Application of Vittra APS Unique as an esthetic alternative for making attachments for orthodontic aligners
Authors: Dr. Manoela Almeida and Dr. Edgard Belladonna
In the clinical examination, the professionals noted that the patient had occlusal contacts only on the third molar teeth, with occlusal instability and absence of disocclusion guides. During the anamneses, the patient reported having had orthodontic treatment with fixed braces before, for a long time, and that she would not want to do it again, but showed to be receptive to the orthodontic aligners’ technique. When informed about the need for attachments, she showed concern about their esthetics.

We chose to use the Vittra APS Unique composite, since we would be able to mask the color with its chameleon effect. The patient felt more comfortable and assured of the result.

With Vittra APS Unique composite, it was possible to camouflage the color of the dental substrate and keep the esthetic naturality of the treatment. Additionally, as the composite has just one shade which is adaptable to different shades, the process is faster and the stock is reduced. Also, it provides high resistance to wear, an important factor in orthodontics, since, in orthodontic treatments with aligners, there is great tension exerted over the attachments when the patient removes the aligners.
