Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a dental matrix band retainer and a matrix band. Background Art

[0002] Dental caries is the most common oral disease, and its treatment method requires strict filling with composite resin materials. When dental caries involves multiple tooth surfaces, a matrix band needs to be used as a temporary wall to prevent the filling material from overflowing from the interdental space to form a protrusion, so as to restore the normal adjacent tooth contact relationship. Refer to Figure 1 As shown, CN218922821U discloses a dental matrix band retainer, which includes an adjusting rod, a clamping member and a matrix band body. A first limiting plate is arranged on one side of the adjusting rod, a second buffer spring (the buffer spring can be replaced by a thread) is arranged on the outer side of the adjusting rod at a position on one side of the first limiting plate, a second limiting plate is arranged on the other side of the adjusting rod, a first buffer spring is arranged on one side of the second limiting plate, and a pressing block is arranged on one side of the first buffer spring. The clamping member includes a sliding ring, and elastic clamping plates are arranged at both ends of the sliding ring. Correspondingly, the end structure of the above clamping member is as Figure 2 shown, and the tooth-shaped piece structure used in CN218922821U is as Figure 3 shown. The above matrix band with a hole structure and the pliers-type matrix band retainer have the advantages of no need for auxiliary tools, convenient and fast use, high-temperature sterilization, low price, etc. However, in view of the fixed hole positions of the matrix band, and the lengths and widths of different people's different teeth are different, in the actual use process, a series of problems often occur, such as the hole positions of the matrix band are too short, the matrix band retainer is located in the middle of the diseased tooth and cannot be clamped, the hole positions of the matrix band are too long, and the matrix band retainer is far away from the adjacent surface of the diseased tooth, resulting in the matrix band not fitting well with the adjacent surface. Generally speaking, the prior art has the following defects: 1. The position of the matrix band cannot be adjusted after being fixed, the adaptability to different teeth is poor, and the restoration effect of the adjacent surface is not good; 2. The aperture of the matrix band becomes larger after use, and the matrix band and the matrix band retainer will become loose and not clamped tightly after multiple uses. Summary of the Utility Model

[0003] In view of this, the purpose of the present utility model is to provide a dental matrix band retainer and a matrix band to solve the deficiencies in the prior art.

[0004] To achieve the above purpose, the present utility model is realized by the following technical solutions:

[0005] Provided is a dental forming sheet clip, which includes an adjusting rod, a tightness adjusting plate and a clamping member connected in sequence. A U-shaped elastic splint is provided between the adjusting rod and the tightness adjusting plate. Two ends of the U-shaped elastic splint are respectively connected to a connection part between the tightness connecting plate and the clamping member. A central part of a bottom of the U-shaped elastic splint is provided with an opening and is penetrated through the adjusting rod. A pressing block is connected to the adjusting rod by a thread. Wherein, a clamping surface at an end of the clamping member has a pointed head protruding outwards, and the pointed head has a gap for clamping a forming sheet.

[0006] For the dental forming sheet clip as described above, wherein, the pointed head is a wedge-shaped head, and the gap is located in a middle part of the wedge-shaped head.

[0008] For the dental forming sheet clip as described above, wherein, the pointed head is made of silica gel.

[0009] On the other hand, provided is a forming sheet, which is applied to the dental forming sheet clip as described in any one of the above items. Wherein, the forming sheet includes a forming sheet body, and the forming sheet body does not have holes.

[0010] For the forming sheet as described above, wherein, the forming sheet body has three sizes of large, medium and small.

[0011] The beneficial effects of the technical solution of the present utility model are as follows:

[0012] The forming clamp part is improved into a pointed head such as a wedge shape, so as to increase retention. The forming sheet has better adaptability to different teeth, has little deformation after use, and is conducive to repeated disinfection and multiple uses. Description of the Drawings
