Overview
A Quad Helix (or quadhelix) is an orthodontic appliance for the upper teeth that is cemented in the mouth. It is attached to the molars by 2 bands and has four active helix springs that widen the arch of the mouth to make room for crowded teeth, or correct a posterior cross-bite, where lower teeth are buccal (outer) than upper teeth. A variety of this appliance is inserted into attachments that are welded to the bands. In this way the orthodontist can adjust the appliance without removing the bands.
