Description

Technical Field

[0001] This utility model relates to the field of implant technology, and in particular to a dental healing abutment. Background Technology

[0002] Currently, dental healing abutments typically consist of a main body and a connecting part. The connecting part is designed in the form of a screw. This screw structure may break during installation and disassembly due to improper operation. Once a breakage occurs, repair and treatment are difficult, especially when the connecting part is prone to breakage at the connection with the main body, causing many inconveniences and risks to patients. In addition, existing healing abutments are relatively heavy, resulting in low oral comfort for the wearer. If a weight-reducing groove is added, it will not only increase the difficulty of oral cleaning, making it difficult to thoroughly remove food debris, but also affect the wearer's oral health.

[0003] In view of the above problems, this technology aims to improve the existing healing abutment structure design to solve the problem of unavoidable (occasional) fractures during operation and the weight problem of the healing abutment, and proposes a dental healing abutment. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, so that even if it breaks, the connecting part can be removed and the weight of the healing abutment can be reduced, thus providing patients with a more comfortable and convenient user experience.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dental healing abutment includes an abutment body and a connecting portion, the abutment body and the connecting portion being integrally formed. The connecting portion has an axially extending hollow channel at one end away from the abutment body, and the hollow channel passes through the connecting portion and extends into the interior of the abutment body. The hollow channel has an internal thread above the connection between the abutment body and the connecting portion. The hollow channel is used to install a breakage-resistant inner post. One end of the breakage-resistant inner post is threaded to the internal thread, and the other end is located at the opening end of the hollow channel and is fixed to the opening end by welding.

[0007] Furthermore, the cross-section of the hollow channel is circular.

[0008] Furthermore, the internal thread and the transition area between the connecting part and the base body are at the same height.

[0009] Furthermore, the anti-breakage inner column includes a column body and a welded end. The column body is provided with an external thread away from the welded end, and is threadedly connected to the internal thread through the external thread. The diameter of the welded end is the same as the diameter of the opening end of the hollow channel, and a sealed connection is formed by laser welding.

[0010] Furthermore, the pitch of the internal thread matches that of the external thread, and the thread depth is 0.1-0.3mm.

[0011] Furthermore, the outer surface of the base body is provided with a biocompatible coating, which covers the welding area at the opening end of the hollow channel, and the coating composition is hydroxyapatite or silver-containing antibacterial material.

[0012] Furthermore, the joint surface between the welded end of the anti-breakage inner column and the opening end of the hollow channel is a conical surface with a taper range of 8°-12°.

[0013] Furthermore, both ends of the column are provided with internal hexagonal slots, which are used with an internal hexagonal screwdriver to allow for forward and reverse rotation of the internal column to prevent breakage.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Anti-fracture design: By setting a hollow channel inside the connection part and installing an anti-fracture inner column in it, a double support structure for the connection part is realized. This design greatly enhances the strength of the connection part. Even if a fracture occurs under external force, the fracture point is usually located at the interface between the anti-fracture inner column and the connection part, rather than the connection between the connection part and the base body. Since the anti-fracture inner column has its own internal hexagonal groove and the other end is welded to the connection part, the fractured part (connection part) can be easily disassembled, avoiding the situation where the fracture of the existing healing base is difficult to handle.

[0016] 2. Lightweight design: The hollow channel design helps reduce the weight of the healing abutment, improving the wearer's oral comfort. At the same time, the hollow structure does not affect the mechanical properties of the healing abutment, ensuring its stability and reliability during use.

[0017] 3. Easy to clean and maintain: By using laser welding to form a sealed connection between the hollow channel opening and the anti-breakage inner column, the existing integrated design of the healing abutment is maintained. In addition, the biocompatible coating in the welding area further enhances its antibacterial properties, ensuring the patient's oral health.

[0018] In summary, the dental healing abutment provided by this utility model exhibits significant advantages in terms of fracture prevention and lightweight design without altering the original usage, providing patients with a more comfortable user experience and demonstrating practicality.

[0029] Example 1

[0030] like Figure 1-4 As shown, this embodiment provides a technical solution for a dental healing abutment: the healing abutment is mainly composed of an abutment body 1 and a connecting part 2. The two are designed to be integrally molded, which ensures the stability and reliability of the structure. A hollow channel 3 extending axially is opened at the end of the connecting part 2 away from the abutment body 1. This channel not only passes through the connecting part 2, but also extends into the interior of the abutment body 1. In the hollow channel 3, near the connection between the abutment body 1 and the connecting part 2, an internal thread 4 is provided.

[0031] The internal thread 4 is designed to install the anti-breakage inner column 5. One end of the anti-breakage inner column 5 is threaded to the internal thread 4 through the external thread on it, and the other end is located at the opening end of the hollow channel 3 and is fixed to the opening end of the hollow channel 3 by welding. This not only enhances the strength of the connecting part 2, but also allows the connecting part to be removed by disassembling the anti-breakage inner column 5 when the connecting part 2 breaks.

[0032] Example 2

[0033] Based on Example 1, this example further describes in detail the specific structure and features of the dental healing abutment:

[0034] First, the cross-section of the hollow channel 3 is designed to be circular. This design not only facilitates processing and manufacturing, but also makes it easier to install and disassemble the anti-breakage inner column 5.

[0035] Secondly, the transition area between the internal thread 4, the connecting part 2, and the base body 1 is at the same height, so that even if the connecting part 2 breaks, the anti-breakage inner column 5 is higher than the connecting part 2. At the same time, the diameter of the transition area is larger than that of the connecting part 2, which supports the opening of the internal thread 4.

[0036] The anti-breakage inner column 5 consists of a column body 501 and a welding end 502. The end of the column body 501 away from the welding end 502 is provided with an external thread 503 for threaded connection with the internal thread 4. The diameter of the welding end 502 is the same as the diameter of the opening end of the hollow channel 3. The two form a sealed connection by laser welding to ensure that the interior of the healing base is not contaminated by external factors.

[0037] The thread pitch of the internal thread 4 matches that of the external thread 503, and the thread depth is controlled between 0.1-0.3mm. This design ensures the firmness of the connection and avoids the increased processing difficulty caused by excessive thread depth.

[0038] In addition, the outer surface of the base body 1 is also provided with a biocompatible coating. This coating not only covers the entire outer surface of the base body 1, but also extends to the welding area at the opening end of the hollow channel 3. The composition of the coating can be hydroxyapatite or silver-containing antibacterial materials. This design not only improves the biocompatibility of the healing base, but also enhances its antibacterial properties.

[0039] The joint surface between the welded end 502 of the anti-breakage inner column 5 and the opening end of the hollow channel 3 is designed as a tapered surface, with the taper range controlled between 8° and 12°. This design not only facilitates positioning and fixing during welding, but also helps to improve the strength and sealing of the weld.

[0040] Finally, both ends of the column 501 are provided with internal hexagonal slots 504, which allows the anti-breakage internal column 5 to be easily rotated in both directions using an internal hexagonal screwdriver.

[0041] Workflow: When using this dental healing abutment, firstly, the anti-breakage inner post 5 needs to be threaded to the internal thread 4 in the connecting part 2 via its external thread 503. Then, the welding end 502 of the anti-breakage inner post 5 is welded and fixed to the opening end of the hollow channel 3 using a laser welding device. After these steps are completed, the healing abutment can be installed in the patient's mouth for use. If the connecting part 2 breaks during use, it can be easily repaired or replaced by disassembling the anti-breakage inner post 5.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
