Orthodontics use clear aligner systems like Invisalign to straighten teeth. The digital set up often involves "attachments" placed on the teeth surfaces. These "bumps" act like clips and provide pressure surfaces for the aligners to be effective. They are quite small in most cases and require minimal maintenance. There is a library of different attachments with 3D controls that allows your orthodontist to design an orthodontic plan for your teeth and smile.
