Mandibular advancement splint (MAS) therapy is scientifically-proven as an effective and comfortable treatment for snoring and sleep apnoea. In more severe cases of sleep apnoea, a MAS is an alternative therapy for patients who struggle with positive airway pressure therapy.

MAS therapy is also ideal for people who feel unable to use their PAP machine while traveling, camping, etc.

How do mandibular advancement splints work?

Mandibular advancement splints are worn in the mouth to treat snoring and sleep apnoea. These devices are similar in some ways to orthodontic retainers or sports mouth guards. For this reason, mandibular advancement splints are also known as oral sleep appliances or dental sleep appliances.

The main way that mandibular advancement splints work is by preventing the tissues at the back of the throat and the base of the tongue from collapsing back into the airway while the patient sleeps. This is achieved by bringing the lower jaw (mandible) forward and stabilising it during sleep.

How are mandibular advancement splints made?

The ideal type of MAS are those made from impressions and models of the patient's own teeth. Some precise measurements using special instruments are also required to ensure that the appliances will fit properly and have the desired treatment effects.

Types of mandibular advancement splints

Whilst there are many different designs of MAS, there are two basic types:

·               Non-adjustable appliances - many available appliances are non-adjustable, making the ideal forward position of the jaw a guess.

·               Fully adjustable appliances - a fully adjustable appliance is far superior because it allows the lower jaw to be brought forward gradually until the ideal, most comfortable effective position is reached. Current scientific research demonstrates that adjustable appliance designs are by far the most effective.

Benefits of MAS therapy

ü             The patient and their partner can look forward to a quiet night of sleep.

ü             Less likely to produce embarrassing snoring sounds while traveling, camping or in any group situation.

ü             Wake up feeling refreshed rather than still sleepy or tired.

ü             Improved quality of life through greater vitality.

ü             Improved work performance due to greater concentration and energy levels.

ü             Decreased risk of fatigue-related vehicle and work accidents.

ü             Decreased risk of heart disease, stroke, high blood pressure, impotence and a host of other health problems.

An added benefit

Many people clench and grind their teeth while they sleep and are unaware that this is occurring. This condition, known as bruxism, is a common cause of damage to teeth and dental work. Mandibular advancement splints have the added benefit of protecting teeth and dental work during sleep.
