Occlusal Splints

Occlusal splints are generally recommended for people who grind or clench their teeth: a condition called “bruxism”, and for people that have had extensive dental treatment due to bruxism.

What is bruxism?

Some people grind their teeth and clench their jaw muscles during their sleep. This is called bruxism and is an involuntary habit. Bruxism is a very common occurrence, and often individuals are not even aware of their habit as it commonly occurs during sleep. However, over the years the gradual wear of the teeth can amount to a serious situation.

How does bruxism affect  your teeth?

As bruxism causes the upper and lower teeth to wear against each other it leads to gradual shortening and chipping of the biting surfaces of your back teeth and the edges of your front teeth.

The pressure of the upper and lower teeth can also lead to the 'flaking away' of the enamel adjacent to your gums due to the pressure and flexing forces placed on your teeth when grinding. This causes notches that may be shallow and or sometimes very deep forming along your gumline which can become very sensitive to cold, acids and sweet or if inadequately cleaned, decay can occur.

Bruxism can also lead to strain and injury to the jaw joint (TMJ joint) and associated muscles. This can lead to pain, clicking or locking of the joint or muscular headaches.

What is an occlusal splint?

An occlusal splint is a slim hard acrylic guard fitted to the upper or lower jaw and covering the biting surfaces of your upper teeth. It is designed to be worn at night. An occlusal splint will not stop you from grinding or clenching. It does however, guide the jaw into a neutral position which relieves some of the pressure on the jaw joint and very effectively protects your teeth against the destructive forces of bruxism.

What to expect during your occlusal splint appointments?

As our occlusal splints are custom made specifically for you in Perth's laboratories, two short appointments are required:

  1. Impressions. During this appointment your dentist will take impressions of your upper and lower teeth

  2. Splint fitting. During this appointment your dentist will ensure that your new splint fits comfortably around your upper teeth and in your bite

Is further treatment necessary?

The purpose of a splint is to absorb the destructive forces of bruxism and to provide something to wear down other than your teeth. As such your splint will wear down, chip and may eventually break after years of grinding on it. When this occurs, your splint will need to be replaced.

In cases of severe bruxism in addition to an occlusal splint to protect your teeth, treatment by a physiotherapist may be necessary to address any muscular pain and to provide exercises to strengthen and protect your jaw joint.

Mandibular Advancement Splints (SomnoDent)

Sleep is the basis of good health, feeling well and being happy. Sleep gives your body and mind time to recover and rejuvenate

Sleep related breathing disorders such as Obstructive Sleep Apnea and Snoring disrupt restful sleep and over time they can have devastating effects on your health, work and relationships.

What is obstructive sleep apnea?

While you sleep your body relaxes and muscles soften, the tongue can drop back and reduce airflow as you breathe. The soft tissue may vibrate as air tries to rush into your lungs and this causes you to snore.

If you have obstructive sleep apnea your airway periodically closes over and prevents air from getting to your lungs while you sleep. An apnea can last from 10 seconds and in severe cases over a minute in duration. Numerous apneas throughout the night cause sleep disturbance and put strain on your heart.

One of the treatment choices your doctor can prescribe is a custom made Mandibular Advancement Splint such as SomnoDent. It is worn over your teeth and holds your lower jaw forward, which opens your airway.

How do I know if I have obstructive sleep apnea?

Keys signs and symptoms are:

  • Excessive snoring

  • Partner notices you stop breathing

  • Choking or gasping during sleep

  • Frequent visits to the bathroom during the night

  • Daytime tiredness

  • Lack of energy

  • Poor concentration/memory

  • Falling asleep during the day

What are the consequences?

  • Relationship breakdown

  • Partner sleeping in separate room

  • Impact on your career

  • Increased risk of: Heart Attack, Stroke, Type 2 Diabetes, Increased Blood Pressure, Motor Vehicle Accidents

How does SomnoDent help?

SomnoDent is recommended for use in patients with Snoring and mild to moderate Obstructive Sleep Apnea or in more severe cases where CPAP treatment is not tolerated. It is a custom fitted dental device worn while you sleep that fits over your upper and lower teeth and is designed to keep your airway open by holding your lower jaw and tongue base forward.

SomnoDent is comfortable, discreet and easy to use.

Why should you have a custom made device fitted by a dentist?

Comfort and the ability for the device to stay in place are critical in treatment success. Clinical research has proven custom fitted devices are much more effective than cheap "one size fits all" devices sold online and over the counter. You will be wearing your device every night for a long time, and this device is an investment in your health. So you want to make sure it fits properly and works effectively to give you a good night's sleep.

What to expect during your SomnoDent appointments?
