Description

Technical Field

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

[0002] Dental implant technology involves surgically inserting an artificial tooth root (dental implant) precisely into the alveolar bone. After a period of healing, the dental implant forms a strong osseointegration with the alveolar bone, becoming as stable as a natural tooth root. The crown installed on this foundation closely resembles a natural tooth in appearance, color, and chewing function, providing patients with a near-natural aesthetic result and strong chewing ability, greatly improving their quality of life and self-confidence.

[0003] The structure of a dental implant mainly includes the implant body, abutment, and artificial crown. During the implantation process, a corresponding hole is first drilled in the jawbone using a tool. Then, the implant body is fixed to the jawbone in a spiral manner. After the alveolar bone and implant body form a strong osseointegration and are firmly rooted in the jawbone, the abutment and artificial crown are installed, thus completing the implantation of the tooth.

[0004] While the spiral method ensures fixation between the dental implant and the alveolar bone, the healing process between the implant and bone takes time. Therefore, the abutment is first fixed to the implant to prevent debris from entering. However, when installing the crown, the abutment needs to be replaced. During this replacement, because the connection between the abutment and the implant is also spiral, rotating the abutment can cause slight movement of the implant within the alveolar bone. This can disrupt the osseointegration between the implant and the bone, leading to implant loosening, affecting the implant's lifespan, and in severe cases, requiring reimplantation. Utility Model Content

[0005] The main purpose of this invention is to propose a dental implant that aims to solve the problem that existing dental implants are prone to slight movement within the alveolar bone when rotating the abutment.

[0006] To solve the above problems, this utility model proposes a dental implant, including a base body disposed inside the dental implant body and a guide block disposed at the bottom end of the dental implant body. The dental implant body and the base body are threadedly connected, and the dental implant body and the guide block are fixedly connected.

[0007] The dental implant body includes a first end and a vertical part, which are fixedly connected. The inner wall of the first end is provided with a threaded groove, and the inner wall of the vertical part is provided with a cylindrical groove. The threaded groove and the cylindrical groove are connected through each other.

[0008] The base body includes a smooth part and a second threaded part, which are fixedly connected.

[0009] The smooth part is slidably connected in the cylindrical groove, the second threaded part is threadedly connected to the threaded groove, the outer wall of the vertical part is provided with a first threaded part, and the first threaded part is uniformly provided with a fixing mechanism for strengthening the tight connection between the dental implant body and the dental alveolar bone.

[0010] In one embodiment, notches are uniformly provided on the first threaded portion, and the notches and the vertical portion form a vertical passage;

[0011] A first inclined portion is provided at the junction of the first threaded portion and the notch.

[0012] In one embodiment, the fixing mechanism includes a through hole and a sliding rod. The through hole is evenly distributed on the first threaded portion and passes through the entire first threaded portion and the vertical portion. The sliding rod is slidably installed on the inner wall of the through hole.

[0013] In one embodiment, one end of the sliding rod is configured as a second end that matches the outer wall of the first threaded portion, and the sliding rod is fixedly connected to the second end.

[0014] In one embodiment, the surface of the second end away from the sliding rod is provided with a rough portion.

[0015] In one embodiment, a third end is fixedly installed at the other end of the sliding rod, and the end of the third end away from the second threaded portion is set with an arc that matches the inner wall of the cylindrical groove.

[0016] In one embodiment, the third end is provided with a second inclined portion at its top end inside the cylindrical groove.

[0017] In one embodiment, the length from the second end face to the third end face is equal to the length between the inner wall of the cylindrical groove and the outer wall of the first threaded portion.

[0018] Beneficial effects: By setting a vertical passage, the technical solution of this utility model can not only reduce the contact area between the dental implant and the alveolar bone during installation, but also reduce the friction between the external threads of the dental implant and the alveolar bone during installation, thus reducing the heat generated during installation and avoiding the problem of bone cell necrosis caused by excessive temperature.

[0019] Meanwhile, the technical solution of this utility model, by setting a fixing mechanism, can increase the friction between the dental implant and the alveolar bone after the dental implant is installed. This avoids the problem of the dental implant moving slightly within the alveolar bone when rotating the abutment, which could damage the osseointegration already formed between the dental implant and the alveolar bone, causing the dental implant to loosen, affecting the lifespan of the dental implant, and in severe cases, requiring re-implantation. This reduces the risk of dental implant loosening and the possibility of re-implantation, allowing patients to use dental implants with greater peace of mind after restoration.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

If the specific posture changes, the directional indicators will also change accordingly.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0034] In this embodiment, the structure of the dental implant is as follows: Figure 1 , Figure 2 and Figure 3 As shown, where Figure 1 , Figure 2 , Figure 3 The main part shown is the part related to this utility model.

[0035] Specifically, the dental implant of this invention is constructed from a dental implant body 1, which includes a first end 11, a vertical portion 12, a first threaded portion 13, a threaded groove 15, a cylindrical groove 16, and a solid portion 19. The abutment of this invention includes a smooth portion 22 and a second threaded portion 21. Figure 2 and Figure 3In this process, the dental implant includes a base body 2 located inside the dental implant body 1 and a guide block 4 located at the bottom of the dental implant body 1. The dental implant body 1 and the base body 2 are threaded together, and the dental implant body 1 and the guide block 4 are fixedly connected.

[0036] In this embodiment, the first end 11 and the vertical part 12 of the dental implant body 1 are fixedly connected and constructed as an integral structure. The inner wall of the first end 11 is provided with a threaded groove 15, and the inner wall of the vertical part 12 is provided with a cylindrical groove 16. The threaded groove 15 and the cylindrical groove 16 are connected through each other. The smooth part 22 and the second threaded part 21 of the base body 2 are also fixedly connected as an integral structure. The smooth part 22 is slidably connected in the cylindrical groove 16, and the second threaded part 21 is threadedly connected to the threaded groove 15, thereby realizing the screw connection between the base body 2 and the dental implant body 1.

[0037] Furthermore, the outer wall of the vertical portion 12 is provided with a first threaded portion 13, and the first threaded portion 13 is uniformly provided with fixing mechanisms 3 for strengthening the tightness of the connection between the dental implant body 1 and the jawbone. For example... Figure 1 and Figure 2 As shown, the first threaded portion 13 has evenly spaced notches 14, which, together with the vertical portion 12, form a vertical passage. Compared to the continuous first threaded portion 13 in the prior art, this reduces friction between the first threaded portion 13 and the alveolar bone during implant placement, thereby reducing heat generated during installation and preventing bone cell necrosis caused by excessive temperature. This method is safer than existing methods. Furthermore, the vertical passage formed by the notches 14 and the vertical portion 12, compared to the staggered arrangement of the notches 14, better transfers heat to the outside of the alveolar bone, thus achieving better heat exchange and faster heat reduction. In addition, a first inclined portion 17 is provided at the junction of the first threaded portion 13 and the notch 14, making the first threaded portion 13 smoother during installation. Of course, the first inclined portion 17 can be designed in various ways. Figure 1 The shape can also be set to other shapes, as long as the ends have no sharp corners.

[0038] In this embodiment, as Figure 3 and Figure 4As shown, the fixing mechanism 3 includes a through hole 36 and a sliding rod 33. The through hole 36 is evenly distributed on the first threaded portion 13 and passes through the entire first threaded portion 13 and the vertical portion 12. The sliding rod 33 is slidably installed on the inner wall of the through hole 36. With this design, during the installation of the base body 2, the base body 2 presses against the sliding rod 33, causing the sliding rod 33 to slide within the through hole 36, thereby abutting against the alveolar bone and increasing the friction between the dental implant body 1 and the alveolar bone. This avoids the problem of slight movement of the dental implant body 1 when rotating the base, reduces the risk of dental implant loosening, reduces the possibility of reimplantation, and allows patients to use dental implants with more confidence after restoration.

[0039] In this embodiment, as Figure 3 and Figure 4 As shown, one end of the sliding rod 33 is configured as a second end 32 that matches the outer wall of the first threaded portion 13. The surface of the second end 32 away from the sliding rod 33 is constructed as a rough portion 31. The sliding rod 33 and the second end 32 are fixedly connected. This design allows the rough portion 31 and the outer wall of the first threaded portion 13 to form a continuous whole after the base body 2 is installed, resulting in a tighter connection between the alveolar bone and the dental implant. Furthermore, with the rough portion 31 in place, the friction between the rough portion 31 and the alveolar bone is greater when it contacts the alveolar bone due to its rough surface. This prevents the base from moving the dental implant during base rotation, reducing the risk of implant loosening and the possibility of re-implantation, allowing patients to use the implant with greater peace of mind after restoration. The rough portion 31 can consist of multiple protrusions, but the length of each protrusion is less than 0.1 mm. The rough portion 31 can also be made of specific materials.

[0040] Furthermore, in this embodiment, a third end 34 is fixedly installed on the other end of the sliding rod 33. The end of the third end 34 away from the second threaded portion 21 is set with an arc that matches the inner wall of the cylindrical groove 16. This design allows the third end 34 to abut against the second threaded portion 21 during installation, enabling the second threaded portion 21 to be installed into the cylindrical groove 16, thereby realizing the installation of the base. Moreover, after the second threaded portion 21 is installed, it can serve as a support for the third end 34, allowing the dental implant to be tightly integrated with the alveolar bone.

[0041] In this embodiment, the third end 34, located inside the cylindrical groove 16, has a second inclined portion 35 at its top. This design ensures that when the second threaded portion 21 is embedded into the inner wall of the cylindrical groove 16, the third end 34 will not obstruct the installation of the second threaded portion 21, allowing the second threaded portion 21 to smoothly enter the interior of the cylindrical groove 16. The second inclined portion 35 can be configured as follows: Figure 4The tilt angle shown can also be set to other tilt angles, as long as one side of the inclined surface is flush with the inner wall of the cylindrical groove 16 and the other side is flush with the top of the third end 34, and there are no sharp corners between the second inclined part 35 and the third end 34.

[0042] Preferably, in this embodiment, the length from the end face of the second end 32 to the end face of the third end 34 is equal to the length between the inner wall of the cylindrical groove 16 and the outer wall of the first threaded portion 13. This design ensures that after the base body 2 is installed into the dental implant body 1, the second end 32 is flush with the first threaded portion 13, so that the rough portion 31 can increase the friction between the dental implant and the alveolar bone without compressing the alveolar bone.

[0043] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
