Detailed Description

the following describes embodiments of the present invention with reference to the drawings.

as shown in fig. 1, the lip stop-fitted mandibular arch device comprises: an arch expansion component and a lip block component.

an expansion bow assembly comprising:

The tongue 11, generally U-shaped, has an outward pre-expansion force.

two first molar belt rings 12 are respectively arranged at two ends of the U-shaped opening of the tongue arch 11, and when the first molar belt rings 12 are used specifically, the model taking manufacturing is needed according to the shape of individual teeth so as to be matched with the shape of the individual teeth.

And the lingual expansion arch wire 13 is arranged on the inner side of the U-shaped area of the lingual arch 11, one end of the lingual expansion arch wire 13 is fixedly connected with the first molar belt ring 12, the other end of the lingual expansion arch wire extends along the lingual direction of the teeth, and the lingual expansion arch wire 13 has expansion force towards the direction far away from the lingual direction so as to expand a plurality of teeth on two sides of the lower jaw.

A lip stop assembly comprising:

a labial arch 14 with a first molar mesial U-shaped curve, which is bent with a 1-1.2mm steel wire.

Two lip stops 15 detachably provided on the labial arch 14 at a section corresponding to the vestibular sulcus position of the anterior teeth area. The lip block 15 is made of a resin base.

In other embodiments, the labial arch 14 has a V-shaped curve 17 at a position corresponding to the middle of the lower central incisor, and two labial stoppers 15 are provided on the left and right sides of the V-shaped curve 17, respectively.

The labial arch 14 is bent using 0.5-0.7mm steel wire (or beta titanium wire).

After wearing, the two first molar belt rings 12 are sleeved on the two first molars, and a tongue bow with a first molar, which is bent in a U shape at the middle part is provided, and the width, the length and the height of the tongue bow are adjusted in the three-dimensional direction by utilizing the U-shaped bend. The U-shaped curve also carries an expansion force outward from the lingual side.

The expanded arch wire with the spring ring 16 corresponds to the area of the cuspid-first premolar-second premolar region (which may be the corresponding deciduous teeth in the mixed dentition stage) in the direction of the high point gum of the lingual contour of the teeth.

Two first fixing blocks 18 are fixed to the outer sides of the first molar belt rings, respectively, and two second fixing blocks 19 are fixed to the lingual sides of the first molar belt rings, respectively. Two tail ends of the tongue arch 11 are detachably connected with the second fixing block respectively, and the tail ends of two sides of the lip arch 14 are detachably connected with the two first fixing blocks. The detachable connection means described herein are shown in fig. 2, 3 and 4:

Here, the first fixed block 18 and the second fixed block 19 have the same structure, and thus the structure of the first fixed block 18 will be described as an example. As shown in fig. 4, the first attachment block 18 has two raised ridges each having a first through hole 181 therein and an archwire receiving slot 182 intermediate the two ridges.

the ends of the labial arch and the lingual arch have forked shaped fixtures, as shown in fig. 2 and 3, which comprise three fixing wires, wherein the fixing wire is called a bending fixing wire 142 at the center and the transverse limiting wires 141 at both sides of the bending fixing wire.

The two transverse limiting wires 141 are respectively inserted into the two first through holes 181, and after the two transverse limiting wires are inserted, the movement of the tail ends of the labial arch and the lingual arch in the left and right directions can be limited, and the arch wires of the labial arch and the lingual arch can be limited to rotate.

the bent fixing wire 142 passes through the archwire receiving groove 182 and is bent upward or downward at the rear end of the first fixing block 18 and caught behind the first fixing block 18. Thereby limiting the forward movement of the forked securing member out of the first securing block 18. In operation, the forked securing member is first inserted into the first securing block in the unfolded state of fig. 2, and then the bent securing wire 142 is bent upward or downward using forceps or other grasping instrument. The upward or downward orientation referred to herein is relative to the orientation of the first mounting block as shown in fig. 4. The purpose is to cause the bent fixing wire 142 to be bent behind the ridge of the first fixing block to be caught.

In order to reduce the exposure of the transverse limiting wire 141 from the rear end of the first through hole 181, the length of the bending fixing wire is greater than that of the transverse limiting wire.

When the labial arch or the lingual arch needs to be taken down, the bent fixing wire 142 is straightened back, and then the arch wire is pulled forward, so that the forked fixing piece can be separated from the first fixing block or the second fixing block.

the above-mentioned detachable structure is adopted at the end of the labial arch and the end of the tongue arch. Therefore, the arch wire with a new size can be replaced according to the growth condition of the oral cavity. In addition, the lip arch or the tongue arch can be independently used, because the lip habit of usually expanding the arch of the lower jaw or biting the lower jaw is overcome, the time of finishing the two items is inconsistent, the utility model discloses can mark the back at an item, take off corresponding arch wire, improve the comfort of the wearer.
