Modern computer technology has provided dentists and patients with a new technique for moving teeth. It does away (in most cases) with the old metal bracketing that most patients, especially adults, disliked. A software program has been developed that analyzes an impression made of your teeth by the dentist. The computer then directs a machine that makes thin plastic molds that are each a little different and make your teeth move into the final corrected position. This method is not suitable for all orthodontic situations. Adults with crowding or mis aligned teeth are the best candidates.
