Oventus Sleep Appliances

Introducing an innovative approach to oral appliance therapy – a treatment platform featuring Oventus Airway Technology. With a unique, low resistance airway incorporated into its patented design, the O2Vent™ customized oral appliances deliver air to the back of the mouth, allowing for breathing through the appliance, bypassing nasal resistance and velopharyngeal obstruction.

O2Vent Products Are a Breath of Fresh Air


O2Vent™ W

The latest device in the range. The “W” is a slimline winged-style device that uses a dual mechanism to stabilize the jaw and move it forward without locking the upper and lower jaw together.


O2Vent™ T

The “T” device connects at the front before you insert into your mouth. You can titrate your lower jaw forward to a comfortable range that further opens your airway.


How Oventus Airway Technology Works


Nose breathing during sleep is ideal and patients should breathe though their nose to the extent they can. In the case of nasal resistance, nasal obstruction or soft palate collapse, a patient would normally experience a respiratory event or arousal and may then convert to mouth breathing, leading to an unstable airway. Oventus Airway Technology is designed to allow continued air flow to the oropharynx
in the presence of nasal or soft palate obstruction. If device breathing is required during sleep, an oral seal is maintained and
ventilation normalizes.



If there is reduced flow through the nasal airway or a soft palate obstruction occurs, air can be drawn into the front of the device while the lips maintain an oral seal around the device extension.


Air passes through to the back of the device in an enclosed, low resistance pathway.


The device advances the lower mandible to stabilize jaw position, bringing the tongue forward and opening the airway.

Taking Impressions – Bite Recording



For the best device results, MicroDental recommends you take an impression based on Oventus’ guidelines shown here. This will directly impact the precision and fit of the device, along with the comfort of the bite – making it a very important part of the fabrication process.

Many O2Vent™ Patients Snore a Lot Less,
Most Snore No More

Oventus Clinical Trial results show that…


100% of patients experienced significant improvement in snoring using the O2Vent™


82% of patients experienced complete elimination of snoring using O2Vent™


76% of patients decreased their Apnea-Hypopnea Index (AHI) by more than 50%**
