Treatment begins with the insertion

The first thing that a patient learns about Invisalign is that it is a method of straightening teeth, one at a time, with the aid of removable, plastic trays that fit over the patient’s teeth. After a number of visits to an orthodontist, Invisalign takes an impression of the patient’s teeth. These impressions are used to make a three-dimensional model of the patient’s mouth that Invisalign uses to determine exactly how much force needs to be applied invisalign dentist to each tooth during treatment. Treatment begins with the insertion of the aligner trays and continues as the patient wears the trays at home. As a result, the treatment period usually lasts about two years. During the course of treatment, patients should wear the aligners for a minimum of 20 hours each day and should brush and floss as usual. After treatment, each set of aligners is removed and replaced with another set of aligners that move the teeth progressively farther into the correct position. Invisalign has been designed to eliminate visible metal bands, brackets, and other appliances that are usually necessary in traditional methods of orthodontic treatment. In addition, it is less traumatic for patients than the traditional braces method and can be used on children.
