system after acid etching and laser surface treatment. Methodology: 40 Nickel chromium and 40 feldspathic ceramic specimens were fabricated and divided into two main groups which were further subdivided into four subgroups based on the repair systems used and surface treatments, which had ten specimens each. Hydrofluoric acid and Erbium-doped Yttrium aluminium garnet laser were used as surface treatments and two intra oral repair systems used were Bisco and Angelus. Bonded specimens were stored in distilled water for 24 hours before being thermocycled at 5°C to 55°C for 300 cycles with a 30-second dwell time. The specimens were stored for an additional 7 days before being subjected to shear force in a universal testing machine with a 10KN load cell at a crosshead speed of 0.5 mm/min. The bond strength values obtained were recorded in MPa and analyzed using independent t test.

“…The silane bonding agent is a monomer with reactive organic radicals and a monovalent water‐soluble group that produces an adequate bond between the inorganic ceramic and the organic bonding agent phases 11 . In addition, silane increases the surface energy of the ceramic substrate and improves the wettability of the resin cement 12,13 …”

“…Previous studies have shown that heating silane can improve the bond strength results, 1,2,12–14 since it exposes deeper, reactive, and stable layers of silane. However, the literature is inconclusive regarding the most suitable technique for heating silane.…”

Investigate the tensile bond strength, surface morphology, and wettability of reinforced glass‐ceramic etched with high power laser at different protocols and luted to human dentin. Fifty carious‐free human molars were used in this study and distributed in five groups according to surface etching: (Control [HF10% + Silane]; Er [Er:YAG + Silane]; Sil + Er [Silane + Er:YAG]; Nd [Nd:YAG + Silane]; and Nd + Sil [Silane + Nd:YAG]). After, the tensile bond strength test was performed. Three specimens per group were used to perform the surface morphologies by using scanning electron microscopy analysis and wettability by using the sessile drop technique. Failure modes were determined. Data were analyzed with two‐way analysis of variance and Tukey tests, with α = .05. The bond strength data showed statistically significant differences among tested groups for the laser and silanization technique type (p < .001). The highest calculated bond strength values were obtained with Er (19.25 ± 3.70 MPa) followed by Sil + Er (14.11 ± 4.11 MPa), Control (9.42 ± 2.27 MPa), Nd (9.66 ± 2.02 MPa), and Nd + Sil (6.71 ± 1.88 MPa), respectively. The silane application prior to the laser irradiation showed an inferior bond strength compared to the conventional silanization technique. The surface etching using Er:YAG laser showed promissor results for the lithium disilicate.

“…The composite-ceramic bond is dependent on the adhesion of the composite resins to the ceramic surface treatment used, and these current processes are based on micromechanical and chemical bonding [16,17]. The ceramic surfaces are prepared in a variety of ways [18], such as hydrofluoric acid etching, (HF) [16,17,[19][20][21][22][23][24][25][26][27] silica coating [19], abrasion by airborne aluminum oxide particles [28], and laser irradiation [29]. These methods are used to increase surface roughness and bond strength.…”

“…Nowadays, the laser technique is becoming more popular in the dentistry field. The Er:YAG laser wavelength is 2940 nm, which corresponds to the maximum of water absorption at the invisible spectrum [18,29]. Heat treatment may accelerate the silane, resulting in a long-lasting bond that strengthens the composite-ceramic link [3,5,13,19,[27][28][29][30][31][32][33][34][35].…”

In the current study, we evaluated the effects of heat treatment (by Er:YAG or furnace) and various surface treatments on the microtensile bond strength (μTBS) of silanized lithium disilicate ceramic. Seventy lithium disilicate (IPS e. max Press; Ivoclar Vivadent) and composite resin (Tetric N-Ceram; Ivoclar Vivadent) blocks were made and distributed into seven groups (n = 10) at random: S: silanization alone; ALS: airborne particle abrasion (APA) and silanization; SC: APA modified with silica and silanization; SHT1: silanization and heat treatment by Er:YAG; SHT2: silanization and heat treatment performed in the furnace (100 °C, 1 min); HF: etching with HF; and HFS: etching with HF and silanization. Every ceramic specimen was cemented to a composite resin block after surface treatment. Cemented specimens were embedded into acrylic resin and were tested with the μTBS test. Data were analyzed using one-way ANOVA and Tamhane T2 tests (α = 0.05). The SHT1 group had the highest bond of strength compared to the other groups (27.46 MPa). The ALS group had the lowest strength of the groups (15.56 MPa). Between SHT2 and HFS (p = 1), the comparison of the mean µTBS values showed no significant differences. It was concluded that silane heat treatment increased the resin composite–ceramic bond strength; however, within the terms of μTBS, the Er:YAG laser treatment was more successful than other surface treatment applications.

Effect of Silane Heat Treatment by Laser on the Bond Strength of a Repair Composite to Feldspathic Porcelain

Abstract: Treatment with Er:YAG laser prior to silane application can be as effective as HF etching. Heat treatment of silane by CO or Er:YAG lasers does not improve the bond strength between feldspathic porcelain and composite resin.
