The Inman aligner is a self contained brace that realigns the teeth in adults that have problem teeth, says a South east London dentist. The units are pre-prepared and changed every two weeks to make sure they keep working on the teeth. From digital photos an orthodontist and a computer programmer will feed the information into a program to get the pressure points and design, and then make a series of braces to do the job. One by-product is a 3D computer generated film that shows the entire procedure, so the patient and dentist can keep a track on progress. The patient has the braces changed every two weeks to keep up the pressure as part of the course; the unit is similar to a gum shield and contains all the springs and pressure wires to do the job. The brace can be taken out for eating and cleaning or just for a rest, unlike conventional braces. As long as they aren`t out for any longer than 4 hours per day, it is fine to pop them out and then back in. With all the bits hidden on the inside anyway, it looks just like a clear gum shield except for a thin bar across the front that holds it all together. It is great for moving front teeth, but doesn’t work too well on the back teeth, for that you`ll to use the Invisalign Brace which is so called because it is almost invisible by not having the thin bar running across it, although it works in the same way.
