Most mandibular appliances improve the shape of the upper airway to prevent collapse by bringing the jaw and tongue forward.
However, patients may have varying and/or multiple levels of obstruction in the upper airway such as tongue, soft palate and lateral wall collapse.
While these appliances are limited to those aforementioned areas of collapse, there is a common and important missing contributor to facilitate more effective treatment.
The missing contributors are nasal issues. These include nasal congestion, resistance and anatomical factors all of which promote mouth breathing. The OADS O₂Vent® device with its patented airway management technology, allows air to flow through the device to the back of the throat. This technology addresses all areas of collapse including the nose, allowing uninterrupted airflow and increasing treatment outcomes.
The OADS O₂Vent® device incorporates a unique patented airway technology directly into the appliance. This airway enables an uninterrupted flow of air even in the presence of nasal obstruction, therefore ensuring the patient has efficient and effective therapy.
No. Patients will breathe through their nose to the extent they can, and when they can't, they mouth breathe. This is because as nasal resistance increases during the night, patients have an adaptive response to switch over to mouth breathing. Once mouth breathing occurs, there is an actual increase in upper airway collapse. With the OADS O₂Vent® device in place the patient will instead of opening their mouth, automatically begin to breathe through the “mouthpiece/duckbill” which will result in a stable airway and normal ventilation.
Mouth breathing offers up to 2.5 times more resistance than nose breathing1. This increase in resistance will result in higher negative pressure swings in the airway, possibly causing airway collapse. Breathing through the O₂Vent® device offers little to no resistance which will reduce negative pressure swings and provide a more stable airway. The design and cross-section of the bi-lateral airway management technology was made to mimic an average patent airway.
Yes. A common physical exam is often used whereby the patient holds one nostril closed while trying to breathe through the other and the clinician can assess nasal breathing restriction. However, as previously mentioned congestion may be intermittent depending on allergies, environment or weather related factors. Another tool that is easily performed and complements the physical examination is the use of a validated questionnaire called the NOSE questionnaire. Consisting of five questions that the patient will answer based on their level of nasal congestion, the questionnaire also includes a scoring severity scale. Using this questionnaire can assist in properly diagnosing nasal congestion which is critical for oral appliance compliance.
The material used is titanium, it is a biocompatible material that is strong yet very light weight. It allows Oventus Medical to provide patients with a customized 3D printed durable airway within the device that is very comfortable and easy to use.
The customized airway gives the illusion that it is larger but when properly fitted the O₂Vent® device can be used by almost everyone. Oventus Medical devices are approximately the same size as other dorsal and Tap style appliances. The fact that it is printed in titanium allows a reduction in wall thickness to around 0.5mm. This means that the appliance can have an airway with the same cross-sectional area as a human nose incorporated into it while maintaining the normal dimensions of a dorsal style appliance.

OADS O₂Vent® devices are the only devices that offer a tangible solution for patients who suffer from multiple levels of obstruction; including soft palate collapse, nasal obstruction, tongue-based obstruction and epiglottal obstruction.
By breathing through the incorporated airway, it has been shown to reduce negative pressure swings in the airway which can lead to airway instability and collapse. Therapy adherence has been shown to be 82.8%. It has also been demonstrated that by using OADS O₂Vent® devices, effectiveness has improved by up to 50%
Yes. All OADS O₂Vent® devices allow for adequate tongue space and with cases where an extremely large tongue is involved the lingual acrylic on the upper arch and the distolingual acrylic on the lower arch can be reduced to create additional space.
Yes. Digital scans as well as impressions can be used to fit the appliance to the patient. More information about digital scans can be found in the Dentist Resource link: https://openairway.ca/pages/dental-medical-professional
The only consideration is that there is a 5mm vertical bite clearance when taking the scans or impressions.

There are 9 different connector band lengths that alter the jaw position, ranging from 13mm to 21 mm.
Connector bands are attached to lugs on either side of the device for lower jaw positioning. Using proprietary OADS software, the placement of the lugs is calculated and customized for each patient, in such a way that they always correspond with the ideal starting titration (utilizing the 19mm length bands). This placement is typically 50%-70% protrusion. Starting at this point allows the clinician to titrate the mandible up to 6mm forward to the 13mm connector band and/or to titrate the mandible up to 2mm backwards to the 21mm connector band.
The OADS Bite Fork is a single use disposable device that is intended to be used in a clinical setting to record a 5mm vertical bite registration. There are two variants available to record bite registrations:
Double Sided– to be used to record an edge to edge bite registration
Single Sided– to record bite registration using a suitable bite measurement tool that will allow incremental and reversible advancement of the patient’s mandible anteriorly, with respect to the maxilla.
Most patients will benefit from the O2Vent Optima. It is a durable oral appliance that has the ability to treat a variety of patients from mild to moderate sleep apnea patients. It can also offer an alternative treatment option to those unable to tolerate traditional oral appliance therapy or who cannot tolerate CPAP therapy.
