Invisalign®: the simplicity of transparent orthodontic aligners


Digital radiographs, photographs and digital impressions of your teeth using the iTero® Element intraoral scanner will be taken at our office and sent to Invisalign®. Using 3D computer imaging technology, a digital model of your teeth will be generated.


Dr. Lavoie will prescribe a detailed treatment plan according to your specific needs and Invisalign® will follow those recommendations to fabricate a series of customized aligners. Each aligner will gradually guide your teeth to the position specified by Dr. Lavoie in order to correct your smile.


Each aligner will be worn for one week before being replaced by the following aligner. This is how your teeth will gently and progressively move towards their final straight position.


After the conclusion of your treatment, clear retention devices will be provided to protect your treatment and follow-up appointments will be necessary to ensure the harmony of your new smile. You can now smile and expose these beautiful straight teeth.

The length of the treatment will be determined by the severity of the case and by the number of aligners necessary to straighten your teeth. Often, treatment time will be similar or even shorter than with traditional braces. We will monitor your progress approximately every eight to ten weeks.


The cost of Invisalign® is similar to the cost of conventional braces. Since treatment is different for every patient, the cost will be determined by Dr. Lavoie at your initial consultation. We will also give you information about the interest-free payment plans offered.
