Detailed Description

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

As shown in the figure, the bracket-free invisible tooth socket assembly comprises a tooth socket and accessories for fixing the tooth socket, wherein the tooth socket is provided with a groove matched with the shape of the accessories, and the accessories comprise a horizontal strip-shaped accessory 1 used for being pasted on a back tooth and a vertical strip-shaped accessory 2 used for being pasted on a front tooth. The vertical shape of the horizontal strip-shaped accessory is that the thickness of the horizontal strip-shaped accessory is gradually increased from the dental crown to the gum and then is extended in an equal thickness manner, and the horizontal shape of the horizontal strip-shaped accessory is changed into the thickness of the horizontal strip-shaped accessory is gradually increased from the far middle to the near middle and then is extended in an equal thickness manner; the mesial-distal direction is the direction indicated by the arrow in fig. 1, i.e. from the posterior teeth to the anterior teeth. The vertical shape of the vertical strip-shaped accessory is changed into a shape that the thickness of the vertical strip-shaped accessory is gradually increased from the dental crown to the gum and then is prolonged in an equal thickness mode.

In the bracket-free invisible facing assembly in the embodiment, the thickness of the horizontal strip-shaped accessory and the vertical strip-shaped accessory towards one end of the dental crown is gradually increased from the dental crown to the gum, so that the facing can be more easily sleeved on the tooth, the accessories can be more easily put into place in the groove in the facing, and the problem that the accessories and the facing are difficult to put into place due to the fact that the thickness of one end of the existing facing accessory towards the dental crown is large when the existing facing accessory is worn is solved.

And horizontal bar shape annex and vertical bar shape annex are the uniform thickness section of thickness towards the one end of gum, this part gets into behind the recess on the facing, make the annex can apply sufficient retention power to the facing, avoided the thin problem not enough to the facing retention power of annex, and the facing can apply sufficient control force to the tooth, and then solved current facing and rescued the far-middle slope removal of the cuspid dental crown that the in-process often appears, the nearly well slope removal of back tooth, the back tooth especially first permanent molar and the second permanent molar often can appear nearly well slope, the nearly problem of well dislocation.

And because the tooth socket is generally dislocated from the back to the front when dislocating, the thickness of the transverse strip-shaped accessory towards one end in the far direction is gradually increased from the far direction to the near direction, so that the tooth socket can be dislocated from the back to the front more easily.

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.
