Invisalign is the invisible new way to straighten teeth without braces. Invisalign uses a series of clear, removable aligners to gradually straighten teeth, without metal or wires. It combines 21st century technology and revolutionary manufacturing to customise a treatment for each individual patient.
Yes. In both clinical research and in dental practices around the world, Invisalign has been proven effective at straightening teeth. Over three million patients have either been treated, or are in treatment, and thousands of dental professionals have been trained on how to use Invisalign.
Invisalign uses 3-D computer imaging technology to depict the complete treatment plan, from the initial position to the final desired position, from which a series of custom-made “aligners” are produced. Each aligner moves teeth incrementally and is worn for about two weeks, then replaced by the next in the series until the final position is achieved.

There are four primary benefits:

  • Invisalign is nearly invisible – you can straighten your teeth without anyone knowing.
  • Invisalign is removable – you can eat and drink what you want in treatment; you can also brush and floss.
  • Invisalign is comfortable – there are no metal brackets or wires to cause mouth irritation.
  • Invisalign allows you to view your own virtual treatment plan before you start – so you can see how straight your teeth will look when your treatment is complete.
Aligners are made of clear, strong medical grade non-toxic plastic that is virtually invisible when worn.
Aligners are nearly invisible and look similar to clear tooth-whitening trays, but are custom made for a better fit to move teeth. Some dentists have referred to them as “contact lenses for teeth”.
The length of treatment is dependent on the severity of the individual case. Treatment may vary from anywhere between 6 months to two years, with an average treatment taking around 12 to 14 months.
To date, there are over three million patients that have been treated with Invisalign and the number grows daily.
While Invisalign can be used with virtually any treatment philosophy, specific training is needed. All dentists interested in treating patients with Invisalign must attend a training course before they can begin treating patients.
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.
As is typical of medical product introductions, Invisalign conducted extensive testing prior to commercially releasing the product. Various US universities have conducted clinical studies and numerous clinical articles have been published by US and Australian dentists.
Invisalign is a premium product compared to traditional braces. It uses state of the art technology to create a series of customised aligners for each patient and has significant patient benefits. The cost of treatment is based upon the complexity of treatment required and the schedule of fees charged. Invisalign treatment is usually similar or slightly more than the cost of adult ceramic braces. Depending on individual circumstances, Signature Dental can offer ways to manage any financial concerns you may have and does offer payment plans for patients having Invisalign.
In most cases, there will be an initial consultation fee charged by Signature Dental. Please contact our friendly staff at Signature Dental to discuss this further.
The charge for Invisalign is based upon the consultation needed and the 3D modelling cost. Single arch treatment does not mean that the price will necessarily be halved from the two arch treatment cost. If you believe that you only need top/bottom aligners, the best starting point would be to arrange a consultation at Signature Dental. Once we have discussed your particular requirements and considered your smile and bite, we can give you a better idea if this will be a suitable treatment for you.
Invisalign can be used to provide a limited form of orthodontic treatment e.g. orthodontic relapse or minor crowding cases for a lesser fee. Please discuss this further with Dr Allison Kale during your dental consultation.
Invisalign is as effective at straightening teeth as traditional methods of orthodontics but largely depends upon the patient’s biology and compliance with treatment. As such, Invisalign or Signature Dental cannot guarantee that patient’s teeth will move exactly as predicted. If necessary, additional treatment with Invisalign or other methods may be needed.
You may be eligible to obtain a rebate from your Private Health Insurance fund for Invisalign treatment. Some eligible patients are also able to obtain a tax rebate for a portion of their dental care. It is best to seek advice from your accountant to check if you are eligible.
The skilled and accredited staff at Signature Dental will be able to determine if Invisalign is an effective option for you. Please give us a call and arrange an appointment for a consultation with Dr Allison Kale. She will be able to assess your teeth and bite, let you know if you are a suitable candidate and answer any questions you may have.

Three types of tooth movements have found to be less predictably achieved with Invisalign alone

  • Severe derotations of cylindrical teeth
  • Complex extrusions
  • Closure of large spaces usually associated with extraction of teeth other than lower incisors
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.
Yes, certain dental conditions can restrict you from being an eligible patient – for further information please contact the friendly staff at Signature Dental to arrange a consultation to see if you are eligible. Cases that are difficult or unsuitable for Invisalign may include up-righting severely tipped teeth, multiple missing teeth, cases where teeth have not erupted, cases with multiple missing teeth, patients with poor periodontal health 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 the crowns must be carefully evaluated by Signature Dental. Dr Kale will assess your teeth and discuss options for your treatment plan in relation to Invisalign and your existing crowns.
TMJ refers to the tempromandibular, 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, book a consultation with Signature Dental.
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. During your consultation the staff at Signature Dental will be able to determine whether bridges will be a complicating factor in your treatment. Dr Kale will assess your teeth and discuss options for your treatment plan in relation to Invisalign and your existing bridgework.
After or during the initial consultation, the staff at Signature Dental 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 moulds are taken of your teeth).
We will schedule regular appointments – usually about one every four to six weeks. This is the only way we can be sure that the treatment is progressing as planned.

It has been reported that the pain is nothing like the pain experienced in normal fixed braces, most people experience temporary, minor discomfort for a few days at the beginning of each new stage of treatment. This is normal and typically described as the feeling of pressure. It is a sign that the aligners are working – sequentially moving your teeth to their final destination. This discomfort typically goes away a couple of days after you insert the new aligner in the series. We can advise you of the best way to manage and concerns you have in relation to discomfort during your orthodontic treatment.

Like all orthodontic appliances, 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 the aligners in your mouth, any lisp or minor speech impediment caused by the aligners should disappear. If you have any further concerns, please discuss with Dr Allison Kale.
No. Unlike traditional orthodontics with braces, 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 and snacks, unless instructed otherwise by Signature Dental. Also, it is important that you brush your teeth after each meal and prior to reinserting your aligners to maintain proper oral hygiene.
You can drink cold water whilst wearing your aligners. However, you should remove your aligners to drink anything other than water. Leaving the aligners in place whilst drinking fluids containing sugar may cause dental decay.

We discourage smoking while wearing aligners because it is possible for the aligners to become discoloured. If this is a concern please discuss this further with Dr Allison Kale.
No, gum will stick to the aligners. We recommend removing your aligners for all meals and snacks.
Most people clean their aligners with a toothbrush, toothpaste and water, just like your natural teeth. The staff at Signature Dental can also suggest other forms of cleaning aligners if you need it.
Aligners should be worn all day, every day, except when eating, brushing, or flossing.
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. Every patient is different and outcomes vary and we are happy to discuss your particular needs with you during your consultation at Signature Dental.

The care with which Signature Dental prepares for the manufacturing process ensures that this does not happen. IF it does occur it is usually only because the aligners are not being worn correctly or for the appropriate amount of time. In this case you should contact Signature Dental immediately we 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.
