However, there is a type of maxillary ectopic impacted canine clinically, which is mostly in a eruption state in oral examination, and the labial similar to the arhat is located above the adjacent teeth, most commonly located above the lateral incisors or the first premolar teeth, so this type of impacted is defined as a special impacted type-labial ectopic overlap impacted. The maxillary labial ectopic overlapping impacted cuspids are represented as image overlapping of impacted cuspids and adjacent teeth on the examination of full-mouth curved surface fault slices, and the following 2 objective indexes are adopted for definition according to the past research and clinical correction experience. Angle β: an angle formed by the long axis of the impacted canine tooth and the long axis of the adjacent tooth at the dental crown end is defined as a beta angle; actual overlap area: and (3) the overlapping image area of the maxillary impacted canine teeth when the impacted canine teeth are actually overlapped with the adjacent canine teeth. When the beta is less than or equal to 25 degrees and the actual overlapping area is more than or equal to 50 percent of the total image area of the maxillary impacted canine teeth, the type of impacted is defined as a special impacted type-overlapping ectopic impacted.

Because this kind of it is obvious to misplacing to hinder living cusp lip in traditional fixed mode of correcting, the arch wire can not be brought into and hinders living cusp bracket groove to conventional correction, can't utilize the force couple apart from realizing the bulk movement of cusp, if the arch wire does not bring into the groove and only exert the pure traction force to the dental crown, can cause the slope of cusp to move the backward movement of dental crown and dental root promptly, increase the difficulty of later stage dental root axis of uproar and the risk of root absorption. In modern recessive correction, the impacted canine and the adjacent teeth are overlapped and dislocated, and the correction braces cannot wrap the impacted canine and the adjacent teeth well, so that the expected movement effect cannot be achieved, and the correction type is clinically troublesome.

The utility model aims to provide a moving track for overlapping impacted cuspids on the labial side of an upper jaw, which aims to solve the problems in the prior art, the labial arch at the impacted cuspids is arranged into a structure in a shape like a Chinese character 'ji', other structures do not need to be added, the manufacturing process is simple, the bottom edge of the structure in the shape like the Chinese character 'ji' penetrates through a first bracket on the impacted cuspids to form a traction track of the first bracket, and the first bracket is pulled by the traction structure to drive the impacted cuspids to move, so that the impacted cuspids can integrally move, are separated from adjacent teeth, and then are brought into the dental arch, and further can be corrected.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

As shown in figures 1-2, the utility model provides a moving track of a maxillary labial overlapped impacted canine 8, which comprises a labial arch, a first bracket 2 arranged on the impacted canine 8 and a second bracket 3 arranged on a non-overlapped adjacent tooth of the impacted canine 8, wherein when the labial arch is bent, an impression is taken to make a plaster model, an individualized labial arch is bent on the model by an arch wire according to the original dental arch shape, and fine adjustment is carried out in the mouth. It should be noted that, since the adjacent tooth next to the impacted canine 8 is not necessarily provided with the first bracket 2, the aforementioned non-overlapping adjacent tooth is not necessarily the adjacent tooth next to the impacted canine 8, but may be a distal adjacent tooth, that is, the second bracket 3 is not necessarily mounted on the adjacent tooth next to the impacted canine 8; furthermore, the adjacent tooth fingers are not necessarily one, and two or more adjacent tooth fingers may be provided. The first bracket 2 and the second bracket 3 can be bonded on the dental crown according to the existing method, and it should be noted that the first bracket 2 can slide along the labial arch, and the second bracket 3 is fixedly ligated with the labial arch. The labial arch comprises a structure 1 in a shape like a Chinese character 'ji', the structure 1 in a shape like a Chinese character 'ji' is arranged at the position of the impacted cuspid 8, if the inner side of the structure 1 in a shape like a Chinese character 'ji' spans the adjacent tooth of the impacted cuspid 8, the second bracket 3 is not arranged on the adjacent tooth, and the second bracket 3 is arranged on the more far-end adjacent tooth. The inverted V-shaped structure 1 comprises a bottom edge 11 and a wing edge 12, wherein the wing edge 12 is ligated with the second bracket 3, the bottom edge 11 passes through the first bracket 2 and forms a traction track of the first bracket 2, and the first bracket 2 is connected with a traction structure 4. The traction structure 4 can be made of arch wire and has a certain pretension force, and can also be a chain leather ring or other structures. Utilize and pull structure 4 and pull first support groove 2 and drive impacted cusp 8 and remove to realize impacted cusp 8's bulk movement, make it break away from with the adjacent tooth that overlaps, adopt the conventional means of correcting to come into the dental arch again, and then can correct the impacted cusp 8 to the maxillary labial side overlapping.

The utility model can ensure the complete separation of the impacted cuspid 8 and the adjacent teeth to the maximum extent through the integral movement of the impacted cuspid 8, thereby bringing convenience to subsequent correction, reducing the difficulty of the dental root axis alignment at the later stage and correcting the impacted cuspid 8 under the condition of avoiding tooth extraction.

The labial arch can adopt stainless steel round wire, for example, select 0.016inch small-size stainless steel round wire, the reason that does not adopt big size stainless steel square wire is that CBCT inspection finds that the sclerotin of the labial side and the adjacent lingual side of this type of impacted cusp 8 is weaker, the tooth is close to the cortex of the bone, the cortex resistance is huge and is unfavorable for the movement of the impacted cusp 8, the gap between the stainless steel round wire and the first bracket 2 allows the impacted cusp 8 to do certain inclined movement, and the difficulty of the movement of the impacted cusp 8 can be reduced. It should be noted that the use of 30g of light traction by the traction structure 4 is also based on the above considerations of excessive cortical bone resistance and reduced anchorage consumption. When the crown of the impacted cuspid 8 moves to the far middle of the lateral incisor and the near middle of the first premolar, the subsequent process of taking the impacted cuspid 8 into the dental arch by adopting the conventional correction means is relatively simple (preferably, the auxiliary jaw traction helps the cuspid move in place). The impacted canine tooth 8 is simple to apply force by traction each time, the impacted canine tooth 8 moves along the labial arch in the whole moving process, the palatal pressure cannot be further applied to the adjacent teeth, and the subsequent correction difficulty is reduced for the further correction of the adjacent teeth in the future.

The wing edge 12 extends at least to the first molar, on which the second bracket 3 is arranged as well as on each tooth between non-overlapping neighbouring teeth of the first molar and the impacted canine 8. Therefore, the device of the utility model can utilize the maxillary whole dentition or partial dentition as the anchorage to move the impacted canine 8, and particularly, the greater the crowdedness of the teeth, the greater the mutual antagonistic force between the teeth, the more stable the anchorage can be obtained.

The limb 12 is fitted to all the second brackets 3 and no traction is applied, i.e. after the limb 12 has been fitted, the labial arch is required to fit as completely as possible to all the bracket slots without applying any orthodontic force to the teeth.

The n-shaped structure 1 is connected with an anchorage structure 6, the anchorage structure 6 is generally connected at the convex position of the n-shaped structure 1, and the other end of the anchorage structure is fixed on a lip arch or a second bracket or a fixed node additionally arranged on the lip arch. The anchorage structure 6 may be an arch wire additionally provided to support or pull the zigzag structure 1, or may be another form of anchorage structure 6, in short, in order to ensure the stability of the zigzag structure 1.

The anchorage structure 6 and the traction structure 4 may be located on the same side of the impacted cuspid 8, that is, the direction in which the traction structure 4 pulls the impacted cuspid 8 to move is the direction in which the anchorage structure 6 is disposed, and at this time, the anchorage structure 6 should have a certain pulling capability. The anchorage structure 6 and the traction structure 4 can also be located on different sides of the impacted cuspid 8, at this time, the direction of the traction structure 4 for drawing the impacted cuspid 8 to move is opposite to the direction of the anchorage structure 6, and the anchorage structure 6 should have certain supporting capability.

The bottom edge 11 can be provided with a drawing hook 5 at a position close to the corner, and the drawing hook 5 is fixed on the bottom edge 11 and cannot move so as to achieve the aim of connecting other structures. The towing hook 5 can be used for connecting the towing structure 4 and can also be used for connecting the anchorage structure 6.

The anchorage structure 6 may comprise a ligature wire, one end of which is connected to the towing hook 5 and the other end of which is connected to the second bracket 3 or the wing 12 remote from the n-shaped structure 1, so that the ligature wire forms the anchorage structure 6 for pulling the n-shaped structure 1, and at this time, the ligature wire and the towing structure 4 are located on the same side of the incisor 8.

The limb 12 may also be provided with a further hook 7, to which further hook 7 the other end of the ligature wire is connected, i.e. the ligature wire is connected to the second bracket 3 or the limb 12 via the further hook 7.

The towing structure 4 may comprise a chain leather collar, one end of which is connected to the towing hook 5 and the other end of which is connected to the first bracket 2. For example, the first bracket 2 provided on the retraction hook 5 and the impacted canine tooth 8 may be retracted with a light force of the chain leather ring 30g, and the chain leather ring may be replaced once per month for a further examination.

The principle and the implementation mode of the utility model are explained by applying a specific example, and the description of the embodiment is only used for helping to understand the method and the core idea of the utility model; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the utility model.
