A female patient came to the private clinic reporting a dissatisfaction with the smile, especially due to the right upper lateral incisive tooth, which frequently appeared darker in photographs. She reported having worn fixed braces a few years before.
At the clinical exam, it was noted that element 12 did not show color alteration but because it was more palatine in relation to the adjacent teeth, it received less light, generating the sensation of being darker.
When proposing the orthodontic treatment for correction, the patient reported not being willing to do it but agreed when we suggested the use of invisible aligners for their being more comfortable and aesthetic. The patient showed some preoccupation with the aesthetic interference of the attachments (devices made in composite to help the dental movement). Due to that, we presented the Vittra APS Unique composite, which is capable of mimicking the color of the tooth in a very natural way, which made the patient much more tranquil and confident with the treatment.

The Vittra APS Unique composite (FGM) has proved to be an excellent alternative for the making of orthodontic attachments. Besides very interesting aesthetics (it became practically imperceptible socially), it shows satisfactory mechanical resistance, a primordial fact since it undergoes concentrated forces from the aligners during the treatment which are intensified at their removal.
