8 results about "Arch form" patented technology

An orthodontic appliance comprises a combination of pre-made and custom elements to provide treatment versatility with minimized costs and time delays. The appliance comprises a pre-made arch member segment elastically deformed to removably attach to coupling units bonded to teeth. The appliance also comprises a connection module to further elastically deform the arch member segment to generate motive forces or to just connect separate arch member segments in variations. In another embodiment the appliance comprises pre-made connectors having one end attached to a tooth and another end elastically deformed to attach to an arch component. The attachment to teeth comprises coupling units bonded to teeth in variations. The arch components, coupling units, and connection modules may be custom made to match surfaces inside the mouth. Motive forces may be generated by the elastic deformation of the arch member segment, connectors, arch component, or connection module to align teeth.

The utility model discloses an inverted arch formwork anti -floating device, it includes inverted arch formwork block, extrusion board: the inverted arch formwork block sets up at the downside of extrusion board, the upside of extrusion board is fixedly connected with square block no.

An occlusal seating device for orthodontic aligners, the body of which consists of two semi-autonomous arches, namely an upper arch (1) and a lower arch (2), which have spine-like interdental projections (3). The arches are interconnected in the rear distal part through pillars (4) and in the front by a flexible fusion. On the body of the seating device or at the ends of the spine-like interdental projections (3) buffer pressure points (6) are located for the application of a seating stick or an extraoral vibration source. Between the upper arch (1) and the lower arch (2) inter-arch vestibular connections (7) are located, the course of which is vestibularly convex. The body of the occlusal seating device has a shape complementary to the occlusal part of the upper and lower teeth of the patient with an invisible orthodontic aligner fitted.

An archform configured to move a patient's teeth using non-sliding mechanics. The archform can include a loop between two bracket connectors that spans a blocked-out tooth between two teeth. One or more of the bracket connectors can include a reinforced shoulder to provides increased structural integrity to the connection between the bracket connector and the loop. The archform can include a second loop between the two connectors that is gingivally or occlusally positioned relative to other loop.

The invention relates to an invisible correction device for bidirectional jaw regulation and control. Comprising an upper jaw appliance body and a lower jaw appliance body, the upper jaw appliance body comprises a first body part, a first protruding part and an arch expanding part which are integrally formed, and a first guiding inclined face is arranged behind the first protruding part; the lower jaw appliance comprises a second body part and a second convex part which are integrally formed, and a second guide inclined surface is arranged in front of the second convex part; the first guide inclined surface and the second guide inclined surface are attached to each other when the user occludes the jaw, and the first lug boss and the second lug boss jointly guide the functional retreat of the lower jaw; the arch expanding part is provided with an arch structure attached to the palate of a user, the upper surface of the arch structure abuts against the palate of the user and acts on dental crowns on the two sides in the transverse direction, expanding force is provided for the left side and the right side at the same time, and therefore the maxillary dental arch is expanded. Through the integrated and complete-cycle correction system, the limitations of overlong treatment course, poor correction experience, jaw bone and dentition control separation and the like in the existing two-stage correction mode are overcome.

The utility model discloses a conversion fixture for false tooth processing, which belongs to the technical field of dental medical instruments and comprises an arch-shaped block fixedly connected with a clamping groove of the fixture, one end, far away from the clamping groove, of the arch-shaped block is fixedly connected with a positioning groove, and the positioning groove is fixedly connected with a processing material; the arch-shaped block comprises an arc-shaped end and a straight end, the arc-shaped end is fixedly connected with the clamping groove, and the straight end is fixedly connected with the positioning groove; the arc-shaped end is fixedly connected with an angle positioning block, and the angle positioning block abuts against the edge of the clamping groove so as to limit the angle of the arc-shaped block. According to the utility model, the processing material and the clamp are connected through the arch-shaped block, so that the functionality and the stability of the clamp are improved, the utilization rate of the processing material is also improved, the production cost is reduced, and the processing efficiency and the processing precision are improved.
