Many options are available on the market of esthetic orthodontic appliances, among which lingual appliances, aligners and ceramic brackets are highlighted. The latter are the most popular due to following the same principle of buccally positioned metallic brackets; however, patients wearing them are frustrated when they find out the orthodontic wire inserted into the slot is a metallic one. With a view to solving such an issue, the industry of orthodontic material developed esthetic orthodontic wires. They are presented in pre-contoured archwire shape and coated with enamel-like color material which aims at disguising the wire. Nevertheless, some doubt is cast on whether this type of archwire is effective. With a view to proving the effectiveness of esthetic orthodontic wires, American researchers conducted a study1 to compare the physical properties of NiTi conventional and coated wires. They concluded that some coated esthetic archwires had the same physical properties of NiTi conventional ones. Despite such conclusion, further development is necessary, given the lack of esthetic wires that can be bended while preserving esthetics.
