摘要： The appliances and methods provide a tab on a “U”-shaped clip having a labial (i.e. toward the patient's lips or cheek) section and a lingual (i.e. toward the patient's tongue) section. The tab is located in a position that facilitates access by a practitioner and also reduces the moment applied to the clip when the clips is opened and closed. Advantageously, the tab can be positioned to account for the varying degree of resistance encountered by different sections of the clip and minimize the likelihood of either distorting the clip or torquing the appliance. The tab can be positioned coplanar with the sliding mechanism. Advantageously, these appliances can provide improved ease of use, reduced clip distortion over time, and greater patient comfort.

摘要： A quantity of a photocurable composition, such as an orthodontic adhesive containing a photoinitiator, is placed between the base of an orthodontic appliance and a replica of a patient's tooth structure. The replica is made using a material that transmits actinic radiation. As the appliance is pressed into firm contact with the replica tooth structure, an outer surface of the photocurable composition assumes the configuration of the underlying portion of the replica tooth structure. Actinic radiation is then directed to the photocurable composition, and at least part of the actinic radiation is directed through the replica tooth model in order to harden the photocurable composition. The hardened composition provides a contoured bonding surface having a shape that matches corresponding regions of the patient's tooth structure. Methods are also disclosed for making an orthodontic indirect bonding transfer apparatus for use with appliances having a contoured bonding surface.

摘要： Orthodontic adhesive is cooled below ambient temperature in order to facilitate applying the adhesive to the base of an orthodontic appliance. The adhesive is placed on a carrier and formed into a certain shape on the carrier, and then released from the carrier while cool. In one embodiment, a quantity of adhesive is placed on the base of the appliance, and the appliance is then moved to a cut-off die while the adhesive remains cool and relatively brittle; next, a stream of pressurized air fractures and removes excess adhesive from the appliance base.

摘要： A virtual model of a dental patient's dentition is provided by obtaining a digital data file of the patient's teeth and orthodontic appliances connected to the teeth, and then combining data from the data file with other data that represents surfaces of the teeth underlying the appliances. The virtual model is useful in preparing a physical model of the patient's current dentition that can be used, for example, to make a dental retainer. Advantageously, the retainer can be fabricated before the orthodontic appliances are disconnected from the patient's teeth and ready for use as soon as the patient's teeth have reached their desired positions in the oral cavity.

摘要： A digital orthodontic treatment planning system provides a practitioner with digital representations of at least a part of a tooth of a patient and at least part of a coupling matrix within a three-dimensional environment. By interacting with the system, orthodontic practitioners are able to visualize a coupling matrix that results from a specific orthodontic appliance position relative to a tooth of the patient's dental arch. The digital representation of the coupling matrix represents a substance, such as a cured adhesive, that connects an orthodontic appliance to a tooth of a patient. The system determines a thickness of at least a portion of the coupling matrix. In one embodiment, the system indicates the total thickness via a thickness map, such as a color-coded thickness map. In another embodiment, the system indicates a deviation from a baseline thickness via a thickness map.

摘要： The relative orientation of an orthodontic appliance and a tooth is selected by providing a first relative orientation between the appliance and the tooth, and defining a first set of hypothetical reference lines or rays between the base of the appliance and the tooth in virtual three-dimensional space. The distance along each ray is then determined. Next, the relative orientation of the appliance and the tooth is changed to a second orientation. A second set of rays is defined between the appliance and the tooth, and the distance along each ray is determined. A mathematical computation is then carried out on the determined distances in order to help determine whether the first orientation or the second orientation provides a better fit between the base of the appliance and the tooth surface.

摘要： An orthodontic appliance includes a base with an outer surface, as well as at least one passageway extending through the base. An element is received in each passageway and is made of a material that transmits actinic radiation. The element serves as a window to facilitate the curing of light-curable orthodontic adhesive beneath the appliance base, while simultaneously preventing movement of the adhesive through the passageway. Optionally, one or more optical fibers are provided to facilitate curing of the adhesive.
