How it works is by using 3D scans of a person’s mouth cavity using facial scanning technology — a procedure which is already being used by many dentists — and matches it with scans of known sets of good teeth already used for the procedure. A live video of the patient’s teeth is taken and a virtual set of post-treatment teeth is then superimposed on that.
Using a ultra cool term like “Augmented Reality” makes this sound like it is more advanced than it really is. This is just an updated version of cosmetic imaging, which has been around for twenty years.
Having said that cosmetic imaging is a very powerful tool. I have had many patients choose to move forward with needed dental treatment as a result of seeing the results in a cosmetic simulation.
