Abstract: Methods of forming dental tooth positioning appliances. Methods may include identifying a portion of a first digital model corresponding to a portion of the dentition for chemical treatment. Methods may also include forming a second digital model with a scaled up cavity by scaling up a size of a tooth of the first digital model. Methods may further include forming a polymeric shell including a scaled up cavity having dimensions that are proportional to a corresponding surface of the second digital model. The polymeric shell may further include one or more spacers that protrude from an inner surface of the scaled up cavity. The spacer(s) may be arranged to maintain a uniform space between the polymeric shell and the portion of the dentition identified for chemical treatment, and for holding a chemical for treating the identified portion of the dentition.

Abstract: Methods of attaching a wire to a dentition. The methods may include placing a shell on the dentition, where first cavity of the shell includes an attachment material reservoir for receiving an attachment material, and second cavity of the shell includes a wire attachment member having a slot for receiving the wire. The methods may also include placing the wire through the attachment material reservoir and through the slot of the wire attachment member to hold the wire in position with respect to a tooth within the first cavity. The methods may further include placing the attachment material within the attachment material reservoir to bond the attachment material and the wire to the tooth. Once the shell and the wire attachment member are removed from the dentition, the wire remains attached to the tooth via the attachment material.

Abstract: Methods for treating a patient are provided. These methods may include receiving scan data of a patient's teeth, forming a modified image of the teeth to simulate a dental treatment, combining the modified image of the teeth with an image of the patient's face to show an image of the patient's smile as it would appear according to the dental treatment, displaying the modified image to the patient, and treating the patient according to the simulated dental treatment.

Abstract: Various methods and systems for designing a restored smile are provided. One method includes receiving scan data of a patient's teeth, developing a digital model of the patient's teeth via a computing device, where the model represents the patient's teeth based upon the scan data, creating a dental treatment plan to restore one or more teeth from an initial condition to a successive condition, and wherein a final condition of the one or more is based on the one or more teeth having at least one planned additional restorative tooth structure provided therewith.

Abstract: Embodiments include dental appliances, dental appliance systems, and methods of making and using such appliances. In one embodiment, a dental appliance includes a shell having a number of cavities to receive one or more teeth, each cavity having an inner surface. Fewer than all cavities are scaled-up in size by a first selected percentage over one or more dimensions of a corresponding tooth surface to provide a uniform space between the cavity inner surface and the corresponding tooth surface.
