The palatal side bracket type implant anchorage of the utility model is fixed on the hard palate through screws when in use and is used as an anchorage for applying correction force to teeth; the orthodontic attachment stuck on the palatal side or the buccal side of the teeth is connected with the branch of the anchorage through the rubber band, so that the forward or/and backward traction force can be applied to the teeth, and the orthodontic force can be applied to the palatal side to correct the teeth.

Description

Palatal side bracket type implant anchorage

Technical Field

The utility model relates to an oral medical appliance, in particular to an orthodontic anchorage device.

Background

In the prior art, in orthodontics, an arch wire, a bracket, an elastic band, etc. are generally used to apply traction to teeth so as to move the teeth in a desired direction. In order for the teeth to reach the desired distance of movement, it is often necessary to reinforce the anchorage, the micro implant anchorage being the most common way. A commonly used implant anchorage is generally placed on the labial side of the teeth, especially the buccal side of the posterior teeth. However, in some cases, the implant anchorage on the posterior buccal side is difficult or even impossible to design, such as in cases where the maxillary sinus is too low, the inter-root distance is too small, and the like. To solve this problem, we have devised a palatal side bracket type implant anchorage device that can apply a force to a tooth from the palatal side of the tooth forward, backward or gingivally.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a palatal side bracket type implant anchorage to apply traction to teeth on the palatal side, so as to solve the technical problem of deformity of the front and rear positions of the teeth.

The utility model discloses anchorage is planted to palatal side support formula, which comprises a bracket, the support includes the base block and an at least branch of being connected with the base block, be provided with at least one arch that is used for connecting the rubber band on the branch, be provided with two at least via holes on the base block, be provided with in the via hole and be used for fixing the base block at the palatal screw of hard.

Further, the shape of the surface of the base block, which is attached to the palate, is matched with the shape of the surface of the palate.

Furthermore, the number of the branches is four, and the four branches are distributed in an X shape.

Furthermore, two branches on the left side of the four branches are connected through a left connecting rod, and two branches on the right side of the four branches are connected through a right connecting rod.

Furthermore, bulges for fixing rubber bands are arranged on the left connecting rod and the right connecting rod.

The utility model has the advantages that:

1. the palatal side bracket type implant anchorage of the utility model is fixed on the hard palate through screws when in use and is used as an anchorage for applying correction force to teeth; the orthodontic attachment stuck on the palatal side or the buccal side of the teeth is connected with the branch of the anchorage by the rubber band, so that the traction force in the forward direction or/and the backward direction and the gingiva direction can be applied to the teeth, and the teeth can be corrected by applying the correction force on the palatal side.

2. The utility model discloses anchorage is planted to palatal side support formula, the just right connection of connecting rod (left connecting rod or/and right connecting rod) rather than corresponding through the rubber band to the just orthodontic accessories who will paste in tooth palatal side/buccal side, can realize exerting the strength of holding down to the tooth.

Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in the figure, the palatal lateral bracket type implant anchorage device of the present embodiment includes a bracket, the bracket includes a base block 1 and at least one branch 2 connected to the base block, the branch is provided with at least one protrusion 3 for connecting a rubber band, the base block is provided with at least two through holes, and the through holes are provided with screws 4 for fixing the base block on the hard palate. In the specific implementation, the base block, the branches and the bulges are integrally formed by casting.

In this embodiment, the number of the branches is four, and the four branches are distributed in an X-shape. The branch positioned at the side of the rear tooth is connected with the orthodontic accessory on the front tooth through the rubber band, so that backward traction force can be applied to the front tooth, and the front tooth moves backward; the branches positioned at the front tooth side are connected with the orthodontic accessories on the back teeth through rubber bands, so that forward traction force can be applied to the back teeth, and the back teeth move forward. When in specific implementation, the number of branches and the distribution position on the base block can be reasonably adjusted according to the actual disease condition.

This embodiment palatal side support formula implantation anchorage, it passes through the screw fixation on hard palate during the use, and as exerting the anchorage of correcting the power to the tooth, on correcting the power and transmitting palatal bone through support, screw, anchorage's stability is good.

As an improvement to the above embodiment, the shape of the surface of the base block that fits the palate matches the shape of the surface of the palate, this improvement allows for greater comfort after the anchorage members are fixed to the palate.

As an improvement to the above embodiment, two branches on the left side of the four branches are connected by a left connecting rod 5, and two branches on the right side of the four branches are connected by a right connecting rod 6. The improvement leads the orthodontic accessory stuck on the palatal side or the buccal side of the tooth to be just connected with the corresponding connecting rod (the left connecting rod or/and the right connecting rod) through the rubber band, and can realize the force of pressing down on the tooth.

As a modification of the above embodiment, the left and right links are each provided with a protrusion 7 for fixing a rubber band. The position of the rubber band on the left connecting rod and the right connecting rod can be better limited by arranging the bulges.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
