Outstanding results from your local orthodontist
“I was referred from my dentist for Invisalign. I can’t thank Catherine, and all of her team, enough for everything they have done. Catherine reviewed my scans weekly and saw me regular to make sure everything was on track. Zoe worked wonders on the composite bonding and Helen and Gail attached my fixed retainers perfectly. I would 100% recommend St Michael’s for any orthodontic treatment.”

The iTero scanner
A unique part of the clear aligner treatment journey is the iTero scanner. This advanced piece of equipment allows us to get a better view of your teeth and plan your orthodontic treatment with precision. The scanner painlessly scans your whole mouth and then creates a digital rendering of your teeth. Each tooth can then be tracked individually, allowing us to create an optimised treatment plan.

Frequently asked questions
Who is the ideal candidate for clear aligners?
The best candidate for clear aligners is someone with mild to moderate tooth misalignment, crowding, or gapped teeth. Screening for gum disease and decay is essential, as treatment should be delayed if there is an active infection.
How do clear aligners work?
The clear aligner systems utilises a series of translucent removable, moulded trays that position teeth using gentle pressure. Each set of aligners is shaped slightly differently than the previous one, nudging specific areas throughout your bite.
Is there an age limit for clear aligners?
Clear aligners were initially meant for adult orthodontic patients. However, responsible teens may also qualify for clear aligners. There is no age limit to clear aligners.
Are clear aligners better than other types of orthodontics or braces?
For our patients searching for a subtle, convenient way to strengthen their teeth, clear aligner systems are the clear leader; especially if you want to avoid traditional orthodontic designs. Functionally, clear aligners tend to be just as effective at managing mild to moderate tooth misalignment as conventional braces.
