An Improper Bite

An improper bite, or a malocclusion, not only affects appearance but can also indicate jaw dysfunction or problems with underlying bone structure, including overbite, underbite, cross-bite, and crowded or impacted teeth.

This field of dentistry is most commonly associated with retainers and with a specialised dental apparatus known as dental braces. There are several kinds of braces, including Invisalign® clear aligners and traditional metal braces. They all have the same purpose: to gradually move the teeth into the desired position.

All orthodontic treatments can be carried out either by a general dentist or by a specially qualified orthodontist. Learn more about the difference in treatment from a general dentist and specialist orthodontists by reading the recommendations from the Australian Society of Orthodontists.

To qualify as a registered specialist orthodontist in Australia, practitioners must first have the same degree as a general dentist, with honours. They then study for a further three to four years for a Masters degree or equivalent specific training in orthodontics, making them eligible to apply for registration with the Dental Board of Australia as a specialist orthodontist.

Our Orthodontists

Our orthodontists often work in seamless collaboration with paedodontists in cases involving children’s teeth and with prosthodontists and cosmic dentists in cases involving adult oral health and restoration.

Never assume that an orthododontist is a registered specialist; always check on the website of the Australian Health Practitioner Regulation Agency (AHPRA).

When you are seen by a registered specialist orthodontist you can be assured that they are fully qualified to meet your particular orthodontic needs.

Our team of orthodontists comprises registered specialists Dr Martin Poon, Dr David Austin, Dr Andrea Phatouros, and Dr Steven Bajada.

You don’t need a referral to see any of our orthodontists. Please call us on (03) 9650 2726 to discuss your needs and make an appointment. We look forward to being of service to you.
