A custom tool for bonding orthodontic appliances in a mouth of a patient, the custom tool comprising: a facial body for a patient-specific, customized fit with the facial side of a plurality of teeth of the patient, a lingual body for a patient-specific, customized fit with the lingual side of the plurality of the teeth of the patient, wherein the lingual body. wherein the facial body and lingual body are configured to combine with the teeth of the patient to position orthodontic appliances on the plurality of teeth.

The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment formation structure. One dental attachment formation apparatus includes a body having a first surface shaped to conform to the contours of an exterior surface of a tooth and including a portion of the first surface shaped to accommodate an attachment that is to be attached to the exterior surface of the tooth and a light source attachment structure for attachment of a light source to the body.

The present disclosure describes articles, systems, and techniques including an additive manufactured orthodontic attachment including a body defining a retaining member configured to retain the article in a recess defined by a shell of a transfer tray; a coupling portion configured to engage a tool for insertion of the attachment into the recess of the transfer tray; and a bonding surface configured to bond the attachment to a portion of an outer surface of a tooth of a patient.

The present invention provides an improved orthodontic bracket with integrated piezosensor chip determining even the slightest change in initial installation setup of orthodontic bracket system and further notifying the subscriber electronically comprising of orthodontic bracket, for holding the tooth; at least one wire, for connecting the orthodontic brackets; and at least one sensor chip placed on the bracket and/or on the wire, wherein, at least one pulse oximeter is installed at the periphery of the bracket base to ensure force applied are within biological limits; the invention provides a detachable wireless frequency transmitter to be placed on the bracket of tie-wing to permit clinical recycling of the bracket; and optionally allowing a handheld laser scanner/photospectrometer to measure the frictional coefficient between the archwire and bracket to determine exact amount of force required for tooth retraction; to determine the bonding technique for detecting voids in adhesive; and to determine the distance between forces applied and center of mass of the tooth.

A self-ligating bracket include a bracket body with an arch wire slot. A mesial recess is located at a mesial side of the bracket body and extends into the bracket body from the arch wire slot. A distal recess is located at a distal side of the bracket body and extends into the bracket body from the arch wire slot. A central ridge defines a ridge surface separated from the lateral ledges respectively by mesial and distal walls. A clip includes a first arm and a second arm connected by a U-shaped portion. The first arm terminates in a mesial arm, a distal arm, and a middle arm. The clip is moveable between an open position in which the arch wire slot is accessible and a closed position in which the arch wire slot is occluded.

A butterfly attachment to guide a clear aligner to grip a tooth. The butterfly attachment is formed by two substantially quarter sphere units, wherein each unit has a convex surface and a concave surface. The two units are merged at their convex edge mid portions, such that the convex surfaces are continuous and forms a front face resembling a valley shape. The rear face of the butterfly attachment formed by the concave surfaces is also continuous and concave that corresponds to contours of the tooth.

A custom tool for bonding orthodontic appliances in a mouth of a patient, the custom tool comprising: a facial body for a patient-specific, customized fit with the facial side of a plurality of teeth of the patient, a lingual body for a patient-specific, customized fit with the lingual side of the plurality of the teeth of the patient, wherein the lingual body. wherein the facial body and lingual body are configured to combine with the teeth of the patient to position orthodontic appliances on the plurality of teeth.

A method for dental treatment may include receiving a plurality of images of a patient's dentition, identifying, from the plurality of images, individual teeth of the patient's dentition, detecting, from the plurality of images, one or more attachments on the patient's dentition, assigning, based on each of the plurality of images, each of the one or more attachments to one of the individual teeth in each image, and combining the assignments of each of the plurality of images for attachment detection results.

Systems for fabricating dental appliances are provided. In some embodiments, a system comprising one or more processors, and a memory operably coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the system to determine an appliance geometry for a dental appliance including a shell configured to move the patient's teeth from an initial arrangement toward a target arrangement. The appliance geometry can include a first power arm having a first connection point for connecting to the shell, a second power arm having a second connection point for connecting to the shell or to a tooth, an elongate connecting structure coupled to the first and second power arms, and an elongate counter-force connector coupled to the first power arm and extending toward the second power arm.

Methods and systems for digitally designing a plurality of aligners are provided. In some embodiments, a method includes receiving an intraoral scan of the patient's teeth, and generating 3D dental model of the patient's teeth using the intraoral scan. The method can include identifying a movement path to move the patient's teeth from an initial arrangement toward a target arrangement through a plurality of intermediate arrangements in accordance with a treatment plan. The method can also include identifying one or more appliance features of at least one aligner, the one or more appliance features including one or more feature regions having one or more feature thicknesses. The method can further include instructing an additive manufacturing machine to directly fabricate the at least one aligner in a layer-by-layer fashion.
