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. 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

4. Comparison of deflection forces of esthetic archwires combined with ceramic brackets
Abstract Coated archwires and ceramic brackets have been developed to improve facial esthetics during orthodontic treatment. However, their mechanical behavior has been shown to be different from metallic archwires and brackets. Therefore, the aim of this study was to compare the deflection forces in coated nickel-titanium (NiTi) and esthetic archwires combi

5. Effect of different enamel conditionings on the bond strength of glass ionomer cement and ceramic brackets
Aim: To evaluate the effect of different enamel conditionings on the shear bond strength (SBS) and bond failure patterns of a resin modified glass ionomer cement (RMGIC) used to bond ceramic brackets. Methods: 105 human premolars extracted for orthodontic reasons were divided into 7 groups according to the enamel surface treatments: conditioners (35% phospho

6. Staining of esthetic brackets by plaque disclosing solutions
AIM: To evaluate the staining of esthetic orthodontic brackets by plaque disclosing solutions. METHODS: Two types of brackets manufactured by GAC/DENTSPLY(r) were evaluated: ceramic (n=30) and polycarbonate (n=30). The brackets were divided into 6 groups. Two control groups (n=6) were immersed in absolute ethanol: GI - ceramic brackets and GII - polyca

7. CO2 laser-assisted debonding for esthetic ceramic brackets / Laser de CO2 como auxiliar na remoção de bráquetes estéticos cerâmicos
This study evaluates the efficacy CO2 10,6 m laser-assisted debonding esthetic ceramic brackets. For this purpose it was used 105 recently extracted lower human premolars that were irradiated with CO2 laser before debonding. In the first phase, the objectives were to measure and compare the temperature in composite for bracket bonding and at the pulp chamber

8. Effect of bonding material, etching time and silane on the bond strength of metallic orthodontic brackets to ceramic
O objetivo neste estudo foi avaliar a resistência de união de bráquetes a cerâmica feldspática com diferentes tempos de condicionamento ácido, materiais de união, com ou sem aplicação do silano. Cilindros de cerâmica feldspática foram condicionados com ácido fluorídrico 10% por 20 ou 60 s. Para cada tempo de condicionamento, metade dos cilindros

9. Evaluation of dental enamel before and after fixing and removal of orthodontic brackets ortodônticos / Avaliação do esmalte dentário antes e após a colagem e descolagem de braquetes ortodônticos
The objective of this study was to evaluate the quantity of residual resin after removal of brackets and the loss and//or wear-and-tear of enamel occurring during the phases of fixing, detaching and removal of remnant resin in the bracket area and its adjacent. The sample was made up of 150 premolars, divided into two groups in accordance with the type of br

10. Avalição in vitroda resistência ao cisalhamento de braquetes colados em diferentes sistemas cerâmicos / In vitro short-term evaluation of shear strength of brackets bonded to different porcelain systems
Orthodontic treatment in the adult population has lately gained popularity in an attempt to improve esthetic and function. It is, however, a common feature in these patients, that their dentition is restored by resin veneers, porcelain fused to metal and all ceramic crowns. In this context, the orthodontist faces the challenge of bonding brackets to differen
