Abstract: Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems include the generation of an overcorrection in the tooth-receiving cavities of an appliance worn in the dentition. The overcorrection may provide an improved and more accurately applied force or moment applied to a tooth. The overcorrected force or moment can move a tooth closer to a desired position than if not overcorrected as sufficient force can still applied to the tooth as it gets closer to the desired position. The overcorrected force or moment may also better target the root of the tooth where the biological response to tooth movement occurs. The overcorrection may be calculated in various ways as described herein.

Abstract: This disclosure generally describes an extended buccal tube which is used in connection with braces for the teeth. The extended buccal tube accommodates an arch wire of a sufficient length to allow space to be created between one or more teeth while retaining the arch wire within a tube of the extended buccal tube. As space is created and the arch wire slides through the extended buccal tube, an overall length of the arch wire may be monitored through one or more windows in the extended buccal tube. Tooth pads on extended buccal tube may be rotatable by up to 20° in two axes for fitment purposes. When space has been created between the one or more teeth, extended buccal tube may be cut along scoring lines to separate teeth that were bonded together by the extended buccal tube.
