Description

Technical Field

[0001] The utility model relates to the technical field of oral medical treatment, in particular to a gingival retraction belt. Background Art

[0002] When restoring a tooth, one of the keys to ensure the firmness of the filling is to keep the surgical area clean and dry. In clinical practice, for cavities that reach deep into the gingival margin and subgingival area, gingival retraction is required to prevent gingival sulcus fluid and gingival bleeding from contaminating the filling area and to expose the edge of the cavity as much as possible for easier filling.

[0003] Gingival retraction is to use a blunt-tipped instrument such as a photosensitive knife to gently press the gingival retraction cord into the gingival sulcus around the gingival margin. Through gentle mechanical compression, the free gingiva is displaced laterally and radicularly, exposing potential gaps and the edge of the cavity. It also has a certain compression and hemostasis effect. The gingival retraction cord commonly used in clinical practice is a braided cotton thread that can absorb part of the gingival sulcus fluid and assist in moisture isolation. Gingival retraction is most commonly used to fill wedge-shaped defects. Wedge-shaped defects are tooth defects located at the neck of the tooth, often close to the gingival margin or deep below the gingiva.

[0004] The traditional gingival retraction cord has limited effect, especially for tooth defects and cavities deep under the gums. It is often difficult to completely expose the edge of the cavity, and doctors can only trim the edge by feel. This can easily lead to two situations: one is that the filling is insufficient, resulting in incomplete filling and postoperative sensitivity; the other is that the filling exceeds the edge of the cavity, forming an overhang, which not only makes the tooth shape poorly restored, affecting comfort and function, but also irritates the gums, which may lead to gingivitis or loss of periodontal attachment. Clinically, the only way to remove the overhang is to use a high-speed mobile phone with a sharp needle to adjust the edge. This operation can easily damage the gums, causing bleeding gums, gum recession, etc. The longer the adjustment and the greater the amount of adjustment, the greater the degree of gum damage. If it is insufficiently filled, it is difficult to adjust, and if necessary, it is even necessary to remove the filling and refill. In addition, for older patients or those with gingivitis, the gums are very prone to bleeding; even with the addition of hemostatic drugs to traditional gingival cords, it is often difficult to achieve the ideal hemostatic effect, causing intraoperative contamination, increasing the difficulty of filling, and reducing the firmness of the filling; therefore, clinical treatment of such cavities often requires doctors to have a high level of technical skills, delicate operations, and time-consuming and labor-intensive procedures.

[0005] In view of this, we propose a gingival retraction band to solve the existing problem. Utility Model Content

[0006] The purpose of the utility model is to provide a gingival retraction belt to solve the problems raised in the above background technology.

[0007] To achieve the above purpose, the utility model provides the following technical solution: a gingival retraction belt, comprising a gingival retraction cord and a raw material belt, one side of the raw material belt is arranged around the outer half of the gingival retraction cord and the two are fixedly connected. The gingival retraction cord is made of a plurality of cotton threads woven together and can be bent at any angle, and the raw material belt is made of polytetrafluoroethylene and can be bent at any angle.

[0008] Preferably, the length of the gingival retraction cord is between 1 cm and 300 cm, and the cross-sectional diameter of the gingival retraction cord is less than 2 mm.

[0009] Preferably, there are a plurality of drug storage gaps between the plurality of strands of cotton thread on the gingival retraction cord.

[0010] Preferably, the length of the raw tape is the same as that of the gingival retraction cord, the closest distance between the other side surface of the raw tape and the outer peripheral surface of the gingival retraction cord is 5 mm, and the thickness of the raw tape is between 0.01 and 0.3 mm.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model uses the excellent moisture-proof and corrosion-resistant properties of polytetrafluoroethylene by adding a raw tape made of polytetrafluoroethylene to the gingival retraction cord, which can effectively isolate the leakage of gingival sulcus fluid and blood and effectively improve the moisture-proof effect. At the same time, the exposed cotton thread of the gingival retraction tape is filled downward in the gingival sulcus, achieving the physical moisture-proof effect of absorbing gingival sulcus fluid and the effect of chemical hemostasis.

[0013] 2. When in use, the utility model utilizes the structure of the gingival retraction cord and the raw tape to flip the raw tape and lay it flat on the tooth surface, so that the raw tape scoops up the flowing resin, thereby forming a smooth edge and a full filling shape; the raw tape is smoothly spread on the tooth surface to shape it, and its own strong ductility allows the size and shape to be adjusted at will during shaping. It is easy to use and does not adhere to the resin, and is easy to remove at the end of filling; this method is simple to operate, has significant results, and has low technical requirements. It is especially suitable for novice doctors and suitable for promotion.

[0014] 3. In addition to being used for filling wedge-shaped defects and dental cavities at the cervical region, the utility model can also be used for filling dental cavities in the adjacent maxillary surface that are deep to the gingival margin or below the gingiva. When in use, the gingival retraction tape is filled into the gingival sulcus at the edge of the cavity, and the raw tape is spread on the adjacent gingiva to separate the adjacent teeth. This allows the flowable resin to fully fill the adjacent gingiva, eliminate the gaps between teeth, and reduce the incidence of overhanging of the filling. Then, the forming sheet is used to fill the upper cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Figures 1 to 3 As shown, a gingival retraction belt proposed by the utility model comprises a gingival retraction cord 1 and a raw tape 2. One side of the raw tape 2 is arranged around the outer half of the gingival retraction cord 1 and the two are fixedly connected. When in use, the fixed connection method is preferably an adhesive connection or a suture connection. The gingival retraction cord 1 is made of a plurality of cotton threads woven together and can be bent at any angle. The raw tape 2 is made of polytetrafluoroethylene and can be bent at any angle. When in use, the first real-time method is as follows Figures 4 to 7As shown, the gingival retraction tape is used to fill the wedge-shaped defect 6 deep under the gum at the neck of the tooth. When using it, the end of the gingival retraction tape exposed by the gingival retraction line 1 is pressed downward into the gingival sulcus, and the raw tape 2 is laid on the gums 5 to complete the moisture isolation (use process one); when filling, the lower part of the wedge-shaped defect 6 is filled first, and the upper part of the wedge-shaped defect 6 is filled with flowing resin 9, and the raw tape 2 is turned over to cooperate with shaping, which can form a full and smooth appearance and avoid underfilling and overhanging (use process two). The second real-time method when using is as follows Figures 8 to 10 As shown, the gingival retraction tape is used to fill the deep subgingival cavities on the adjacent surfaces of teeth; when in use, the gingival retraction tape is laid on the gums 5 to separate the gums 5 and the adjacent teeth, and the raw tape 2 assists in shaping, which can make the adjacent areas of the teeth full and reduce the gaps between teeth.

[0033] Furthermore, the length of the gingival retraction cord 1 is between 1 cm and 300 cm, and the cross-sectional diameter of the gingival retraction cord 1 is less than 2 mm; when in use, it can be cut according to the actual length for easy use by doctors.

[0034] Furthermore, there are a plurality of drug storage gaps 3 between the plurality of cotton threads on the gingival retraction cord 1; when in use, the gingival retraction cord 1 is made into a whole gingival retraction cord 1 with the plurality of cotton threads, so that the gingival retraction cord 1 has a moisture absorption effect, and at the same time, drugs can be added in the gaps of the cotton threads to achieve a better hemostatic treatment effect.

[0035] Furthermore, the length of the raw tape 2 is the same as that of the gingival retraction cord 1, and the other side of the raw tape 2 is preferably 1.5 cm away from the outer peripheral surface of the gingival retraction cord 1; the thickness of the raw tape 2 is preferably 0.1 mm; when in use, by miniaturizing the diameter of the gingival retraction cord 1 and the width and thickness of the raw tape 2, it can be suitable for various patients and is convenient for doctors to fill and plug the lesion during medical treatment.

[0036] The working principle of the gingival retraction tape based on the first and second embodiments is as follows: first, the technical solution is used for gingival retraction during tooth filling; the method of use is as follows: cut a suitable length, the side of the gingival retraction tape exposed from the cotton thread is downward, lightly press it into the gingival sulcus with a photosensitive knife, etc., wrap the raw tape 2 with one side upward, stretch the raw tape 2 and lay it flat on the gingiva below the cavity without covering the surgical area;

[0037] The raw tape 2 can isolate gingival sulcus fluid and blood seepage, further enhancing the moisture-isolating effect;

[0038] When filling the cavity, fill the bottom and upper edge of the cavity first. When filling the part near the gingival margin, squeeze in a sufficient amount of flowing resin, then turn the raw tape 2 up to cover the tooth surface, and then flatten it. The raw tape 2 will scoop up the flowing resin along the gingival margin, and a smooth edge can be formed at the connection between the filling and the tooth without deliberate shaping, effectively preventing overhang; at the same time, the raw tape 2 will also squeeze the flowing resin when the tooth surface is flattened, naturally forming a fuller and smoother shape; then perform light curing, and after the resin hardens, turn down the raw tape 2 to expose the filling, and light cure again to ensure the curing effect; after the filling is completed, remove the gingival tape; check the edge with a probe, and adjust and grind it if necessary.

[0039] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
