iTero® Scanner


Our practice is unique for having the iTero digital scanner impression system. The iTero scanner takes 3-D digital impressions of your teeth and bite. This system is more comfortable, more accurate, and more efficient than taking traditional, messy, uncomfortable impressions which can gag you. Learn More



For patients seeking Invisalign treatment, the iTero scanner instantly and exclusively sends the digital impressions to Invisalign. Right after scanning, the iTero software shows the Invisalign Outcome Simulator, which helps patients visualize how their teeth may look at the end of treatment. Learn More
