    摘要： The present invention provides multi-layer adhesives and methods that are useful for bonding orthodontic appliances to a tooth structure. The multi-layer adhesives can be precoated on an orthodontic appliance, or alternatively, they can be provided on an adhesive delivery system for transfer to an orthodontic appliance. The multi-layer adhesives and methods preferably provide a useful balance of properties for bonding orthodontic appliances to the tooth structure.

    摘要： A release substrate is releasably placed across a layer of adhesive that has been coated onto the base of an orthodontic appliance such as an orthodontic bracket. The release substrate enhances separation from the adhesive coated on the appliance such that the shape of the adhesive is essentially undisturbed and preferably substantially all of the adhesive remains on the base of the appliance when the substrate is detached from the adhesive. The release substrate is particularly suitable for use with adhesives that have a relatively low viscosity, adhesives that are more tacky and/or adhesives that have less cohesive strength than adhesives conventionally used with precoated orthodontic appliances.

    摘要： An orthodontic separator, dimensioned such that it can be inserted between adjacent teeth. The separator is characterized in that it exhibits an increase in compressive force after insertion between adjacent teeth in the oral environment. The separator, after insertion, exerts sufficient force on the adjacent teeth to push the teeth apart.

    摘要： A computer implemented method of orthodontic appliance selection includes providing data representative of one or more teeth of a patient and providing data representative of a set of orthodontic appliances. Each orthodontic appliance of the set of orthodontic appliances has an appliance parameter that varies from the other orthodontic appliances of the set. At least one geometrical parameter of the one or more teeth of the patient is determined using the data representative thereof. The geometrical parameter is compared to the data representative of the set of orthodontic appliances and one orthodontic appliance of the set is selected based on the comparison. The set of orthodontic appliances may be a set of orthodontic bands with each band of the set having a different size. Further, such bands may be precoated with an adhesive material. A computer readable medium tangibly embodying a program executable for use in selection of orthodontic appliances, a system for use in orthodontia using such selection, and a method of fitting an orthodontic band to a patient are also provided. Further, an article including a container and a set of precoated bands received therein is provided.

    摘要： An orthodontic archwire with a certain cross-sectional construction has a stiffness that is less than conventional archwires having identical overall dimensions. The archwire has four corner edge portions that provide control over torquing movements and uprighting movements of the associated teeth as may be needed during the course of orthodontic treatment. The archwire is particularly useful during the early stages of orthodontic treatment when an archwire of reduced stiffness is desired and yet control over torquing and uprighting movements of the associated teeth is sought. Optionally, the archwire includes an aesthetic coating with certain characteristics that enable the majority of the coating to remain intact and provide an improved overall appearance even if certain regions of the coating are damaged and removed.

    摘要： An orthodontic bracket, such as a bracket made of ceramic material, is provided with a liner that enhances sliding mechanics between the bracket and an archwire. A portion of the liner projects beyond the bracket body and optionally includes an occlusal, gingival or lingual section that extends over a mesial or distal side of the bracket body. A bottom surface of the liner is located a distance from a bottom wall of a channel receiving the liner, and the distance optionally varies along the length of the archwire slot in order to urge the attached tooth to rotate as needed about its long axis. The liner is bonded to the bracket body in such a manner that the bracket body is thereafter held by the liner in compression.
