In short

Sleep apnea is a disorder where breathing is interrupted repeatedly during the night due to airway narrowing or blockage. These pauses, called apneas, can last from seconds to over a minute and repeat multiple times nightly, restricting oxygen flow to the lungs. Over 80% of cases remain undiagnosed. At our clinic, we use custom mandibular advancement devices (MAD) that gently reposition the jaw during sleep, keeping airways open for adequate airflow and restorative rest. This non-invasive and comfortable alternative to CPAP has a 98% tolerance rate and shows improvement in the apnea-hypopnea index in 93.5% of patients.

Why Treating Sleep Apnea is Essential

Untreated sleep apnea is more than just snoring—sleep apnea has serious implications for your overall health and quality of life.

  • Cardiovascular Risk

    Sleep apnea significantly increases the risk of hypertension, heart disease, stroke, and irregular heartbeat.

  • Cognitive Decline

    Chronic oxygen deprivation during sleep can lead to memory problems, difficulty concentrating, and increased dementia risk.

  • Chronic Fatigue

    Poor sleep quality leads to persistent daytime sleepiness, affecting work performance, driving safety, and relationships.

  • Metabolic Impact

    Untreated sleep apnea is linked to diabetes, weight gain, and metabolic syndrome, creating a vicious cycle.

  • Mental Health

    Sleep apnea is strongly associated with depression, anxiety, and mood disorders due to chronic sleep disruption and oxygen deprivation.

  • Accident Risk

    Excessive daytime sleepiness increases the risk of motor vehicle accidents and workplace injuries by up to 2-3 times.

Mandibular Device vs CPAP for Sleep Apnea

2024-2025 scientific studies on sleep apnea show equivalent health outcomes between both sleep apnea treatments.

FeatureMandibular DeviceCPAP
Tolerance Rate98% of patients~50-60% long-term
ComfortDiscreet and silentMask with noise
PortabilityFits in hand, no electricityBulky equipment, requires power
TravelIdeal — compact and practicalChallenging — extra baggage
AHI ReductionEffective (mild-moderate)Superior (all levels)
Blood PressureEquivalent reduction (CRESCENT trial)Equivalent reduction
Severe ApneaCan be combined with CPAPFirst-line treatment

What Studies Say

The CRESCENT trial (2024) on sleep apnea with 321 participants demonstrated that the mandibular device is non-inferior to CPAP in sleep apnea treatment. Greater adherence to sleep apnea devices offsets the efficacy difference.

Candidates for Sleep Apnea Treatment

Is Sleep Apnea Treatment Right For You?

Excellent Candidates for Sleep Apnea Treatment

  • Mild to moderate obstructive sleep apnea
  • Primary snoring
  • Sleep apnea patients who don't tolerate CPAP
  • Frequent travelers with sleep apnea
  • Those who value discretion and comfort in sleep apnea treatment
  • Sleep apnea patients with associated bruxism
  • Those preferring non-invasive sleep apnea treatment

Sleep Apnea Cases to Evaluate

  • Severe sleep apnea (may require CPAP or combination)
  • Central sleep apnea
  • Severe temporomandibular joint problems
  • Few natural teeth or unstable dentures
  • Morbid obesity (BMI > 40)

* These sleep apnea cases require individual evaluation. In many situations, the sleep apnea device can be used in combination with other therapies.

04 Common questions

Frequently asked questions

What is sleep apnea?
Sleep apnea is a disorder where breathing is interrupted repeatedly during the night due to airway narrowing or blockage. These pauses can last from seconds to over a minute and repeat multiple times nightly, restricting oxygen flow. Over 80% of cases remain undiagnosed.
What are the symptoms of sleep apnea?
Common symptoms include daytime drowsiness, concentration problems, morning headaches, loud snoring, dry mouth upon waking, constant fatigue, and mood disturbances. Many patients experience these symptoms gradually without recognizing the underlying cause.
How does the mandibular advancement device work?
The mandibular advancement device gently repositions the jaw forward during sleep, keeping airways open for adequate airflow. It is comfortable, easily adjustable, and non-invasive, providing restorative rest.
What is the difference between the mandibular device and CPAP?
CPAP uses a mask with pressurized air, while the mandibular device is a discreet, silent oral appliance. The mandibular device has a 98% tolerance rate, is easier to travel with, and requires no electricity, making it a more comfortable alternative for many patients.
What is the treatment success rate?
93.5% of patients show improvement in the apnea-hypopnea index with the mandibular advancement device. Additionally, 98% of patients tolerate the device without issues, making it a highly effective treatment option.
What are the risks of untreated sleep apnea?
If untreated, sleep apnea can lead to serious complications including hypertension, cardiac problems, metabolic syndrome, diabetes, erectile dysfunction, depression, and cognitive impairment. Proper treatment can prevent these complications.
What is the treatment process?
The process follows 4 steps: 1) Detection - symptom evaluation, 2) Diagnosis - sleep studies (polysomnography) by specialists, 3) Treatment - custom mandibular advancement device prescribed by dentist, 4) Follow-up - collaborative monitoring by dentist and sleep specialists.
How long does it take to adapt to the device?
Most patients adapt to the device within 1-2 weeks. During this period, you may feel slight pressure or discomfort that quickly diminishes. The device is adjustable to ensure maximum comfort.
Is a medical referral necessary?
It is not strictly necessary, but we work in collaboration with sleep doctors and pulmonologists. If you already have a diagnosis or sleep study, bring it to the consultation. Otherwise, we can guide the entire diagnostic process.
Does health insurance cover the treatment?
Coverage varies by insurance plan. Many insurances cover part of sleep apnea treatment. Our team will help verify your coverage and prepare all necessary documentation for reimbursement.
What do scientific studies say about the effectiveness of mandibular devices?
Recent 2024-2025 studies confirm that while CPAP is superior in reducing the apnea-hypopnea index (AHI), clinical outcomes are similar. The CRESCENT trial demonstrated that mandibular devices are non-inferior to CPAP in reducing blood pressure. The superior adherence to mandibular devices (patients use them more consistently) offsets the efficacy difference, resulting in equivalent health benefits.
Is there a relationship between sleep apnea and bruxism?
Yes, polysomnographic studies reveal that about 50% of adults with obstructive sleep apnea also have sleep bruxism. Both conditions share risk factors such as stress, alcohol consumption, and obesity. Interestingly, the mandibular advancement device can help treat both conditions simultaneously, protecting teeth while keeping airways open.
How is the device made? Is it customized?
Yes, each device is fully customized. We use advanced digital technology: we perform a 3D intraoral scan of your mouth (no traditional impressions), the design is computer-aided, and the device is manufactured with 3D printing or CNC milling. This process ensures a precise and comfortable fit, adapted to your unique jaw biomechanics.
Does the mandibular device work for all types of sleep apnea?
The mandibular advancement device is particularly effective for mild to moderate obstructive sleep apnea and snoring. In severe apnea cases, it can be used in combination with CPAP or as an alternative when the patient does not tolerate CPAP. Individual assessment will determine if it is the best option for your case.
Does the device have long-term side effects?
Studies with 10+ years of follow-up show that minor dental changes may occur long-term, but these are generally subclinical and do not preclude continued use. We regularly monitor your occlusion and dental health during treatment. Most patients consider these changes minimal compared to the benefits of apnea treatment.
Can I use the device if I travel frequently?
This is one of the great advantages of the mandibular device! It is small, lightweight, silent, and requires no electricity — ideal for travel. It fits easily in a bag or carry-on. Many patients who use CPAP at home opt for the mandibular device when traveling for convenience.
How long does the device last?
With proper care, a quality mandibular advancement device typically lasts 3-5 years. Durability depends on factors such as bruxism (teeth grinding), device hygiene, and handling. We provide detailed care instructions and perform regular checks during follow-up appointments.
