Each of the plurality of screws has a screw part that is embedded in the bone and a polygonal-columnar head part that is exposed inside the oral cavity. The base member has at least three engagement holes that are provided so as to be capable of engaging the polygonal-columnar head parts and such that the centers thereof are not on the same straight line.

Systems and methods for determining an orthodontic treatment plan

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.

A ligating clip for a self-ligating orthodontic bracket includes: a labial arm having a free end and a further end; a lingual arm having a free end and a further end; a connecting arm connected to the further ends of the labial arm and the lingual arm the labial arm, wherein the connecting arm and the lingual arm each have a distal side and a mesial side, the labial arm and the lingual arm extend generally in a gingival-occlusal direction and the connecting arm extends generally in a lingual-labial direction; and a locking element in form of a hook arranged at the free end of the lingual arm, wherein the hook protrudes in a lingual-labial direction. At least one cutout is arranged at the free end of the lingual arm, the at least one cutout being open at either the distal or the mesial side of the lingual arm.

Dental Bracket with Removable Bracket Covers
20220395356 · 2022-12-15 ·

A dental bracket can be used to generate a force profile corresponding to a target tooth movement (e.g., for moving and aligning the teeth of an orthodontic patient). The dental bracket includes a base and a cover. The base is configured to be attached to an anterior surface of a tooth, and the cover is removably attached to the base. The cover includes a slot configured to receive a wire. In some implementations, at least one of the size, shape, or orientation of the slot corresponds to a force profile corresponding to a target tooth movement. Example target tooth movements include a mesial root movement, a distal root movement, a mesial crown movement, a distal crown movement, an intrusion movement, an extrusion movement, a mesial crown rotation, a distal crown rotation, a buccal root movement, or a lingual root movement.

Simulated orthodontic treatment via augmented visualization in real-time

A system and method for simulating orthodontic treatment using augmented reality. An electronic image of a user's face is received from a digital camera, and a region of interest in the image is identified where the region includes the user's teeth. Virtual orthodontic appliances are placed on the user's teeth in the image, and the user's image with the virtual orthodontic appliances is displayed on an electronic display device. The method occurs in real-time to provide the user with the augmented image simulating treatment when or shortly after the image of the user is received. The system and method can display a 3D representation of the user's face augmented with the virtual appliances. The user's augmented image or 3D representation can also be supplemented for display with an image or model of the user's facial anatomy such as an x-ray or a cone beam computed tomography image.

Method and apparatus for restoring improper morphology of the alveolar bone
11510756 · 2022-11-29 · ·

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.

METHOD FOR MONITORING AN ORTHODONTIC TREATMENT

A method for monitoring the positioning of the teeth including production of a three-dimensional digital initial reference model of the arches of the patient and, for each tooth, definition, from the initial reference model, of a three-dimensional digital reference tooth model; acquisition of updated image of at least one two-dimensional image of the arches in actual acquisition conditions; analysis of each updated image and production, for each updated image, of an updated map; optionally, determination, for each updated image, of rough virtual acquisition conditions approximating the actual acquisition conditions; searching, for each updated image, for a final reference model corresponding to the positioning of the teeth during the acquisition of the updated image, for each tooth model, comparison of the positionings of the tooth model in the initial reference model and in the reference model obtained at the end of the preceding steps to determine the movement of the teeth

Orthodontic shape memory band
11484391 · 2022-11-01 · ·

A method for producing a shape memory band of an orthodontic appliance. The shape memory band is one piece, has a cross section that can vary according to the longitudinal position of said cross section, and includes a bonding zone configured so as to exhibit a shape substantially identical to that of a tooth. The method includes: determining an orthodontic treatment suitable for treating the teeth, determining a set of forces to be exerted locally on the teeth in order to obtain the orthodontic treatment and the shape of the surface of the teeth to which bonding zones of the shape memory band are to be bonded, and producing the shape memory band. The local cross section of the shape memory band is determined according to the forces and in such a way as to define bonding zones substantially identical to the surfaces of the teeth.
