Description

Technical Field

[0001] This utility model relates to the field of dental implant equipment technology, and in particular to a titanium mesh for dental implants. Background Technology

[0002] In clinical dentistry, tooth loss and jawbone atrophy create cavities. Bone and soft tissue compete to fill these cavities, but bone grows slower than soft tissue, resulting in insufficient bone around the implant. Therefore, bone grafting is often necessary. During bone grafting, bone is harvested from other sites, including bone columns and bone powder. After filling the cavity with bone columns and bone powder, they need to be wrapped and fixed to prevent them from falling out or poorly formed. Currently, titanium mesh is often used to fix the bone columns and bone powder.

[0003] Currently used titanium meshes, such as the one disclosed in patent number 202121783759.3 for dental implants, include a disc-shaped base with positioning holes. The disc-shaped base has multiple sets of mounting portions on its circumferential sidewalls, and these mounting portions extend outwards in a radiating manner on the circumferential sidewalls of the disc-shaped base. Each mounting portion includes multiple mounting rings with mounting holes, and these mounting rings are evenly spaced. Two adjacent mounting rings are connected by a transverse connecting section. This type of titanium mesh structure generally requires cutting and bending during use. Furthermore, the central disc-shaped base is what truly encapsulates the bone column and bone graft. This disc-shaped base has only one positioning hole. However, in clinical practice, the bone column and bone graft are applied to the gum line, which is outside the gums. During bone grafting, the gums are cut open. Without the hole in the titanium mesh, it obstructs blood flow, forcing blood to bypass the mesh and affecting the normal blood supply to the gums, thus hindering normal gingival growth and healing. Moreover, adapting the disc-shaped base to the gum line and bone graft needs requires a large area, and it cannot be cut, as this would also reduce the installation area, leading to instability. Therefore, this titanium mesh structure has poor adaptability.

[0004] To address the aforementioned problems, this utility model document proposes a titanium mesh for dental implants. Utility Model Content

[0005] This invention provides a titanium mesh for dental implants, which facilitates blood supply to the gums and allows for the use of titanium mesh sub-substrate according to actual conditions, making the installation more secure and improving the adaptability of the titanium mesh.

[0006] This utility model provides the following technical solution:

[0007] A titanium mesh for dental implants includes a rectangular titanium mesh main body, with detachable titanium mesh sub-sub bodies on the four side walls of the main body. The sub-sub bodies are strip-shaped plate structures. The main body has a main positioning hole in the center, and multiple auxiliary positioning holes are evenly distributed around the main positioning hole. The side walls of the auxiliary positioning holes are provided with radiating strip-shaped holes. The sub-sub bodies are evenly provided with mounting holes.

[0008] Furthermore, the sidewall of the titanium mesh main substrate is provided with a first groove with a spiral cross-section, and the two ends of the titanium mesh sub-sub substrate are provided with a second groove with a spiral cross-section that matches the first groove.

[0009] Furthermore, the auxiliary positioning holes located at the top corner of the titanium mesh main body have two strip-shaped holes evenly distributed on their sidewalls, the auxiliary positioning holes located at the four edges of the titanium mesh main body have three strip-shaped holes evenly distributed on their sidewalls, and the auxiliary positioning holes located in the middle of the titanium mesh main body have four strip-shaped holes evenly distributed on their sidewalls.

[0010] Furthermore, the sidewall of the titanium mesh substrate is provided with a shearing groove.

[0011] Furthermore, both the main titanium mesh substrate and the secondary titanium mesh substrate have uniformly distributed micropores on one surface.

[0012] In this invention, the detachable titanium mesh sub-base around the main titanium mesh substrate facilitates the connection of the sub-base at different positions by the dentist according to positioning needs. This is simple and convenient, saves materials, and reduces treatment costs for patients. The multiple auxiliary positioning holes on the main titanium mesh substrate not only make it easier for the dentist to select the appropriate position for fixation, but also facilitate blood flow through the titanium mesh to the gums, which is beneficial for gum growth and healing. The strip-shaped holes around the auxiliary positioning holes allow the shape of the main titanium mesh substrate to be adjusted to fit the shape of the gum, ensuring that the shape formed after bone grafting is more closely aligned with the original shape, which is more conducive to the stability of the dental implant later.

[0023] Example:

[0024] Reference Figures 1 to 3 As shown, a titanium mesh for dental implants includes a rectangular titanium mesh main body 1. The four side walls of the titanium mesh main body 1 are detachably provided with titanium mesh sub-bases 2. The titanium mesh sub-bases 2 are strip-shaped plate structures. The titanium mesh main body 1 has a main positioning hole 3 in the middle. A plurality of auxiliary positioning holes 4 are evenly provided around the main positioning hole 3. The side walls of the auxiliary positioning holes 4 are provided with strip-shaped holes 6 in a radiating pattern. The titanium mesh sub-bases 2 are evenly provided with mounting holes 5.

[0025] The detachable titanium mesh sub-base 2 surrounding the main titanium mesh 1 allows the dentist to connect the sub-base 2 at different positions as needed. The sub-base 2 is positioned via mounting holes 5, which in turn positions the main titanium mesh 1. This simple and convenient operation saves materials and reduces treatment costs for patients. The multiple auxiliary positioning holes 4 on the main titanium mesh 1 not only facilitate the dentist in selecting appropriate locations for fixation but also allow blood to flow through the titanium mesh to the gums, promoting gum growth and healing. The strip-shaped holes 6 surrounding the auxiliary positioning holes 4 allow for shape adjustment on the main titanium mesh 1 corresponding to the holes 4, adapting the shape to the shape of the gum. This ensures a closer fit between the grafted bone and the original shape, enhancing the stability of the implant later.

[0026] The sidewall of the titanium mesh main substrate 1 is provided with a first groove 8 with a spiral cross-section, and the two ends of the titanium mesh sub-substrate 2 are provided with a second groove 9 with a spiral cross-section that matches the first groove 8.

[0027] The titanium mesh main substrate 1 and the titanium mesh sub-sub substrate 2 are connected by two spiral-shaped first slots 8 and second slots 9, and the connection structure is firm. The titanium mesh main substrate 1 and the titanium mesh sub-sub substrate 2 can slide relative to each other, but they will not separate. After fixing the titanium mesh sub-sub substrate 2 through the mounting hole 5, relative sliding will be avoided. At the same time, the titanium mesh sub-sub substrate 2 can also tighten and fix the titanium mesh main substrate 1.

[0028] The auxiliary positioning hole 4 located at the top corner of the titanium mesh main body 1 has two strip holes 6 evenly arranged on its side wall, the auxiliary positioning hole 4 located at the 14 edges of the titanium mesh main body 1 has three strip holes 6 evenly arranged on its side wall, and the auxiliary positioning hole 4 located in the middle of the titanium mesh main body 1 has four strip holes 6 evenly arranged on its side wall.

[0029] The auxiliary positioning holes 4 located at different positions on the titanium mesh main body 1 can be bent to adapt to the shape adjustment of the jawbone at different positions without affecting the overall structure of the titanium mesh. This makes the shape of the bone graft more consistent with the original jawbone shape, improving the patient's comfort and stability of the dental implant.

[0030] The side wall of the titanium mesh substrate 1 is provided with a shearing groove 10.

[0031] The cutting slot 10 facilitates the doctor's trimming of the titanium mesh main body 1 to meet the needs of different bone graft shapes in different locations in clinical practice, while the auxiliary positioning hole 4 on the titanium mesh main body 1 can meet the installation and positioning of the trimmed titanium mesh main body 1.

[0032] The titanium mesh main substrate 1 and the titanium mesh sub-substrate 2 are uniformly provided with micropores 7 on one surface.

[0033] The ultra-microporous design creates a layer of connective tissue between the titanium mesh and the new bone, which blocks the growth of gingival tissue and selectively excludes the implantation of tissue epithelium and connective tissue, thereby promoting osteoblast proliferation, affecting the shape of the bone, and ensuring the stability of the dental implant.

[0034] During use, the doctor can trim the titanium mesh main substrate 1 according to the location and shape of the bone graft. Alternatively, a titanium mesh sub-substrate 2 can be connected to the side of the main substrate 1. After filling the bone graft site with bone powder and bone columns, the main substrate 1 is used to wrap the bone powder and bone columns. The main substrate 1 is then positioned and fixed using titanium screws in the main positioning hole 3. Then, the main substrate 1 is fixed using titanium screws in the appropriate auxiliary positioning hole 4. If the titanium mesh sub-substrate 2 is used, it is fixed at the mounting hole 5 using titanium screws, thus securing the titanium mesh. The titanium mesh sub-substrate 2 is used to fix the titanium mesh main substrate 1. Since the surface of the bone graft site is not flat, the doctor adjusts the flatness of the titanium mesh main substrate 1 by pressing around the positioning holes, so that the shape of the titanium mesh main substrate 1 is more in line with the original shape of the gum. At the same time, it makes the titanium mesh main substrate 1 fit the bone powder column better, which is conducive to the formation of the bone powder column. The side of the titanium mesh main substrate 1 and the titanium mesh sub-substrate 2 with micropores 7 faces the bone powder column. On the one hand, it prevents the growth of the gums from affecting the shape of the bone powder column, and on the other hand, it avoids osteoblast proliferation.

[0035] In practical use, since the thickness of the titanium mesh used in clinical practice is usually 0.1mm, 0.2mm and 0.3mm, doctors cannot quickly distinguish the thickness of the titanium mesh when using it. Therefore, the shape of the main positioning hole 3 is set to be circular, rectangular and triangular to facilitate doctors to quickly identify the thickness of the titanium mesh.

[0036] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
