    We’re here to answer your questions

The following are some of the questions patients and clinicians frequently ask. If you have a question that is not here, please email us.

 

  • What is the difference between the Oventus O2Vent and other oral devices?

    Like all oral appliances that bring the jaw forward, the O2VentTM stabilises the jaw position and brings the tongue forward to reduce airway collapse. In addition, the unique airway allows for breathing through the device to bypass obstruction in the nose and soft palate which can contribute to snoring and sleep-disordered breathing.

    Benefits:

    1. Airway
    The O2VentTM has an enclosed airway about the size of a healthy human nose incorporated into it. Air enters the airway between the lips and is delivered through the enclosed airway to the back of the mouth so patients can breathe through the device if they have a blocked nose, soft palate collapse or are mouth breathers, while maintaining an oral seal.

    2. Small and streamlined
    The O2VentTM is 3D printed in medical grade titanium which facilitates its lightweight, thin wall and complex hollow structure incorporating its unique airway. This allows us to build an airway into a more streamlined device that is less than 5mm thick as it passes between the teeth – it’s about the size of a standard mouthguard.

    3. Lightweight
    The uniquely-designed mouthguard weighs approximately 35 grams dependent on the customised design.

    4. Comfort
    The O2VentTM is lined with a medical grade, polymer liner to maximise patient comfort. The design of this customised device comfortably fits around your teeth, and provides ample space to accommodate the tongue.

    If you are interested in the O2VentTM, call us to discuss your situation.

  • What proof do you have that the Oventus device works?

    Oral or mandibular advancement devices – like the O2VentTM are emerging as an accepted alternative treatment for sleep-disordered breathing conditions, with recent studies showing similar long-term health outcomes1. An Oventus clinical trial showed that 100 percent of patients experienced a significant reduction in snoring and an improvement in AHI with 82 percent of patients eliminating snoring completely and 76 percent of patients reducing their AHI by more than half2. Oventus are pleased to announce the first peer-reviewed clinical data was published in the Journal of Dental Sleep Medicine, Vol 4 No.3 July 2017.

    The early design of the O2VentTM has been used for some time in private clinical practice. Developed in 2013, Oventus conducted a pilot study on the design with promising results. After further refinement and in particular using 3D printing technology, the device has been improved to be more comfortable with a more compact device.

  • What is involved in getting an O2Vent?

    Visit the Find a Dentist page on our website to locate an Oventus clinician (dentist) in your area. To obtain an O2VentTM, the process is relatively simple but takes between four weeks to manufacture and deliver your custom-made mouthguard. If your clinician recommends an O2VentTM

    impressions of your teeth and a bite registration will be taken and your device can be manufactured from these records.

    Find out more on the treatment pages.

    If you are interested in the O2Vent, call us to discuss your individual situation.

  • What is the cost?

    The O2VentTM is a custom made medical device, designed specifically for each patient. It is now generally accepted that custom fabricated oral appliances are better tolerated, remain in place during sleep and are more efficacious compared to cheaper off-the-shelf oral appliances.

    The O2VentTM device is fitted and delivered under the supervision of a dentist, and is available from an Oventus Accredited Clinician. Total treatment costs should be discussed with your Oventus Clinician.

  • What rebates can I claim back on Medicare or private insurance?

    Rebates for the O2VentTM are available through private health insurers, not Medicare. If you are required to have X-rays as part of your treatment plan, these may be rebatable through Medicare or your private health insurance. You must contact your health insurer to find out the rebate which may vary between funds and policy.

  • What are the risks?

    There are some possible risks with using an oral device for sleep therapy and that includes the O2VentTM.  It is best to speak with your Oventus Accredited Clinician about the risks that are relevantto you. The O2VentTM is completely removable so if you have any concerns, you can simply remove it and contact your Oventus Trained Clinician.

  • How do I know if I am a candidate?

    Whether you snore, or have more severe sleep-disordered breathing, you are likely to benefit from the O2VentTM. The O2VentTM is particularly helpful for people with nasal obstruction. You can register online for free at www.oventus.com.au and Oventus will contact you to discuss your sleep history to find out if you are a candidate. This will be confirmed by your Oventus Trained Clinician. Or you can locate an Oventus Accredited Clinician/Dentist on our website and contact them to discuss.

  • Do I need to do a sleep study?

    Sleep physicians often recommend a sleep study before an oral appliance is prescribed (to determine the diagnosis), and after the oral appliance is used to determine if it is. A diagnostic sleep study resulting in a diagnosis of a sleep-disordered breathing condition is necessary to be eligible for any private health insurance rebates. Please talk to your Oventus Trained Clinician or GP to arrange this.

  • What outcome can I expect?

    With any oral appliance on the market, studies show that more than 75 percent of people with severe sleep-disordered breathing improve their sleep significantly1. About 54 percent improve to measure an AHI level of less than 10. Of those who do not improve to less than 10, 21 per cent of these will improve their AHI level by at least half1.

    More than 1,000 people are now using the O2VentTM Mono. The Oventus clinical trial reported an average usage of the device six nights per week and an average of seven hours per night, resulting in a compliance of 82.8%2. This study also showed that 100 percent of patients experienced a significant reduction in snoring and an improvement in AHI with 82 percent of patients eliminating snoring completely and 76 percent of patients reducing their AHI by more than half2.

  • How do I know it will work for me?

    Many people already using the O2VentTM are reporting exceptional results. Before recommending an O2VentTM to anyone, an Oventus Trained Clinician will thoroughly assess every patient’s situation to ensure suitability.

  • Is it suitable if I have dentures?

    Yes, depending on the patient. Wearers of partial dentures may be able to order an  O2VentTM device. They would need to have an individual assessment by their Oventus clinician to determine suitability. Unfortunately, patients with full upper and lower dentures are not suited to use the O2VentTM device.

    Please contact us if you are interested and we can discuss your situation with you.

  • Is it suitable for a mouth breather or patients with nasal congestion?

    Yes. The O2VentTM does not prevent you from breathing through the nose, but provides an additional airway within the device to create a low resistance airway to breathe through the device as well. Although counterintuitive, the O2VentTM actually prevents oral breathing. Oventus clinical trial data shows that compliance with treatment did not appear to be reduced by the presence of nasal congestion2.

  • Does it maintain an oral seal like other oral devices?

    Yes. The O2VentTM allows the patient to maintain an oral seal. However, unlike other oral appliances, it provides an auxiliary airway to breathe through. The auxiliary airway is the same size as a healthy human nose, as such providing an additional airway to breathe through while keeping your mouth closed. This is beneficial to patients who experience nasal obstruction, soft palate  collapse and those who may feel claustrophobic.

  • How does the O2Vent device prevent dry mouth syndrome?

    The airway in the O2VentTM is fully enclosed from the intake at the front of the mouth to the pharynx at the back of the mouth so the air doesn’t come into contact with the mouth as the patient breathes through the device airway. While maintaining an oral seal, it provides a “second nose” for the patient to breathe through if they cannot get enough air due to nasal congestion or obstruction.  It converts mouth breathers to “pseudo” nose breathers.

  • Does the Oventus device emit any noise when you exhale?

    The O2VentTM makes a slight noise when the patient breathes through it – very much like deep breathing. Patients and their partners find it far quieter than snoring or alternative breathing devices.

  • Does it make a person gag?

    The O2VentTM sits between the teeth and the cheeks. It does not extend over the palate or the tongue so we have not had any issues with patients gagging from it and we have treated some very severe gaggers.

  • What is the regulatory status of O2Vent?

    The O2VentTM devices are included in the ARTG (Australian Register of Therapeutic Goods), O2VentTM Mono – ARTG 230890, O2VentTM T – ARTG 275667 and O2VentTM W – ARTG 286864.

  • Where do I go to get the O2Vent?

    The O2VentTM is available through Oventus Trained Clinicians – dentists who have undergone the training required to assess your suitability to O2VentTM treatment, and take bite registration and impressions of the top and bottom teeth. We are accrediting Clinicians frequently and adding to our existing network. Look for the “Find a Dentist” page on the Oventus website at www.oventus.com.au/find-dentist/.

  • What if I live in a regional or remote area?

    Oventus is increasing its network of Oventus Accredited Clinicians across Australia. But if you live in an area not serviced by an Oventus Accredited Clinician you can provide contact details of your preferred dentist to us and we will be happy to invite them to participate in accreditation training.

  • How do I clean my Oventus device?

    By following the instructions for use that is provided with the Oventus kit, the O2VentTM should remain in good condition. After each time you use your device, rinse it in lukewarm water. Clean your device using a toothbrush (not the same one you use to clean your teeth with as toothpaste can damage your device). Shake as much water off your device as possible and dry with a clean tissue or towel and store in your storage box.

    Twice a week, clean your device more thoroughly using effervescent antibacterial cleaning tablets recommended by your Oventus Accredited Clinician. Half fill a conatainer with water and place the tablet and your device in the container ensuring it is completely submerged. Leave to clean for 15 minutes. Rinse both the device and the tub well in warm water and dry as you do daily.

    If you have any questions about care and maintenance of your device, please call us or email reception@oventus.com.au.
