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.

The present invention provides systems and methods of managing planning and delivery of an orthodontic treatment using planning tools, treatment guidelines, instructions and appointment planning tools customized to the individual patient being treated, as well as tools and methods for tracking delivery and patient progression through an orthodontic treatment plan.

Continuous adjustment appliances are provided that can store a large number of geometries that can be successively accessed throughout orthodontic treatment, with each geometry can correspond to an arrangement of the patient's teeth. An appliance according to the present disclosure can be stimulated to transition among the myriad geometries, which can include changes to the overall shape of the appliance as well as the position and geometry of the cavities corresponding to a patient's teeth. Methods of creating the continuous adjustment appliances and methods of treatment using the continuous adjustment appliances are also revealed.

A device includes an antenna, markers disposed inside the device and configured to be movable inside the device to measure positions of a first tooth and a second tooth among teeth in the oral cavity, a sensor module measuring positions of the markers, and at least one of a distance between a reference point set in the device and at least one of the first tooth and the second tooth and a distance between the first tooth and the second tooth based on the measured positions of the plurality of markers. The device further includes a communication module transmitting to an external device at least one of information about the measured distance between the reference point set in the device and the at least one of the first tooth and the second tooth and information about the measured distance between the first tooth and the second tooth through the antenna.

Systems and methods of generating an orthodontic model are disclosed. The method may include: generating an initial model of a patient dentition; generating a target model of the patient dentition; defining a plurality of caps and a plurality of links, wherein each link connects two of the plurality of caps; generating a relaxed model of a dental appliance from the plurality of caps and the plurality of links; generating a deformed model of a dental appliance from the plurality of caps and plurality of links; and determining a plurality of movements, wherein the plurality of moments transform the relaxed model to the deformed model and wherein the moments are configured to direct the patient dentition from the initial model to the target model.

In some embodiments, apparatuses and methods are provided herein useful to providing data files associated with orthodontic appliances. In some embodiments, a system for providing data files associated with orthodontic appliances comprises a database, wherein the database stores the data files associated with the orthodontic appliances and a control circuit, wherein the control circuit is communicatively coupled to the database, a user device, and a printer, wherein the control circuit is configured to receive, from the user device, an indication of a selected orthodontic device, retrieve, based on the indication of the selected orthodontic device from the database, one of the data files associated with the orthodontic appliances, wherein the one of the data files associated with the orthodontic appliances corresponds to the selected orthodontic appliance, and transmit, to the printer, the one of the data files associated with the orthodontic appliances.

In one aspect, the present application provides a computer-implemented method for generating a digital data set representing a target tooth arrangement, comprising: obtaining a first 3D digital model representing an initial tooth arrangement; extracting at least one feature from each tooth of the first 3D digital model; generating a feature vector based on the extracted features; and aligning the first 3D digital model using a Statistical Shape Model based on the feature vector to obtain a second 3D digital model representing a target tooth arrangement.
