About

Splints

A splint, also known as an occlusal splint or nightguard, is a custom-made dental device designed to help alleviate symptoms of teeth grinding (bruxism) or temporomandibular joint (TMJ) disorders. It is typically made of acrylic and fits over either the upper or lower teeth, creating a barrier between the upper and lower jaws.

Why might I need

Splints

?

Splints help reduce the effects of clenching or grinding by providing a cushioning effect, promoting muscle relaxation, protecting teeth from wear and damage, and helping to realign the jaw joint for improved comfort and function.

Different approaches to

Splints

There are different types of splints for difference purposes:

Advancement for sleep apnoea

A mandibular advancement splint (MAS) is a type of oral appliance that is custom-made to fit over the teeth. It works by repositioning the lower jaw slightly forward during sleep, which helps open the airway by preventing airway collapse, and promote better airflow, reducing snoring and improving symptoms of obstructive sleep apnea.

Splint for grinding/clenching

A splint for grinding and clenching, also known as a nightguard, creates a barrier between the upper and lower teeth, absorbing the forces exerted during grinding or clenching. It helps reduce tooth wear, jaw muscle tension, and associated symptoms by promoting a more relaxed jaw position and preventing direct contact between the teeth.

What is involved for

Splints

The process of fabricating a splint involves:

1

Consult and diagnosis

Consultation with your dentist is important to ensure your splint is correctly designed to help with your condition. Splint designs can vary significantly depending on the goals of treatment, such as jaw pain, protection of teeth, or jaw repositioning. If you or your dentist suspect that sleep issues may be a problem, you may be referred for a sleep study to assess for other sleep disorders such as obstructive sleep apnoea.

2

Records

Once you have been assessed for a splint, your dentist will take several records of your teeth for the splint to be manufactured. These include measurements of your jaw, photos and scans of your jaw. These records are sent for your custom splint to be manufactured.

3

Fitting of appliance

When your custom splint is received, your dentist will ensure that it fits comfortably without excessive pressure, checking that your jaws are balanced while wearing your splint, as well as adjusting it to accomodate for your grinding patterns. These adjustments may need to be performed every few months, so it is important to bring your splint to your regular dental visits.

4

Care and maintenance instructions

Your dentist will discuss and demonstrate the correct care and cleaning methods for your splint. If a mandibular advancement splint has been provided, your dentist will also demonstrate how to adjust the appliance at home. These instructions will allow your splint to remain as clean, effective and long lasting as possible.
