Upper sagittal with posterior acrylic

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.

 

Description

Treatment & Care

Activation of the screw is 1-2 times per week.

Patients should wear 22 hours a day and clean daily with toothpaste to prevent the buildup of plaque and odor. Avoid Efferdent and other effervescent solutions, as it may erode components on the appliance. It is recommended to use products like DentaSoak
or Retainer Splash.
