The invention relates to a method for manufacturing at least one bone anchor and a corresponding drilling template, wherein the bone anchor has an anchor plate which is to be fixed to the surface of a bone by means of one or several screws having a screw head. The anchor plate thus has a bone side which is to connect to the surface of the bone and a free side which is opposite to said bone side. Further, the invention concerns a method for manufacturing a drilling template making it possible to make bore holes in the bone at predetermined positions and to screw the bone anchor to said bone according to predetermined orientations.

A tool and method for seating an orthodontic aligner, unseating the aligner, or both. In one aspect, the tool comprises a handle portion and seating portion. The seating portion is connected to the handle portion. The seating portion comprises a rippled structure having the shape of a series of waves, the waves having a direction of propagation directed away from the handle portion. In a second aspect, a handle portion of the tool comprises a hook adjacent to a recess in the handle portion, the hook being configured to unseat an aligner. In a third aspect, the method comprises seating an aligner by holding a handle portion of the tool, positioning the seating portion between sets of teeth and repeatedly biting the seating portion. In a fourth aspect, the method comprises unseating an aligner by holding the rippled seating portion and using the hook to apply force to the aligner.

The present invention relates to orthodontic brackets designed for use with the deciduous teeth and method for its use. The brackets provide one or more debonding tabs which reduces the potential for damage to the deciduous tooth due to the application of excessive force during the debonding process. The small size of the brackets allow the brackets to fit available crown space on the deciduous teeth. Further the brackets are shaped to minimize mechanical forces applied to the deciduous teeth when engaged with an archwire. The bracket bases are shaped to conform to the morphology of the deciduous tooth crown surface thereby providing an optimal adhesive interface with the deciduous tooth. The deciduous brackets provide proper adhesion to avoid unwanted detachment of the brackets which often occurs when the use of permanent brackets is attempted on the deciduous teeth.

Systems and methods of remote orthodontic treatment include receiving a plurality of images from a customer where the plurality of images represent teeth of the customer, receiving a first approval from a staff computing device where the first approval is indicative of a staff user approving the plurality of images for assessment by a dental professional, receiving a second approval from a provider computing device where the second approval is indicative of the provider approving a fitness of the customer for treatment, generating, in response to receiving the second approval, a treatment plan including a series of steps to reposition at least one tooth of the teeth of the customer, and manufacturing one or more aligners based at least in part on the treatment plan where the aligners are specific to the customer and are configured to reposition the at least one tooth of the teeth of the customer.

Systems and methods for determining an updated target orthodontic force are provided. A method includes receiving feedback data obtained during use of an orthodontic appliance configured to apply a target orthodontic force to a tooth of a patient. The feedback data includes one or both of patient feedback data points and treatment feedback data points. A value of the target orthodontic force having been determined by inputting periodontal ligament (PDL) behavior data into an algorithm. The method includes updating the algorithm using the feedback data and using the updated algorithm to determine an updated value corresponding to an updated target orthodontic force for use in reconfiguring or replacing the orthodontic appliance so as to apply the updated target orthodontic force.
