OBJECTIVE To test the hypothesis that there is no difference between the frictional forces produced by a passive self-ligating bracket (SLB) in vitro and a conventional bracket (CB) used with two types of elastomeric ligatures. MATERIALS AND METHOD The brackets, wires and ligation methods used in vitro were a passive SLB and a CB used with two types of(More)
UNLABELLED Self-ligating brackets engage the wire by means of a slide mechanism. Forces that have to be applied to open and close the sliding mechanism of brackets are still unknown. OBJECTIVE The aim of this study was to measure and compare the opening and closure forces of different self-ligating brackets. MATERIAL AND METHODS Three different(More)
