Invisalign®

What is Invisalign^®?

Your Invisalign^®treatment consists of a series of aligners that you change about every two weeks. Each aligner is custom manufactured with exact calculations to gradually shift your teeth into place. And since your Invisalign^© system is custom-made for your teeth and your teeth only, with a plan devised by you and Dr. Pearce, you know you'll end up with a smile that truly fits.

What kind of bite problems can Invisalign^® correct?

Invisalign^® corrects the same dental problems as traditional metal braces; the only difference is that Invisalign^® trays are almost invisible to the naked eye, and can be removed at will.

Here are some problems that are commonly corrected with Invisalign^®:

• Overcrowding – This occurs when there is too little space for the teeth to align normally in the mouth.  Overcrowding can cause tooth decay and increase the likelihood of gum disease.
• Large gaps between teeth – This can sometimes occur because teeth are missing or because the jaw continues to grow abnormally.
• Crossbite – This common dental problem occurs when one or multiple upper teeth bite inside the lower teeth.  As a consequence, uneven wear can lead to bone erosion and gum disease.
• Overbite – This problem occurs when the upper teeth project further than, or completely cover, the lower teeth. 
  
• Underbite – This is the inverse of the overbite; the lower teeth project further than, or completely cover, the upper teeth. 
  

What advantages does Invisalign^® offer over traditional braces and veneers?

Traditional dental braces, Invisalign^® aligning trays and dental veneers are three different ways to perfect the alignment of the teeth.  There are many different considerations to make when considering which treatment will be best, and each of these options works better in certain situations.

Invisalign^® differs from traditional braces in that the aligning trays are fully removable.  This means that more discipline and commitment is required from the patient.  This is not usually a problem since the trays are comfortable and nearly invisible.  Almost identical results can be obtained by using either treatment.

Invisalign^® is preferable to veneers in many cases because unlike veneers, Invisalign^® actually straightens the teeth. Veneers are thin covers that the dentist affixes to the teeth.  In many cases teeth must be prepared beforehand, meaning that to remove dental veneers, an alternative covering must be constructed. However, veneers can change the shape , size and colour of your teeth, something braces or Invisalign^® cannot do. Sometime the best results are achieved with a combination of both treatments.

What does Invisalign^® treatment involve?

First, the dentist needs to devise an initial treatment plan before creating the special aligning trays.  Three-dimensional digital images are taken of the entire jaw.  These images allow the dentist to move specific teeth on the screen, view the jaw from different angles, and also foresee what the face might look like in years to come.  In essence, this technology can show how Invisalign^® trays will change the facial aesthetics.

Once planning is complete, a unique set of aligners is made.  The total amount of aligners required varies with each individual case, but 20-29 sets per arch is typical.

What are some considerations when wearing Invisalign^® aligners?

The aligners should be worn constantly, except when eating and drinking.  It is important to remove the trays when consuming food or drink because food can become trapped between the tray and the teeth, causing tooth decay.

Usually, new trays are necessary every two weeks and progress between appointments can usually be seen with the naked eye.
