Sleep apnea is a common sleep disorder that affects millions of people worldwide. Characterized by repeated interruptions in breathing during sleep, sleep apnea can lead to poor sleep quality, excessive daytime sleepiness, and increased risk of other health issues, such as cardiovascular disease. While continuous positive airway pressure (CPAP) machines are the standard treatment for moderate to severe obstructive sleep apnea (OSA), many individuals find them difficult to use consistently. For those with mild to moderate OSA, oral appliances can offer a less intrusive alternative.
In this blog post, we’ll explore the different types of oral appliances available for sleep apnea treatment, how they work, and their potential benefits and drawbacks.
What Are Oral Appliances for Sleep Apnea?
Oral appliances are custom-made devices that are worn in the mouth during sleep to help keep the airway open. They are designed to be comfortable and easy to use, making them an appealing alternative for people who struggle with CPAP therapy. The goal of these devices is to prevent the airway from collapsing, thereby reducing snoring and the interruptions in breathing that characterize sleep apnea.
Oral appliances are typically prescribed and fitted by dentists or specialists with training in sleep medicine. The most commonly used oral appliances for sleep apnea include mandibular advancement devices (MADs) and tongue-retaining devices (TRDs).
Types of Oral Appliances for Sleep Apnea
Mandibular Advancement Devices (MADs)
Mandibular advancement devices (MADs) are the most popular type of oral appliance for treating sleep apnea. These devices work by slightly advancing the lower jaw (mandible) forward during sleep, which helps to open the airway by preventing the tongue and soft tissues from collapsing into the throat.
- How They Work: By moving the lower jaw forward, MADs help to keep the airway open, allowing for smoother airflow during sleep. The position of the jaw can be adjusted gradually to achieve the most effective fit.
- Customization: MADs are usually custom-made from impressions of your teeth to ensure a snug and comfortable fit. Adjustments can be made over time by a dental professional to ensure optimal results.
- Comfort Level: Most users find MADs to be comfortable once they adjust to wearing them. However, there may be an initial adjustment period during which the jaw and facial muscles adapt to the device.
- Ideal Candidates: MADs are best suited for individuals with mild to moderate OSA and those who do not respond well to or prefer not to use CPAP therapy.
Tongue-Retaining Devices (TRDs)
Tongue-retaining devices (TRDs) work differently from MADs in that they specifically target the position of the tongue rather than the jaw. These devices are designed to hold the tongue in a forward position, preventing it from falling back into the throat and obstructing the airway.
- How They Work: TRDs use a small suction mechanism to hold the tongue in place, creating space in the back of the throat to keep the airway open. This helps to prevent the tongue from blocking airflow during sleep.
- Customization: Unlike MADs, TRDs are often less custom-fitted and may come in a range of sizes that users can choose from. However, some custom-fit options are available for a better fit.
- Comfort Level: TRDs can be more challenging to adapt to compared to MADs, as they may cause initial discomfort or excessive salivation. However, some individuals find them effective once they get used to wearing the device.
- Ideal Candidates: TRDs are typically recommended for people whose sleep apnea is primarily caused by the tongue obstructing the airway. They can be a good option for those who have difficulty using other oral appliances or CPAP.
Hybrid Appliances
Hybrid oral appliances combine elements of both MADs and TRDs to address multiple aspects of airway obstruction. These devices may advance the jaw while also including a mechanism to stabilize the tongue, providing a more comprehensive approach to keeping the airway open.
- How They Work: Hybrid appliances use a combination of jaw advancement and tongue stabilization techniques to maximize the airway space. They are generally custom-made for the individual.
- Customization: Like MADs, hybrid devices are typically custom-fitted to ensure a comfortable fit and effective treatment.
- Comfort Level: Comfort can vary, and some individuals may require a longer adjustment period to adapt to wearing these appliances.
- Ideal Candidates: Hybrid devices may be recommended for individuals who have complex airway obstruction patterns that involve both the jaw and tongue, making them a more versatile option for certain patients.
Benefits of Oral Appliances for Sleep Apnea
Oral appliances offer several benefits, particularly for those who are unable to tolerate CPAP therapy:
- Non-Invasive and Portable: Unlike CPAP machines, oral appliances are small and do not require power, making them easy to travel with and discreet to use.
- Greater Comfort and Compliance: Many people find oral appliances to be more comfortable and less cumbersome than CPAP masks, leading to better compliance with treatment.
- Custom Fit for Optimal Comfort: Oral appliances are custom-made for each patient, ensuring a good fit and reducing the likelihood of discomfort or irritation.
- Less Noise: Unlike CPAP machines, oral appliances are silent, which can be a significant benefit for those who are sensitive to noise or have bed partners who are light sleepers.
Potential Drawbacks of Oral Appliances
While oral appliances can be effective, they may not be suitable for everyone:
- Effectiveness for Severe OSA: Oral appliances are generally more effective for mild to moderate OSA and may not provide sufficient relief for individuals with severe OSA. In such cases, CPAP therapy or other interventions may be necessary.
- Jaw and Dental Discomfort: Some users experience discomfort in the jaw, teeth, or gums, especially during the initial adjustment period. Regular follow-ups with a dental professional can help mitigate these issues.
- Potential for Bite Changes: Long-term use of mandibular advancement devices can sometimes cause changes in bite alignment or the position of teeth. Regular monitoring by a dentist can help manage this risk.
- Not Always Covered by Insurance: Depending on your insurance plan, oral appliances may not be fully covered, leading to out-of-pocket expenses for the device and fittings.
What to Expect When Getting an Oral Appliance
If you decide to pursue treatment with an oral appliance for sleep apnea, here’s what you can expect:
- Initial Consultation: Your dentist or sleep specialist will evaluate your condition and determine if an oral appliance is suitable for you.
- Custom Impressions: Impressions or digital scans of your teeth will be taken to create a custom-fit appliance.
- Fitting and Adjustments: Once your appliance is ready, you’ll have a fitting appointment to ensure it fits properly and make any necessary adjustments.
- Follow-Up Visits: Follow-up visits are crucial to ensure the appliance remains effective and comfortable, and to address any issues like jaw discomfort or bite changes.
- Sleep Study: In some cases, a follow-up sleep study may be conducted to assess the effectiveness of the oral appliance in reducing sleep apnea events.
Conclusion
Oral appliances can be a valuable alternative to CPAP therapy for individuals with mild to moderate obstructive sleep apnea. They are non-invasive, portable, and can be customized for optimal comfort. However, like any treatment, they have their limitations and may not be suitable for everyone. It’s important to consult with a sleep specialist or qualified dentist to determine the best approach for your specific needs.
