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.

In some embodiments, systems, apparatuses, and methods are provided herein useful to orthodontic systems. In some embodiments, an orthodontic system comprises a carrier structure comprising a base, a plurality of groups of support structures, a plurality of orthodontic appliances associated with one of the plurality of groups of support structures, and at least one rail extending from the base, and an assembly structure comprising a body, a plurality of complementary pieces associated with one of the plurality of orthodontic appliances, at least one channel configured to interface with the at least one rail to allow the assembly structure to be moved from a first position to a second position with respect to the carrier structure, wherein movement of the assembly structure with respect to the carrier structure causes the plurality of complementary pieces to mate with the plurality of orthodontic appliances.

The present invention relates to an orthodontic height positioning gauge having bracket tabs to place a bracket, and lateral tabs configured to be placed along the occlusal surface of a lateral tooth. In such a position, the handle extends between the lateral jaw and the cheek, and the bracket located by the bracket tabs can be placed on the buccal surface of the tooth without hindrance due to the cheek.

An orthodontic appliance may include an outer shell having a plurality of cavities shaped to receive the patient's teeth and generate one or more of a force or a torque in response to the appliance being worn on the patient's teeth. The orthodontic appliance may also include an inner structure having a stiffness different than a stiffness of the outer shell. The inner structure can be positioned on an inner surface of the outer shell in order to distribute the one or more of a force or a torque to at least one tooth received within the plurality of cavities.
