Description

Technical Field

[0001] This utility model relates to the field of dental medical device technology, and in particular to a wire-type interdental wedge. Background Technology

[0002] Nowadays, dental techniques and equipment are developing rapidly, and the demand for filling treatment is increasing. Currently, in dental clinical practice, doctors use a tool called an interdental wedge to be inserted into the interdental space for fixation and support to perform the filling.

[0003] The size and shape of interdental spaces (i.e., extragingival space) vary considerably among different affected teeth and in different positions, so interdental wedges of various sizes and shapes have been designed. Most existing interdental wedges are wedge-shaped, with one end larger than the other, making them easy to insert into the interdental space. However, these wedges only ensure close contact on the buccal and lingual sides, leaving gaps on the other side and failing to completely fill the space, leading to overhangs or complications after fillings. Furthermore, interdental wedges used clinically are mostly made of wood or hard plastic. Even with various sizes and shapes, their conformity to the diverse interdental spaces varies considerably, requiring dentists to repeatedly test or trim the wedges to fit the space, resulting in time-consuming and laborious procedures. Utility Model Content

[0004] The purpose of this invention is to provide a pull-wire type interdental wedge, which makes it easier to insert the interdental wedge into the interdental space. After being pulled, it can fill the entire interdental space, making the forming piece closely contact the cavity-shaped gingival wall. It can adapt to spaces with different interdental spaces, and can fill both the buccal and lingual gingival walls, avoiding overhangs. It does not require the design of multiple sizes and has a wider range of applications.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides a wire-type interdental wedge, including an interdental wedge body and a wire. The interdental wedge body is an elastic body. A through hole is provided through the center of the interdental wedge body along its length direction. The wire is fixed in the through hole and protrudes from both ends of the interdental wedge body. The interdental wedge body includes a small end and a large end, and the size gradually increases from the small end to the large end to make the interdental wedge body wedge-shaped. At least one recessed area is provided circumferentially on the outer wall of the interdental wedge body.

[0007] Preferably, the longitudinal cross-section of the gap wedge body is an isosceles triangle.

[0008] Preferably, the longitudinal cross-section of the gap wedge body is an equilateral triangle.

[0009] Preferably, each corner of the equilateral triangle is rounded.

[0010] Preferably, there are two recessed areas, and the connection between each recessed area and the outer wall of the gap wedge body is rounded.

[0011] Preferably, the outer wall edge of the gap wedge body has a gently wavy shape from the small end to the large end.

[0012] Preferably, the tip of the small end includes a tapered portion.

[0013] Preferably, the tip of the tapered portion is rounded, and the connection between the tapered portion and the small end is also rounded.

[0014] The present invention achieves the following beneficial technical effects compared to the prior art:

[0015] This utility model provides a pull-wire interdental wedge. The wedge body is an elastic material, allowing it to deform under external force. It can adapt to interdental spaces of various sizes and protects the gingiva from damage. The pull wire is bonded within the through-hole and protrudes from both ends of the wedge body, ensuring a tight fit. When the wire is pulled, the wedge body moves with it, making it more convenient to use. The wedge shape facilitates insertion into the interdental space. Two concave areas create a gently wavy outer surface from the small end to the large end, accommodating various interdental sizes and ensuring the wedge is not too long. Furthermore, the concave areas allow for tight filling of both buccal and lingual gingival walls, providing support and fixation to prevent overhangs and complications later in fillings. When the space wedge body is pulled, the space wedge body will gradually enter the interdental space from the small end. The space wedge body will deform and shrink when it enters the interdental space. After passing through the minimum space area, it will recover and enlarge. The concave area can fill the gingival walls on both sides of the cavity, so that the molded piece fits tightly against the entire gingival wall, so that no overhang will be produced after filling, avoiding the sequelae of the later stage of filling.

[0021] This utility model provides a wire-type interdental wedge, such as Figures 1-4 As shown, the device includes a space wedge body 1 and a pull wire 2. The space wedge body 1 is an elastic body. When subjected to external force, the space wedge body 1 will deform under compression, thus adapting to interdental spaces of various sizes and protecting the gums from damage. A through hole 3 is provided through the center of the space wedge body 1 along its length. The pull wire 2 is fixed in the through hole 3 and protrudes from both ends of the space wedge body 1. The fixing method is preferably adhesive connection, so that the space wedge body 1 is tightly adhered to the pull wire 2. When the pull wire 2 is pulled, the space wedge body 1 will move with the pull wire 2, making it more convenient to use. The space wedge body 1 includes a small end 4 and a large end 5, and the size gradually increases from the small end 4 to the large end 5 to make the space wedge body 1 wedge-shaped, so that the interdental wedge can be inserted into the interdental space more easily. The outer wall of the space wedge body 1 has at least one recessed area 6 in the circumferential direction. In a preferred embodiment, there are two recessed areas 6. By setting two recessed areas 6, the outer wall edge of the interdental wedge body 1 is gently wavy from the small end 4 to the large end 5, which not only meets the needs of various sizes of interdental spaces, thus broadening its applicability, but also ensures that the interdental wedge is not too long and affects its use. In addition, the recessed area 6 can tightly fill both the buccal and lingual gingival walls, providing support and fixation for both sides of the gingival walls, avoiding overhangs and preventing complications in the later stages of filling. When the pull wire 2 is pulled, the interdental wedge body 1 will gradually enter the interdental space from the small end 4. The interdental wedge body 1 will deform and shrink under compression as it enters the interdental space, and then return to its original size after passing through the smallest interdental space area. The recessed area 6 will ensure that both the buccal and lingual gingival walls of the cavity are tightly filled, allowing the molded piece to fit tightly against the entire gingival wall, preventing overhangs after filling and avoiding complications in the later stages of filling.

[0022] In this embodiment, the longitudinal section of the space wedge body 1 is an isosceles triangle. In a preferred embodiment, the longitudinal section of the space wedge body 1 is an equilateral triangle. This makes the space wedge body 1 more compatible with the spatial shape of the interdental space, making it easier to fit the space wedge tightly into the interdental space. Furthermore, each corner of the equilateral triangle is rounded, and the connection between each recessed area 6 and the outer wall of the space wedge body 1 is also rounded, further protecting the gingiva from damage and making it easier for the space wedge body 1 to enter the interdental space.

[0023] The tip of the small end 4 of the interdental wedge body 1 includes a tapered portion 7, the tip of which is rounded, and the connection between the tapered portion 7 and the small end 4 is also rounded. By providing the tapered portion 7, the front end of the interdental wedge can more easily enter the interdental space, and the rounding of the tapered portion 7 and its connection further ensures that the gingiva is not damaged.

[0024] The pull-wire interdental wedge provided by this utility model, in practical application, during clinical cavity repair, after preparing the cavity and placing the shaping piece, easily inserts the pull wire 2 at the small end 4 of the pull-wire interdental wedge into the interdental space. Then, using tweezers or other tools, the pull wire 2 is held and pulled towards the buccal and lingual sides, allowing the conical part 7 and the small end 4 of the wedge body 1 to sequentially enter the interdental space. Subsequently, gradually tightening is applied until the shaping piece adheres tightly to the gingival wall, so that a concave area 6 on the wedge body 1 is precisely located in the middle of the bottom of the cavity. This allows both the buccal and lingual gingival walls of the cavity to be tightly filled, ensuring the shaping piece closely adheres to the entire gingival wall. This pull-wire interdental wedge makes it easier to insert the interdental wedge into the interdental space, and after traction, the wedge body 1 can tightly fill the entire interdental space, allowing the shaping piece to closely contact the gingival wall of the cavity. It can adapt to spaces with various differences in interdental spaces, can tightly fill both the buccal and lingual gingival walls, avoid overhangs, eliminates the need for multiple sizes, and has a wider range of applications.
