Systems for force measurement upon orthodontic appliances are described. Generally, a system for measuring a force or moment imparted by an orthodontic appliance may comprise a dentition mold having one or more target teeth each formed upon a fixture and which is movable independently of the dentition mold, a measurement sensor coupled to the fixture, and a processor in communication with the measurement sensor. An orthodontic appliance may be configured for placement upon the dentition mold where the orthodontic appliance imparts a force or moment upon the one or more target teeth such that the force or moment is transmitted to the measurement sensor via the fixture for measurement of the force or moment.

A method and a system for determining an orthodontic treatment plan including a tooth stripping step are provided. The method comprises: acquiring a 3D digital model of a first tooth and a second tooth of the subject, the second tooth being adjacent the first tooth; receiving a stripping request for stripping tooth material, from at least one of the first tooth along a first stripping plane and the second tooth along a second stripping plane; determining, along a surface of the first tooth, a first area of interest; determining, along the surface of the second tooth, a second area of interest; determining a distance between a first set of vertices associated with the first area of interest and a second set of vertices associated with the second area of interest; in response to the distance being greater than a predetermined distance threshold, denying, by the processor, the stripping request.

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.

An orthodontic appliance and associated systems and methods are disclosed herein. In some embodiments, the present technology includes a positioning member configured to position an orthodontic appliance during installation in the patient's mouth. The positioning member may comprise a first portion configured to be coupled to the patient's teeth and a second portion extending away from the first portion. The second portion may be configured to be detachably coupled to the orthodontic appliance. While the positioning member is coupled to the orthodontic appliance, the positioning member is configured to be positioned in the patient's mouth and coupled to the patient's teeth, thereby positioning the orthodontic appliance at a desired location adjacent a patient's oral anatomy.

A method for treating orthodontitis (i.e., gingivitis caused by malpositioned teeth). The process includes evaluating improper morphologies of alveolar bone in the horizontal dimension (i.e., orthodontosis) caused by displaced root(s) of a tooth, uprighting the root of the malpositioned tooth utilizing an orthodontic bracket system thereby causing the alveolar bone to be restored, which in-turn alleviates the orthodontitis. An orthodontic bracket is provided for use with an arch wire to apply corrective forces to a tooth. The bracket includes a vertical member having a slot formed therein for receiving the arch wire and a wide base horizontal member connected to the vertical member. The vertical member is positioned gingivally with respect to the horizontal member. The horizontal member includes opposing first and second ends that extend away from the vertical member and define a pair of spaced-apart wire engaging points engageable with the arch wire during treatment.

A novel orthodontic apparatus is disclosed. The novel apparatus can be referred as a rectangular-retained arch (RRA). Examples of RRA can be used for stabilizing a new configuration of teeth so that the teeth do not move to an incorrect position. An example of RRA can have a shape of arch that is made of a single piece of material. Some embodiments of RRA can have a plurality of holes along the RRA.
