BACKGROUND Numerous strategies have been proposed to decrease the treatment time a patient requires in orthodontic treatment. Recently, a number of device-accelerated therapies have emerged in orthodontics. Photobiomodulation is an emerging area of science that has clinical applications in a number of human biological processes. The aim of this study was to determine if photobiomodulation reduc...

background: sterilization techniques could affect the characteristics of orthodontic wires. the aim of the present study was to evaluate the effect of steam and dry heat sterilization techniques on load-defl ection behavior of fi ve types of β-titanium alloy wires. materials and methods: the samples consisted of 30 straight lengths of fi ve types of β-titanium alloy wires: titanium molybdenum a...

The aim of this investigation was to determine the influence of fluoride in certain mouthwashes on the risk of corrosion through galvanic coupling of orthodontic wires and brackets. Two titanium alloy wires, nickel-titanium (NiTi) and copper-nickel-titanium (CuNiTi), and the three most commonly used brackets, titanium (Ti), iron-chromium-nickel (FeCrNi) and cobalt-chromium (CoCr), were tested i...

This study aims at revising the biomechanical principles of the segmented archwire technique as well as describing the clinical conditions in which the rational use of scientific biomechanics is essential to optimize orthodontic treatment and reduce the side effects produced by the straight wire technique.

We report a simple, effective method of managing displaced unilateral condylar fractures with occlusal disruption using vacuum-formed thermoplastic foil splints with bonded wire cleats. The cleats enable intermaxillary fixation in the form of orthodontic elastics to be used, which guide then maintain the occlusion in centric relation. A case is presented in which this technique was used success...

background: the advantages of coated orthodontic wires such as esthetic and their effectson reduced friction, corrosion and allergic reaction and the signifi cant consequences of plaque accumulation on oral health encouraged us to assess bacterial colonization on these wires. materials and methods: a total of 18 (9 upper and 9 lower) epoxy resin coated 16 × 22 nickeltitanium wires (spectra, gac...

statement of the problem : fixed retainers were developed to maintain incisor alignments after orthodontic treatments. although the effects of fixed retainers on periodontal health are clinically studied, no studies have still evaluated the histological changes in the periodontium after the placement of thefixed retainers. purpose: the aim of this study was to evaluate the effects of customised...
