Description

Orthodontic traction accessory

Technical Field

The utility model relates to a medical appliance used in an oral cavity, in particular to an orthodontic traction accessory.

Background

The lingual button is a common orthodontic accessory in orthodontic correction. The tongue side buckles are divided into two types, namely bonding type tongue side buckles and welding type tongue side buckles according to different base plates. In oral clinical treatment, orthodontic treatment is a common treatment project, and aims to correct malocclusion and irregular tooth arrangement of a patient, so that teeth are tidy, attractive and stable.

In order to better correct the teeth, sometimes a lingual button is adhered to the teeth, and then the elastic rubber ring and the lingual button apply force to the teeth to be corrected, so as to achieve the purpose of correcting the teeth. However, the tongue side buckle can influence the wearing of the invisible braces on the teeth after being adhered to the teeth. In order to wear the invisible braces without affecting the adhesion of the lingual buttons on the teeth, a notch is usually formed on the invisible braces corresponding to the lingual buttons to be adhered, and the notch is used for the lingual buttons to avoid affecting the wearing of the invisible braces, but the integrity and the stress release of the invisible braces are affected by the operation.

In the process of stealth correction, it is often necessary to apply low compressive forces to the teeth. In the clinical application process, holes are often formed in the invisible tooth socket, and then the lingual buttons extend out of the holes of the tooth socket to assist the anchorage nails to apply vertical traction force. This mode of operation has two disadvantages: firstly, the operation is relatively complicated; secondly, the fitting performance of the partial tooth socket is affected after the tongue side buckle is placed.

In orthodontic treatment, it is sometimes necessary to apply a depressing force to the teeth, sometimes necessary to apply a forward force to the teeth, sometimes necessary to apply a rearward force, and sometimes necessary to apply a combined force. In the invisible correcting process, holes are formed in the invisible braces, and then the lingual buttons extend out of the holes of the braces to assist the anchorage nails to apply vertical traction force. However, the conventional lingual button sometimes falls off when a force is applied, and particularly, the problem is more likely to occur when a combined force and a forward force are applied.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides the orthodontic traction accessory which is not required to be adhered to teeth and is not easy to fall off after an elastic rubber ring is hung.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the orthodontic traction accessory comprises a base, wherein the base is a rhombic base or an oval base, and a drag hook is arranged on the plane perpendicular to the base on the base.

As a preferable scheme of the utility model, the thickness of the base is 0.5-1.2 mm; the side length of the base is 3.0-4.6 mm; the total length of the draw hook is 1.2-2.8 mm; the bending radius of the draw hook is 0.5-1.3 mm.

In a preferred embodiment of the utility model, the base and the edges of the retractor are both in a circular arc transition.

In a preferred embodiment of the present invention, the base and the retractor are integrally formed.

The utility model has the technical effects that: when the orthodontic traction accessory is used, the inner side of the invisible tooth socket is required to be provided with the inward-concave rhombic groove or the elliptical groove, the outer side of the invisible tooth socket forms the outward-convex rhombic protrusion or the outward-convex elliptical protrusion, the middle part of the rhombic groove or the elliptical groove of the invisible tooth socket is provided with the strip-shaped through hole, then the drag hook buckled on the tongue side penetrates through the strip-shaped through hole on the invisible tooth socket, the rhombic base or the elliptical base is clamped in the rhombic groove or the elliptical groove of the corresponding invisible tooth socket, the tongue side can be limited and restrained through the rhombic groove or the elliptical groove and the strip-shaped through hole on the invisible tooth socket, and the base buckled on the tongue side is not required to be bonded on teeth, so that the attractiveness of the invisible tooth socket on teeth is not influenced, and the tongue side can be fixedly restrained.

Detailed Description

The utility model is described in further detail below with reference to the figures and the detailed description.

As shown in figure 1, the orthodontic traction accessory comprises a base 1, wherein the base 1 is a rhombic base or an oval base, and a drag hook 2 is arranged on the base 1 and is perpendicular to the plane of the base 1. In this embodiment, base 1 is the positive quadrangle base, and the edge of base 1 and drag hook 2 is the circular arc transition, avoids the edge of base 1 and drag hook 2 to cause the scratch to tooth surface or oral mucosa.

The thickness of the base 1 is 0.5-1.2mm, the side length of the base 1 is 3.0-4.6mm, the base 1 with the size is just smaller than the width of one tooth surface, and the base 1 can be pressed on the base 1 through the diamond-shaped groove or the oval-shaped groove of the invisible tooth socket 3, so that the base 1 is tightly attached to the tooth surface. The total length of the drag hook 2 is 1.2-2.8mm, the bending radius of the drag hook 2 is 0.5-1.3mm, the drag hook with the size can meet the requirement that the elastic rubber ring is connected with the drag hook 2, the occupied space is small, and the elastic rubber ring is not easy to fall off after being hung on the drag hook 2. The base 1 and the draw hook 2 are integrally formed, and the base 1 and the draw hook 2 are integrally formed through a die during manufacturing.

When the orthodontic traction accessory is used, the inner side of the invisible tooth socket 3 is provided with a diamond groove or an oval groove, the outer side forms a convex diamond bulge or an oval bulge, a strip-shaped through hole is arranged in the middle of the diamond-shaped groove or the oval groove of the invisible facing 3, then the draw hook 2 buckled on the lingual side passes through the strip-shaped through hole on the invisible facing 3, the diamond-shaped base or the oval base is clamped in the corresponding diamond-shaped groove or oval groove of the invisible facing 3, the base 1 is pressed through the diamond-shaped groove or the oval groove of the invisible facing 3, and then the base 1 is tightly attached to the tooth surface, so that the lingual buttons can be limited and restrained through the rhombic or elliptic grooves and the strip-shaped through holes on the invisible braces 3, the base 1 of the lingual buttons does not need to be bonded on teeth, the appearance of the invisible braces on the teeth is not influenced, and the lingual buttons can be fixed and restrained.

The orthodontic traction accessory mainly sets the base 1 of the tongue side buckle to be a non-circular base, the non-circular groove is formed in the invisible facing 3, and when the non-circular base of the tongue side buckle is clamped in the non-circular groove of the invisible facing 3, the tongue side buckle cannot rotate. Therefore, the base 1 of the lingual button only needs to be set to be a non-circular base, such as a diamond base or an oval base in the embodiment, other non-circular bases similar to a diamond or an oval can be adopted, and the invisible facing 3 is provided with a diamond groove, an oval groove, a non-circular groove similar to a diamond or an oval in a corresponding shape.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, 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 modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
