Technical Problem

[0003]一般基台与口腔软组织接触,长期接触容易在基台上滋生细菌,进一步损害软组织,因此生产基台时,需对基台外壁进行抛光处理,但是,若在基台的外壁进行全局抛光,则其螺丝部分也跟随抛光,这就改变了螺丝部分的尺寸,影响螺丝部分与种植体连接的精度,降低种植体与基台连接的稳定性

Benefits of technology

上述的防菌型复合结构具有抛光层,其中抛光层位于基台的顶部和第一过渡部,以起到局部抛光的作用,而顶部和第一过渡部均与口腔软组织接触,抛光部分用于隔绝细菌,而基台与种植体之间的连接位置则不抛光,也就不影响螺纹杆的尺寸,进而保证螺纹杆的尺寸和种植体的螺纹孔的尺寸相匹配,同时,第一过渡部与第二过渡部之间形成的镀层交界区,且镀层交界区抵接于所述连接过渡孔的内壁,以使第二过渡部和口腔软组织隔绝,如此既能够有效隔绝基台在第二过渡部滋生的细菌,也保证了基台通过螺丝与种植体连接的精度。

Description

Technical Field

[0001] This disclosure relates to the field of dental implant technology, and in particular to an antibacterial composite component and an antibacterial composite structure. Background Technology

[0002] Typically, when implanting a tooth, the implant is first placed into the alveolar bone, and the implant connects to the alveolar bone via external threads on its periphery. In existing technology, the abutment has vertical screw holes, and the abutment is connected to the implant via screws. Finally, the crown is cemented onto the abutment.

[0003] Generally, the abutment comes into contact with the oral soft tissue. Long-term contact can easily lead to the growth of bacteria on the abutment, which can further damage the soft tissue. Therefore, when manufacturing the abutment, the outer wall of the abutment needs to be polished. However, if the outer wall of the abutment is polished all over, the screw part will also be polished. This changes the size of the screw part, affects the precision of the connection between the screw part and the implant, and reduces the stability of the connection between the implant and the abutment. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an antibacterial composite component and antibacterial composite structure that can isolate bacteria and ensure the accuracy of the connection between the abutment and the implant via screws.

[0005] The purpose of this disclosure is achieved through the following technical solution: An antibacterial composite structure includes an abutment, an implant, and a polishing layer. The abutment has a threaded rod, and the implant has a threaded hole. The threaded rod is located within the threaded hole, allowing the abutment to be connected to the implant via the threaded rod. The abutment has a top, a first transition portion, and a second transition portion, arranged sequentially. The threaded rod is connected to the end of the second transition portion away from the top. The maximum cross-sectional diameter of the top is greater than the maximum cross-sectional diameter of the second transition portion. The polishing layer is disposed on the top and the first transition portion. The implant also has a connecting transition hole communicating with the threaded hole. The second transition portion is located within the connecting transition hole. A plating boundary area is formed between the first transition portion and the second transition portion, and the plating boundary area abuts against the inner wall of the connecting transition hole.

[0006] In one embodiment, the antibacterial composite structure further includes a sealing ring, which is disposed around the coating junction area, and the outer wall of the sealing ring abuts against the inner wall of the connection transition hole to seal the connection transition hole.

[0007] In one embodiment, the sealing ring is a silicone ring.

[0008] In one embodiment, the axial length of the top is less than the axial length of the first transition portion.

[0009] In one embodiment, the axial length of the top is less than the axial length of the second transition portion.

[0010] In one embodiment, the maximum cross-sectional diameter of the top is 5-6 mm.

[0011] In one embodiment, the diameter of the connecting transition hole is larger than the diameter of the threaded hole.

[0012] In one embodiment, the implant has an external thread.

[0013] In one embodiment, the base has a conical structure.

[0014] An antibacterial composite component includes the antibacterial composite structure described in any of the embodiments.

[0015] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned antibacterial composite structure has a polishing layer located at the top of the abutment and the first transition section for localized polishing. Both the top and the first transition section are in contact with the oral soft tissue. The polished portion is used to isolate bacteria, while the connection between the abutment and the implant is not polished, thus not affecting the size of the threaded rod. This ensures that the size of the threaded rod matches the size of the threaded hole of the implant. At the same time, the plating interface area formed between the first transition section and the second transition section abuts against the inner wall of the connecting transition hole, thus isolating the second transition section from the oral soft tissue. This effectively isolates bacteria that grow on the abutment in the second transition section and also ensures the accuracy of the connection between the abutment and the implant via screws.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figure 1 and Figure 2This is an embodiment of the antibacterial composite structure 10 of the present invention, comprising a base 100, an implant 200, and a polishing layer 300. The base 100 is provided with a threaded rod 110, and the implant 200 is provided with a threaded hole 210. The threaded rod 110 is located in the threaded hole 210 so that the base 100 is connected to the implant 200 through the threaded rod 110. The base 100 has a top 120, a first transition portion 130, and a second transition portion 140, which are arranged sequentially. The threaded rod 110 is connected to the first transition portion 120, the first transition portion 130, and the second transition portion 140. The second transition portion 140 is located away from the top 120. The maximum cross-sectional diameter of the top 120 is greater than the maximum cross-sectional diameter of the second transition portion 140. The polishing layer 300 is disposed on the top 120 and the first transition portion 130. The implant 200 is also provided with a connecting transition hole 220, which communicates with the threaded hole 210. The second transition portion 140 is located inside the connecting transition hole 220. A plating boundary area 150 is formed between the first transition portion 130 and the second transition portion 140. The plating boundary area 150 abuts against the inner wall of the connecting transition hole 220.

[0023] It can be understood that the polishing layer 300 is provided on the top 120 and the first transition portion 130, that is, the position where the base 100 contacts the oral soft tissue is polished, so as to make the surface of the top 120 and the first transition portion 130 smooth, thereby isolating bacteria that grow in contact with the oral soft tissue. The second transition portion 140 and the threaded rod 110 do not contact the oral soft tissue, and thus do not change the size of the threaded rod 110.

[0024] In the above embodiments, the antibacterial composite structure 10 has a polishing layer 300, which is located at the top 120 and the first transition portion 130 of the abutment 100 to perform local polishing. Both the top 120 and the first transition portion 130 are in contact with the oral soft tissue. The polished portion is used to isolate bacteria, while the connection position between the abutment 100 and the implant 200 is not polished, so it does not affect the size of the threaded rod 110. This ensures that the size of the threaded rod 110 matches the size of the threaded hole 210 of the implant 200. At the same time, the plating boundary area 150 formed between the first transition portion 130 and the second transition portion 140 abuts against the inner wall of the connecting transition hole 220, so that the second transition portion 140 is isolated from the oral soft tissue. This can effectively isolate bacteria growing in the second transition portion 140 of the abutment 100 and also ensure the accuracy of the connection between the abutment 100 and the implant 200 by screws.

[0025] like Figure 1 and Figure 3As shown, in one embodiment, the antibacterial composite structure 10 further includes a sealing ring 400, which surrounds the plating interface area 150. The outer wall of the sealing ring 400 abuts against the inner wall of the connection transition hole 220 to seal the connection transition hole 220, thereby binding the second transition portion 140 of the base 100 to the soft tissue and preventing bacteria from growing in the second transition portion 140. Further, the sealing ring 400 is a silicone ring, so that the sealing ring 400 has certain deformation characteristics to effectively seal the connection transition hole 220.

[0026] like Figure 1 As shown, in one embodiment, the axial length of the top 120 is less than the axial length of the first transition portion 130.

[0027] like Figure 1 As shown, in one embodiment, the axial length of the top 120 is less than the axial length of the second transition portion 140.

[0028] In one embodiment, the maximum cross-sectional diameter of the top 120 is 5-6 mm. In this embodiment, the maximum cross-sectional diameter of the top 120 is 5 mm.

[0029] like Figure 1 As shown, in one embodiment, the diameter of the connecting transition hole 220 is larger than the diameter of the threaded hole 210, so that the plating interface area 150 formed between the first transition portion 130 and the second transition portion 140 can abut against the inner wall of the connecting transition hole 220.

[0030] like Figure 1 As shown, in one embodiment, the implant 200 has an external thread 230 so that the implant 200 is inserted into the alveolar bone in a threaded manner.

[0031] like Figure 1 , Figure 2 or Figure 3 As shown, in one embodiment, the base 100 has a conical structure so that the base 100 is effectively mounted on the hollow part of the soft tissue, wherein the threaded rod 110 is located at the top of the cone.

[0032] This disclosure also provides an antibacterial composite component, including the antibacterial composite structure 10 described in any embodiment.

[0033] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned antibacterial composite structure 10 has a polishing layer 300, which is located at the top 120 and the first transition portion 130 of the abutment 100 to provide local polishing. Both the top 120 and the first transition portion 130 are in contact with the oral soft tissue. The polished portion is used to isolate bacteria, while the connection position between the abutment 100 and the implant 200 is not polished, thus not affecting the size of the threaded rod 110. This ensures that the size of the threaded rod 110 matches the size of the threaded hole 210 of the implant 200. At the same time, the plating boundary area 150 formed between the first transition portion 130 and the second transition portion 140 abuts against the inner wall of the connecting transition hole 220, thereby isolating the second transition portion 140 from the oral soft tissue. This effectively isolates bacteria that grow on the abutment 100 in the second transition portion 140 and also ensures the accuracy of the connection between the abutment 100 and the implant 200 via screws.

[0034] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
