duced in the early 1970s, used conventional labial brackets that were modified by the clinician and bonded directly to the lingual surfaces. Brackets designed specifically for lingual usage1-4 were initially prone to technical problems that made them difficult to use in everyday practice. The development of indirect bonding permitted more precise lingual bracket positioning and reduced the chai...

Background- Arch expansion is one of the non- extraction methods gaining space. This study aims to assess and compare arch achieved during initial leveling alignment with three different bracket-archwire combinations.
 Material Methods- was a retrospective done in university setup. From available patient information archives, records 30 subjects based on their advocated bracket system were...

quired several archwire bends to compensate for the lingual morphology of the teeth.1 Not only did this complicate the clinical procedure, but it led to archwire breakage in the bend areas and created impediments to sliding mechanics, potentially interfering with canine retraction. A sliding jig could not be used, and it was difficult to adjust angulations for the correction of root positions. ...

AIM Compare surface roughness of 'aesthetic' nickel-titanium (NiTi) archwires with their dynamic frictional properties. METHODS Archwires investigated were: four fully coated tooth coloured [Forestadent: Biocosmetic (FB) and Titanol Cosmetic (FT); TOC Tooth Tone (TT); and Hawley Russell Coated Superelastic NiTi (HRC)]; two partially coated tooth coloured [DB Euroline Microcoated (DB) and TP A...

JCO/APRIL 2010 © 2010 JCO, Inc. C techniques for activating a closing loop are problematic. Cinching the distal end of the archwire can be time-consuming and inaccurate. Tying back an omega loop between the premolars or between the second premolar and first molar is difficult when the interbracket space is narrow. Lacing back the archwire to a hook is possible, but a crimpable hook can come loo...

objective: corrosion resistance is among the most important properties of metal alloys used in the oral cavity. consumption of acidic foods reduces the salivary ph and intensifies the corrosion of brackets and orthodontic wires. this study aimed to compare electro galvanic corrosion of different orthodontic brackets and wires and determine the amount of ions released into acidic artificial sali...

one common negative side effect of orthodontic treatment with fixed appliances is the development of incipient caries lesions around brackets, particularly in patients with poor oral hygiene. different methods have been used to prevent demineralization such as fluoride therapy and application of sealant to prevent caries. the recent effort to improve the resistance against the demineralization ...
