Description

Technical Field

[0001] This invention relates to the field of oral medical devices, and more particularly to a rubber dam for the alveolar bone (also known as the alveolar bone, which refers to the area where the tooth root is inlaid at the lower edge of the maxilla and the upper edge of the mandible). Background Technology

[0002] In various dental treatment scenarios, instruments are frequently used to perform operations such as grinding, drilling, and cleaning teeth within the oral cavity. This generates a significant amount of waste and cleaning water. The retention of this waste and cleaning water in the oral cavity can cause discomfort to the patient and contaminate the surgical area. Therefore, a rubber dam is typically used to assist in treatment. The rubber dam primarily serves to isolate the surgical area, prevent dental instruments from falling into the mouth and being swallowed into the abdomen or trachea, and prevent secondary infections from saliva and bacteria. Correct use of the rubber dam can significantly improve treatment efficiency and patient comfort, and reduce iatrogenic injury.

[0003] A rubber dam typically consists of a rubber dam sheet and a support structure. The rubber dam sheet provides isolation, while the support structure supports the dam, maintains its tension, and preserves the surgical area for the surgeon's convenience. The rubber dam sheet is usually made of an elastic material; the support structure is typically made of metal or plastic. Common rubber dam supports are U-shaped and circular. U-shaped supports are used for small-area treatments, while circular supports are more widely used for isolation treatments involving the entire dental arch (also known as the dentition, where the teeth of the upper and lower jaws are arranged continuously in a parabolic arc shape in the alveolar bone).

[0004] The existing rubber dam technology typically involves the following steps in practical use: (i) placing the rubber dam inside the patient's mouth; (ii) adjusting the rubber dam to determine the drilling positions; (iii) using a rubber dam punch to drill holes in the rubber dam that match the teeth, and then using dental floss or other auxiliary tools to slip the rubber dam into place, exposing the teeth; (iv) using rubber dam clips or other auxiliary tools to fix and support the rubber dam, facilitating the dentist's operation. The existing rubber dam technology is cumbersome and time-consuming to use, and requires numerous auxiliary tools, making it unsuitable for various dental specialties. Summary of the Invention

[0005] The purpose of this invention is to provide a rubber dam for the alveolar process, which has a simple structure, is easy to operate, facilitates treatment, and has wide applicability.

[0006] To achieve the above objectives, the present invention provides a rubber dam for the alveolar process, comprising a rubber dam cloth and an outer support and an inner support disposed on the rubber dam cloth. The rubber dam cloth, the outer support, and the inner support are all made of elastic material. The outer support is an elastic ring. The inner support is located inside the outer support and includes an outer ring, an inner ring, and two pairs of connecting parts connecting the inner ring and the outer ring. Each pair of connecting parts, together with the outer ring and the inner ring, forms a closed ring. The closed ring is used to fix the rubber dam cloth to the alveolar process. The rubber dam cloth forms an opening area within the closed ring.

[0007] The opening area is provided with an annular perforation line, which is used to make an opening along the annular perforation line during treatment to expose the area to be treated.

[0008] The opening area has an opening to expose the area to be treated during treatment.

[0009] The opening is arc-shaped.

[0010] The rubber barrier is made of SEBS (Styrene-Ethylene-Butylene-Styrene) thermoplastic elastic rubber.

[0011] The external support is made of polypropylene (PP) elastic material.

[0012] The internal support is made of polypropylene (PP) elastic material.

[0013] The outer support is positioned at the edge of the rubber barrier.

[0014] Each connecting part includes a first reinforcing part disposed on the outer ring, a second reinforcing part disposed on the inner ring, and a third reinforcing part respectively connected to one end of the first reinforcing part and the second reinforcing part, thus forming a horseshoe shape; the horseshoe-shaped openings of each pair of connecting parts are opposite to each other.

[0015] The first reinforcing part extends at one end away from the third reinforcing part in a direction away from the inner ring to form a handhold. When in use, pressure is applied to the handhold, and the connecting part applies the pressure received by the handhold to both the outer ring and the inner ring at the same time, thereby achieving synchronous deformation of the outer ring and the inner ring to facilitate the removal, wearing, or adjustment of the rubber barrier.

[0016] The rubber barrier is bonded together with the inner and outer supports to form a single unit.

[0017] The rubber barrier also includes a first cavity for accommodating the outer support and a second cavity for accommodating the inner support. The outer support is enclosed in the first cavity by the rubber barrier, and the inner support is enclosed in the second cavity by the rubber barrier.

[0018] The beneficial effects of this invention are as follows: The rubber dam, outer support, and inner support of the alveolar dam of this invention are all made of elastic materials, which are elastic and can adapt to the oral cavity shape of different patients. After being placed in the oral cavity, the elastic force adapts to the deformation of the oral cavity and forms a waterproof seal on the alveolar mucosa. The outer ring, inner ring, and connecting part of the inner support form a closed ring for fixing the rubber dam to the alveolar ridge, placing the entire dentition in the opening area and sealing the mucosa, tongue, palate, and pharynx, which facilitates the doctor's operation on the teeth, gums, and alveolar bone. The alveolar dam of this invention utilizes the elasticity of the closed ring formed by the outer ring, inner ring, and connecting part to adapt to the shape and size of the dental arch of different patients, making it easy to put on, take off, adjust, and fix the rubber dam. The operation is simple and quick, saves time, is beneficial to treatment, and has wide applicability. Attached Figure Description

[0024] Figure 5 This is a schematic diagram of another embodiment of the alveolar rubber barrier of the present invention. Detailed Implementation

[0025] To further illustrate the technical means and effects of the present invention, the following detailed description is provided in conjunction with the preferred embodiments of the present invention and their accompanying drawings.

[0026] Figure 1-3 A preferred embodiment of the present invention is shown. See also... Figure 1-3This invention provides a rubber dam for alveolar processes, comprising a rubber dam 1 and an outer support 2 and an inner support 3 disposed on the rubber dam 1. The rubber dam 1, the outer support 2, and the inner support 3 are all made of elastic material. The outer support 2 is an elastic ring disposed at the edge of the rubber dam 1. The inner support 3 is located inside the outer support 2 and includes an outer ring 31, an inner ring 32, and two pairs of connecting parts 33 connecting the inner ring 32 and the outer ring 31. Each pair of connecting parts 33, together with the outer ring 31 and the inner ring 33, forms a closed ring 34. The closed ring 34 is used to fix the rubber dam 1 to the alveolar process, and the two pairs of closed rings 34 respectively fix the rubber dam 1 to the upper and lower alveolar processes. The rubber dam 1 forms an opening area 11 within the closed ring 34.

[0027] The rubber dam 1 is located between the outer support 2 and the inner support 3 (this part is located outside the oral cavity when the rubber dam is in use), and the inner support 3 (this part is located inside the oral cavity when the rubber dam is in use) is loose and has ample capacity, which can adapt to the oral cavity shape of different patients.

[0028] The alveolar dam of this invention comprises a rubber dam cloth, an outer support, and an inner support, all made of elastic materials. These materials are flexible and adaptable to different patients' oral cavity shapes. Once inserted into the oral cavity, the elastic force adapts to oral cavity deformation, forming a waterproof seal on the alveolar mucosa. The outer ring, inner ring, and connecting portion of the inner support form a closed loop for fixing the rubber dam cloth to the alveolar ridge, placing the entire dentition in the opening area and sealing the mucosa, tongue, palate, and pharynx, facilitating manipulation of the teeth, gums, and alveolar bone by the dentist. The alveolar dam of this invention utilizes the inherent elasticity of the closed loop formed by the outer ring, inner ring, and connecting portion to adapt to different patients' dental arch shapes, enabling convenient insertion, removal, adjustment, and fixation of the dam. The operation is simple and quick, saving time and facilitating treatment, with wide applicability. When the alveolar rubber dam of the present invention is installed in the mouth, the entire dentition is located under the rubber dam in the opening area. A small hole is made by point contact with a heat carrier at the tooth position that needs to be exposed. The small hole is then pressed into the interdental space of the tooth to be treated using dental floss to expose the tooth to be treated and protect the gums. It can be applied to various scenarios with strict moisture isolation, such as root canal treatment.

[0029] The rubber dam of the alveolar ridge rubber barrier of the present invention can be pre-drilled or not pre-drilled in the opening area corresponding to the alveolar ridge region. For example, in Figure 1-3 In the illustrated embodiment, the opening area 11 is provided with an annular perforation line 111, which is used to make an opening along the annular perforation line 111 during treatment to expose the area to be treated. This embodiment can be applied to various treatment scenarios, especially those requiring exposure of the entire dentition for treatment. When exposure of the entire dentition is required for treatment, the rubber dam can be opened along the preset annular perforation line to expose the entire dentition, making the use of the rubber dam more convenient and saving operation time.

[0030] As one variation of the implementation, Figure 4 Another embodiment of the alveolar dam of the present invention is shown. In this embodiment, the opening area 11' has an opening 112' to expose the area to be treated during treatment. This embodiment is suitable for scenarios requiring exposure of the entire dentition for treatment, eliminating the need for opening procedures during use. Because the rubber dam and inner support are made of elastic materials, they are flexible, adaptable to different alveolar sizes, and can adapt to oral cavity deformations. They can also fit snugly against the alveolar surface to achieve a seal against saliva. The pre-opened opening in the rubber dam further reduces the use of auxiliary instruments, making the operation more convenient, reducing operational steps, and saving operation time.

[0031] Specifically, the opening 112' is arc-shaped, similar to the shape of a dental arch.

[0032] Preferably, the rubber barrier 1 is made of thermoplastic elastic rubber.

[0033] Preferably, the rubber barrier 1 is made of SEBS thermoplastic elastic rubber.

[0034] Preferably, the outer support 2 is made of polypropylene (PP) elastic material.

[0035] Preferably, the inner support 3 is made of polypropylene (PP) elastic material.

[0036] Preferably, the inner support 3 is integrally formed.

[0037] Preferably, each connecting portion 33 includes a first reinforcing portion 331 disposed on the outer ring 31, a second reinforcing portion 332 disposed on the inner ring 32, and a third reinforcing portion 333 respectively connected to one end of the first reinforcing portion 331 and the second reinforcing portion 332, thus forming a horseshoe shape; the horseshoe-shaped openings of each pair of connecting portions 33 are opposite to each other. The structure of the connecting portion of the present invention can provide sufficient rigidity to better transmit force between the outer ring and the inner ring. In use, by applying force to the connecting portion, the outer ring and the inner ring can be deformed synchronously, thereby making it easier to put on, take off, and adjust the rubber barrier.

[0038] Preferably, the first reinforcing part 331 extends at one end away from the third reinforcing part 333 in a direction away from the inner ring 32 to form a handhold part 3311. When in use, pressure is applied to the handhold part, and the connecting part applies the pressure received by the handhold part to the outer ring and the inner ring at the same time, thereby realizing the synchronous deformation of the outer ring and the inner ring to facilitate the putting on and taking off of the rubber barrier and adjustment.

[0039] Preferably, the rubber barrier 1 is bonded together with the inner support 3 and the outer support 2 to form an integral whole, which makes the use of the rubber barrier more convenient, reduces the number of operation steps, and saves operation time.

[0040] As one variation of the implementation, Figure 5 Another embodiment of the alveolar rubber dam of the present invention is shown. In this embodiment, the rubber dam 1'' further includes a first cavity 12'' for accommodating the outer support and a second cavity 13'' for accommodating the inner support. The outer support is enclosed in the first cavity 12'' by the rubber dam 1'', and the inner support is enclosed in the second cavity 13'' by the rubber dam 1''. This makes the use of the alveolar rubber dam more convenient, reduces operation steps, and saves operation time.

[0041] Preferably, the outer support is bonded to the first cavity 12'' and the inner support is bonded to the second cavity 13'', so that the outer support and the inner support are fused with the rubber barrier 1'' to form an integral whole, which is inseparable and can achieve good sealing and isolation.

[0042] Furthermore, the second cavity 13'' may have an opening relative to the hand-held part to allow the rubber dam 1'' to extend from the hand-held part, making it convenient for the doctor to wear or adjust the alveolar rubber dam.

[0043] In summary, the alveolar dam of this invention, including the rubber dam cloth, outer support, and inner support, is made of elastic material, possessing elasticity and adapting to different patients' oral cavity shapes. After being placed in the oral cavity, its rebound force adapts to oral cavity deformation, forming a waterproof seal on the alveolar mucosa. The outer ring, inner ring, and connecting part of the inner support form a closed loop for fixing the rubber dam cloth to the alveolar ridge. During use, the closed loop is simply placed on the patient's alveolar ridge, with the entire dentition, gingiva, and alveolar bone positioned in the opening area, facilitating manipulation of the teeth, gingiva, and alveolar bone by the dentist. The alveolar dam of this invention utilizes the inherent elasticity of the closed loop formed by the outer ring, inner ring, and connecting part to adapt to different patients' dental arch shapes, enabling convenient insertion, removal, adjustment, and fixation of the rubber dam. The operation is simple and quick, saving time, facilitating treatment, and has wide applicability.

[0044] As described above, those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts of this invention, and all such changes and modifications should fall within the protection scope of the claims of this invention.
