Understanding Oral Appliance Therapy for Sleep Apnea Treatment
Oral appliance therapy (OAT) has revolutionized the treatment of obstructive sleep apnea (OSA) and chronic snoring. As a leading dental sleep medicine practice serving Aloha, Hillsboro, Beaverton, and the greater Portland metro area, we specialize in custom-fitted oral appliances that provide a comfortable, effective alternative to CPAP therapy.
If you’ve been diagnosed with sleep apnea—or suspect you may have it—understanding your treatment options is the first step toward better sleep and improved health. This comprehensive guide explains everything you need to know about oral appliance therapy, from how it works to what you can expect during treatment at our Oregon clinic.
What Is Oral Appliance Therapy?
Oral appliance therapy uses a custom-made dental device, worn during sleep, to treat obstructive sleep apnea and snoring. The most common type is called a mandibular advancement device (MAD), which gently repositions your lower jaw (mandible) forward while you sleep.
This forward positioning accomplishes several critical functions:
- Opens the airway: By advancing the lower jaw, the device physically enlarges the space behind the tongue and soft palate
- Prevents tissue collapse: The repositioned jaw keeps the tongue from falling backward and blocking airflow
- Reduces soft tissue vibration: Less obstruction means less vibration of tissues—eliminating or reducing snoring
- Maintains oxygen levels: With an open airway, oxygen saturation remains stable throughout the night
Unlike CPAP therapy, which uses continuous positive airway pressure to keep the airway open, oral appliances work mechanically without the need for masks, hoses, or electricity.
FDA Approval and Clinical Evidence
Oral appliances for sleep apnea are FDA-cleared medical devices, not over-the-counter mouthpieces you might find online. The American Academy of Sleep Medicine (AASM) and American Academy of Dental Sleep Medicine (AADSM) recognize oral appliance therapy as:
- First-line treatment for mild to moderate obstructive sleep apnea
- Alternative therapy for patients with severe OSA who cannot tolerate CPAP
- Preferred treatment for primary snoring
Clinical research consistently demonstrates that custom oral appliances significantly reduce the apnea-hypopnea index (AHI), improve oxygen saturation, decrease snoring, and enhance quality of life for patients in Washington County and beyond.
How Oral Appliances Work: The Science Behind the Treatment
To understand how oral appliances work, it helps to know what causes obstructive sleep apnea. During sleep, the muscles supporting your airway relax. In people with OSA, this relaxation allows the tongue and soft tissues to collapse backward, partially or completely blocking airflow.
When airflow is blocked:
- Oxygen levels drop throughout your body
- Carbon dioxide builds up in your bloodstream
- Your brain triggers a brief arousal to restore breathing
- This cycle repeats—sometimes hundreds of times per night
These constant interruptions prevent you from reaching the deep, restorative stages of sleep you need for optimal health and daytime functioning.
A mandibular advancement device interrupts this destructive cycle by mechanically holding the lower jaw in a forward position. This advancement:
- Increases the cross-sectional area of the upper airway
- Tenses the pharyngeal muscles, making them less likely to collapse
- Positions the tongue forward, away from the back of the throat
- Stabilizes the hyoid bone, supporting airway patency
The result? Continuous, unobstructed breathing throughout the night—without the need for pressurized air from a CPAP machine.
Benefits of Oral Appliance Therapy
Comfort and Convenience
The primary advantage of oral appliances over CPAP is comfort. Many patients find CPAP masks claustrophobic, noisy, or disruptive to their sleep. Oral appliances, by contrast, are:
- Silent: No motor noise or air sounds to disturb you or your partner
- Compact: Fits in a pocket or small carrying case
- Simple: No electricity, hoses, water chambers, or complex setup
- Travel-friendly: TSA-approved and easy to use in hotels, airplanes, or camping
- Natural: Allows normal mouth breathing, talking, and drinking water
Higher Compliance Rates
Treatment only works if you use it. Studies show that oral appliance users have significantly higher compliance rates than CPAP users. Because the device is comfortable and easy to use, patients wear it consistently—often every night without exception.
This improved compliance often translates to better real-world outcomes, even if CPAP shows slightly higher efficacy in controlled laboratory settings. A treatment you wear every night is more effective than one you leave in the closet.
Improved Quality of Life
Patients using oral appliances at our Aloha practice report:
- Deeper, more restorative sleep
- Reduced daytime fatigue and sleepiness
- Improved concentration and cognitive function
- Better mood and reduced irritability
- Decreased morning headaches
- Improved bed partner sleep (no more snoring complaints)
- Greater intimacy without CPAP equipment interference
Health Benefits
Effective treatment of sleep apnea—whether with oral appliances or CPAP—reduces the serious health risks associated with untreated OSA:
- Cardiovascular disease: Lower risk of hypertension, heart attack, and stroke
- Metabolic health: Improved blood sugar control and reduced diabetes risk
- Mental health: Decreased depression and anxiety symptoms
- Accident prevention: Reduced risk of drowsy driving accidents
- Cognitive function: Protection against memory problems and cognitive decline
Who Is a Candidate for Oral Appliance Therapy?
Oral appliance therapy is appropriate for many—but not all—sleep apnea patients. The best candidates include:
Ideal Candidates
- Mild to moderate OSA: Apnea-hypopnea index (AHI) between 5 and 30 events per hour
- Primary snoring: Snoring without significant apnea events
- CPAP intolerant: Patients who have tried and failed CPAP therapy
- CPAP non-compliant: Those who cannot consistently use CPAP despite best efforts
- Adequate dentition: Sufficient healthy teeth for appliance retention (typically 8-10 per arch)
- Good jaw function: Adequate range of motion and no severe TMJ disorders
Patients Who May Benefit with Modifications
- Severe OSA: May use oral appliances in combination with other therapies
- Partial denture wearers: Custom designs may accommodate partial plates
- Mild TMJ issues: Specific appliance designs can minimize jaw stress
Who Is NOT a Candidate
- Central sleep apnea: Oral appliances only treat obstructive apnea
- Full denture wearers: Insufficient teeth for device retention
- Severe periodontal disease: Loose teeth cannot support the appliance
- Limited jaw mobility: Inability to protrude the mandible forward
- Severe obesity hypoventilation: May require more aggressive treatment
During your consultation at our Hillsboro-area office, we’ll evaluate your specific situation and recommend the most appropriate treatment path.
The Oral Appliance Therapy Process at Our Practice
Step 1: Comprehensive Consultation
Your journey begins with a thorough evaluation at our Aloha office. During this visit, we:
- Review your medical history and sleep study results
- Perform a comprehensive oral examination and assess your dentition
- Evaluate jaw function and range of motion
- Screen for TMJ disorders that might affect treatment
- Discuss your symptoms, concerns, and treatment goals
- Explain the different appliance options available
- Answer all your questions about oral appliance therapy
If you haven’t yet had a sleep study, we can coordinate home sleep apnea testing (HSAT) through a referring physician. Remember, sleep apnea diagnosis must come from a medical doctor.
Step 2: Digital Impressions and Records
Once we determine oral appliance therapy is appropriate for you, we take detailed records:
- Digital or physical impressions: Precise molds of your upper and lower teeth
- Bite registration: Recording your natural jaw relationship
- Protrusive range measurement: Documenting how far forward your jaw can move
- Photographs: Documenting your starting point for comparison
These records are sent to a specialized dental laboratory that fabricates custom oral appliances to exact specifications.
Step 3: Appliance Fabrication
Your custom appliance is manufactured to exact specifications. This process typically takes 2-3 weeks. We use only FDA-cleared devices from reputable manufacturers, including:
- Respire (Blue and Pink series): Highly adjustable, comfortable designs with precision titration
- EMA (Elastic Mandibular Advancement): Lightweight with interchangeable straps for easy adjustment
- Herbst appliance: Durable metal advancement mechanism with precise adjustment capability
- TAP (Thornton Adjustable Positioner): Single-point adjustment mechanism for quick titration
The specific device recommended for you depends on your anatomy, preferences, and clinical needs.
Step 4: Fitting and Initial Calibration
When your appliance arrives, you’ll return for a fitting appointment. During this visit, we:
- Verify proper fit on both dental arches
- Adjust retention for comfort and security
- Set an initial mandibular advancement position (typically 50-60% of maximum protrusion)
- Teach you how to insert, remove, and adjust the device
- Provide morning jaw exercises to maintain normal function
- Give you written care instructions
- Schedule your follow-up appointments
Step 5: Titration and Optimization
Oral appliance therapy requires gradual adjustment (titration) to find the optimal jaw position—the setting that effectively treats your apnea while remaining comfortable. Over 4-8 weeks, you’ll:
- Advance the appliance incrementally as directed (usually 0.25-0.5mm at a time)
- Track your symptoms and sleep quality using our monitoring tools
- Return for follow-up visits to assess progress
- Report any discomfort or side effects
This careful titration process maximizes effectiveness while minimizing side effects. Rushing this step can lead to unnecessary jaw discomfort.
Step 6: Efficacy Verification
Once you reach what appears to be an optimal setting, we verify treatment effectiveness through a follow-up sleep test (typically a home sleep apnea test). This confirms:
- Reduction in apnea-hypopnea index (AHI) to goal levels
- Improvement in oxygen saturation
- Resolution of symptoms
If the initial results aren’t optimal, we can make further adjustments and retest. Our goal is objective proof that your therapy is working.
Step 7: Ongoing Care and Monitoring
Oral appliance therapy is a long-term treatment requiring periodic follow-up. We recommend:
- Annual evaluations: Checking appliance condition and dental health
- Periodic adjustments: Fine-tuning as needed over time
- Bite monitoring: Watching for any changes in tooth position
- Replacement planning: Most appliances last 3-5 years with proper care
Our team remains your partner throughout treatment, ensuring continued success.
