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

Furthermore, the two branches on the left support are connected through a left connecting rod, and the two branches on the right support 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 invention has the beneficial effects that:

1. compared with the existing arch expander, the arch expanding force is applied to the teeth, the arch expanding implant anchorage device can apply larger arch expanding force, and the arch expanding success rate is better; and the arch expansion force is parallelly applied to the palatine bones at two sides of the palatal center slit through four screws, and the palatal center slit after arch expansion is parallel front and back, so that the defect that the expanded center slit of the existing arch expander is V-shaped is avoided, the problem that the arch expansion of the existing reamer is easy to cause the buccal inclination of teeth is solved, and the arch expansion effect is better.

2. The left bracket and the right bracket of the arch expansion implantation anchorage device can be used as anchorage for applying correction force to teeth, and the orthodontic accessories adhered to the palatal side or/and the buccal side of the teeth are connected with the branches on the left bracket and the right bracket through rubber bands, so that traction force in the forward direction or/and the backward direction and the gum direction can be applied to the teeth, and the teeth can be corrected by applying the correction force to the palatal side.

3. The arch expanding implantation anchorage device is characterized in that the orthodontic accessory stuck to the palate side or the cheek side of a tooth is in opposite connection with the corresponding connecting rod (the left connecting rod or/and the right connecting rod) through the rubber band, so that the force of pressing down the tooth can be exerted.

Detailed Description

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

As shown in the figure, the arch-expanding planting anchorage device of the embodiment comprises a left support 1 and a right support 2, wherein each of the left support and the right support is composed of a base block 3, at least one branch 4 connected with the base block, and a protrusion 5 arranged on the branch and used for connecting a rubber band, two through holes 6 are arranged on each base block, and a screw 7 used for fixing the base block on a hard palate is arranged in each through hole. In the specific implementation, the base block, the branches and the bulges are integrally formed by casting.

Expand bow and plant anchorage device still includes two guide bars 8 of parallel on the base block of left socle and right branch frame and with the base block threaded connection of left socle and right branch frame and with the parallel screw rod 9 of guide bar, guide bar and left socle and right branch frame sliding fit, the screw rod is located between two guide bars, and the screw rod is located between two via holes on the base block. The screw threads on the screw rod and connected with the left support and the screw threads on the screw rod and connected with the right support are opposite in screw thread rotating direction; the middle part of the screw rod is provided with a counter bore 10 used for being connected with a spanner, the spanner is inserted into the counter bore to rotate the screw rod, and then the left support and the right support can be pushed to symmetrically move towards two sides, so that the bow expansion is realized.

In the arch expansion implantation anchorage device in the embodiment, the arch expansion force is directly transmitted to the screw through the base block of the support, the screw transmits the arch expansion force to the palatine bone, and compared with the existing arch expansion device in which the arch expansion force is applied to teeth, the arch expansion anchorage device in the embodiment can apply larger arch expansion force, the arch expansion efficiency is higher, and the arch expansion success rate is better. And the arch expanding force is parallelly applied to the jaw bones at two sides of the palatal center slit through four screws, and the palatal center slit after arch expansion is parallel front and back, so that the defect that the expanded center slit of the existing arch expander is V-shaped is avoided, and the arch expanding effect is better.

In this embodiment, two branches are respectively disposed on the left support and the right support, 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.

In the arch expanding implantation anchorage device, the left support and the right support can be used as anchorage for applying correction force to teeth, and the orthodontic accessories adhered to the palatal side of the teeth are connected with the branches on the left support and the right support through rubber bands, so that forward or/and backward traction force can be applied to the teeth, and the correction force can be applied to the palatal side to correct the positions of the teeth. The correction force is transmitted to the palatine bone through the bracket and the screw, and the stability of anchorage is good.

As an improvement to the above embodiment, the two branches on the left bracket of the arch-expanding planting anchorage device of the present embodiment are connected by a left connecting rod 11, and the two branches on the right bracket are connected by a right connecting rod 12. The improvement leads the orthodontic accessory stuck on the palatine side or the buccal side of the tooth to be in opposite connection 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 13 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, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, 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 modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
