Read the first 6 CMT Sleep Disorders & Bruxism flashcards as text

  1. What is the AASM (American Academy of Sleep Medicine) threshold for mild obstructive sleep apnea in adults based on AHI?

    Answer: AHI ≥ 5 events/hour

    The AASM defines mild OSA as an AHI of 5–14 events per hour, moderate as 15–29, and severe as ≥30, providing the classification framework used in collaborative care.

  2. How does correct tongue posture (resting on the palate) mechanically support the airway during sleep?

    Answer: It reduces soft tissue prolapse by providing structural support to the oropharyngeal walls

    The tongue resting against the palate provides a structural brace that supports the lateral oropharyngeal walls, reducing the tendency for soft tissue to collapse into the airway during sleep.

  3. A myofunctional therapist collaborating on a bruxism case should primarily coordinate with which type of provider?

    Answer: Dentist or prosthodontist managing occlusal splint therapy

    Bruxism management typically involves a collaborative approach between the myofunctional therapist (addressing muscle habits and airway) and the dentist or prosthodontist (providing occlusal splint protection).

  4. Which of the following exercises is specifically used to strengthen the soft palate and reduce palatal vibration during sleep?

    Answer: Sustained vowel phonation ('aah' with uvular elevation)

    Sustained vowel phonation exercises that elevate the soft palate and uvula strengthen the levator and tensor veli palatini muscles, reducing soft palate laxity and vibration-related snoring.

  5. What is the significance of mouth taping during sleep in myofunctional therapy?

    Answer: It is a temporary adjunct to reinforce nasal breathing habits during sleep in patients without obstructive issues

    Mouth taping is used as a behavioral adjunct to encourage nasal breathing during sleep and should only be used in patients confirmed to have adequate nasal patency, not as a standalone treatment.

  6. Which biomarker related to sleep quality improvement is sometimes tracked in myofunctional therapy research to validate treatment outcomes?

    Answer: Oxygen desaturation index (ODI) from home sleep testing

    The oxygen desaturation index, measured via home sleep testing, provides an objective biomarker that reflects nighttime breathing quality and can demonstrate improvements following myofunctional therapy.
