摘要:
An orthodontic device for displacing a tooth and/or a group of teeth of a patient, which directly adjoin the tooth along a mandibular arch, in particular in the lower jaw in the area of the molars, the device comprising: a rigid, dimensionally stable connection between the tooth to be displaced and an attachment point for the device which fixed to the jaw and substantially does not change during the treatment of the patient, a regulating device for changing the length of the rigid connection in direct vicinity of the tooth to be displaced. A torsion-proof attachment of the device in the jaw bone may be provided. Alternatively, a point of support is provided on one tooth.

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.

Orthodontic bracket assemblies with torque-adjusting drums. The drum defines at least a majority of the archwire slot of the corresponding bracket assembly, and the drum may be selectively rotated about its longitudinal axis to adjust the prescriptive force that is applied to a patient's tooth during orthodontic use of the bracket assembly. The bracket assembly includes a positioning assembly that selectively retains the drum in a selected orientation relative to the base of the bracket assembly, thereby defining a prescription to be imparted by the bracket assembly to a patient's tooth. In some embodiments, the bracket assembly includes a biasing mechanism that selectively urges the positioning assembly to a position in which the drum is, or is not, retained in a selected position. In some embodiments, the bracket includes a release mechanism that selectively disengages the positioning assembly to permit adjustment of the drum.

The present invention relates to an orthodontic gripping device having a body made of a superelastic metal alloy, cold worked titanium beta III, or solution heat treated and aged titanium beta III. The body has first and second, spaced apart arm portions connected to each other. Each arm portion includes a jaw portion having an inner, arch wire-gripping, surface. The inner gripping surfaces are disposed opposite one another in spaced relation with a station defined therebetween for receiving the arch wire. At least a portion of the station is sized smaller than the arch wire. The arm portions are resiliently deflectable outwardly away from each other to admit the arch wire into the station. Once seated in the station, the arch wire is tightly held by inner gripping surfaces so as to resist displacement of the gripping device relative to the arch wire.

A computer-aided method for designing a surgical template for dental and/or orthodontic implants comprises acquiring a first 2D or 3D image of the oral cavity and of the overlying anatomical structures of a patient, processing the first image for defining one or more second 2D images showing corresponding views or sections of the oral cavity, realizing a digital model of the upper dental arch and of the palate of the patient to identify one or more suitable sites for inserting a corresponding implant, selecting one or more slices of the digital model at one or more sagittal or parasagittal planes passing through respective insertion sites, overlapping the slices with corresponding second 2D images for generating a third 2D image, providing a digital library of implants for the selection thereof and for their virtual positioning into the third image in order to allow the adjustment of the inclination and/or the deepness of insertion. A surgical template for dental and/or orthodontic implants suitable to be manufactured with the above method.
摘要:
An orthodontic appliance includes features for reducing friction between an interior of an archwire slot portion of the appliance and an archwire to be placed within the archwire slot. Other embodiments include a rounded exterior occlusal surface. Embodiments further include one or more receptacles for receiving an installation tool.
摘要:
The invention relates to an orthodontic tool for the placement, positioning and attaching of brackets using a direct or indirect method, said tool comprising two parts: a body for manipulating the device (1) and a point (2). The shape of the body (1) is compatible with the hand and offers the user control and comfort when arranging the bracket (100) on the target—the target being the mesiodistal centre of the dental piece or tooth—at a predetermined height (202), resulting in precision and accuracy.
摘要:
Tool for actuating palatal expanders, comprising a body (1) with a grip portion (2) and, on the opposite side, a tip (3). The body (1) has, on at least one surface (10) thereof, display means adapted for displaying the number of uses.
摘要:
Devices, systems, and methods for adjusting a prescription of a plurality of orthodontic brackets are disclosed herein. The devices include an orthodontic prescription-defining device that includes a plurality of contacting structures and a plurality of prescription-defining engagement structures. The systems include the orthodontic prescription-defining device and a plurality of orthodontic brackets. The methods include unlocking each of a plurality of orthodontic brackets, operatively contacting a plurality of contacting structures of an orthodontic prescription-defining device with a plurality of intra-oral reference points, urging each of a plurality of archwire slots to a respective preselected orientation, and locking each of the plurality of orthodontic brackets in the preselected orientation.
摘要:
The present invention relates to an orthodontic force measuring device using a typodont and a load cell, and more particularly, to an orthodontic force measuring device using a typodont and a load cell, which connects an orthodontic application wire to a typodont, employs a load cell to measure an orthodontic force, reduces measurement error which may occur in a measurement method based on an image, precisely measures an orthodontic force, and measures an orthodontic force in a three-dimensional manner.
