In some embodiments, apparatuses and methods are provided herein useful to marking orthodontic devices. In some embodiments, a carrier for orthodontic appliances comprises a base that is additively manufactured and comprising a plurality of wells configured to house orthodontic appliances and a marking integral to the base, wherein the marking identifies one or more of the orthodontic appliances and locations for the orthodontic appliances. In some embodiments, an orthodontic appliances comprises a body including features and a bonding surface, wherein the orthodontic appliance is additively manufactured and includes a marking integral to the orthodontic appliance, wherein the marking is located on one or more of the body and the bonding surface.

A method of manufacturing customized ceramic labial/lingual orthodontic brackets by digital light processing, said method comprises measuring dentition data of a profile of teeth of a patient, wherein measuring dentition data is performed using a CT scanner or intra-oral scanner, based on the dentition data, creating a three dimensional computer-assisted design (3D CAD) model of the patient's teeth using reverse engineering, and saving the 3D CAD model on a computer, designing a 3D CAD bracket structure model for a single labial or lingual bracket structure, importing the 3D CAD bracket structure model into a Digital Light Processing (DLP) machine, directly producing the bracket by layer manufacturing.

Appliances for orthodontic treatment are provided. In some embodiments, an orthodontic appliance includes a shell having a plurality of teeth-receiving cavities shaped to reposition a patient’s teeth from a first arrangement toward a second arrangement. The shell can have a first elasticity. The appliance can include an attachment-receiving well formed in the shell. The attachment-receiving well can be configured to engage an attachment coupled to a tooth of the patient. The appliance can further include at least one tactile object coupled to the attachment-receiving well. The at least one tactile object can include an elongate body that extends toward the attachment when the shell is worn on the patient’s teeth. The at least one tactile object can have a second elasticity greater than the first elasticity.

Method and system for establishing an initial position of a tooth, determining a target position of the tooth in a treatment plan, calculating a movement vector associated with the tooth movement from the initial position to the target position, determining a plurality of components corresponding to the movement vector, and determining a corresponding one or more positions of a respective one or more attachment devices relative to a surface plane of the tooth such that the one or more attachment devices engages with a dental appliance are provided.

Systems, methods, and devices for improved orthodontic treatment of a patient's teeth are provided herein. A method may include determining a movement path to move one or more teeth from an initial arrangement to a target arrangement, determining an appliance geometry for an orthodontic appliance comprising a shell and one or more integrally formed components, wherein the shell comprises a plurality of teeth receiving cavities shaped to move the one or more teeth from the initial arrangement to the target arrangement, and generating instructions for direct fabrication of the orthodontic appliance, wherein the instructions are configured to cause direct fabrication of the shell using a first material and direct fabrication of the one or more integrally formed components using a second, different material.

Systems and methods for fabricating indirect bonding trays are disclosed. Physical models of a patient's teeth can be created with non-functional placeholder brackets, impressions of which can be transferred to indirect bonding trays. This can create wells in which functional brackets can be placed into, reducing errors created from transferring functional brackets from the physical model onto the indirect bonding trays.

An orthodontic bracket with an adjustable hook designed to facilitate bending. The orthodontic bracket includes a bracket body mountable to a tooth and an adjustable hook extending from the bracket body, the adjustable hook comprising a stem base structure a bend region extending from the stem base structure, a neck region extending from the bend region, and a head extending from the neck region. In some embodiments, the adjustable hook has a length, L.sub.1, measured from a bottom portion of the stem base structure to the head, and a length, L.sub.2, measured from a bottom portion of the neck region of the hook stem to a free end of the head, wherein L.sub.2 is greater than or equal to 60% of L.sub.1.
