Sleep Apnea Appliance Therapy

What is obstructive sleep apnea?

Obstructive sleep apnea (OSA) is a condition in which the airway repeatedly narrows or collapses during sleep. These breathing pauses can last several seconds and may occur dozens of times per hour.

Each time your airway closes, oxygen levels can drop and your brain briefly wakes you up so you can start breathing again. You may not remember waking, but your body does—leaving you exhausted and increasing stress on the heart, blood vessels, and other organs.

Common signs & symptoms

• Loud, habitual snoring
• Gasping or choking sounds during sleep
• Morning headaches or dry mouth
• Daytime fatigue or “brain fog”
• Irritability, mood changes, or difficulty concentrating
• Partner noticing pauses in breathing at night

Untreated sleep apnea is linked with high blood pressure, heart disease, stroke, and metabolic conditions. Getting effective treatment is about much more than snoring—it is about protecting your overall health.

CPAP vs. oral appliance therapy

Continuous positive airway pressure (CPAP) is a very effective treatment for moderate to severe sleep apnea when used consistently. However, many patients struggle with:

• Mask discomfort or skin irritation
• Claustrophobia or difficulty sleeping with the mask
• Dry nose or throat
• Noise from the machine
• Challenges of traveling with the equipment

Oral appliance therapy utilizes a small, custom oral device—similar to a retainer or night guard—instead of a mask and machine. For patients with mild to moderate OSA, and for some patients who cannot tolerate CPAP, it can be an excellent alternative or combination therapy.

How an oral appliance helps you breathe better

Most sleep apnea oral appliances are a type of mandibular advancement device (MAD). The appliance gently positions the lower jaw slightly forward, helping to stabilize the tongue and soft tissues so they are less likely to fall back and block the airway.

As specialists in bite and jaw relationships, our prosthodontists are uniquely qualified to design appliances that:

• Open the airway while respecting your jaw joints (TMJs)
• Work with crowns, implants, and other restorations
• Balance comfort, effectiveness, and long-term tooth health

Benefits of a custom sleep appliance

• No mask, tubing, or machine
• Easy to travel with—fits in a small case
• Quiet therapy for you and your partner
• Often easier to adapt to than CPAP
• Can be adjusted over time to optimize results

What to expect at your visit

Sleep & health review

1. We begin with a thorough discussion of your sleep history, medical conditions, and current or past treatments, including CPAP if applicable.

2. Screening exam & records: Your prosthodontist evaluates your teeth, bite, jaw joints, and airway. We may take digital scans, photographs, and other records to help plan your appliance.

3. Collaboration with your physician: A medical diagnosis of sleep apnea is typically made by a physician through a sleep study. We coordinate with your sleep specialist or primary care provider to ensure your treatment plan is appropriate and medically supervised.

4. Custom appliance design: Using your digital scans and exam findings, we design a device tailored to your bite, jaw mobility, and airway needs. The appliance is fabricated in a high-quality dental laboratory.

5. Fitting, adjustments & follow-up: Once your appliance is ready, we fit and fine-tune it for comfort. We gradually adjust it to achieve effective airway support, and we work with your physician on any follow-up testing to confirm that your sleep apnea is well controlled.
