An orthodontic appliance is provided and includes: a base member fixed to two or more screws implanted in a vicinity of median palatine suture of a palate bone; an arm-shaped arm member having a first connecting portion connected to the base member and a second connecting portion located in a vicinity of palatal side of a tooth; and a traction member that is made of an elastic wire material and pulls a tooth as the traction target. The traction member has a traction base portion, a traction fixation portion, and a traction force generation portion. The traction fixation portion has a bent portion in which the wire material extending along dentition is plastically deformed and bent toward a tooth root side. The bent portion is hooked on a protruding portion protruding to a palate side in a bracket.

An implant positioning device is fitted on to an orthodontic brace of a patient and used in between an X-ray projecting machine and an X-ray film. The implant positioning device includes a measuring standard member, that forms a detection region by means of a radiopaque material and has a positioning unit on one side of the detection region. The detection region is provided with at least one set of measuring scales. An encircled member is integrated with one side of the measuring standard member and forms an encircling main body that is connected to the orthodontic brace. A sleeved space is collectively formed by the encircling main body and the measuring standard member.

A retainerless orthodontic dental implant system for positioning the mandible forward relative to the maxilla and for facilitating optimal airflow during sleep and a method of using such a system.

A tooth moving device 1 according to the present invention comprises: a track part 6 extending from a mesial end 4 to a distal end 5 along a palate-side teeth alignment; a sliding part 7, slidably attached to the track part 6, and engaging with a holding member 51 attached to a maxillary posterior tooth; a lock part 8 fixed to the track part 6 close to the mesial end 4 relative to the sliding part 7; an elastic part 9 intervening between the lock part 8 and the sliding part 7 to bias the sliding part 7 toward the distal end; and anchoring part 2 and 3, anchored to an implanted member 53 implanted into a palate, and connected to the distal end 5.

Systems, methods, devices and apparatus for mandibular advancement or retraction via bone anchoring devices are described herein. In various aspects, an apparatus for treating a patient via mandibular advancement or retraction comprises a plurality of anchoring devices positioned in the patient's intraoral cavity. Each of the plurality of anchoring devices can be positioned in bone of the patient's upper jaw or bone of the patient's lower jaw. One or more connecting structures can be removably coupled to and extend between the plurality of anchoring devices in order to displace the lower jaw anteriorly or posteriorly relative to the upper jaw.

An implant plate device comprises a plate base body, further comprises at least one fixing recess, which is introduced in the plate base body and is configured for receiving a jawbone screw that is configured, for a fixation of the plate base body, to be screwed through the fixing recess into a bone, in particular a jawbone, and comprises at least one inner thread adjoining the fixing recess, wherein the implant plate device comprises at least one functional recess, introduced in the plate base body, for a coupling with an orthodontic treatment apparatus and/or with a drilling and/or insertion templet.

An orthodontic abutment that includes a base suitable for fixing the orthodontic abutment to an implant, a cap fixed to the base and a set of retention elements arranged along a side wall of the cap. The set of retention elements is suitable for receiving orthodontic elements and includes: a bracket with wings, a hook arranged under one of the wings of the bracket, a projection arranged on the cap oppositely to the bracket, a hollow tube formed inside the projection, a curved rod hook arranged on the projection below the hollow tube, and a button with an eyelet arranged above the hollow tube.

The invention concerns a set with a bone anchor (2) for an upper or lower jaw (1,17) and a corresponding drilling template (10) for making drill holes in the jaw (1,17), wherein the drilling template (10) contains an anchor plate (3′) of which the shape and dimensions are virtually the same as those of at least the bone side (8) of the bone anchor's (2) anchor plate (3), wherein the drilling template (10) has a connecting element (6′) which is rigidly connected to the anchor plate (3) and whose shape and dimensions are virtually the same as those of the connecting element (6) of the bone anchor (2), wherein a drill guide (12) is provided adjacent to each of said recesses (11) on the drilling template (10) that allows a drill to be appropriately guided in order to make drill holes in the jaw (1,17).

A mandibular positioning facial retrognathism orthodontic system and a design method thereof are disclosed. The orthodontic system includes a maxillary shell-like dental appliance having a shell-like body, a protrusion portion protruding toward an opposite jaw is disposed at a posterior area corresponding to the shell-like body, a traction portion is disposed at a labial side of the shell-like body, and a retaining portion configured for fastening with a retaining attachment is disposed at the posterior area corresponding to the shell-like body. The protrusion portion is engaged with the posterior area of a mandibular for occlusal reconstruction, so that mandibular incisors are aligned with maxillary incisors. The design method is a design method for the mandibular positioning facial retrognathism orthodontic system, which can provide a treatment-specific orthodontic system, thereby achieving treatment of mandibular positioning facial retrognathism.

An orthodontic appliance is provided and includes: a base member fixed to two or more screws implanted in a vicinity of median palatine suture of a palate bone; an arm-shaped arm member having a first connecting portion connected to the base member and a second connecting portion located in a vicinity of palatal side of a tooth; and a traction member that is made of an elastic wire material and pulls a tooth as the traction target. The traction member has a traction base portion, a traction fixation portion, and a traction force generation portion. The traction fixation portion has a bent portion in which the wire material extending along dentition is plastically deformed and bent toward a tooth root side. The bent portion is hooked on a protruding portion protruding to a palate side in a bracket.
