[0038] The following detailed description illustrates the specific implementation method:

[0039] The markings in the accompanying drawings include: base body 1, connecting section 11, wrench hole 111, threaded section 12, extension cap 2, sleeve part 21, heightening part 22, vertical channel 221, rough part 3, and metal layer 4.

[0040] Example 1

[0041] like Figures 1-2 As shown, the disposable silicone implant healing abutment extension cap includes an abutment body 1 and a silicone extension cap 2. The abutment body 1 includes a threaded section 12 and a connecting section 11. The threaded section 12 is used to connect with the implant. The extension cap 2 includes a sleeve portion 21 and an extension portion 22. The sleeve portion 21 is used to completely fit over the connecting section 11 of the abutment body 1. The extension cap 2 and the abutment body 1 together form the transgingival and supragingival sections of the healing abutment. After installation in the oral cavity, the outer wall of the extension cap 2 contacts the gingival tissue.

[0042] The connecting section 11 of the base body 1 is provided with a wrench hole 111 at its end, and the extension cap 2's heightening part 22 is provided with a vertical channel 221 that communicates with the sleeve part 21, such as... Figure 4As shown, after the extension cap 2 is sleeved on the abutment body 1, the vertical channel 221 communicates with the wrench hole 111; when disassembling, the tool can be inserted into the vertical channel 221, and the tool can directly act on the wrench hole 111 on the abutment body 1, so that the abutment body 1 and the extension cap 2 are taken down together, which is beneficial to simplify the disassembly process.

[0043] In order to avoid accumulation of food residues in the vertical channel 221 during use, the sealing member or filling material can be used for sealing after the healing abutment is installed. In this embodiment, the filling material is preferably used for sealing. Specifically, the filling material can be sealed by medical water glue or resin.

[0044] The abutment body 1 is cylindrical, and the inner wall of the sleeve part 21 of the extension cap 2 is cylindrical, and the sleeve part 21 is tightly connected with the abutment body 1. Figures 2-3 As shown, the extension cap 2 has a cylindrical or circular truncated conical shape, which is beneficial to select different shapes of the extension cap 2 according to the gum condition of the patient, so that it is more suitable for the shape of the implant area of the patient's oral cavity.

[0045] The extension cap 2 is a pre-manufactured product, and the extension cap 2 has multiple models. Different heights of the extension cap 2 can be combined with the same abutment body 1 or different models of the abutment body 1 to form healing abutments with multiple heights. For example, the length of the extension cap 2 can be set to 8-12mm, and when the extension cap 2 is 10mm, the sleeve part 21 is 5mm and the height increasing part 22 is 5mm. The outer diameter of the sleeve part 21 can also be set to 4.0mm, 5.0mm, 6.0mm, and the inner diameter can be set to 3.5mm, 3.9mm, 4.9mm.

[0046] In actual use, different heights of the extension cap 2 can be set to the same inner diameter, which is used to combine with the same outer diameter of the abutment body 1 to form healing abutments with different heights. Different inner diameters of the extension cap 2 can be matched with different outer diameters of the abutment body 1, for example, the outer diameter of the abutment body 1 is 3.6mm, 4.0mm, 5.0mm, which is matched with the inner diameter of the extension cap 2 which is 3.5mm, 3.9mm, 4.9mm. Among them, the inner diameter of the extension cap 2 is reduced by 0.1mm than the outer diameter of the abutment body 1, which can make the two more closely combined by the elasticity of the extension cap 2, without any gap.

[0047] The use process of the one-time silicone implant healing abutment extension cap is as follows:

[0048] During the second-stage implant surgery, the gingival tissue is incised, and a suitable abutment body 1 is selected and installed onto the implant. Then, based on the difference between the abutment body 1 and the gingival structure, a more suitable extension cap 2 is selected and fitted onto the abutment body 1 to better fit the patient's gingival thickness and shape. After completion, the gingival tissue is sutured. Once the gingival tissue has grown and formed, the healed abutment is removed, and a fixed abutment is replaced for the installation of the crown. During disassembly, the filling material in the vertical channel 221 of the extension cap 2 is removed, and a disassembly screwdriver is inserted into the vertical channel 221. The screwdriver is then inserted into the wrench hole 111 of the abutment body 1, and the abutment body 1 and extension cap 2 are removed together. The entire healed abutment can be removed by tightening the screw once, making the operation simpler and more convenient.

[0049] Example 2

[0050] The difference between this embodiment and Embodiment 1 is that, as Figure 5 As shown, the outer wall of the transgingival segment of the extension cap 2 is provided with a roughened part 3. By roughening the outer wall of the extension cap 2, it is beneficial to the attachment and growth of gingival cells.

[0051] Example 3

[0052] The difference between this embodiment and Embodiment 1 is that, as Figures 6-7 As shown, the end of the heightened portion 22 of the extension cap 2 is also provided with a metal layer 4, which has a polygonal structure. Specifically, the metal layer 4 and the extension cap 2 can be injection molded into a single unit. The metal layer 4 serves two purposes: firstly, it protects the extension cap 2 and reduces wear; secondly, its polygonal structure, such as a hexagon or octagon, facilitates disassembly by using tools like wrenches to remove the extension cap 2 and the base body 1 together.

[0053] Example 4

[0054] The difference between this embodiment and Embodiment 3 is that an anti-slip layer (not shown in the figure) is provided on the inner wall of the sleeve portion 21 of the extension cap 2. The anti-slip layer helps to strengthen the stability of the connection between the extension cap 2 and the base body 1, and facilitates the removal of the entire healing base together by applying the extension cap 2 during disassembly. Specifically, the anti-slip layer can be obtained by roughening the inner wall of the sleeve portion 21, or by providing anti-slip textures on the inner wall of the sleeve portion 21 to increase friction; or by providing an anti-slip coating on the inner wall of the sleeve portion 21.

[0055] The above is only an embodiment of the present application, and the present application is not limited to the field of the embodiment, and the common knowledge such as specific structures and properties in the scheme is not described in detail herein. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope claimed in the present application should be subject to the content of the claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
