The key to flexTAP’s broad appeal is the new patented Vertex Technology, which is the design of the post angulation in the flexTAP hardware.

flexTAP is the first custom oral appliance to include a standard nasal breathing component, the flexTAP Mouth Shield, to improve comfort and treatment outcomes.

Vertex Technology® is the key to flexTAP Appeal and Comfort

Vertex Technology is the design of the post angulation in the flexTAP hardware.

The post is angled at a 45-degree angle, allowing the patient to advance their lower jaw both vertically and horizontally at the same time.

By opening the oral cavity both vertically and horizontally, vs just horizontally in most oral appliances, we’ve seen patients needing less protrusion which eases joint pain or strain on the jaw and less tooth movement.

flexTAP opens the oral cavity more than any custom TAP on the market and still allows patients to self-adjust if needed.

Adjustment Mechanism

The flexTAP Adjustment Dial allows the clinician or patient to adjust the amount of protrusion of the lower jaw to the most effective and comfortable position. Each half turn (counterclockwise “from user’s perspective”) of the flexTAP® Adjustment Dial will advance in ⅓ mm increments.

ThermAcryl Liner

flexTAP is made with a patented ThermAcryl liner that is thinner and more durable. The lining is unique because it can be slightly reheated and remolded as needed to achieve the most comfortable fit while maintaining retention.

Nasal Breathing

flexTAP is the first custom appliance on the market to include a standard nasal breathing component. Recent literature shows nasal breathing as the proper way to breathe. The flexTAP Mouth Shield slips onto the post to increase comfort and provide better treatment outcomes. It also helps prevent dry mouth or excess saliva.

The New Custom flexTAP® Sleep Appliance

General Requirements


  • Accurate impressions with any type of impression material are acceptable
  • Impressions must adequately reflect all relevant anatomy
  • Impression material must not be separating from the impression tray
  • Consider pouring your models right away if your impressions are moisture, temperature, or time sensitive
  • Impressions sensitive to moisture content should be wrapped in a damp paper towel and placed in a sealed plastic bag if models are not poured immediately
  • Only metal impression trays and those with VPS impression material will be returned
  • The nature of impression materials currently on the market may contribute to common model problems encountered in the laboratory. Have you encountered porosity (bubbles, voids) or poor surface quality? Plaster or stone mixes are water based and they interact with impression surfaces in a water-like manner. Liquids placed on solid surfaces will be either attracted to, or repelled from that surface in varying degrees. Please be aware when selecting impression material if it is hydrophilic or hydrophobic.

Hydrophilic: is attracted to, or can be wetted by water.
Hydrophobic: is when liquid is repelled or fails to bond with liquids.
Vinyl poly siloxane (VPS) options can be hydrophilic or hydrophobic. Alginate is hydrophilic.

  • There are advantages and disadvantages to these impression options but there are products on the market to help reduce the disadvantages. Surfactants and debubblizer sprays can be used to lower surface tension between surfaces making the impression material more hydrophilic and assure a better impression result.
  • Great Lakes carries ACU-flow™ a VPS impression material which is hydrophilic and requires NO surfactant spray for surface tension reduction, eliminating bubble formation. Surfactants must be used properly and excess surfactant should not be allowed to pool in the cusp tips. This can cause loose, sandy-like cusp tips. Excess surfactant needs to be blown out leaving a wet look only before pouring. 

Learn how to take a reliable impression


  • Plaster or stone models are acceptable. Generally, the durability of stone is preferred.
  • Models should be reasonably trimmed, yet sufficiently thick for strength considerations.
  • No horseshoe-shaped models; Models should have a base of at least 7mm in the thinnest area.
  • Bases will be added as necessary (for an additional fee) to models without bases or those lacking adequate base thickness or strength.
  • Please indicate if your model must be duplicated as work models may get damaged during the appliance fabrication process.

Bite Records:

  • Please package bite registrations carefully.
  • Bite records must not be left between models for shipment to the lab.
  • Dedicated packaging should be considered for brittle materials such as Delar wax.
  • Please identify the nature and the intent of each bite record, if more than one is being supplied.
  • Please consider mounting the maxillary model, before sending it to the lab, for those cases requiring mounting. Sending items such as facebows, bite forks, and mounting jigs through the mail often results in unreliable mountings.
