The invention improves the traction device.
Specifically, the securing strap ring structure 10 is bonded to the teeth by glass ions, specifically to the first deciduous molars or second deciduous molars or first bicuspids or second bicuspids or first permanent molars on both sides, acting as a retention and enhancing anchorage.
The outer sides of the two-sided fixing band ring structures 10 are fixedly connected with the two ends of the dental socket arch 22, and the inner sides of the two-sided fixing band ring structures 10 are fixedly connected with the two ends of the retainer 21.

Specifically, the porous traction structure 30 is arched in a cross shape, and the porous traction structure 30 arches toward the lingual side, thereby improving the comfort in the oral cavity. The porous traction structure 30 of the present embodiment includes two traction plates 31 fixed in a crossing manner, the traction plates 31 are elongated, preferably, the traction plates 31 of the present embodiment are elongated rectangular traction plates with rounded corners, the traction plates 31 are provided with a plurality of through holes 311, and the plurality of through holes 311 are arranged along the extending direction of the traction plates 31. More specifically, the cross-shaped porous traction structure 30 is cast from two pieces of stainless steel having a width of about 1.5mm to 2.0mm, a length of about 2.0cm to 4.0cm, and a thickness of about 0.8mm to 1.2mm, and small hole structures having diameters of about 0.8mm are respectively formed in the middle, and the interval between the holes is about 0.8mm to 1.0mm, so that a porous cast structure is finally formed. The porous casting structure is crossed at the position of the tooth-missing position, which is 3mm-5mm, of the alveolar ridge, so as to form an arched cross structure. The traction plate 31 has a rectangular cross section, the dental socket arch 22 has a square cross section, and the surface contact is more fit and the welding is more fit.
The elongated traction plate 31 is used for conveniently forming the through holes 311, and the number of the through holes 311 in this embodiment is plural, specifically, the through holes 311 may be arranged at equal intervals along the length direction of the traction plate 31, may be arranged at unequal intervals, and may also be arranged at equal intervals in a straight line. The number of the through holes 311 may be 2, 3,4, etc. according to actual needs, in a specific embodiment, the number of the through holes 311 is 3, and the 3 through holes 311 may be aligned in line and arranged at equal intervals along the length direction of the traction plate 31, in another specific embodiment, the 3 through holes 311 may be further arranged in a triangle, and may be arranged at equal intervals. It can be understood that the through holes 311 are mainly used for connecting the buried teeth through the traction wires, and the positions of the through holes 311 are adjusted to adjust the traction direction, so that the specific arrangement and the number of the through holes 311 can be adjusted according to the clinical actual requirements.
Specifically, the traction plate 31 of the present embodiment is a rectangular traction plate 31, wherein four corners of the rectangle are preferably rounded corners, so as to avoid scratching the inner wall of the oral cavity and protect the oral mucosa.
The two traction plates 31 of the present embodiment are cross-fixed to form an arched cross-shaped structure, and preferably, the two traction plates 31 are cross-fixed by welding at the time of production. The traction plate 31 uses the welding intersection as the center, through holes 311 are formed in two ends of the traction plate 31, and the traction wire 40 can be connected to the through holes 311 at any position according to actual conditions.
Since the angle at which the two traction plates 31 intersect is not fixed, one end of the traction plate 31 can be fixed to the first connecting portion 211 when the angle is large.

Because the porous traction structure 30 is positioned in the lower space of the embedded teeth, the porous traction structure 30 arches towards the lingual side to promote the sense of use of the porous traction structure 30 in the oral cavity.
Specifically, the position at which the traction wire 40 is attached to the through-hole 311 is correlated with the three-dimensional position of the buried tooth, in which the crown of the buried tooth faces labial side, the traction wire 40 is attached to the through-hole 311 near the retainer 21, the crown of the buried tooth faces palate side, and the traction wire 40 is attached to the through-hole 311 near the alveolar arch 22.
Because the intersection angle of the two traction plates 31 is customized according to the angle of the embedded teeth of the patient, the traction direction and the traction angle of the embedded teeth are more suitable, so that the speed of traction of the embedded teeth is increased, and the correction time is shortened.
Because the porous traction structure 30 is arched and cross-shaped, as shown in fig. 4, in another embodiment, two buried teeth can be simultaneously pulled, and the two buried teeth are respectively and fixedly connected with the porous traction structure 30 through the traction wires 40, and the two teeth can be simultaneously pulled by adjusting the angle of the porous traction structure 30 and the position of the through hole 311 connected with the porous traction structure 30.
In other embodiments, the two traction plates 31 may be integrally formed, and the gaps may be reduced relative to welded fixation to reduce hidden and bacteria growth.
