A method of determining an optimal switchover moment for a hybrid orthodontic treatment of teeth. Creation of a digital three-dimensional model of at least part of a dental arch. Deformation of the initial reference model until the tooth models are in a target position. Acquisition of at least one two-dimensional image of the teeth. Deformation of the initial reference model until the at least one updated image corresponds to the initial reference model. Determination, from the updated reference model and from said target reference model, of a plurality of remaining-treatments for moving the teeth from their position represented in the updated reference model into their position represented in the target reference model. Determination of a profile including at least one value for an evaluation parameter. Evaluation of each profile by an evaluation rule. Determination the profile of which is optimal for replacing an orthodontic appliance with an aligner.

A method of increasing movement of a tooth in a jaw having at least one tooth with an orthodontic brace thereon includes: (1) holding a handle of a device, the device having an elongate member extending from the handle and a screw tip at a distal end of the elongate member; (2) moving a sleeve along the elongate member to set a length of exposed screw tip; (3) locking the sleeve in place relative to the screw tip; (4) drilling a hole with the screw tip through a cortical bone of a jaw to increase movement of the tooth; and (5) stopping the drilling when the length of exposed screw tip has penetrated the jaw.

A dental device comprising one or more elongate elements such as wires arranged to contact and exert pressure on one or more teeth, and a reel, which reel is arranged to move the elongate element.

A method or apparatus for controlling movement of one or more teeth comprising a device and a software application operated remotely.

Smile treatment planning systems and methods are described herein. One method for adjusting an image of a smile may generally comprise receiving a three-dimensional (3D) digital model of a dental arch of a patient, receiving a digital facial image of the patient which includes an image of one or more teeth of the patient when smiling, registering the 3D digital model to the one or more teeth of the patient from the digital facial image, correcting the 3D digital model for scale and distortion to create a corrected 3D digital model, and overlaying the corrected 3D digital model onto the digital facial image.

Colored dental floss and a method for using colored dental floss. The colored dental floss includes an elongated filament having a plurality of segments, wherein each segment is a distinct color. The elongated filament is disposed within an interior volume of a container. The container includes an aperture for the elongated filament to pass therethrough. The method of using colored dental floss includes the steps of preparing a lingual side of a plurality of teeth for application of a bonding agent, applying the bonding agent to the lingual side, threading the elongated filament between a desired number of adjacent teeth in sections such that the elongated filament forms a plurality of loops on the lingual side, placing a wire through the plurality of loops, tensioning the elongated filament, applying the bonding agent to a contact point between the lingual side and the wire, curing the bonding agent, and removing the elongated filament.

An orthodontic appliance can include an archwire, ties, and multiple orthodontic brackets. The archwire can include multiple male fasteners and interproximal loops. Each male fastener may be inserted into an orthodontic bracket and tied into place. The male fastener may not be able to slide relative to the orthodontic bracket after it is tied to the orthodontic bracket.

A teeth adjustment arrangement includes a plurality of end retainers adapted for affixing to abutting teeth respectively; and a space expansion unit coupled between the end retainers to create an opposed expansion force against the end retainers for enlarging a corrective space between the abutting teeth corresponding to an associated tooth therebetween. Therefore, the associated tooth is adapted to concurrently move within the corrective space and align with the abutting teeth at the same time.
