“…As can be observed, with respect to the results of shear strength of the two groups studied, no statistical differences between the different surface treatments were found. Since the basic composition of the specific resins for Orthodontics resembles that found in restorative resins, it was believed in this study that these could present real conditions to be used in Orthodontics, satisfying the minimum acceptable values acceptable the shear strength of orthodontic devices, which according to Reynolds (1975), should be between 4.9 MPa and 7.8 MPa (Nakamichi et al, 1983;Herion et al, 2007;Millett et al, 2009;Santos et al, 2010;Nalawade et al, 2013;Sharma et al, 2014;Caglaroglu et al).…”

Orthodontic cements have been used to enhance retention between the band and the crown, however, unfavorable properties found in many of these cements may contribute to cement failure between band and crown's surface and leading to unsuccessful application of orthodontic forces. The aim of this study was to evaluate the shear strength of the Orthobite composite (FGM) using the Single Bond adhesive system (3M). The sample consisted of 30 bovine incisors divided in 2 groups (n=15). All teeth were submitted to prophylaxes with pumice stone and etching with phosphoric acid. In Group I the Orthobite was used conventionally. Group II was similar to Group I, however, the Single Bond adhesive system was applied after conditioning. The samples were stored in distilled water in incubator at 37 ºC for 24 h and submitted to the shear strength test at a speed of 0.5 mm/minute speed. Data were submitted to the Student T test (5 %). The results (MPa) showed no statistically significant differences between the groups, regardless of surface treatment. Thus, all groups exhibited adequate adhesive bond strength for clinical use.

“…This could be due the reason that the sandblasting procedure roughens the surface of the metal, which increases the surface area available for bonding, which further increases the retention of bands. 8 A study done by Aggarwal M et al (2000) revealed that the factory micro etching of the luting surface of stainless steel bands provide almost double the band retention compared with the in -practice sandblasting of bands. 15 Dastjerdie EV et al (2010) stated that a coarse factory etched surface aided retention, while a finer in-office pattern reduced the shear peel band strength to almost half of that of factory etched band.…”

“…Sandblasting procedure introduced in the 1950s uses a high speed stream of aluminium oxide particles propelled by compressed air. 8 Sandblasting of the metal surface improve retention by roughening, thereby increasing the surface area and providing the potential for a degree of mechanical attachment. In a study by Zachrisson et al a threefold increase in composite resin to metal adhesion following treatment by sandblasting have been reported.…”

: The purpose of giving space maintainer in primary dentition is to prevent the migration of adjacent teeth, thus holding space in dental arch for succedaneous tooth to erupt. Molar band is the fundamental component of space maintainer. The retention of band to the tooth surface is important to ensure fixed appliance therapy. Several methods have been described to improve the mechanical retentive surfaces of bands including sandblasting, burs, etc. Sandblasting of the metal surfaces improves the retention by roughening, thereby increasing the surface area and improving the potential for degree of mechanical attachment. : The aim of the study was to evaluate and compare the forces require to deband preformed pre- sandblasted and preformed in-office sandblasted molar band and to determine which type is successful to ensure superior band retention. : Twenty sound permanent molars were selected and equally divided into two groups. In group I, pre sandblasted molar bands were cemented onto the molar teeth and in group II, in-office sandblasted molar bands were cemented onto the molar teeth using ReLyX U200 as luting cement in both. The cemented samples were tested for their resistance to dislodgement on Instron Universal testing machine in tensile mode. : The result showed that the debanding forces required to remove the pre-sandblasted bands were higher as compared to in-office sandblasted molar bands. : Pre-sandblasted bands resulted in greater degree of surface roughness by providing a stronger bond between the band and the tooth as compared to in-office sandblasted bands.
