What is Invisalign?

Invisalign is the clear and virtually invisible solution for straightening your teeth – for adolescents, teens and adults.

Invisalign is a virtually invisible treatment that uses an innovative approach to gently yet effectively straighten your teeth.

Through a series of custom-made, removable aligners that look like a thin, clear mouthguard, Invisalign gradually and gently moves your teeth to an ideal position. Invisalign clear aligners are clinically proven to treat minor teeth straightening through to moderate and severe malocclusions.

Along with the clear aligners you may have buttons, attachments and elastics as part of your treatment. Why they are an important part of your treatment has been detailed here.

How does Invisalign work?

When you begin Invisalign treatment, you wear one aligner per week (or per fortnight – depending on your treatment plan) until you have worn your entire set of aligners. The number of aligners you need to wear will depend on your treatment plan.

Each week you scan into the Dental Monitoring app. Dental Monitoring uses artificial intelligence to track your teeth movement. These scans are analysed by Dr De Angelis and our team to work out if the teeth have moved sufficiently for that week, in accordance with your treatment plan.

Within 12 hours from your scan, you’d expect to get a message within the app to say you can proceed onto your next set of aligners – this is a ‘GO‘. Or you will be advised to stay in your current aligner for a bit longer (so your teeth have a bit more time to move into the required position) – this is a ‘NO GO‘.

Together with tracking your progress on Dental Monitoring, you will come in for regular in clinic appointments so we an ensure your treatment is going as planned. At those appointments you’ll see Dr De Angelis and the entire team.

After an initial consultation, we will create a customised 3D treatment plan based on your records. This will allow you to view the final predicted position of your teeth. It will also allow us to inform you of the likely length of your treatment.

The customised aligners will then be manufactured and shipped to us to fit, before we hand them over for you to wear every day, and change as prescribed.

You will only need to visit us approximately every six to eight weeks to monitor your progress.

Everything you need to know about Invisalign has also been detailed here in our blog post.

What are the advantages of Invisalign treatment?

  • Invisalign aligners are removable, making it easier to eat, brush and floss.
  • Invisalign treatment may give you visible results from as early as the first month of treatment.
  • Virtually invisible, very few people would notice you’re having your teeth straightened with Invisalign.
  • With no metal brackets cutting your mouth, Invisalign are known as being a more comfortable way of straightening your teeth.
  • Orthodontic visits are only needed approximately every 6-8 weeks.

Once I start Invisalign treatment, what do I need to do?

You will only need to visit us in one of our Adelaide clinics approximately every six to eight weeks thanks to our ability to monitor your progress via Dental Monitoring. This is fantastic for the busy lifestyles we lead as it means less in-clinic appointments!

Fewer appointments and faster treatment time, the Dental Monitoring app allows you to receive instant feedback from Dr De Angelis on a weekly basis.

There may be instances where we only need to see you every 12 weeks if your treatment is tracking well via the Dental Monitoring app.

How do I get the best results with my Invisalign treatment?

Here are our top tips!

  • Wear each aligner for 22 hours a day during your treatment for best results and a timely outcome.
  • Yes you can eat ice cream with Invisalign! You can eat what you want while in treatment because the Invisalign aligners are removed when eating or drinking. This means you don’t need to refrain from your favourite foods and drinks. However, it’s recommended that you floss and brush your teeth after each meal and prior to re-inserting your aligners to maintain proper oral hygiene.
  • You can drink water with your aligners in however, we recommend that you avoid drinks such as coffee, tea, wine and beer while wearing the aligners. This is to avoid cavities and stains forming on your teeth, or warping your aligners with hot beverages. Rule of thumb is water is OK with aligners in but for every other drink, take your aligners out.
  • We recommend no smoking while wearing aligners because it’s possible for them to become discoloured.
  • If you love your chewing gum we recommend removing your aligners as the gum may stick to them.
  • Visit us for a check-up approximately every 6-8 weeks to see how your treatment is progressing. During your check-ups, we will check that the aligners are fitting well and make any adjustments if necessary.
  • Some people might experience temporary, minor discomfort for a few days at the beginning of each new stage of treatment. This is normal and is typically described as a feeling of pressure. It’s a sign that the Invisalign aligners are sequentially moving your teeth to their final positions. This discomfort usually goes away a couple of days after you insert the new aligner in the series.
  • If you notice a sharp pain or have significant discomfort, stop using the aligners and please contact us on 133 862.

Invisalign clear aligner treatment starts working from the very moment you place your first set of aligners on your teeth! You may not notice the movement as Invisalign is designed to move your teeth very gently and slowly which is the safest and best way to move your teeth into their ideal position.

Do your teeth move back after clear aligner treatment?
Search Open
Did you know that your teeth have a memory? It’s true! Your teeth may try to move back into their original position after your orthodontic treatment. This is why wearing a retainer after your braces or clear aligner treatment is so important. Retention is critical to ensure that your teeth will look as good in years to come, as they do on the day your braces (or clear aligners) are removed. This makes the retention phase of orthodontic treatment (that immediately follows competion of braces or clear aligner treatment) really important. A retention program is individually tailored for each patient and involves a fixed bonded lingual wire and removable retainers. These retention appliances are designed simply to hold the teeth in place once braces are removed and are generally not visible, and very simple to wear and maintain. We talk to all new patients about retention at their first initial consultation.

You will soon get used to the aligners and you will notice you won't have a lisp when you do!

Is Invisalign or Spark better than braces?

Braces and clear aligners both move gently teeth into their desired position but it really comes down to personal preference. Invisalign and Spark clear aligners are very popular as they are almost invisible and they can be taken out for meals, for events and when playing sports. On the other hand though, braces don't need to be taken off at all so they are great for people who don't think they would be able to wear aligners for 22 hours per day.
