<p>An orthodontic attachment device connects an intra-oral appliance to other orthodontic components in the oral cavity. The attachment device is particularly useful for telescoping-type interarch appliances that tend to reposition one dental arch relative to the other dental arch. The attachment device includes a first section that is non-rotatably connected to an archwire, and a second section that has an opening. The opening of the second section pivotally receives a coupler of the interarch appliance.</p> |
