Sleep Appliances

Confidently treat snoring and sleep apnea with clinically proven Sleep Appliances!

Panthera D-SAD™


One of the smallest, lightest and most durable sleep appliances on the market.

Great Lakes is proud to introduce the Panthera D-SAD (Digital Sleep Apnea Device), an FDA approved effective treatment for snoring and obstructive sleep apnea. When worn at night, the D-SAD positions the lower jaw in a forward position, relieving snoring and mild to moderate sleep apnea conditions.
The fully CAD/CAM D-SAD is custom designed on a computer from optically scanned information, then 3D printed using the latest technology and materials. It is made from biocompatible polyamide medical grade nylon. It does not contain BPA, phthalate or resin.

Connecting rods are made of the same biocompatible polymer as the device. Unique rod connection points ensure that the device will not disengage during sleep, elongate or distort.

Panthera D-SAD™ Rx



The ultra comfortable dreamTAP appliance is designed with hardware on its exterior, offering greater tongue space with no obstructions. With more tongue space, patients experience greater comfort and a healthier sleep. Its single point of midline adjustment prevents uneven bilateral adjustment that may create an irregular bite and jaw discomfort. Stronger than surgical stainless steel, the hardware is made from nickel-free cobalt-chromium, removing the risk of an allergic reaction.

dreamTAP comes in three hook sizes for greater range of adjustment, is corrosion resistant, and utilizes custom-formed soft liners for superior retention. Adjustment mechanism advances the mandible 0.25 mm with each turn of the key. Patients can vary the position precisely by counting the turns. This allows both the dentist and the patient to confidently maintain the proper treatment position and yet allows them to make changes depending on the patient's symptoms.

Indications for use:

  • Adults weighing greater than 66 pounds
  • Patients must have at least 8 natural teeth in each arch
  • Intended to reduce or alleviate nighttime snoring and obstructive sleep apnea
  • For adult patients when sleeping at home or in a sleep laboratory
  • Single patient use only

FDA Reference #K062951

PDAC (Pricing, Data Analysis and Coding Contractor) verified for Medicare reimbursement -
Code E0486

Note:  dreamTAP can only be sold by Great Lakes to doctors in the United States.

or soft EVA material.

myTAP™ Appliance


myTAP™ is a precision-fit oral appliance intended to reduce or alleviate nighttime snoring and obstructive sleep apnea (OSA). Patients can adjust the amount of protrusion of the lower jaw to the most effective and comfortable position. “Precision-fit” technology allows for accurate molding without bite registration or lab fabrication. Made from a thermoplastic material which softens when heated, and molds to the teeth at the time of delivery. When reheated, it will return to the original tray shape, and then be re-molded to the teeth.


  • Adjustable while in the patient's mouth
  • Immediate treatment
  • Remoldable trays
  • Precision/comfortable fit
  • Freedom of movement
  • Sleek, streamlined design
  • Low cost 

Indications for use:

  • Reduce or alleviate snoring 
  • Mild to moderate obstructive sleep apnea
  • Temporary/titration device prior to prescribing a custom appliance
  • For patients 18 years and older
Contraindicated for patients who are/have:
  • Under active dental treatment
  • Have removable dentures or bridges
  • Have temporary crowns
  • Have loose teeth, crowns, or fillings
  • Have braces


 Note:  myTAP can only be sold by Great Lakes to doctors in the United States.

AM Aligner


The AM Aligner exercises the patient’s mandible comfortably back into
normal occlusion. Can be used in partnership with any sleep appliance
on the market. Heat-softening material easily conforms to dentition and
conveniently softens in a therm bath at 160°.


Note: It is recommended that the AM Aligner be adapted at the same time
the initial records are being captured to help the patient find their normal bite
position after wearing a sleep appliance.


Great Lakes appliances cannot be ordered by the general public and require a prescription. Please feel free to contact laboratory customer service for a referring provider in your area, or for additional assistance. Please be advised that Great Lakes Laboratory cannot guarantee appliance results when retention is compromised.
