Adjustable Dorsal Appliance: A Superior Solution for Snoring and Sleep Apnea

Last updated: August 11th, 2023

The Adjustable Dorsal Appliance (ADA)

The Adjustable Dorsal Appliance (ADA) offers exceptional fit, comfort, and retention. Utilizing precision-milled upper and lower occlusal splints, it opens the vertical relationship and holds the mandible in a forward position, effectively reducing snoring and mild-to-moderate obstructive sleep apnea in adults. Its two-piece construction allows for lateral jaw movement, and the interlocking buccal inclines alleviate muscle trismus while maintaining normal jaw function during sleep. The ADA is suitable for various dentitions, making it an excellent choice for patients with existing crown and bridge work.

Patient Directions: Adjustable Dorsal Appliance

The Adjustable Dorsal Appliance is a widely used treatment for snoring and obstructive sleep apnea. Custom-made for each patient by prescription, it consists of two parts, offering comfort and lateral jaw movement. Expansion screws on the upper portion gradually move the jaw forward, supporting the lower jaw in a dentist-prescribed position while sleeping.


To ensure the best results with the Adjustable Dorsal Appliance, regular follow-up visits are crucial. Here's a recommended maintenance schedule:

  1. Week 1: Comfort Check - Make necessary adjustments for fit and positioning.
  2. Months 1, 2, and 3: Evaluate teeth and the appliance for any adjustments in jaw position.
  3. 6 months: Check progress and address concerns.
