Description

Technical Field

[0001] The utility model relates to the technical field of dental wedges, in particular to a segmented wedge for dental use. Background Art

[0002] When filling the interproximal cavities of teeth, a forming sheet is used to assist in forming the interproximal shape, and a wedge is needed to make it fit the neck. Dental wedges are currently made of wood or plastic, in the shape of a triangular prism or a cone, which is adapted to the shape of the interproximal spaces of teeth. They are mainly used in conjunction with forming sheets, and are placed in the interproximal spaces of adjacent teeth during tooth filling and repair to make the forming sheet fit the tooth surface.

[0003] The wedges currently used in dentistry, regardless of their shape and material, are all stuck between two teeth by squeezing and pressurizing, which can easily damage the gums. At the same time, when the gap between the two teeth is too large, it is necessary to add wedges from the direction of the gums. Multiple wedges are used in a superimposed manner so that the wedges are squeezed and fixed in the direction of the crowns. After filling, the gap between the two teeth is too large, and an overhang will be formed near the edge of the tooth neck. At the same time, the wedge will fall into the oral cavity if it falls off accidentally, and there is a risk of accidental swallowing. Therefore, the present application provides a segmented wedge for dentistry to meet the needs. Utility Model Content

[0032] like Figures 1 to 5 As shown, an embodiment of the utility model provides a segmented wedge for dental use, including a dental wedge body 1 and a picking assembly 2, wherein the dental wedge body 1 includes a wedge body 101, two wedge sections 102 having different curvatures from the wedge body 101, a cushion 103 fixedly mounted on the two wedge sections 102, a handle area 104 formed by a circular appearance, an arc-shaped groove 105 formed by the free space between the wedge body 101 and the handle area 104, and a threading hole 106 opened inside the handle area 104, and the picking assembly 2 includes a perforating block 201, a connecting block 202, a square rod 203, a mounting block 204 and a stop block 205.

[0033] By adopting a two-stage arc design, the arc gradually increases closer to the two sides of the dental wedge, and the larger the arc, the more suitable it is for a large gap. Therefore, the dental wedge can better fit the shape of the adjacent surfaces of the teeth, so that it can be stuck between two teeth.

[0034] like Figure 1 and Figure 4 As shown, the punching block 201 is movably installed inside the threading hole 106 , and the connecting block 202 is fixedly connected to the punching block 201 .

[0035] The perforated block 201 can provide a fulcrum for the dental wedge body 1, thereby facilitating the support of the dental wedge body 1 and picking up the dental wedge body 1, while the connecting block 202 can contact the handle area 104, and the movement of the connecting block 202 can push the handle area 104, thereby facilitating the caregiver to squeeze the handle area 104.

[0036] like Figure 5 As shown, the square rod 203 is movably assembled inside the connecting block 202 , the stopper 205 is fixedly connected to one end of the square rod 203 close to the connecting block 202 , and the mounting block 204 is fixedly connected to one end of the square rod 203 away from the connecting block 202 .

[0037] The square rod 203 can have a limiting effect and can also apply sufficient force to the forming sheet through the rebound force, so that the connecting block 202 and the mounting block 204 can only move towards each other. When the connecting block 202 and the mounting block 204 move towards each other, the two handle areas 104 can be squeezed, so that the wedge body 101 is deformed and the two sides are close to each other.

[0038] like Figure 4 As shown, a slot hole 3 is provided inside the mounting block 204 , and the diameter of the slot hole 3 is larger than the diameter of the perforated block 201 .

[0039] The perforating block 201 can pass through the interior of the mounting block 204 through the slot 3, so when the connecting block 202 and the mounting block 204 move toward each other and press the wedge body 101, the perforating block 201 will not interfere with the approach of the connecting block 202 and the mounting block 204.

[0040] like Figure 4 As shown, a support block 401 is fixedly connected to the connection block 202 , and a support rod 402 is fixedly connected to the support block 401 .

[0041] The support block 401 can be used to fix the support rod 402, and the support rod 402 can be stuck in the arc groove 105 after the punching block 201 enters the threading hole 106, so that the dental wedge body 1 can be stably supported as a whole through cooperation with the punching block 201, making it convenient to take the dental wedge body 1.

[0042] like Figure 4 As shown, the connecting block 202 and the mounting block 204 are both fixedly connected with an annular block 501 , which is mounted on the side of the connecting block 202 opposite to the mounting block 204 . There are two annular blocks 501 , which are exactly the same.

[0043] The annular block 501 can prevent the connecting block 202 and the mounting block 204 from completely fitting together, so that the connecting block 202 and the mounting block 204 cannot completely press the two sides of the wedge body 101 to fit together, so that the wedge body 101 will not be unable to recover due to plastic deformation.

[0044] like Figure 5As shown, a compressed telescopic spring 502 is fixedly mounted between the connecting block 202 and the mounting block 204 , and two ends of the telescopic spring 502 are respectively located inside the two circular ring blocks 501 .

[0045] The telescopic spring 502 can push the connecting block 202 and the mounting block 204 so that the distance between the connecting block 202 and the mounting block 204 is kept at a maximum, thereby facilitating the installation of the taking assembly 2 on the dental wedge body 1 .

[0046] like Figure 1 As shown, the wedge body 101, the second wedge section 102 and the handle area 104 are made of memory metal, and the soft pad 103 is made of silicone.

[0047] Due to the characteristics of memory metal, when the wedge body 101 is squeezed so that its two sides are close to each other, a repulsive force will be generated inside the wedge body 101, so that the wedge body 101 can be restored when the squeezing is lost, so that the wedge body 101 has rebound performance.

[0048] like Figure 1 As shown, the wedge body 101 and the second-section wedge body 102 both have curvatures, and the curvature of the second-section wedge body 102 is greater than that of the wedge body 101 .

[0049] Through the curvature design of the wedge body 101 and the second wedge body 102, the wedge body 101 and the second wedge body 102 can fit the shape of the adjacent surfaces of the teeth, and the second wedge body 102 can fit the tooth neck more closely.

[0050] like Figure 1 As shown, there are two threading holes 106 , and the two threading holes 106 are the same in size and shape, and the threading holes 106 are circular in shape.

[0051] Through the design of the threading hole 106, the dental floss can pass through the inside of the threading hole 106, and the dental floss can be fixed on the teeth, so it can prevent the dental wedge body 1 from accidentally falling out of the mouth, thereby preventing accidental swallowing.

[0052] According to the working principle of the utility model, the nursing staff first passes the punching block 201 through the inside of the threading hole 106 on one side, so that the handle area 104 is located between the connecting block 202 and the mounting block 204, and moves the support rod 402 to the position of the arc groove 105, so as to pick up the dental wedge body 1, and press the connecting block 202 and the mounting block 204, so that the connecting block 202 and the mounting block 204 are close to each other, so that the two sides of the wedge body 101 are close to each other, and then the nursing staff can insert the wedge body 101 between the two teeth, and loosen the connecting block 202 and the mounting block 204, at which time the wedge body 101 will rebound and get stuck between the two teeth, and the telescopic spring 502 rebounds so that the distance between the connecting block 202 and the mounting block 204 returns to the maximum, and the nursing staff can fill the tooth proximal cavity after removing the picking component 2.

[0053] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
