Abstract
The utility model discloses a half crown adds horizontal palate pole device, including half crown of two laminating tooth lingual surfaces and the horizontal palate pole that is used for connecting two half crowns, half crown cooperation tongue side is held in the palm groove or tongue side buccal tube and is used together, be provided with the net on the bonding face of half crown, half crown and tongue side are held in the palm groove or tongue side buccal tube structure as an organic whole. The utility model discloses, simple process holds in the palm groove and the buccal tube also is difficult for droing, and half crown and tooth bonding's dynamics is great simultaneously, has reduced the dropout rate.
Description
Technical Field
The utility model relates to the technical field of orthodontic treatment, in particular to a half-crown horizontal palate bar device.
Background
In orthodontic treatment, a cross palatal bar is a device for maintaining the width of a dental arch with moderate anchorage which is clinically common in orthodontic treatment. Often cooperate finished product belt ring or casting belt ring to use together, if need the cooperation hold in the palm groove and buccal tube, need hold in the palm groove and belt ring welding shaping with the finished product, process flow is not only loaded down with trivial details, and finished product thickness has also increased patient foreign body sensation, and the welding also can produce the risk that drops, holds in the palm the dynamics that groove and belt ring and tooth bonded less, drops easily. But also can not break through the limitation that the transparent appliance is difficult to control the width and the vertical direction of the dental arch.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a half crown adds horizontal palate bar device to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a half crown and transverse palate rod device comprises two half crowns attached to the lingual surfaces of teeth and a transverse palate rod used for connecting the two half crowns, wherein the half crowns are used together with lingual brackets or lingual buccal tubes, grids are arranged on the bonding surfaces of the half crowns, and the half crowns and the lingual brackets or the lingual buccal tubes are of an integrated structure.
Preferably, the bonding surface of the half crown is also provided with numbers for identifying tooth positions.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model has simple process, the bracket and the buccal tube are not easy to fall off, and the half crown is carved with the grids and the tooth positions, thereby increasing the bonding force and greatly reducing the falling rate;
2. the utility model discloses, can break through transparent ware control dental arch width of rescuring and perpendicularly control the difficult limitation.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a half crown adds horizontal palate rod device, includes two half crowns 2 of laminating tooth lingual surface and is used for connecting two horizontal palate rod 1 of half crown 2, and half crown 2 cooperates lingual cheek pipe to use jointly, is provided with net 4 on half crown 2's the bonding face, and half crown 2 and lingual cheek pipe structure as an organic whole.
Specifically, the number 3 is arranged on the bonding surface of the half crown 2, so that the tooth position can be conveniently matched, and the bonding force is increased.
Example 2
Referring to fig. 4, a half crown and horizontal palate rod device comprises two half crowns 2 attached to the lingual surfaces of teeth and a horizontal palate rod 1 for connecting the two half crowns 2, wherein the half crowns 2 are used together with lingual brackets, a grid 4 is arranged on the bonding surface of the half crown 2, and the half crown 2 and the lingual brackets are of an integral structure.
Specifically, the number 3 is arranged on the bonding surface of the half crown 2, so that the tooth position can be conveniently matched, and the bonding force is increased.
The working principle is as follows: the same tooth position is matched and fixed according to the numbers on the bonding surface of the half crown 2, the half crown 2 can be used together with a lingual bracket or a buccal tube, and the limitation that the transparent appliance is difficult to control the width of the dental arch and control the dental arch vertically can be broken through.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
