2. A comparative analysis of the frictional resistance of esthetic orthodontic wires
Resumo Introdução O movimento ortodôntico bem sucedido está diretamente relacionado com a capacidade de os fios ortodônticos deslizarem sobre os bráquetes e tubos ortodônticos. Portanto, durante a movimentação ortodôntica a principal preocupação está diretamente ligada a fricção entre o suporte e o fio. Objetivo O objetivo deste estudo foi a

3. Influence of heat treatment on the mechanical properties of CrNi stainless steel orthodontic wires
RESUMO Introdução: o tratamento térmico de fios de aço inoxidável é um procedimento clínico rotineiro adotado por muitos cirurgiões-dentistas para aliviar o estresse causado após a confecção de dobras no fio. O presente estudo avaliou a influência do tratamento térmico em fios de aço inoxidável com secção retangular de 0,016’’ x 0,022�

4. Do laypersons perceive aesthetic differences between coated and uncoated orthodontic archwires?
RESUMO Introdução: rotineiramente na terapia ortodôntica fixa, utilizam-se braquetes estéticos combinados com fios metálicos, principalmente devido a algumas desvantagens no uso clínico dos fios estéticos. A percepção estética dos leigos nessa situação precisa ser explorada na literatura. Objetivo: o objetivo deste estudo transversal foi aval

5. Accuracy of linear measurements performed with two imaging software in cone-beam computed tomography scans of dry human mandibles
ABSTRACT The present study aimed to assess the accuracy of linear measurements performed with two software packages in multislice (MSCT) and cone beam (CBCT) computed tomography (CT) images. The sample consisted of 10 human mandibles marked standardly 8 times with metallic orthodontic wires. The mandibles underwent both MSCT and CBCT scanning and were measur

6. Characterization and coating stability evaluation of nickel-titanium orthodontic esthetic wires: an in vivo study
Abstract The objective of this study was to compare coating dimensions and surface characteristics of two different esthetic covered nickel-titanium orthodontic rectangular archwires, as-received from the manufacturer and after oral exposure. The study was designed for comparative purposes. Both archwires, as-received from the manufacturer, were observed usi

7. Evaluation of deflection forces of orthodontic wires with different ligation types
Abstract The aim of this study was to evaluate deflection forces of orthodontic wires of different alloys engaged into conventional brackets using several ligation types. Stainless steel, conventional superelastic nickel-titanium and thermally activated nickel-titanium archwires tied into conventional brackets by a ring-shaped elastomeric ligature (RSEL), a

8. Deflection and Flexural Strength Effects on the Roughness of Aesthetic-Coated Orthodontic Wires
Resumo O objetivo foi avaliar a resistência a flexão e os efeitos da deflexão na rugosidade de superfície de fios ortodônticos estéticos. A amostra foi composta por 70 segmentos de fios NiTi calibre 0,014 polegadas: revestidos por politetrafluoretileno (PTFE) (Titanol Cosmetic-TC, Flexy Super Elastic Esthetic-FSE, Aesthetic Nickel Titanium Wire-ANT); r

11. Mechanical Performance of Nickel-titanium Archwires
The purpose of the present work is to compare the mechanical properties of commercially available NiTi orthodontic archwires lots. Superelastic (SE) and heat-activated (HA) NiTi archwires from two lots of six manufacturers (3M, GAC, Tp, Orthosource, Orthometric and Morelli) were partitioned into eleven groups (n=132) and tested under three-point bending test

12. Analysis of mesiodistal angulations of preadjusted brackets
Manufacturers offer various prescriptions of preadjusted brackets for use in the “straight-wire” orthodontic technique. However, the need to incorporate bends in the rectangular wires during orthodontic finishing has led to concerns regarding the type of prescription chosen and the credibility of information provided by the manufacturer. The aim of this
