Innovation moving medical technology forward

Oventus was developed by the company founder and Clinical Director, Dr Chris Hart. As a sleep disorder sufferer himself, Dr Hart was anxious to find a sleep-disordered  breathing therapy that was better than the current market alternatives. Using his expertise as a professional dentist, he thought he could devise an oral appliance himself that would better increase airflow to the lungs and bypasses multiple sites of obstruction including the nose, tongue and soft palate. In an industry first, Dr Hart partnered with Australia’s peak scientific body, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in 2013 to design a bespoke mouthguard, using innovative titanium 3D-printing technology.

The result was the O2VentTM

With a unique separate airway incorporated into a patented design, the O2VentTM devices allow air to continue to flow unobstructed in the presence of nasal obstruction and/or soft palate collapse while simultaneously preventing tongue collapse and maintaining an oral seal. The O2VentTM addresses multiple levels of obstruction, not just advancing the lower jaw forward to prevent tongue obstruction.

The customised  O2VentTM devices may be particularly beneficial for the many people with nasal obstructions, those that experience soft palate collapse or who are habitual mouth breathers. The product range has developed to now include three titanium devices and the new nylon O2VentTM Optima.   

No matter what style of device you prefer to use for your patients, the Oventus Airway Technology can be incorporated into it. Oventus will continue to launch a range of devices utilising different titration mechanisms – all incorporating the unique airway design and all with the ability for out-of-the-box CPAP connectivity, which is well advanced in product development.

The Oventus Medical Quality System is fully accredited according to ISO 13485 international standards.

Do you screen your patients for OSA?

A recent population study cited 17% of females and 22% of male subjects suffered from Obstructive Sleep Apnoea*. As a dentist, you are well positioned to recognise the signs and symptoms of Obstructive Sleep Apnoea in your patients. Screening your patients, and discussing signs and symptoms, will assist them in making the first step in their treatment journey. As a dentist, you have an important role to play in supporting your patients through diagnosis and treatment of their sleep disordered breathing. With appropriate training and experience in dental sleep medicine, many dentists are recognising the potential to increase the service offering of their practices, and to provide life-changing professional services in Dental Sleep Medicine to their patients. Of the millions of patients that suffer OSA, nasal obstruction and soft palate collapse are major contributing factors, which may not be adequately dealt with by mandibular advancement alone. With variable success rates for surgery in these patients, the O2VentTM technology may be of benefit.

To help you start screening your patients for OSA, and for assistance in discussing Oventus Airway technology as part of a treatment platform, you may find the following link useful: Find a Sleep service near you * Defined at an apnea-hypopnea index (AHI) ≥5 for eleven published epidemiological studies published between 1993 and 2013.

How the O2VentTM works


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 lips are closed around it to maintain an oral seal


Air passes through to the back of the device in an enclosed airway


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

For a more detailed explanation of how the unique design allows for breathing through the device, bypassing obstruction in the nose which can contribute to snoring and sleep apnoea, simply watch this video.

The Oventus Treatment Platform

The Unique O2VentTM Oral Devices offer three key benefits



The O2VentTM custom mouthguard devices are custom made for you to provide a perfect fit. Made from a titanium core inserted into soft mouthguards, these lightweight sleep apnoea treatment devices weigh only 35 grams (1.23 oz). The streamlined design has enabled an airway to be built into the device whilst not obstructing the tongue.



The lightweight device has no mask or complicated machines attached, so it is easy to take with you as you travel, and store during the day when not in use.


Oventus Airway Technology — The Second Nose

Each O2VentTM device has an airway incorporated into it about the size of a healthy human nostril. Air enters the mouth and is delivered to the back of the throat, so you can breathe through the device while maintaining an oral seal, to avoid a dry mouth or sore throat.

Clinical trial results with O2VentTM Mono

100% of patients experienced significant improvement in snoring using the O2VentTM
82% of patients experienced complete elimination of snoring using O2VentTM
76% of patients decreased their Apnea-Hypopnea Index (AHI) by more than 50%**

Ongoing Clinical Studies are taking it further

Current studies are looking at upper airway physiology and the effect of Oventus’ low-resistance airway on pharyngeal collapsibility when used in combination therapy — not just the reduction in pressure requirements but also the ability to breathe physiologically while simultaneously applying CPAP. If the clinical data continues to support these early findings, these two advances may represent a significant paradigm shift in the treatment of OSA.

The webinar, ‘An Introduction to Oventus Airway Technology’ is available to view and listen to.

Commonwealth research grant awarded

Oventus Medical has recently been announced as the lead participant in a AUD$3 million Australian Government grant to advance research into the treatment of Obstructive Sleep Apnoea. Alongside industry and scientific experts in the field, Oventus Medical will work with NeuRA (Neuroscience Research Australia) and the CSIRO (Commonwealth Science and Industrial Research Organisation) on some exciting research exploring the benefit of the Oventus airway design as part of a treatment approach in progressive OSA treatments, such as algorithms for treatment success, in-built compliance and efficacy monitoring and miniaturised CPAP pumps.

Education in Dental Sleep Medicine

Dentists practising in the field of Dental Sleep Medicine should follow the recommendations for practice protocol as reported in the most recent American Academy of Sleep Medicine publication ‘Practice Parameters for the Treatment of Snoring and Obstructive Sleep Apnea with Oral Appliances.’ Oventus encourages dentists to undertake regular appropriate training and educational activities to ensure their knowledge is up to date in this area. Further details of accredited and approved courses are available from the Australasian Sleep Association. Dentists interested in practising in this field are encouraged to become associate members of the ASA and to attend and participate in the annual scientific meetings. These conferences will offer postgraduate introductory courses in Oral Sleep Medicine and present current scientific content in all sleep disorders.

Oventus also recommends internationally recognised training through Tufts University School of Dental Medicine. See the attached flyer for a Tufts University Dental Sleep Medicine Comprehensive Introduction Program in Singapore in April and July 2019.
