Introduction: The Damon system recommended the use of revolutionary, hightechnology Damon edgewise 0.019” x 0.025” orthodontic stainless steel archwires (OSSA) for major mechanics and finishing and claimed that this new archwires offer greater efficiency during orthodontic treatment. No study has been carried out to compare this relatively new archwires to other popular OSSA already in the mark...

INTRODUCTION The purpose of this study was to compare the frictional force (FF) generated by various combinations of self-ligating bracket (SLB) types, archwire sizes, and alloy types, and the amount of displacement during the initial leveling phase of orthodontic treatment, by using a custom-designed typodont system. METHODS Two passive SLBs (Damon 2 [D2] and Damon 3 [D3]), and 3 active SLBs...

OBJECTIVE The aim of this study was to compare the longitudinal stability of the conventional straight-wire system after the use of a quad-helix appliance with Damon self-ligating system in patients with Class I malocclusion. METHODS 27 adolescent patients were evaluated at three different periods: pre-treatment (T1), post-treatment (T2) and three years post-treatment (T3). Group 1 included 1...

The aim of this in vitro study was to investigate the frictional characteristics of two types of self-ligating brackets ('A' Company Damon SL and Adenta Time brackets) and two types of pre-adjusted edgewise brackets (TP Tip-Edge and 'A' Company Standard Twin brackets). The test brackets were glued to steel bars and aligned using a preformed jig. Five combinations of archwire size and material w...

OBJECTIVE To test the frictional resistance forces (FRS) generated between several archwires and (1) interactive self-ligating (ISL) brackets and (2) conventionally ligated (CL) brackets. MATERIALS AND METHODS Frictional forces produced between three different archwire combinations and self-ligating (SL) brackets (ceramic and metal-slot or all-metal) and CL brackets (metal or ceramic) were ev...

The purpose of this study was to compare the activation and deactivation forces generated during first-order archwire deflections when different sizes and types of NiTi wires are paired with conventional and self-ligating brackets (SLBs) and to evaluate the rotational control between these same archwire and bracket combinations. Four maxillary premolar SLBs (Damon 3MX, SmartClip, Carriere, and ...

AIMS To measure the friction force generated during sliding mechanics with conventional, self-ligating (Damon 3 mx, Smart Clip, and Time 3) and low-friction (Synergy) brackets using different archwire diameters and ligating systems in the presence of apical and buccal malalignments of the canine. METHODS An experimental setup reproducing the right buccal segment of the maxillary arch was desi...

The aim of this in vitro study was to evaluate the frictional forces between bracket and archwire that included three passive self-ligating brackets (Damon SL2 SDS). The brackets were individually bonded to a brass mount using a preformed 0.021 x 0.025 inch stainless steel wire jig in order to exclude adverse tipping or torsion. The central bracket was positioned 1 mm higher than the others, in...

INTRODUCTION In this prospective clinical study, we assessed the relative speed of archwire changes, comparing self-ligating brackets with conventional elastomeric ligation methods, and further assessed this in relation to the stage of orthodontic treatment represented by different wire sizes and types. METHODS The time taken to remove and ligate archwires for 131 consecutive patients treated...
