[0004] The technical problem to be solved by this utility model is to provide anterior tooth shaping clip to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The solution to the technical problem of this utility model is:

[0006] Anterior tooth shaping clip, having a first direction, the anterior tooth shaping clip includes:

[0007] Two clamping arms are arranged crosswise and hinged in the middle. The hinge axis of the two clamping arms is parallel to the first direction. The two ends of the clamping arms are respectively set as an operating end and a clamping end. A molded sheet abutment structure is installed at the clamping end.

[0008] A clamping and retaining elastic element is disposed between the two clamping arms, and the clamping and retaining elastic element brings the two clamping ends closer to each other.

[0009] As a further improvement to the above technical solution, the molded sheet abutment structure is provided with tooth abutment surfaces, and the two tooth abutment surfaces are arranged opposite to each other. One of the tooth abutment surfaces is arc-shaped, and the other tooth abutment surface includes two intersecting abutment surfaces, which are arranged at an angle.

[0010] As a further improvement to the above technical solution, the included angle between the two abutting surfaces is 80°-100°.

[0011] As a further improvement to the above technical solution, the molding sheet abutment structure is a silicone component.

[0012] As a further improvement to the above technical solution, the clamping and retaining elastic element is a spring sheet.

[0013] As a further improvement to the above technical solution, the clamping and retaining elastic element is a helical spring.

[0014] As a further improvement to the above technical solution, an elastic adjustment mechanism is also included, the elastic adjustment mechanism comprising:

[0015] An adjusting screw, the adjusting screw being fixed to the operating end of one of the clamping arms;

[0016] An adjustment knob, which is threadedly connected to the adjustment screw;

[0017] Both ends of the clamping and retaining elastic element are respectively connected to the adjusting knob and the operating end of the other clamping arm.

[0018] As a further improvement to the above technical solution, the outer periphery of the adjustment knob is provided with anti-slip texture.

[0020] As a further improvement to the above technical solution, the operating end is provided with an operating center surface, and the clamping end is provided with a clamping center surface. The operating center surface and the clamping center surface are parallel and both perpendicular to the first direction. In the first direction, the operating center surface and the clamping center surface are spaced apart so that the clamping end and the operating end are staggered in the first direction.

[0021] The beneficial effects of this invention are as follows: When medical personnel control the operating ends of the two clamping arms to move closer together, the clamping ends of the two clamping arms move away from each other. Simultaneously, the clamping and holding elastic element deforms, accumulating elastic potential energy. When the medical personnel remove the external force applied to the operating ends, the clamping and holding elastic element releases its elastic potential energy, causing the clamping ends of the two clamping arms to move closer together. The forming piece at the clamping end abuts against the tooth, clamping the forming piece and the tooth. In practical use, this anterior tooth forming clamp can place a standard forming piece on the lingual side and clamp it using this anterior tooth forming clamp, forming a stable filling barrier to meet the filling needs of the lingual side.

[0028] Reference Figure 1 and Figure 2 Anterior tooth forming clamp, with a first direction. The anterior tooth forming clamp includes a clamping arm 100, a clamping and retaining elastic element 200, and an elastic force adjustment mechanism 300.

[0029] The number of clamping arms 100 is set to two, and the middle of the two clamping arms 100 are hinged to each other, and the hinge axis of the two clamping arms 100 is parallel to the first direction.

[0030] The two ends of the clamping arm 100 are respectively designated as a clamping end 101 and an operating end 102. When the clamping ends 101 of the two clamping arms 100 approach each other, the two operating ends 102 move away from each other. The operating end 102 is provided with an operating center surface, and the clamping end 101 is provided with a clamping center surface. The operating center surface and the clamping center surface are parallel and perpendicular to a first direction. In the first direction, the operating center surface and the clamping center surface are spaced apart.

[0031] Specifically, the clamping arm 100 includes a first handle 110, a first connector 120, a second connector 130, and a third connector 140 arranged sequentially. The operating end 102 is the end of the first handle 110, which is located on one side of the hinge of the clamping arm 100, while the first connector 120, the second connector 130, and the third connector 140 are located on the other side of the hinge of the clamping arm 100. The first connector 120 is fixedly connected to the end of the first handle 110 away from the operating end 102. The first connector 120 is inclined and gradually moves away from the first handle 110 towards the other clamping arm 100, and gradually shifts along the first direction. The second connector 130 is a straight component and extends from the clamping end 101 to the operating end 102. The third connector 140 extends towards the other clamping arm 100 and is perpendicular to the second connector 130. The clamping end 101 is the end of the third connector 140 away from the second connector 130. This arrangement causes the clamping end 101 and the operating end 102 to be staggered in the first direction. This staggered arrangement of the clamping end 101 and the operating end 102 in the first direction can avoid obstruction of adjacent teeth, ensuring that this anterior tooth shaping clamp can be used normally.

[0032] In this embodiment, the clamp arm 100 is made of metal, which can ensure the overall strength and service life of this anterior tooth forming clamp.

[0033] The clamping end 101 is fixedly equipped with a molded sheet abutment structure 103, which is made of silicone material and has good flexibility and conformability. The molded sheet abutment structure 103 has tooth abutment surfaces. One tooth abutment surface of the molded sheet abutment structure 103 is arc-shaped to fit the labial surface of the tooth, and the other tooth abutment surface of the molded sheet abutment structure 103 includes two intersecting surfaces at a 90-degree angle. The tooth abutment surface design can be further optimized according to different patient needs to provide a more stable positioning effect.

[0034] The clamping and retaining elastic element 200 and the elasticity adjustment mechanism 300 are disposed between the two clamping arms 100.

[0035] The elastic adjustment mechanism 300 includes an adjustment knob 310 and an adjustment screw 320. The adjustment screw 320 is fixedly installed on the operating end 102 of one of the clamping arms 100. The adjustment knob 310 is threadedly connected to the adjustment screw 320. When the adjustment knob 310 is rotated, it will move closer to or further away from the operating end 102 of the other clamping arm 100. A clamping and retaining elastic element 200 is disposed between the adjustment knob 310 and the other clamping arm 100. The clamping and retaining elastic element 200 is configured as a helical spring. Both ends of the clamping and retaining elastic element 200 abut against the adjustment knob 310 and the operating end 102 of the other clamping arm 100, respectively. The clamping and retaining elastic element 200 is used to ensure that the operating ends 102 of the two clamping arms 100 always tend to move away from each other, thereby ensuring that the clamping ends 101 of the two clamping arms 100 always tend to move closer to each other, so that the anterior tooth shaping clamp can maintain the clamping of the teeth.

[0036] Specifically, in this embodiment, the outer periphery of the adjustment knob 310 is provided with anti-slip texture. By providing anti-slip texture on the outer periphery of the adjustment knob 310, the slippage of the adjustment knob 310 by medical staff can be avoided, making it easier to operate.

[0037] In other embodiments, the clamping and retaining elastic element 200 may also be configured as a spring sheet. Those skilled in the art can select the specific structure of the clamping and retaining elastic element 200 according to actual needs.

[0038] In actual use, this anterior tooth shaping clamp can be used by placing a general shaping piece on the lingual side and holding it with this anterior tooth shaping clamp to form a stable filling barrier.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
