One type of alveolar bone bionic implant

Abstract

This utility model discloses a biomimetic alveolar bone implant, including an implant body with an abutment movably inserted therein. The top of the abutment is exposed in the oral cavity. The implant body has multiple lateral grooves extending through the bottom circumferentially. The inner wall of the upper part of the implant body has a downwardly tapering oblique groove. The bottom dimension of the abutment extends downward in a columnar shape, and the radial dimension of the abutment bottom is larger than the hollow inner diameter of the implant body. This utility model, by extending the bottom dimension of the abutment downward in a columnar shape and slightly increasing the radial dimension of the abutment bottom compared to the hollow inner diameter of the implant body, and by providing multiple lateral grooves extending through the bottom circumferentially, allows the implant body to slightly expand outward circumferentially when the abutment is inserted, filling the gaps between the abutment and the inner wall of the implant body. This further improves the bonding between the abutment and the implant body and prevents the implant body from loosening.

Description

Technical Field

[0001] This utility model relates to the field of dental implant technology, specifically to a dental implant with alveolar bone bionic design. Background Technology

[0002] Dental implants specifically refer to implants used in oral surgery. These are artificial implants inserted into the jawbone to support the superstructure of the prosthesis. Dental implants are also known as artificial tooth roots and include cylindrical and root-shaped structures. After surgical placement into the jawbone at the site of the missing tooth, the implant remains stationary and replaces the dislodged or extracted tooth root. The specific procedure involves: 1. Making an incision along the alveolar ridge crest and raising the mucoperiosteal flap; 2. Using a round bur to determine the center point, gradually enlarging the hole with a guide drill and fissure drill; 3. Using a tap to create threads on the bone wall (if necessary, using a bone chisel or bone retractor to laterally expand the bone plate); 4. Screwing the implant into the implant socket to ensure initial stability.

[0003] Due to its design structure, dental implants have a relatively limited degree of integration with the bone, resulting in low initial stability and bone integration performance. This often leads to a certain degree of pain or discomfort. Furthermore, insufficient integration between the alveolar bone and the implant can easily cause the implant to loosen, reducing its stability and causing various adverse consequences.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a biomimetic alveolar bone implant that solves the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a biomimetic implant for alveolar bone, including an implant body with an abutment movably inserted therein, the top of the abutment being exposed in the oral cavity, the implant body having multiple lateral through-grooves extending through the bottom circumferentially, and the inner wall of the upper part of the implant body having a slanted groove with a gradually decreasing radial dimension. The bottom dimension of the abutment extends downward in a columnar shape, and the radial dimension of the bottom of the abutment is greater than the inner diameter of the hollow implant body.

[0009] Preferably, the implant body has a hollow interior and multiple cavities are provided along its circumferential side edges.

[0010] Preferably, the implant is made entirely of pure titanium or titanium alloy.

[0011] Preferably, an internal chamber is formed within the columnar extension at the bottom of the base, and multiple side passages are provided at one corresponding side passage, and anti-inflammatory and antibacterial drugs can be pre-sealed into the internal chamber.

[0012] (III) Beneficial Effects

[0013] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] This invention relates to a biomimetic alveolar bone implant, in which the bottom dimension of the abutment extends downward in a columnar shape, and the radial dimension of the bottom of the abutment is slightly larger than the inner diameter of the hollow implant body. At the same time, the implant body has multiple side grooves that penetrate the bottom circumferentially, so that when the abutment is inserted, the implant body is slightly expanded outward circumferentially to fill the gaps with the inner wall of the implant body, further improving the bonding between the abutment and the implant body and preventing the implant body from loosening.

[0015] This invention relates to a biomimetic alveolar bone implant, which forms an internal chamber within a columnar extension at the bottom of the abutment. Multiple side channels are provided at a corresponding side channel, allowing alveolar bone to enter the abutment through the implant body, thereby further ensuring a tighter connection between the abutment and the implant body within the alveolar bone. Furthermore, the internal chamber can be pre-sealed with anti-inflammatory, antibacterial, or bone-growth-promoting drugs. Initially, the drugs in the internal chamber are released through the side channels, while later, the patient's own bone can grow into the shell. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-2 As shown: A dental implant with alveolar bone bionic design includes an implant body 1 and an abutment 2 that is movably inserted. The abutment 2 serves as an intermediate component connecting the implant to the superstructure (crown, bridge, or denture). Specifically, it is fixed by being threaded into the implant body 1 (an internal thread 4 may be provided on the inner wall of the top of the implant body 1), and a portion of the top is exposed in the oral cavity.

[0021] The implant body 1 has a hollow interior and multiple cavities 6 are opened along the circumferential side, forming a space that communicates with the alveolar bone, allowing the alveolar bone to grow into the implant cavity 6.

[0022] The upper inner wall of the implant body 1 has a downwardly tapering oblique groove 8. Correspondingly, the bottom dimension of the abutment 2 extends downward in a columnar shape, and the radial dimension of the bottom of the abutment 2 is slightly larger than the inner diameter of the hollow implant body. Furthermore, the implant body 1 has multiple circumferentially penetrating side grooves 5, which cause the implant body 1 to slightly expand outward in the circumferential direction when inserted into the abutment 2 to fill the gaps with the inner wall of the implant body 1, further improving the bonding between the abutment 2 and the implant body 1 and preventing the implant body 1 from loosening.

[0023] The opening of multiple side grooves 5 penetrating the bottom of the implant body 1 gives it an outward expansion deformation force, and the implant body as a whole is made of pure titanium or titanium alloy.

[0024] Furthermore, an internal chamber 7 is formed within the columnar extension at the bottom of the abutment 2, and multiple side passages 9 are provided at the corresponding side passage 1 5, so that the alveolar bone can also enter the abutment 2 through the implant body 1, so as to make the abutment 2 and the implant body more closely connected in the alveolar bone.

[0025] Secondly, the built-in chamber 7 can be pre-sealed with anti-inflammatory and antibacterial drugs or drugs that help bone growth. In the early stage, the drugs in the built-in chamber 7 can be released through the side passage 2 9, and in the later stage, the patient's own bones can grow into the shell.

[0026] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
