Abstract
ABSTRACTObjective: The aim of this study was to evaluate the attractiveness of different types of esthetic orthodontic wires by laypeople and dentists. Methods: Five different types of orthodontic wires were evaluated: three esthetic wires (Teflon-coated, epoxy resin-coated and rhodium-coated wires), and two metallic wires (stainless steel and NiTi), as control. Monocrystalline ceramic brackets were installed in the maxillary arch of a patient presenting good dental alignment. The five evaluated wires were attached to the orthodontic appliance with an esthetic silicone elastic and photographed. The photographs were evaluated by 163 individuals, 110 dentists and 53 laypeople. The data were statistically evaluated by two-way ANOVA and one-way ANOVA, followed by Tukey tests. Results: There was a statistically significant difference in the attractiveness among the wires evaluated; the most esthetic was the rhodium-coated wire, followed by the epoxy resin-coated wire and, finally, the Teflon-coated wire, with no significant difference from the stainless steel and NiTi control archwires. There was no significant difference between the groups of evaluators. Conclusion: The most attractive was the rhodium-coated wire, followed by the epoxy resin-coated wire and, finally, the least attractive wire was the Teflon-coated wire, without statistically significant difference to the stainless steel and NiTi wires, used as control.
Highlights
Esthetics is the main reason that leads most patients to seek orthodontic treatment.[1,2,3,4] The esthetic changes in smile and face achieved through orthodontic treatment have been much approached and conveyed by the media, such as television and internet
MATERIAL AND METHODS In this study, five types of 0.016-in orthodontic wires were inserted into a single esthetic orthodontic appliance at different times and photographed in the smile
Three esthetic wires were evaluated and two metallic wires were used as controls, as follows: 1. Epoxy resin-coated wire (Ever White NITI, American Orthodontics, Sheboygan, Wisconsin, USA)
Summary
Esthetics is the main reason that leads most patients to seek orthodontic treatment.[1,2,3,4] The esthetic changes in smile and face achieved through orthodontic treatment have been much approached and conveyed by the media, such as television and internet. The major manufacturers of orthodontic appliances began to worry about the esthetics in the mid1970s. For the manufacture of esthetic orthodontic accessories, the metal that was used in its bases was initially replaced by plastic polymers, which have acceptable clinical properties, even having a much lower stiffness than steel. The industry began to use polycrystalline ceramic, acrylic polymers and monocrystalline ceramic, known as sapphire, which is currently the material that provides greater esthetics in orthodontic brackets.[5,7,8]
