Sagittal Appliance

The Sagittal appliance is used to lengthen the arch by distalizing the molars or driving the anterior section forward. This appliance is often used to alleviate crowding. We install expansion screws along the sagittal plane and parallel to the left and right side. You can also add a screw to either side. As with any expansion appliance, we recommend maximum retention with Adams clasps on the 6’s (if erupted) and ball clasps between the pre-molars. You can also incorporate a labial bow to control the anterior incisors and a posterior bite plate to disarticulate the arches providing additional anchorage for the upper appliance.
