Abstract
Abstract 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.
