Summary

The objective is to compare the dento-alveolar therapeutic effects of wearing class II inter-arch traction elastics on aligners versus multi-brackets in an adult population. The principal hypothesis is no significant difference in therapeutic effects of using inter-arch elastics on aligners versus multi-brackets.

Detailed description

It is a non-interventional research involving the human person, research on existing data and / samples in the field of dentofacial orthopedics. This study analyzes the effects of rubber bands when combined with aligners in adult patients. This is a comparative retrospective study of radiographs and casts before and after orthodontic treatment. The patients studied are in Angle class II and adults. Two groups are analysed: patients treated with fixed (vestibular multi-attachment) and removable (Invisalign-type aligners) appliances.
