UARS Sydney Clinic

Restore your good night's sleep

Upper Airway Resistance Syndrome can also be thought of as “The Young Fit, Female Syndrome”.

As in sleep apnoea, the soft tissue of the airway in UARS patients relaxes while one sleeps. This reduces the size of the airway. The resulting increased effort to inhale results in an arousal in an effort to increase oxygenation. These recurrent microarousals are called Respiratory Effort-related Arousals (RERAs).

More often than not, the traditional indices or parameters used to measured sleep quality, such as Apnoea/Hypopnoea Index (AHI) and Oxygen Desaturation Index (ODI) are not as bad in UARS patients compared to sleep apnoea patients. This is because the patients are often so hypervigilant in their sleep that they never end up having a partial or complete obstruction.

What are some dental findings?

  • Narrow, high-arched palates
  • Small inter-molar distances
  • Dental overjet >3mm
  • Long face with short narrow chin
  • Thin soft palate mucosa with a short uvula
  • TMJ click often seen
  • Early extraction of teeth
  • What are some medical signs and symptoms

  • Excessive daytime sleepiness
  • Non-refreshing sleep
  • High anxiety score
  • Cold extremities
  • Postural hypotension
  • Low blood pressure
  • Headaches
  • Irritable bowl syndrome
  • The implications of UARS on your short term and long term general health are profound:

    Brain can't repair from daily activities resulting in:

    • Reduced or impaired consolidation of memories
    • Impaired removal of B-amyloid plaques. Their build up is known to be a causative factor in Alzheimer's disease
    • Impaired cognitive function and development

    Increased risk of cancer due to:

    • The 70% reduction in the activity of natural killer cells which acts to help fight against cancer while we sleep

    Increased sympathetic drive which results in

    • cardiovascular disease
    • stroke
    • impaired bowel movements - possibly irritable bowel syndrome
    • frequent visits to toilet while sleeping

    Impairing many other body systems such as

    • Reproductive system
    • Metabolic system

    Current UARS treatments do not treat the underlying causes. With new training in the field of craniofacial epigenetics, The Dental Station is now positioned to offer the latest treatment for sleep apnoea that can address the underlying issue of underdeveloped jaws.

    The Vivos suite of oral appliances non-surgically alter the bone volume of the upper and lower jaws. These in turn improves the soft tissues supported by these bones. The end result is an increase in the airway volume of the nose and the nasopharynx and oropharynx.

    We take a wholistic approach to our consultations for patients with sleep difficulties. For example:

    - We take a thorough history of your sleep and your general health, trying to see if we can
    connect symptoms or medical conditions back to poor sleep quality.

    - We are able to organise home-based sleep studies that are reported on by sleep physicians.

    - Anatomically, the airway is bordered at the front by the jaws and at the back by the cervical
    spine. So we have a low-dose Cone Beam Imaging machine to take 3D images of your nasal
    and pharyngeal airways, the upper and lower jaws as well as the cervical spine.

    - We assess your posture, because many patients with obstructed airways posture their heads
    forward to help open the airway.

    - We have a working relationship with ENTs, speech pathologists, chiropractors, osteopaths
    and ofcourse sleep physicians.

    For someone suffering with poor sleep quality, the journey to seek help is convoluted. At the Dental Station, we simplify this and help you access the best treatment plan with a multidisciplinary approach. We tailor treatment to your needs.
