Embodiment Construction

[0036] A system for moving teeth of a patient's dental arch from a first tooth arrangement to a second tooth arrangement comprises a plurality of resilient appliances that are used in sequence. In the embodiment illustrated in FIGS. 1-3, the appliances comprise trays, and an exemplary tray of the system is broadly designated by the numeral 10. In FIGS. 2 and 3, the tray 10 is shown in use, placed over an exemplary dental arch 12 of an orthodontic patient. The tray 10 is shown alone in FIG. 1.

[0037] The tray 10 includes a row of spaced apart couplings or receptacles 14 (see FIG. 3), each of which is adapted to connect to and receive a respective tooth 16 of the patient's dental arch. The receptacles 14 are spaced apart from each other along the length of the tray 10, although adjoining regions of adjacent receptacles 14 are in communication with each other.

[0038] Each of the receptacles 14 includes at least one wall section 18 that is constructed to urge the respective tooth toward...

Abstract

Systems for moving teeth of a patient's dental arch from a first tooth arrangement to a second tooth arrangement include a plurality of resilient appliances such as positioning trays or elongated arch members that are used in sequence. Each appliance of the systems includes a row of spaced apart couplings for connection to respective teeth of the dental arch. The appliances have certain geometric characteristics that match the geometric characteristics of other appliances of the system, and at least one appliance has a stiffness that is greater than the stiffness of at least one other appliance.

Description

RELATED APPLICATION DATA [0001] This application is a continuation of application Ser. No. 10 / 983,457, filed Nov. 8, 2004, (U.S. 2006 / 0099544-A1) now allowed.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to orthodontic treatment systems wherein resilient appliances are used in sequence to move the patient's teeth to desired orientations in the dental arch. [0004] 2. Description of the Related Art [0005] Orthodontic treatment involves movement of malpositioned teeth to improved orientations. Orthodontic treatment can greatly enhance the aesthetic appearance of the patient's teeth, especially in regions near the front of the oral cavity. Orthodontic treatment can also improve the patient's occlusion so that the teeth function better with each other during mastication. [0006] One type of orthodontic treatment is carried out by the use of elastomeric positioning appliances, also known as repositioning trays or alignment trays. These appliance...
