Mandibular Advancement Splints (MAS): The Recommended Treatment for Mild to Moderate OSA by the American Academy of Sleep Medicine (AASM)
Obstructive Sleep Apnea (OSA) is a sleep disorder that affects millions of people worldwide, leading to disrupted sleep patterns and a host of health issues. Fortunately, advancements in dental sleep medicine have introduced effective treatments, with Mandibular Advancement Splints (MAS) emerging as a recommended first-line therapy for individuals with mild to moderate OSA, and in severe OSA only when continuous positive airway pressure (CPAP) treatment fails or is refused [1]. According to the American Academy of Sleep Medicine (AASM), MAS offers significant benefits and advantages [2].
Mild-Moderate OSA (AHI < 30) = MAS first-line therapy
Severe OSA (AHI > 30) = MAS recommended for failed CPAP therapy
AHI= Apnea-hypopnea index (the official index for measuring OSA)
Understanding OSA
OSA occurs when the upper airway partially or completely collapses during sleep, leading to pauses in breathing. This can happen numerous times throughout the night, causing loud snoring, restless sleep, and daytime fatigue. OSA is classified into three categories: mild, moderate, and severe, based on the number of apnea or hypopnea events per hour.
The Role of AASM
the American Academy of Sleep Medicine is the only professional society dedicated exclusively to the medical subspecialty of sleep medicine in the USA.
As the leading voice in the sleep field, It is a renowned authority in sleep medicine, setting guidelines and standards for diagnosing and treating sleep disorders, including OSA. They consistently update their recommendations based on scientific research and clinical evidence to provide the most effective treatments to patients.
MAS: A Game-Changer for Mild to Moderate OSA
Mandibular Advancement Splints are custom-made dental appliances that patients wear during sleep. These devices work by repositioning the lower jaw slightly forward, which helps to keep the airway open and prevent airway collapse. Here's why MAS is the recommended treatment for mild to moderate OSA, as per AASM guidelines:
1. Proven Efficacy
Numerous clinical studies and research have demonstrated the effectiveness of MAS in reducing the severity of OSA. By improving airflow and reducing the frequency of apnea events, MAS helps patients enjoy more restful sleep.
2. Non-Invasive
Unlike Continuous Positive Airway Pressure (CPAP) machines, which involve wearing a mask and can be uncomfortable for some, MAS is a non-invasive and comfortable treatment option. Patients simply wear the custom-made splint in their mouths while sleeping.
3. High Compliance
One of the significant advantages of MAS is the high compliance rate among patients. Many individuals find it easier to adapt to wearing a dental splint compared to a CPAP mask, which can be bulkier and less comfortable.
4. Tailored Treatment
MAS is custom-designed for each patient, ensuring a comfortable fit and optimal results. Dentists specialising in dental sleep medicine carefully assess patients and create personalised devices that align with their unique needs.
5. Improved Quality of Life
Effective treatment with MAS not only reduces the symptoms of OSA but also leads to an improved quality of life. Patients report reduced daytime fatigue, increased alertness, and enhanced overall well-being.
In conclusion, Mandibular Advancement Splints have emerged as a recommended treatment option for mild to moderate OSA, backed by the American Academy of Sleep Medicine. Their proven efficacy, non-invasiveness, high compliance rates, personalised approach, and positive impact on patients' lives make MAS a valuable choice for those seeking relief from OSA symptoms and improved sleep quality. If you suspect you have OSA or have been diagnosed with mild to moderate OSA, consult with a qualified dentist specialising in dental sleep medicine to explore the benefits of MAS for your specific needs.
