Sleep Apnea Product Guide

Obstructive sleep apnea is a pervasive medical disorder that prevents airflow during sleep and is associated with several life-threatening conditions. Many patients with mild-to-moderate OSA (obstructive sleep apnea) are seeking alternatives to CPAP devices.

We use digital workflows and industry-leading materials at Dandy to produce two highly accurate and effective sleep apnea and anti-snoring devices:

  1. The Herbst Appliance
  2. The Dorsal Appliance

The fundamental difference between these devices is explained below.

Check out our Sleep Apnea Appliance Pricing and Turnaround Times article for more pricing and turnaround times details. 

Herbst Appliance

The adjustable Herbst is a one-piece construction held together by two adjustment mechanisms on the buccal or outer area of the upper and lower appliance. The adjustment mechanisms are designed for the doctor to advance the mandible to the desired position incrementally. This appliance is desirable for a patient who wants minimal acrylic to preserve tongue space and would like the adjustment capability. 

  • Pros:
    • Covered by Medicare

    • Allows for lateral and vertical movement

    • Easily adjustable

Herbst: FDA and Medicare Approval: 510(k) clearance and Class II FDA approval. 

Premarket Submission Number: K103076
Registered Establishment Number: 1937100
Regulation Number: 872.5570
Product Code: LRK

Dorsal Appliance

The Dorsal is a two-piece design with separate upper and lower acrylic portions that, when engaged, position the mandible into a protrusive position via acrylic fins built in the lower acrylic portion. The Dorsal is an adjustable design utilizing advancement screws on the upper acrylic portion. The screws allow the doctor the ability to adjust the mandible to the most desirable position. The separate two-piece construction is for patients who want a greater range of motion and lateral excursion. 

  • Pros:
    • Allow for most normal mouth movement

    • Two-part design with no metal hinge for comfort

Dorsal: FDA and Medicare Approval: 510(k) clearance and Class II FDA approval.
