Snoring and sleep apnoea affect millions of people worldwide, disrupting sleep quality and overall health. Snoring can be a nuisance, but it may also indicate underlying issues such as obstructive sleep apnoea (OSA), a condition where breathing repeatedly stops and starts during sleep. Poor sleep due to these conditions can lead to fatigue, cognitive impairment, and an increased risk of serious health complications like heart disease and stroke.
Mandibular Advancement Splint (MAS) therapy is an effective, non-invasive treatment designed to alleviate snoring and sleep apnoea by keeping the airway open during sleep. This article explores the benefits of MAS therapy, how it works, and why it is a reliable alternative to other treatments.
Understanding Sleep Apnoea and Snoring
What is Sleep Apnoea?
Sleep apnoea is a disorder in which breathing stops periodically during sleep due to airway obstruction or brain signal issues. There are two main types:
- Obstructive Sleep Apnoea (OSA): The most common form, caused by the relaxation of throat muscles that block airflow.
- Central Sleep Apnoea (CSA): A less common condition where the brain fails to send signals to muscles controlling breathing.
During sleep, particularly in deeper stages, the muscles in the throat naturally relax. In individuals with OSA, this relaxation can cause the tongue and soft tissues at the back of the throat to collapse and obstruct the airway. When airflow is blocked, oxygen levels drop, triggering the brain to send an alert. This often results in clenching of the jaw or even a sudden jolt awake as the body struggles to reopen the airway. This cycle can repeat multiple times per night, preventing the individual from reaching deep, restorative sleep. Over time, this disruption leads to excessive daytime sleepiness, poor concentration, and an increased risk of other health conditions associated with poor sleep quality.
Causes of Snoring and Sleep Apnoea
Several factors contribute to snoring and sleep apnoea, including:
- Anatomical issues such as a narrow airway or enlarged tonsils
- Obesity, which adds pressure to the airway
- Nasal congestion and sinus problems
- Sleeping position, particularly lying on the back
- Alcohol consumption and sedative use before bedtime
Health Risks Associated with Untreated Sleep Apnoea
If left untreated, sleep apnoea may lead to or worsen other health issues:
- High blood pressure
- Cardiovascular diseases
- Increased risk of stroke
- Daytime fatigue and reduced cognitive function
- Type 2 diabetes
What is MAS Therapy?
Definition of Mandibular Advancement Splint (MAS) Therapy
Mandibular Advancement Splint (MAS) therapy is a widely used treatment for individuals with snoring and mild to moderate obstructive sleep apnoea. It is an excellent alternative also for people who are unable to tolerate CPAP therapy effectively, particularly if they have severe OSA. It is an oral appliance designed to hold the lower jaw (mandible) in a slightly forward position during sleep. By repositioning the jaw, MAS therapy helps prevent the collapse of soft tissues in the throat to maintain an open and unobstructed airway throughout the night.
MAS devices are custom-made by dental sleep therapists to fit comfortably over the upper and lower teeth. Unlike over-the-counter mouthguards, professionally fitted MAS devices are adjustable, allowing for fine-tuning for better effectiveness. These devices are made from high-quality, durable materials designed for long-term use.
One of the key benefits of MAS therapy is its simplicity. Unlike CPAP machines that require air pressure and masks, MAS devices work naturally with the body’s anatomy. They are easy to wear, non-invasive, and well-tolerated by most users. In addition to treating snoring and sleep apnoea, MAS therapy may also alleviate symptoms of temporomandibular joint (TMJ) disorders and teeth grinding (bruxism), which often coexist with sleep-disordered breathing.
How It Works
The MAS device repositions the lower jaw, pulling the tongue and soft tissues forward. This keeps the airway open and reduces the likelihood of obstruction, improving airflow and reducing snoring and apnoea events.
Who Can Benefit from MAS Therapy?
MAS therapy is ideal for individuals with mild to moderate obstructive sleep apnoea and chronic snoring. It is also especially beneficial for those who cannot tolerate CPAP (Continuous Positive Airway Pressure) therapy and who have severe OSA.
How Does MAS Therapy Help in Treating Snoring and Sleep Apnoea?
Opening the Airway Naturally
By repositioning the jaw, MAS therapy prevents airway collapse without the need for forced air. The forward positioning of the lower jaw reduces airway resistance and increases airflow to promote a smoother breathing process during sleep.
Preventing Airway Collapse During Sleep
MAS therapy stabilises the structures in the throat, reducing the likelihood of obstruction. By advancing the lower jaw, the therapy creates more space at the back of the throat to help prevent the soft palate and tongue from collapsing into the airway. This stability may allow for uninterrupted breathing and reduced sleep disturbances.
Reducing Snoring Intensity and Frequency
Snoring occurs due to vibrations of soft tissues in the throat caused by restricted airflow. By holding the lower jaw forward, MAS therapy helps minimise these vibrations, significantly reducing both the intensity and frequency of snoring. This may lead to quieter and more restful nights for both the user and their sleep partner.
Improving Oxygen Intake and Sleep Quality
With better airflow, oxygen levels in the blood remain stable throughout the night. This helps prevent the frequent awakenings and fragmented sleep associated with sleep apnoea. As a result, individuals using MAS therapy experience deeper, more restorative sleep, leading to increased energy levels, improved mood, and better overall health.
Benefits of Using MAS Therapy
- Non-Invasive Alternative to CPAP Machines – Unlike CPAP, MAS therapy does not require a mask or air pressure, making it more comfortable. Many patients find CPAP machines cumbersome and difficult to tolerate, while MAS therapy offers a simpler and more user-friendly solution.
- Comfortable and Easy to Use – MAS devices are custom-fitted so that patients are more comfortable throughout the night. The design allows for natural jaw movement, making it easier to adjust to compared to other treatment methods.
- Portable and Travel-Friendly – Small and lightweight, MAS devices are easy to carry while travelling. Unlike CPAP machines, which require power sources and additional accessories, MAS therapy offers a hassle-free alternative for people who travel frequently.
- Long-Term Effectiveness – Regular use of MAS therapy leads to lasting improvements in sleep quality and overall health. It helps prevent long-term complications associated with sleep apnoea, such as cardiovascular disease and chronic fatigue. With consistent monitoring and adjustments by a sleep professional, MAS therapy may be an effective long-term solution for OSA.
- No Noise Disruptions – Unlike CPAP machines, which generate noise while operating, MAS devices are completely silent.
- Reduces Daytime Fatigue – By improving sleep quality and oxygen levels, MAS therapy helps reduce excessive daytime sleepiness, improving concentration and energy levels throughout the day.
MAS Therapy vs. Other Sleep Apnoea Treatments
- MAS vs. CPAP Therapy – MAS devices may be more comfortable and easier to maintain, leading to higher patient compliance.
- MAS vs. Surgery – Surgical procedures can be invasive and costly, whereas MAS therapy is non-invasive.
- MAS vs. Lifestyle Modifications – Lifestyle changes like weight loss and positional therapy also help in long-term sleep management; MAS therapy provides immediate, targeted relief. MAS therapy could be a primary treatment method supported by lifestyle modifications for better treatment outcomes.
Who Should Consider MAS Therapy?
- Ideal Candidates for Mandibular Advancement Splints – Individuals with mild to moderate sleep apnoea or habitual snoring can benefit from MAS therapy. It is also suitable for severe OSA patients who are unable to tolerate CPAP effectively.
- Medical Evaluation: Sleep Study and Dentist Consultation – A sleep study and consultation with a dental sleep professional are necessary to determine suitability.
- Cases Where MAS May Not Be Suitable – Patients with complex medical issues and OSA or severe dental issues may require alternative treatments.
How to Get a Mandibular Advancement Splint?
