Abstract: Methods of making a removable dental positioning appliance include forming a sheet of transparent crystalline polymeric material into a shell having cavities shaped to receive and reposition teeth from a first orientation to a successive orientation. The polymeric material may then be annealed at a temperature above its glass transition temperature or cured if a curable material to enhance characteristics of the polymeric material. The polymeric material may be coated with a second transparent material.

Abstract: The polymeric shell of a removable dental positioning appliance is formed from transparent polymeric materials having a tensile strength at yield of greater than 6,000 pounds per square inch (psi), an elongation at yield of greater than 4%, an elongation at break of greater than 80%, a tensile modulus greater than 200,000 psi, a flexural modulus greater than 200,000 psi, stress relaxation over time of not more than 50%, and a transmissivity of light between 400 nm and 800 nm greater than 75%.

Abstract: A method and system for improving dental esthetics. Specifically, the method includes providing a polymeric shell dental appliance of a type that is removably placeable over a patient's dentition. The polymeric shell dental appliance comprises a concave trough which conforms to at least one tooth when placed over the patient's dentition. In addition, the method includes changing a visual appearance of a segment of the polymeric shell dental appliance. The visual appearance of the segment is changed by applying a thin film to a surface of the segment. In particular, the segment is disposed in a location corresponding to a portion of the patient's dentition that is to be esthetically improved.

Abstract: A method to create a digital model of a patient's teeth includes taking an impression of the patient's teeth using a radiopaque dental tray; scanning the impression and the dental tray using a dental tray containing a radiopaque agent; scanning the impression and the dental tray using a radiographic source; and generating the digital model with scanned data.
