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.

Très bon service! J’y suis allée pour faire recoller mon fil lingual, mon orthodontiste étant retraité. Les filles à la réception étaient vraiment gentilles et l’hygiéniste Geneviève très attentionnée. J’ai trouvé Dr Lavoie très professionnel.
