Abstract
The present disclosure provides self-ligating orthodontic brackets with improved control over access to the archwire slot. Access to the archwire slot is controlled by a latch assembly featuring a door rotatable about an axis relative to the bracket body and a lock positioned near the axis to prevent inadvertent rotation of the door. The lock engages a surface of the door and is capable of preventing undesired rotation between an open state, where an archwire is insertable into the archwire slot, and a closed state, where access to the slot is prohibited. The self-ligating brackets may also include a biasing spring to provide active ligation and further inhibit undesired rotation of the door.
