Invisalign, the company, is so high tech it really is amazing to watch how they operate. They very rarely get it wrong. Their requirements for each case are photos, upper and lower impressions and a bite registration. In return, Invisalign, the company, returns with a CliniCheck, which is a computerized movie of the way they see the teeth should move with a specific set of aligners. Once the back and forth between doctor and Invisalign takes place and the CliniCheck is approved, Invisalign sends the complete set of aligners. Invisalign is amazing in its simplicity and complexity. It’s great to see the teeth move in the programmed sequence.
