Sleep Apnea Oral Appliances

The three oral appliances that Dr. Hogg most commonly uses is the TAP (Thornton Adjustable Positioner), SomnoDent and the OASYS (Oral/Nasal Airway System).

The TAP

A Unique Approach

Snoring and sleep apnea are conditions inflicted during sleep. During the night, the normal tongue and jaw positions allow air to pass through the throat effortlessly. The tongue is forward, the jaw is closed and the airway is open.

When a person suffers from sleep apnea, his/her airway is blocked periodically through the night depending on the severity of the sleep apnea. The mouth is open, the tongue and soft tissue relaxes and collapses into the throat. This causes the person to snore and possibly have sleep apnea episodes.

The TAP® is based on the same principle as cardiopulmonary resuscitation (CPR). The airway must be open to allow air to pass through the throat. A constricted or collapsed airway causes snoring or sleep apnea.

The TAP® holds the lower jaw in a forward position so that it does not fall open during the night and causes the airway to collapse. The TAP® maintains a clear airway to reduce snoring and improve breathing.

The TAP has a unique design. It allows the patient to adjust the degree to which the mandible is held forward, simultaneously allowing maximum comfort and effectiveness. It is a custom-made two-piece appliance that snaps firmly over the upper and lower teeth. The hook on the upper tray and the bar on the lower tray of the appliance engage enabling the mandible to be pulled forward. The dial mechanism (Front Assembly), found on the front of the upper tray, controls the amount the mandible is advanced (titrated). When the patient finds a comfortable, effective position, the Front Assembly can be removed from the upper tray allowing the lips to close.

The TAP has alleviated snoring in more than 96% of patients who wear the appliance, making it more successful than any other oral appliance currently available. It is the only oral appliance proven effective for the treatment of severe obstructive sleep apnea.

SomnoDent Oral Appliance
The Snoring & Sleep Apnea Treatment...
SomnoDent MAS™

What the SomnoDent MAS™ does

The SomnoDent MAS™ positions your lower jaw slightly forward of its natural position, which has the effect of tightening the soft flesh (or ‘tissue’) at the back of your throat, which prevents it from collapsing.

The patented fin-coupling mechanism on the lower arch of the SomnoMed splint ensures that your lower jaw (mandible) remains in the correct position, whether you sleep with your mouth open or closed – or open your mouth for any other reason, such as to take a drink.

This freedom to move your jaw up and down, without compromising the effectiveness of the device, is a unique feature of the SomnoDent MAS™.

A Clinically Tested Oral Device

The SomnoDent MAS™ is an oral appliance, which fits over the upper and lower teeth, much like a sports mouthguard. However unlike a sports mouthguard it is a precision-made, clinically-tested medical device.

Three Good Reasons to Choose the SomnoDent MAS™:

  1. It’s comfortable. It is the most comfortable and discreet mandibular advancement splint available.
  2. It’s effective. Its effectiveness to treat snoring and mild to moderate OSA has been clinically validated. (Note: success in all cases cannot be guaranteed.)
  3. It’s good value. Given the quality, comfort, likelihood of success, manufacturer’s warranty and long life of the appliance, it provides true value for money.

OASYS (Oral/Nasal Airway System)

The O2 OASYS Oral/Nasal Airway System® is the first dental device to address both vulnerable regions of the respiratory tract. By repositioning the mandible it holds the lower jaw forward to keep open the pharyngeal area in the back of the tongue. Acting as a nasal dilator, it decreases airway resistance so it improves ease of airflow through the nasal passage.

It is approved by the FDA (K030440) as a nasal dilator and mandibular repositioner for the treatment of snoring and sleep apnea.

The OASYS not only repositions the lower jaw forward and opens the nasal passages for better breathing, but also helps to guide the tongue forward to further enlarge the breathing opening.
