What is a mandibular advancement splint (MAS)?
- A Mandibular advancement splint (MAS) is a dental device worn on the teeth during sleep similar to an orthodontic appliance.
- These devices can be used for treatment of snoring and mild to moderate sleep apnoea.
- The function of the splint is to push the lower jaw slightly forward, tightening the soft tissues and muscles in the upper airway preventing airflow obstruction during sleep which in turn will minimise snoring.
How does it work?
A dentist or orthodontist will assess the suitability of the MAS to determine if you are a good candidate to wear the device. Once assessment is made, the splint is created to custom fit the patient’s mouth in order to reposition the lower jaw (by about 8 to 10mm) to keep the airways open. Pushing the bottom jaw forward could be quite uncomfortable, but a properly fitted MAS should not cause any prolonged discomfort. The mandibular advancement splint is extremely safe and painless however, only a specialist qualified dentist trained in Dental Sleep Medicine can fit the device.
Does it hurt?
Some people may initially experience aching jaw muscles and teeth but should disappear after a few days as the mouth gets used to the dental device.
To slowly ease into the therapy, it is recommended that the splint be worn a couple of hours before going to bed for the body to get used to the device. Your dental sleep specialist will monitor and make any necessary adjustments to ensure that your device fits properly and comfortably into your mouth for best treatment.
At times, if the patient is unable to acclimatize to CPAP therapy, a MAS device may be recommended. To find out the best possible treatment for you, please contact us on 1300 800 357 and ask for one of our sleep clinicians.
How often do I need to change the MAS?
MAS splints are easy to take care of and can be cleaned with a toothpaste and toothbrush. Most mandibular devices may also be used for 4-5 years.
How would I know if MAS is right for me?
Different people have different facial structures and airways. As such, it is difficult to determine whether an oral appliance is appropriate for you therefore, a sleep study is necessary to initially assess your condition and if a MAS is a suitable treatment option for you. At The SleepHealth Clinic, we have professionally trained sleep specialists and clinicians working together with qualified dentists that will strive to find the best treatment method for you.
