What is Invisalign®?

Invisalign is a series of clear, removable aligners that are worn full time (except eating) and usually changed every 2 weeks. They work by sequentially moving the teeth into their straight positions.



I am seeking a better smile and am concerned about the appearance and discomfort of braces. How does the Invisalign® aligners compare with braces?

The Invisalign aligners are removed when eating thereby allowing maximum flexibility with eating. This differs from fixed braces where care with eating is required and hard foods have to be avoided or modified in the way they are eaten ie: cutting apples into wedges before they are consumed.

In addition, the Invisalign aligners are removed when cleaning your teeth, making this process a breeze compared to toothbrushing and using floss with braces.
Unlike braces, the Invisalign aligners do not have any projecting hooks, and are thinner than the width of the mini-braces that we use, so our patients universally find Invisalign to be a very comfortable appliance, more so than braces.


What are the effects on speech with Invisalign®?

There can be some slight speech changes with the ‘s’and ‘th’sounds after the Invisalign aligners are first fitted. This quickly returns to normal within a few days as the aligners mainly only cover your teeth surfaces and do not extend onto the gums. If you are concerned with this aspect, you may arrange to have the 1st series of the Invisalign aligners fitted at the end of your work week.

I have a wedding (or formal) planned and I really do not want to show my crooked teeth or braces on smiling. What teeth straightening options are there for me?

You no longer need to hide or feel embarrassed about your smile. Invisalign or hidden braces attached to behind your teeth would be the most suitable option for you. Occasionally, if you have that special occasion, you may take out the Invisalign aligner for the duration of that day’s occasion and reinsert it during sleeptime. This is not possible with braces.
With the Invisalign option, we are able to estimate at any particular point in time what your new smile will look like, prior to the actual Invisalign aligners being made. This is through the Clincheck- a computerized sequential projection of the planned teeth movements (see example below), which we will discuss with you to obtain your feedback, to discuss the position and duration of any tooth coloured attachments, elastics, projected outcome and the need for any auxiliary orthodontic treatment.

I am looking for a faster treatment time. What teeth straightening options are there for me?

You also may be interested in Accelerdent- a vibrating compact portable rechargeable mouthpiece which is worn for 20 minutes a day. Accelerdent is worn as an adjunct to any aligner or braces orthodontic treatment. Dr Chang is one of the few orthodontists in Sydney that is certified to offer this to our patients.
When combined with Invisalign orthodontic treatment, Accelerdent effectively allows you to cut down the wear of each Invisalignaligner from 2 weeks to 1 week. This can reduce your treatment time by as much as half. The direct benefit to you is a reduction in your treatment time.

Is Invisalign® as effective as braces?

This needs to be examined on a case by case basis. In certain cases, several metal or clear mini braces, mini-auxiliaries or a pre-Invisalign® appliance may need to be attached before treatment, during, or the end stages to enhance the movements. These are usually attached on the side teeth for up to 6 months. Combining these partial braces or auxiliaries with Invisalign treatment, allows us to shorten the overall duration of orthodontic treatment and expand the range of cases that can be treated with Invisalign orthodontic treatment.
This will be discussed with you at the initial consultation.
While the majority of cases can be treated with Invisalign, in a small proportion, braces is still a more predictable option. These include teeth which are unerupted and impacted, very short teeth, multiple missing teeth, or where large teeth movements are planned. Even in these instances, if you are an adult or require a need for discreetness, we have other options ranging from the outside clear braces to the hidden braces that are attached to behind your teeth.

What is the difference between seeing a dentist versus an orthodontist for Invisalign® orthodontic treatment?

Orthodontists receive an additional 3 years of specialised education, beyond dental school, to learn the proper way to straighten and align teeth. Orthodontists practice orthodontics and dentofacial orthopaedics exclusively. All orthodontists are dentists, but only 6% of dentists are orthodontists.
Is safety and security important for you when having your teeth straightened? Remember that it is often more costly in the long term trying to correct an incomplete bite or smile, asides from the prolonged orthodontic treatment time and energy spent, when your expectations cannot be met. If this is important for you, then perhaps you should see an orthodontist.

How do I know I am seeing an orthodontist?

Look for the seal of the Australian Society of Orthodontics (ASO). Only orthodontic specialists can belong to the ASO.
