“…Aluminum oxide with a particle size of 50 micrometers has been found to be the most desirable for use in sandblasting. [17][18][19][20] Sandblasting roughens the surface of all metals (including stainless steel), and as a result, increases the surface area for both chemical and mechanical bonding. 21 To our knowledge there is no research in the literature with regard to the comparison of the fracture strength of the silver soldering and laser welding with and without sandblasting of the orthodontic band-wire.…”

Aim:The aim of this study was to compare the fracture strength of orthodontic band-wire joints made by conventional silver soldering and different laser welding procedures and detect the effects of the surface preparation with sandblasting to the fracture strength of the laser welding. Materials and Methods: Forty specimens were divided to four groups (n=10); group 1; brazing with silver solder, group 2; laser welding (Desktop Compact Laser, Dentaurum,Germany) with sandblasting (with 50 μm aluminum oxide), group 3; laser welding with filling material and sandblasting, group 4; laser welding with filling material without sandblasting. The fracture strengths were measured using a universal testing machine (Lloyd Instruments plc.). Data were analyzed by ANOVA and Tukey's post hoc test (p=0.05). Results: Silver soldering showed the highest fracture strength value and it significantly differed from the laser welding groups. Although group 3 (with filling material and sandblasting) showed great strength, laser welding groups did not show any statistically significant differences between each other. Conclusions: In conclusion, silver solder showed the highest mechanical property. Laser welding with filler material and sandblasting showed sufficient strength for clinical use and can be used for the band-wire joining while orthodontic appliance fabrication.

“…The preferred size of the alumina oxide particles used, differs from report to report. 50pm grit, which cleans the surface sufficiently and does not remove too much metal, something that can affect the fit of blasted restorations, is favoured by some investigators and has been recommended by most manufacturers (Tanaka et al 1986, Ferrari et al 1987, Pegoraro and Barrack 1987, Kountouras et al 1999. Others, though, have used 150pm grit or 250pm particle size (Wiltshire 1986, el-Sherif et al 1991, Barclay and Williams 1994).…”

This Study investigated the behaviour of metal/resin laminates of dimethacrylate resins and cobalt chromium alloy (Co/Cr) when subjected to fatigue stressing by thermo-cycling and cyclical loading, after water storage. The veneering materials used were a microfine (Silux Plus) and a hybrid (ZlOO) composite, bonded to a Co/Cr alloy through an adhesive interface (Cesead opaque primer and body opaque resin). Characterisation of the two composite resins was carried out with particular attention to water sorption. Laminates were evaluated over a period up to six months, groups of ten specimens were load cycled alone (Ld) (up to 453,600 cycles at 5 Hz), thermo-cycled alone (Th) (up to 25,200 cycles between 4°C, 37°C and 60°C) load cycled and thermo-cycled (Ld/Th) (cycled as above). Following testing, laminates were assessed for their elastic modulus, examined microscopically and the adhesive interface was subjected to a dye penetration study. The microfine resin absorbed more water than the hybrid (2.88% and 1.84% by mass respectively) and lost more soluble material (0.61%, 0.19% of original mass respectively). The laminates of the different veneering resins exhibited differences in their elastic behaviour. The apparent flexural modulus of laminates made with the hybrid resin (initial; 482.3
