If you are having Invisalign the colour photographs of your profile, smile and mouth as well as study models are sent to Invisalign. These are matched to John’s prescription for you and a virtual model of your mouth and the projected results are presented in a ClinCheck video. We then invite you back to discuss and review the video so that you have a clear idea of what your teeth will look like at the end of treatment. John will discuss any changes etc. to you. This is the point at which we can definitively tell you how long the first stage of treatment is going to last. We then order the aligners.
