Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

Since the present invention can be subject to various changes and have various forms, specific embodiments will be illustrated in the drawings and described in detail in the text. However, this is not intended to limit the present invention to a specific disclosed form, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

1 is a diagram of a dental clamp and a dental clamp assembly including the same according to an embodiment of the present invention. Figure 2 is a diagram showing a dental clamp according to embodiments of the present invention. Figure 2 (a) is a front view of the dental clamp 100 of Figure 1, and Figure 2 (b) is a side view showing the side of the dental clamp 100. Figure 2 (c) is a side cross-sectional view of the guide part 200 of the dental clamp assembly of Figure 1, and Figure 2 (d) is a side cross-section of the guide part 300 of the dental clamp assembly of Figure 1. This is a drawing showing a cross section.

Referring to Figures 1 and 2, the dental clamp assembly may include a dental clamp 100 and guide parts 200 and 300.

The dental clamp 100 may include a body portion 110, a wing portion 120, a bow 130, a jaw (JW), and a pressing portion 112.

The body portion 110 may be formed with a tooth receiving portion (TH) so that teeth can be positioned. A tooth can be placed in the tooth receiving portion (TH) and fixed to the body portion 110 using jaws (JW) that protrude toward the tooth receiving portion (TH).

The body portion 110 may be located on a plane formed by a first direction and a second direction perpendicular to the first direction. The body portion 110 may be formed separately on both sides based on the tooth receiving portion (TH) where the tooth is located. The two separated parts may be connected to each other by the bow 130. Since the body portion 110 is formed flat on the plane, the side surface of the tooth is exposed laterally even when the dental clamp 100 is fixed to the tooth, and the tooth to be treated is visible to the therapist (doctor). The problem of the side being covered by the dental clamp 100 can be prevented.

The wing portion 120 extends from the body portion 110 and may be inclined to be inclined at a predetermined acute angle with respect to the plane formed by the first and second directions. The wings 120 are formed on both sides of the body 110, and the wings 120 are used to fix a sheet of a rubber dam or roll a cotton roll during dental treatment. It can be fixed and used to combine the guide part of the dental clamp assembly described later.

A first hole H1 may be formed in the body portion 110 and the wing portion 120. The first hole (H1) includes a first part (H1a) formed through the body part and a second part (H1b) connected to the first part (H1a) and extending to the wing part 120. can do. The first part H1a may have a first width, and the second part H1b may have a second width smaller than the first width.

A second hole H2 may be formed in the body portion 110. The second hole H2 may be formed adjacent to the first portion H1a of the first hole H1.

A third hole H3 may be formed in the wing portion 120. The third hole H3 may be formed adjacent to the second portion H1b of the first hole H1.

The first hole (H1), the second hole (H2), and the third hole (H3) are formed on the outside of the jaw (JW) of the body portion 110 using forceps in the form of forceps. It can be used to spread the teeth and position them in the tooth receiving portion (TH). Specifically, after inserting the protrusions on both sides of the forceps device into the first, second or third holes on both sides of the body portion 110, the jaws (JW) are opened to insert the teeth into the tooth receiving portion (TH). After positioning, the forceps device can be removed to fix the dental clamp 100 to the tooth. Meanwhile, the first to third holes H1, H2, and H3 may be used to couple the guide parts 200 and 300.

The bow 130 is connected to both sides of the body portion 110 and extends in the third direction D3, which is a direction perpendicular to the plane formed by the first and second directions D1 and D2, and has a ring shape. You can have

The bow 130 is connected to both sides of the body portion 110, connects the two side portions 131 extending in the third direction, and connects the side portions 131 in the first direction (D1). ) may include an upper surface portion 132 extending along.

A plane formed by the upper surface portion 132 and the first and second directions D1 and D2 may form a predetermined angle. The angle may be 95 degrees to 140 degrees. That is, the side portion 131 and the upper surface portion 132 are twisted together at the point where they meet, so that the upper surface portion 132 is twisted in a direction away from the tooth receiving portion TH, and thus the upper surface portion ( One surface of 132) may form the predetermined angle with the plane.

As will be described later in FIG. 4, since the predetermined angle forms an obtuse angle, the head of the hand piece used in dental treatment does not interfere with the bow 130, and therefore the therapist (doctor) can easily use the hand piece. It is possible, and the size of the dental clamp 100 can be kept small. In particular, the upper surface portion 132 is located on the upper side of the tooth adjacent to the tooth accommodated in the tooth receiving portion (TH), and thereby provides Treatment may be easy. As a result of closely examining the way the therapist (doctor) uses the hand piece, it was confirmed that convenience of use and space can be secured when the upper surface 132 of the bow 130 is in the range of 95 degrees to 140 degrees. (see Figure 4)

Meanwhile, in the case of a conventional clamp, since the upper surface of the bow is parallel to the plane, that is, at 0 degrees, it is not easy to treat the tooth portion close to the bow due to interference between the upper surface of the bow and the hand piece. It is possible to solve this problem by lowering the height of the bow, but in this case, it is inefficient because clamps of various sizes with bows of various heights must be used depending on the size (height) of the patient's teeth.

The jaws (JW) are protrudingly formed to fix the teeth to the tooth receiving portion (TH) of the body portion 110, and the jaws (JW) contact four places around the circumference of the teeth. It may be formed to be fixed, but is not limited thereto. For example, the jaws (JW) may be formed with more than four protrusions and may contact the teeth at more than four points. According to another embodiment, a silicone member, etc. may be bonded to the jaws (JW). , the material of the body portion 110 does not directly contact the teeth, and a silicone member, etc. can be positioned between the teeth and the body portion.

A pressing portion 112 may be further formed on the body portion 110. The pressing portion 112 may serve to press a rubber dam sheet (not shown) when using the dental clamp 100, and its end may have an arc shape.

The dental clamp 100 can be manufactured by press forming a stainless steel metal plate or by bending it after press forming, but the manufacturing method of the dental clamp 100 is not limited. For example, the dental clamp 100 can be manufactured through methods such as casting or injection. Meanwhile, when the dental clamp 100 is manufactured by bending a metal plate, there is an advantage that it can be manufactured at a low cost. The guide portion 200 is coupled to the wing 120 portion of the dental clamp 100 and may serve to secure treatment space by pressing the patient's tongue or cheek flesh. The guide portion 200 may include a coupling portion 210 and a guide wing 220 extending from the coupling portion 210. The coupling part 210 and the guide wing 220 form a predetermined obtuse angle, and accordingly, the wing part 220 can secure treatment space by pressing the patient's tongue or cheek flesh.

Coupling grooves 212 and 312 may be formed in the coupling portions 210 and 310 of the guide portions 200 and 300. A coupling protrusion (PT) is formed inside the coupling grooves 212 and 312, and when the coupling portions 210 and 310 are coupled to the body portion 110 and the wing portion 120, the coupling projection (PT) ), the engaging protrusion (PT) is received in the first hole (H1), the second hole (H2), or the third hole (H3) and the guide portions 200, 300 are moved to the dental office. It can be detachably coupled and fixed to the clamp 100.

On the other hand, the guide part 300 may be formed of a type product whose angle is adjustable, and the coupling part 310 and the guide wing 320 can be adjusted to adjust the angle formed by the coupling part 310 and the guide wing 320. The guide blades 320 may be connected by an angle adjusting unit 315.

The guide portions 200 and 300 may be respectively coupled to one or both of the wings 120 on both sides of the dental clamp 110 so that the therapist (doctor) can easily perform treatment, and the angle The adjustable guide unit 300 or the general guide unit 200 can be appropriately selected and used. In addition, the guide parts (200, 300) are prepared with guide parts of various sizes in consideration of the patient's age, gender, and mouth size, and if necessary, a guide part of an appropriate size can be used by combining with the dental clamp. there is. Meanwhile, the surfaces of the dental clamp 100 and the guide parts 200 and 300 may be subjected to diffuse reflection treatment. For example, when the dental clamp 100 and the guide portions 200 and 300 are made of metal, their surfaces may be matted. Alternatively, the dental clamp 100 and the guide parts 200 and 300 may be formed of colored metal, such as green. Through this, the therapist (doctor) may not be interrupted by light reflection from the dental clamp 100 and the guide parts 200 and 300 during the process of dental treatment.

Figure 3 is a diagram showing dental clamps according to one embodiment of the present invention. Figure 3(a) is a diagram of an embodiment in which guide wings 115 are formed on both sides, and Figure 3(b) is a diagram of an embodiment in which guide wings 115 are formed on only one side.

Referring to FIG. 3(a), the dental clamp 100a may include a body portion 110, a wing portion 120, a bow 130, jaws, and guide wings 115. Since the body portion 110, the wing portion 120, the bow 130, and the jaws of the dental clamp 100a are substantially the same as the dental clamp 100 of FIG. 1, detailed description will be omitted. .

The guide vane 115 extends from the body 110 in the second direction D2. Through this, the guide wings 115 can guide teeth adjacent to teeth accommodated in the tooth receiving portion of the body portion 110. By the guide wings 115, soft parts such as the gums of the adjacent teeth can be protected, and during dental treatment, not only the teeth accommodated in the tooth receiving portion but also the teeth adjacent to the guide wings 115 can be easily protected. Treatment is possible.

Referring to FIG. 3(b), the dental clamp 100b shows an embodiment in which guide wings 115 are formed only on one side of the body 110, and the patient's condition is controlled according to the position where the guide wings 115 are formed. It can be protected by covering the tongue or cheek flesh.

Figure 4 is a diagram showing an example of use of a dental clamp and a dental clamp assembly including the same according to embodiments of the present invention.

Referring to FIG. 4(a), the dental clamp 100 is used not only as a rubber dam clamp for fixing a general rubber dam, but also as a dental clamp alone for dental treatment. The dental clamp 100 itself can be used to protect the gums around the teeth.

Referring to Figure 4(b), it shows an embodiment in which the guide parts 200 and 300 are coupled to the dental clamp 100 and used as a dental clamp assembly. After fixing the dental clamp 100 to the teeth using a pincer-type forceps device, the necessary guide parts 200 and 300 can be joined to the patient's tongue or cheek flesh side, or both sides, Accordingly, it is possible to easily secure work space and protect the patient's gums, etc.

In addition, according to the present embodiments, the upper surface portion of the bow of the dental clamp 100 (see 132 in FIG. 1) makes an obtuse angle with respect to the flat portion (see 110 in FIG. 1) and the surface parallel to the upper surface of the tooth. Since the head portion of the hand piece (HP) used by the therapist (doctor) does not get caught in the bow 130 and does not interfere with work, the overall size of the clamp can be kept small. In particular, when treating the patient's molars, treatment is easy.

In addition, according to the present embodiments, the dental clamp 100 has an inclined upper surface of the bow and has an overall small size, so the bow can be tilted in either direction toward the inside (Distal) or outside (Mesial) of the patient's mouth. You can proceed with dental treatment by positioning it. In particular, when treating the innermost molars, the bow of the clamp can be placed on the outside of the patient's mouth, that is, toward the front teeth, and the clamp can be used by attaching the clamp to the innermost molars using jaws.

Although the description has been made with reference to the above examples, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
