What Is A Mandibular Repositioning Device?

A Mandibular Repositioning Device, also known as a Mandibular Advancement Device (MAD), is a custom-fitted oral appliance worn during sleep. The primary function of this device is to gently move the lower jaw (mandible) forward, which helps keep the airway open and prevents the soft tissues at the back of the throat from collapsing and causing obstruction.

These devices are typically made of durable plastic and look similar to mouthguards used in sports. However, MRDs are specifically designed with adjustable components that control the precise positioning of your jaw. Most designs feature two pieces that fit over your upper and lower teeth, connected in a way that holds the lower jaw in a slightly advanced position throughout the night.

How Mandibular Repositioning Devices Work

The effectiveness of a Mandibular Repositioning Device lies in its ability to address the root cause of obstructive sleep apnea. When we sleep, the muscles in our throat relax, which can cause the airway to narrow or collapse completely in some individuals. This collapse leads to breathing pauses known as apneas, which disrupt sleep and reduce oxygen levels.

By repositioning the lower jaw forward, an MRD creates more space in the back of the throat. This forward movement tightens the soft tissues and muscles of the upper airway, preventing them from collapsing and blocking airflow. The tongue is also pulled forward, away from the back of the throat, further reducing the chance of airway obstruction.

Most devices allow for gradual adjustment, typically in small increments of 1-2 millimeters. This adjustability enables healthcare providers to find the optimal position that balances comfort with therapeutic effectiveness for each patient.

Provider Comparison: Leading Mandibular Device Manufacturers

When considering a Mandibular Repositioning Device, the quality and reputation of the manufacturer matter significantly. SomnoMed offers the SomnoDent line, which features precision-crafted devices known for their comfort and durability. These devices use a unique dual-laminate construction that provides both rigidity and comfort.

ResMed, primarily known for CPAP machines, produces the Narval CC, a lightweight device made from biocompatible materials. The Narval uses a unique connector system that allows for natural mouth movement while maintaining jaw advancement.

ProSomnus specializes in digitally manufactured devices that are exceptionally thin and comfortable. Their devices feature a precision fit and are made without metal parts, reducing the risk of allergic reactions.

VitalSleep offers a more affordable, thermoplastic option that can be molded at home. While not as durable as custom-made alternatives, it provides a good entry point for those wanting to try an MRD before investing in a higher-end model.

Benefits and Limitations of Mandibular Devices

The primary benefit of Mandibular Repositioning Devices is their effectiveness in treating mild to moderate obstructive sleep apnea without requiring electricity or hoses. Studies show that properly fitted MRDs can reduce apnea events by 50% or more in suitable candidates. Many users report immediate improvements in sleep quality, reduced snoring, and better daytime alertness.

MRDs are also highly portable, making them ideal for travelers who find CPAP machines cumbersome. The devices are discreet, silent, and don't require a power source, giving users more freedom while maintaining treatment compliance.

However, these devices do have limitations. Some users experience temporary jaw discomfort, excessive salivation, or dry mouth, especially during the adjustment period. Long-term use may occasionally lead to dental changes, such as slight shifts in bite alignment. MRDs are also less effective for severe sleep apnea cases where CPAP therapy might be necessary.

Another consideration is that most insurance companies require a sleep study diagnosis before covering an MRD, and even with insurance, out-of-pocket costs can be significant compared to over-the-counter alternatives like Zyppah or SnoreRx.

Cost and Insurance Considerations

The price range for Mandibular Repositioning Devices varies significantly based on type and customization level. Custom-fitted devices from dental professionals typically range from $1,000 to $3,000, reflecting the precision craftsmanship and professional services involved. These devices are made from impressions of your teeth and adjusted specifically for your mouth structure.

Over-the-counter options like those from Good Morning Snore Solution cost between $80 and $200. While more affordable, these boil-and-bite devices offer less precision and may not be as comfortable or effective as custom solutions.

Insurance coverage varies widely. Medicare may cover MRDs when prescribed for obstructive sleep apnea with proper documentation. Private insurance typically requires a formal sleep study diagnosis and prescription. Many plans classify these devices as durable medical equipment rather than dental appliances, which affects coverage parameters.

When considering cost, factor in the device's lifespan. Custom devices typically last 3-5 years with proper care, while over-the-counter options may need replacement after 6-18 months. This durability difference can offset the initial price gap when calculated as a cost-per-night over the device's lifetime.

Conclusion

Mandibular Repositioning Devices offer a valuable alternative for those who struggle with sleep apnea but find CPAP therapy challenging. While not suitable for everyone, particularly those with severe sleep apnea or significant dental issues, MRDs provide an effective solution for many patients. The technology continues to improve, with newer models offering better comfort and adjustability. Before purchasing, consult with both a sleep specialist and dental professional to determine if an MRD is appropriate for your specific condition. With proper selection and consistent use, these devices can significantly improve sleep quality and overall health for many sleep apnea sufferers.
