fig. 2 is a schematic structural view of the improved device in the front traction mouth in the deciduous period of the present invention.

In the figure: 1. a base support; 2. a bending part; 3. a hook part is pulled; 4. a pad.

Detailed Description

In order to make the objects and advantages of the present invention more apparent, the present invention will be described in detail with reference to the following embodiments. It is to be understood that the following text is only intended to describe one or several particular embodiments of the invention, and does not strictly limit the scope of the claims specifically claimed.

The technical scheme of the utility model taking is as shown in figure 1, a suckling period place ahead pulls intraoral improvement device, including traction wire and base 1, base 1 is the type of wrapping up the crown of tooth entirely, base 1 includes the medial surface of arranging along, terminal surface and lateral surface, the traction wire includes drag hook portion 5 and the portion of bending 2 of arranging along, drag hook portion 5 is two hooks of arranging along, and the crooked opposite direction of two hooks, drag hook portion 5 sets up in base 1 lateral surface and the corresponding position department of suckling sharp tooth, portion of bending 2 is L shape, the side free end of L shape portion of bending 2 meets with drag hook portion 5, drag hook portion 5 uses with extraoral place ahead draw gear cooperation, the main limit free end of L shape portion of bending 2 extends to in the pad 4 of base 1 terminal surface, base 1 terminal surface that portion of bending 2 belonged to is provided with the plastic layer of congealing certainly; in the embodiment, the base 1 and the pad 4 are integrally formed, and the base 1 and the pad 4 are both manufactured by adopting a hard matrix negative pressure die with the thickness of 2.0 mm.

The manufacturing method of the improved device in the traction mouth in the front of the deciduous teeth period of the utility model is as follows: trimming the prepared upper model, and removing part of hard palate to make the upper model into a U shape; then, a template negative pressure pressing die with the thickness of 2.0mm is adopted, redundant parts are ground, a stainless steel wire with the thickness of 1.0mm is bent at the near-middle part of the deciduous canine tooth to form a draw hook part, and the bent part extends far and far into the pad; then self-setting plastics are added on the end face of the base at the position of the bending part, and the self-setting plastics can play a role in fixing the traction wire and can be opened and occluded at the same time; wherein the draw hook part is convenient to be matched with a traction device in front of the mouth.
