Invisible Aligner Therapy

Aligners are nearly invisible and look similar to clear tooth-whitening trays, but are custom-made for a better fit to move teeth. Some orthodontists have referred to them as “contact lenses for teeth”.

The length of treatment is dependent on the severity of individual cases. Treatment may vary from anywhere between six months to two years with an average treatment taking around 12 to 14 months.

There are over 890,000 patients being treated with Invisalign and the number grows daily. Invisalign was launched in Australia in February 2002 and already over five hundred Australian orthodontists and dentists are accredited to treat patients with Invisalign.

While Invisalign can be used with virtually any treatment philosophy, specific training is needed. All orthodontists and dentists interested in treating patients with Invisalign must attend a training course before cases will be accepted from their office.

Like brackets and arch wires, the Invisalign aligner moves teeth through the appropriate placement of controlled force on the teeth. The principal difference is that Invisalign not only controls forces, but also controls the timing of the force application. At each stage, only certain teeth are allowed to move, and these movements are determined by the orthodontic treatment plan for that particular stage. This results in an efficient force delivery system.

If your insurance policy has orthodontic coverage, Invisalign should be covered to a similar extent as conventional braces as Invisalign is normally prescribed for a full course of orthodontic treatment. However, as medical benefits differ significantly from policy to policy, each patient should check with their health fund.

Invisalign is an emerging form of technology within orthodontics in Australia. It often takes insurance companies to formally recognise new technologies in their policies. Please consult your treating orthodontist/dentist to ascertain the type of treatment you will be receiving and determine their billing policies in relation to private medical insurance. Invisalign Australia can provide assistance if necessary.

Invisalign is an effective at straightening teeth as tradition methods of orthodontics but largely depends upon a patient’s biology and compliance with treatment. As such, Invisalign cannot guarantee that a patient’s teeth will move exactly as predicted.

The treating orthodontist or dentist is responsible to use their experience and skill to treatment plan and monitor the appropriate treatment as it progresses. If necessary, additional treatment with Invisalign or other forms may be needed. Discuss this further with your treating orthodontist or dentist during your initial consulation.

Yes. There is a government rebate that is available to a taxpayer whose eligible net medical expenses in the year of income exceed $1,500 (net of Medicare and any health fund refund). The amount of the rebate is 20% of the excess over $1,500 but cannot exceed the amount of tax otherwise paid. The rebate is claimed when the patient lodges their annual income tax return.

For example, a patient undergoes Invisalign treatment at a cost of $6500. Assuming the patient can claim $1000 back from a private health fund and none from Medicare, the rebate would be as follows.

[($6500-$1000-$0) – $1500] x 20% = $800

Invisalign does not treat patients. Orthodontists and dentists do, and with experience they can use Invisalign to treat a vast majority of adults and adolescents who want a better smile.

Align Technology defers to the professional judgment of the treating doctor in determining how Invisalign can be incorporated into the treatment plan. Align Technology almost never rejects the cases submitted by our doctors, as we currently accept over 98% of all cases we receive but only a orthodontist or dentist who has been Invisalign accredited can determine if

Invisalign is an effective option for you.

Only the treating orthodontist/dentist is able to determine whether your particular case is suitable to be treated with Invisalign. Three types of tooth movements have found to be less predicably achieved with Invisalign alone:

• Severe derotations of cylindrical teeth
• Complex extrusions
• Closure of large spaces usually associated with extractions of teeth other than lower inscisors.

With more Invisalign experience, doctors may improve the ways they manage the treatment and increase the predictability of these movements.

Almost all teenagers over the age of 14 are eligible for treatment with Invisalign as long as their second (twelve year old) molars are fully erupted.

Many patients are being treated with some form of combination of braces and Invisalign. You should consult with your orthodontist or dentist to determine the best treatment for you.

Yes, Invisalign can correctly mild to moderate overbites. The aligners create a force on the front teeth causing them to intrude, thus correcting the overbite.

Yes, certain dental conditions can restrict you from being an eligible patient – for further information, please consult your orthodontist or dentist. Cases that are difficult or unsuitable for Invisalign may exclude up-righting severely tipped teeth, cases where not all the permanent teeth have erupted, cases with multiple missing teeth, patients with poor periodontal condition or patients that want to change their facial profile.

No, crowns are usually not a factor in Invisalign treatment. However, small composites called attachments are sometimes bonded onto teeth to help achieve certain movements. In these cases, the location of crowns must be carefully evaluated by an Invisalign orthodontist or dentist.

TMJ refers to the temporomandibular, or jaw joint. Individuals can have a number of problems with the jaw joint, some of which can be aggravated by appliances and treatments like Invisalign. To find out if your TMJ problem will adversely impact orthodontic treatment consult an Invisalign accredited orthodontist or dentist.

Yes. Spaces between teeth are generally easy to close with Invisalign. However, the size and location of the spaces will need to be evaluated.

Because bridges firmly link two or more teeth together, they can offer significant resistance to tooth movement. Your orthodontist or dentist will be able to determine whether bridges will be a factor in your treatment.

After or during the initial consultation, your treating orthodontist/dentist will need to take x-rays, photos and moulds of your teeth. These records will be sent to the US to be used to manufacture your custom made aligners. This process will take approximately 6 weeks (from the time the records are sent to the US to the time treatment can begin).

Your orthodontist or dentist will schedule regular appointments – usually about once every six weeks. This is the only way your orthodontist or dentist can be sure that the treatment is progressing as planned.

Most people 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 is a sign that the Invisalign aligners are working – sequentially moving your teeth to their final destination. This discomfort typically goes away for a couple of days after you insert the new aligner in the series.

Like all orthodontic treatments, aligners may temporarily affect the speech of some people, and you may have a slight lisp for a day or two. However, as your tongue gets used to having aligners in your mouth, any lisp or minor speech impediment caused by aligners should disappear.

No. Unlike traditional orthodontics, you can usually eat whatever you desire while in treatment because you remove your aligners to eat and drink. Thus, there is no need to restrict your consumption of any of your favourite foods or snacks, unless instructed otherwise by your orthodontist or dentist. Also, it is important that you brush your teeth after each meal and prior to re-inserting your aligners to maintain proper hygiene.

You should remove your aligners to drink anything else except water. Leaving aligners on while drinking may stain them and the patient risks decay drinking fluids with sugar in them.

We discourage smoking while wearing aligners because it is possible for the aligners to become discoloured.

No, gum will stick to the aligners. We recommend removing your aligners for all meals and snacks.

The best way to clean your aligners is by brushing and rinsing them in lukewarm water. Your treating doctor can also supply you with aligner cleaning crystals.

Aligners should be worn all day, except when eating, brushing and flossing.

While we are aware that some patients are using aligners for bleaching, Align Technology, Inc. Has not examine the compatibility of currently available bleaching products with our aligners, nor have we demonstrated efficacy in clinical studies. Align recommends that you consult your orthodontist or dentist for more information on whitening teeth.

This depends on the outcome of the treatment. Some patients might need a positioner, or conventional retainer. Other patients might need a clear plastic retainer similar to Invisalign aligners. Discuss these possibilities with your treating orthodontist or dentist. Every patient is different and outcomes vary.

In this case you should contact your orthodontist or dentist immediately who will diagnose what remedial action is needed to bring the treatment back on course. This may involve moving back one or two stages in treatment to a previous aligner or possibly some additional orthodontic treatment.
