| Popis: | This study examined the effect of sandblasting, in vitro, on the bond strength and survival time of first molar orthodontic bands. Survival time was assessed following simulated mechanical fatigue in a ball mill. The amount of cement left attached to the band after debanding was also assessed. In addition, the effect of sandblasting on the failure rate of 320 first molar bands cemented in 107 patients was examined in a half-mouth trail. Ketac-cem®, mixed according, to manufacturers' instructions was used as the luting agent for both laboratory and clinical trails.In vitro, sandblasting increased bond strength by 27 per cent (P |
