§16§This "Invisalign" system offers adult patients full orthodontic treatment with an esthetic appliance. Through the use of computer assisted technology, Invisalign Technology can scan a patient's study models and provide a virtual treatment setup. This virtual treatment is a 3-dimensional view of tooth movements required to achieve the desired treatment result. These tooth movements occur in stages. A new clear plastic tray, called an aligner, is fabricated for each stage. By wearing these aligners in sequence, the patient can achieve the final treatment result. Orthodontic treatment with this appliance is a potentially useful alternative approach to fixed appliances for treatment of a variety of malocclusions in patients with fully erupted permanent teeth.
