[0002] After the cementation of all-ceramic crown, metal-ceramic crown, all-metal bridge and other fixed denture prosthetic repair, the cement (cement, resin-based adhesive, etc.) often forms fine residues at the gum margin, gingival sulcus and below the alveolar ridge. These residual cements become local chronic irritants, which can induce gingivitis, periodontitis, and alveolar ridge mucositis. If not cleaned in time, long-term inflammation can lead to bone resorption, tooth loosening, and prosthetic body shedding, and even the need for re-prosthetic repair.

[0003] After the cementation process, excess cement often spills from the edge of the prosthetic body, especially below the gum margin.

Detailed Implementation

[0041] Example 1

[0042] The following is combined with Figures 1-2 Example 1 will be described in detail.

[0043] A cleaning unit 10 for removing excess cement is provided. The cleaning unit 10 includes a cleaning part 101 with a hollow annular hole structure. The cross-section of the hollow annular hole matches the cross-section of the tooth. The cleaning part 101 can fit into the narrow gap between the bridge tissue surface and the gingiva to effectively remove excess cement with linear edges.

[0044] The cleaning unit 10 also includes an operating structure 102. The cleaning unit 101 and the operating structure 102 are integrally made of an elastic material. The elastic material allows the cleaning unit 10 to deform when it comes into contact with the gums and oral soft tissues, avoiding scratches or punctures that may be caused by rigid instruments. This flexible contact can significantly reduce the risk of trauma to fragile gums and improve the safety of treatment.

[0045] Preferably, the elastic material is elastic nylon.

[0046] The operating structure 102 is an ear wing designed on both sides of the cleaning unit 101 for easy gripping with both hands. This design allows doctors to hold the device stably with both hands during operation, which is especially suitable for scenarios requiring precise control of force. Alternatively, the operating structure 102 is a finger ring designed on one side of the cleaning unit 101 for easy one-handed operation. This design allows doctors to conveniently operate the cleaning unit 10 with one hand during operation, which is especially suitable for scenarios requiring rapid operation or one-handed operation.

[0047] In this embodiment, the hollow annular hole is provided with burrs (not shown in the figure), micropores, or rough surfaces that can carry away the adhesive when rubbing against the teeth. This design can enhance the friction between the cleaning unit 10 and the teeth, ensuring that the adhesive is more effectively carried away and removed during the cleaning process, thereby improving the cleaning effect.

[0048] The cleaning unit 10 for removing excess cement provided in this embodiment operates as follows: The dentist first places the cleaning unit 10 onto the tooth or bridge to be cleaned, and then uses the thumbs and forefingers of both hands to pinch the two sides of the loop, making it form a long U-shape below the bridge tissue surface. Appropriate tension is applied, and the dentist can perform a horizontal sawing motion: repeatedly pulling along the left and right direction of the bridge to cut and remove the linear cement, or a vertical lifting motion: gently lifting the cleaning unit 10 towards the gum line to ensure that any residue in the gingival sulcus is removed. The cleaning unit 10, made of elastic material, allows it to fit tightly against the bridge and tooth surface, achieving seamless cleaning. After cleaning, the cement-coated loop is removed from the mouth, and a routine inspection of the restoration margins is performed to confirm that the excess cement has been completely removed.

[0049] Example 2

[0050] The following is combined with Figures 3-4 Example 2 will be described in detail.

[0051] A cleaning unit assembly 20 capable of removing excess adhesive includes a strip body 201 formed by connecting multiple cleaning units 10 as described in the foregoing embodiments. The cleaning unit assembly 20 also includes a mandrel 202, with the strip body 201 wound around the mandrel 202. Adjacent cleaning units 10 are provided with separation portions 30, which extend along the width direction of the cleaning unit 10 or have guide portions 40 on both sides. The guide portions 40 are provided with perforations along the width direction of the cleaning unit 10. The guide portions 40 can provide an external force application point to assist the cleaning unit 10 in separating along the separation portion 30, enabling doctors to apply force precisely and avoid uneven tearing caused by improper force application, thus preventing material waste caused by incomplete tearing of the cleaning unit 10.

[0052] Furthermore, the separation section 30 is a tear-resistant or pre-tear line set on the surface of the strip body 201, which reduces the external force required for tearing, making the separation operation more labor-saving and convenient, reducing the burden on the doctor's hands, improving work efficiency, and at the same time, the force applied during the tearing process is stable, and it is not easy for material to break or tear unevenly due to uneven force application.

[0053] Specifically, the guide part 40 has a concave structure. The cleaning unit group 20 uses the guide part 40 and the separation part 30 to cooperate with each other. The concave structure of the guide part 40 can provide physical positioning for the doctor's finger, preventing the force application point from deviating from the separation part 30. The guide part 40 can also enhance the stress concentration effect of the separation part 30. When external force is applied through the guide part 40, the stress will quickly converge on the weakened structure of the separation part 30, causing the separation part 30 to break along a preset path, reducing the external force threshold required for tearing, and achieving labor-saving separation.

[0054] In this embodiment, the annular holes of the cleaning unit 10 can be formed on its left and right sides. In other embodiments, the annular holes can be formed on its top and bottom sides. Specifically, in this embodiment, the annular holes of the cleaning unit 10 can be provided on the left and right sides of the cleaning unit 10. When in use, the doctor can flip the cleaning unit 10 as needed to match the tooth arrangement to be cleaned, thus cleaning excess oral adhesive.

[0055] The working principle of the cleaning unit assembly 20 for removing excess adhesive provided in this embodiment is as follows:

[0056] First, based on the extent to which excess cement needs to be cleaned inside the patient's mouth, determine the number of cleaning units 10 to be separated and the corresponding location of the separation part 30. The doctor can then separate the required cleaning units 10 through the separation part 30. After that, the doctor will put the cleaning units 10 on the teeth or aprons and clean the teeth or aprons to be cleaned according to the aforementioned cleaning method.

[0057] Example 3

[0058] like Figure 5 As shown, unlike Embodiment 2, the annular holes of the cleaning unit 10 are located on its upper and lower sides. During use, the dentist can adapt the cleaning unit group 20 provided in Embodiment 2 or the cleaning unit group 20 provided in this embodiment to better suit the cleaning needs of teeth in different locations, depending on the specific arrangement of the teeth to be cleaned. This design further enhances the versatility and practicality of the cleaning unit group 20, enabling precise cleaning of both upper and lower teeth, and both anterior and posterior teeth, through a simple flipping operation.

[0059] Example 4

[0060] The following is combined with Figures 6-11 Example 4 will be described in detail.

[0061] An adhesive removal kit includes a box body 50, which houses a cleaning unit assembly 20 for removing excess adhesive as described above. The box body 50 has a storage cavity 501, within which a mounting mechanism 70 is provided that matches the spindle 202 of the cleaning unit assembly 20. This design allows the cleaning unit assembly 20 to be securely installed within the box body 50, facilitating storage and retrieval. In this embodiment, the mounting mechanism 70 is an arc-shaped mounting hole located on both side walls of the storage cavity 501, and the spindle 202 can be installed at the arc-shaped mounting hole. In other embodiments, the mounting mechanism 70 is a rotating shaft (not shown in the figure) located on both side walls of the storage cavity 501, which can be sleeved with the spindle 202 to fix the cleaning unit assembly 20.

[0062] In this embodiment, the box body 50 is hinged to the cover body 80. The cover body 80 is provided with a first fixing member 901 on the side near the storage cavity 501. A second fixing member 902 is provided in the storage cavity 501 corresponding to the first fixing member 901. The first fixing member 901 and the second fixing member 902 can cooperate to form a clamping structure. A clamping gap is provided between the clamping structures. One end of the cleaning unit group 20 can pass through the clamping gap. The clamping structure can firmly fix the cleaning unit group 20 in the storage cavity 501 to prevent the cleaning unit group 20 from shifting, tangling or scattering during transportation or carrying.

[0063] Furthermore, the first fixing member 901 is provided with a reset member (not shown in the figure). The reset member can provide a restoring force for the clamping mechanism. When the doctor presses down on the cover 80, the reset member is compressed, and the clamping mechanism can clamp the strip body 201. When the doctor releases the cover 80, the reset member returns to its original shape, and the gap between the first fixing member 901 and the second fixing member 902 increases, so that the strip body 201 can pass smoothly through the clamping gap.

[0064] The outer wall of the box 50 is provided with a cutting blade 60. The cutting blade 60 has a serrated structure and can cooperate with the separation part 30 to separate the cleaning unit group 20 into several independent cleaning units 10. The design of the cutting blade 60 and the separation part 30 allows doctors to directly complete the separation operation of the cleaning unit 10 on the box 50 without having to find additional scissors or cutting tools. This integrated design significantly improves the convenience of clinical operation. In particular, during the operation, doctors can quickly tear off the cleaning unit 10 of the required length, reduce operation steps, and improve work efficiency.

[0065] Specifically, the cutting edge 60 is made of stainless steel.

[0066] The outer wall of the box body 50 is provided with a first fastening element (not shown in the figure), and the outer wall of the cover body 80 is provided with a second fastening element (not shown in the figure). The first fastening element and the second fastening element are engaged to keep the box body 50 and the cover body 80 in a closed state, effectively preventing the cover body 80 from being opened accidentally and ensuring that the cleaning unit group 20 in the storage cavity 501 is properly protected.

[0067] The working principle of the excess adhesive preparation box provided in this embodiment is as follows:

[0068] Before operation, confirm that the first and second fastening parts of the configuration box are in the fastening state to ensure that the cleaning unit group 20 is not contaminated; apply outward force to separate the first and second fastening parts and open the cover 80; pinch the free end of the cleaning unit group 20 from the clamping structure of the storage cavity 501, and slowly pull out the required length of the cleaning unit group 20 along the winding direction of the mandrel 202, avoiding tangling or knotting of the cleaning unit group 20 during the pulling process.

[0069] If the doctor uses a manual separation method: Place the fingers of both hands on the guide portions 40 on both sides of the target separation portion 30, allowing the cleaning unit assembly 20 to precisely break along the separation portion 30, separating one or more continuous cleaning units 10. If the doctor uses an assisted separation method: Place the target separation portion 30 of the cleaning unit assembly 20 against the serrated cutting edge 60, aligning the separation portion 30 with the tips of the cutting edge 60. Hold the box body 50 with one hand and pull the cleaning unit assembly 20 with the other, using the concentrated pressure of the cutting edge 60 to separate the cleaning unit assembly 20 along the separation portion 30. After the cleaning operation is completed, close the cover 80, ensuring a secure fit between the first and second fastening components, preventing contamination of the cleaning unit assembly 20.

[0070] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
