As of March 2015, iTero scans have been used in more than 1.3 million iTero orthodontic scans, including more than 600,000 Invisalign® scans. Here at O’Neill Orthodontics we use the scanner to help deliver a dental impression without the “goop” or gagging associated with conventional impressions. This state-of-the-art technology allows Dr. O’Neill to take highly accurate digital, 3D images of your teeth, or a digital dental impression.
