Invisalign® gradually shifts teeth over a period of several months to two years, all designed through the use of computerized dentistry. After a thorough examination of your teeth and gums, an impression will be taken of your teeth and sent to the Invisalign® laboratory. The laboratory technicians will use advanced three-dimensional computer imaging to create a series of aligners based on this impression and the specifications provided by Dr. Salizzoni. Each custom-manufactured aligner in the series will move your teeth closer to their ideal position within your mouth. You will replace the aligner you are wearing with the next in the series roughly every two weeks.
