In 1999, it was Align Technology that brought Invisalign to the world of orthodontics. This method uses plastic appliances to move teeth, slowly but surely, into the required position. Clear plastic makes these appliances look good and feel more comfortable than the usual metal braces. Since they are not fixed, they can be easily taken out for eating and cleaning their teeth. For this reason patients have a peace of mind with regard to dental hygiene during the treatment. The most comprehensive information on braces can be found on that website.
A computer comes in handy for a 3D simulation of the current state of the teeth and the way they are intended to be after the Invisalign procedure. Once the before and after states are decided upon, appliances are created to take the patient through 20 to 30 stages of the process. Each appliance is used for approximately two weeks and then the next one is used. The consecutive set of appliances is given to the patients only after their teeth have been checked for developments, which happens every four to six weeks.
