Description

Technical Field

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

[0002] In dental implant surgery, the amount of alveolar bone is one of the key factors affecting the successful placement of implants. For patients with alveolar bone defects, bone augmentation surgery is often necessary to restore bone volume and meet the implant placement requirements. Titanium mesh, as a commonly used bone augmentation material, has good biocompatibility and mechanical strength, providing stable support for bone tissue and promoting bone regeneration.

[0003] However, traditional titanium mesh implants present several challenges in their application. First, the mesh needs to be removed after bone growth is complete, typically requiring a flap surgery. Because the mesh is tightly integrated with the bone and possesses inherent strength and toughness, removal often necessitates a large flap area. This not only increases surgical complexity but can also lead to soft tissue damage, prolonging recovery time, increasing the risk of postoperative infection, and exacerbating patient discomfort. Second, stress concentration and deformation are significant issues. Traditional titanium mesh implants have a uniform mesh structure, making them prone to stress concentration under pressure. This can cause the mesh to collapse or shift, negatively impacting bone regeneration.

[0004] Currently, some improved titanium mesh designs have attempted to address these issues, such as by optimizing the mesh shape or adding detachable structures to reduce trauma during removal. However, these designs often increase manufacturing complexity and have limited effectiveness in practical applications, failing to fundamentally solve the problems of large flap area, extensive surgical trauma, and easy displacement and deformation of the titanium mesh.

[0005] Chinese patent CN218572364U discloses a titanium mesh, including a titanium mesh edge and a porous structure. The porous structure is located within the edge of the titanium mesh and is connected to the edge of the titanium mesh. A groove extending along a predetermined guide line is formed on the porous structure. A rod is disposed within the groove, with its opposite ends connected to the inner wall of the groove. The porous structure is bent to a preset angle along the predetermined guide line. This titanium mesh, by having a groove extending along the predetermined guide line, facilitates bending and deformation along the guide line. Simultaneously, the strength at the groove is relatively weak, making it easier for the titanium mesh to break at the groove, facilitating segmented removal and reducing the flap area during later removal. Since the bending deformation point of the titanium mesh is located at the ridge top of the mesh, the groove must be positioned at the ridge top after bending.

[0006] Because the ridges of the titanium mesh are stress-bearing areas, the titanium mesh needs to maintain its stress-bearing capacity for a long time while it is placed in the patient's mouth. Designing the weakest point of the mesh at the ridge makes it easier to place the titanium mesh during surgery, but while it is placed in the patient's mouth, the titanium mesh is subjected to the force from the ridge for a long time, which can easily lead to stress concentration and the risk of displacement or breakage of the titanium mesh. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a dental implant titanium mesh that can be easily removed in sections and has reduced the risk of displacement and breakage during placement.

[0008] The technical solution adopted by this utility model to solve its technical problem is: a dental implant titanium mesh, including a titanium mesh body that is curved into an arch shape. The titanium mesh body includes a titanium mesh edge and a porous structure disposed in the titanium mesh edge. One side of the titanium mesh body is provided with a fragile and easily broken structure. The fragile and easily broken structure includes a groove extending from one end of the titanium mesh body to the other end. At least one set of support rods is provided in the groove.

[0009] The support rod assembly consists of two support rods that are inclined to both sides of the width direction of the groove and intersect at an X-shape. The two ends of the support rods are connected to the inner walls of both sides of the groove. A fracture guide groove is provided at the intersection of the two support rods of the support rod assembly.

[0010] Furthermore, the support rod is a sheet-like structure with a thickness less than its width, and the width direction of the support rod is along the inner wall thickness direction of the groove, and the width of the support rod is equal to the inner wall thickness of the groove.

[0011] Furthermore, the support rod group is a multiple group, and the support rod groups are arranged at intervals along the groove.

[0012] Furthermore, the fracture guide groove is disposed on the side of the intersection of the two support rods of the support rod group, and in two adjacent support rod groups, the fracture guide groove of one support rod group is disposed on one side of the intersection of the two support rods of the support rod group, and the fracture guide groove of the other support rod group is disposed on the other side of the intersection of the two support rods of the support rod group.

[0013] Furthermore, the easily broken and weak structure is provided on the cheek side of the titanium mesh body.

[0014] Furthermore, the pore structure at the ridges of the titanium mesh body is a regular hexagonal pore.

[0015] The beneficial effects of this invention are as follows: The dental implant titanium mesh of this invention has a fragile, easily broken structure placed on one side of the titanium mesh body. This facilitates the breaking of the titanium mesh into two parts at the groove of the fragile, easily broken structure, making it easier to remove the titanium mesh in sections. This reduces the flap area during later removal of the titanium mesh, and the strength of the titanium mesh ridge is not affected, ensuring a large load-bearing capacity. It also reduces the risk of lateral stress, displacement, and deformation. Although the fragile, easily broken structure on the side of the titanium mesh weakens its lateral strength, the stress it bears is relatively small, and the risk of stress, displacement, and deformation is also reduced. Combined with the lateral gingival soft tissue, this better ensures that the titanium mesh will not shift or break during placement, thus better guaranteeing the treatment effect of bone augmentation surgery.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, this utility model discloses a titanium mesh for dental implantation, comprising a curved, arched titanium mesh body 1. The specific curvature of the titanium mesh body 1 is customized according to the patient. The titanium mesh body 1 includes a titanium mesh edge 11 and a porous structure 12 disposed within the titanium mesh edge 11. One side of the titanium mesh body 1 is provided with a fragile, easily broken structure. The fragile, easily broken structure includes a groove 13 extending from one end of the titanium mesh body 1 to the other end. At least one set of support rods 14 is provided within the groove 13. The support rods 14 consist of two support rods 141 that are inclined to both sides of the width direction of the groove 13 and intersect at an X-shape. The two ends of the support rods 141 are respectively connected to the inner walls of both sides of the groove 13. A fracture guide groove 142 is provided at the intersection of the two support rods 141 of the support rods 14.

[0022] The titanium mesh body of this invention can be bent and formed using a mold before surgery.

[0023] In the use of this novel dental implant titanium mesh, it is typically fixed to the alveolar bone with fixing screws. The support rod assembly connects the two sides of the support groove, ensuring that the strength of the titanium mesh groove 13 meets the requirements. The support rod assembly 14 consists of two support rods 141 that are inclined to both sides of the width direction of the groove 13 and intersect at an X-shape. The support rod assembly 14 has better support performance and can better support and limit the titanium mesh on both sides of the groove 13 in multiple directions, which can better ensure that the two sides of the titanium mesh groove are not easily displaced or deformed. A fracture guide groove 142 is provided at the intersection of the two support rods 141 of the support rod assembly 14, which facilitates the breaking or cutting of the support rod assembly 14 at the fracture guide groove 142, thereby facilitating the breaking of the titanium mesh into two parts from the groove, making it easier to remove the titanium mesh in sections and reducing the flap area when removing the titanium mesh later. Because the titanium mesh in dental implants requires connection between the two ends of its ridge (arch portion) and the alveolar bone during installation, the force on the sides of the titanium mesh is much less than the downward pressure borne by the ridge. Furthermore, the sides of the titanium mesh are constrained by the soft tissue of the surrounding tissue, making them relatively less prone to deformation and displacement. This invention places a fragile, weak structure on one side of the titanium mesh body 1, without affecting the strength of the ridge. This ensures greater load-bearing capacity and reduces the risk of lateral stress, displacement, and deformation. Although the fragile, weak structure weakens the lateral strength of the titanium mesh, the stress it experiences is relatively small, reducing the risk of stress, displacement, and deformation. Combined with the soft tissue of the surrounding gum tissue, this design better ensures that the titanium mesh will not shift or break during placement.

[0024] The support rod 141 is preferably inclined at 15° to 45° relative to the width direction of the groove 13. In this embodiment of the present invention, the support rod 141 is inclined at 30° relative to the width direction of the groove 13.

[0025] The support rod 141 can be a circular structure or a sheet-like structure with a thickness less than its width. Since the titanium mesh is more prone to outward bending and deformation during installation and use, to facilitate breakage during later removal and to reduce the possibility of outward bending deformation from the groove, this invention includes... Figure 2 and Figure 3 As shown, preferably, the support rod 141 is a sheet-like structure with a thickness a less than its width b. The width direction of the support rod 141 is along the thickness direction of the inner wall of the groove 13, and the width of the support rod 141 is equal to the thickness of the inner wall of the groove 13. The width of the support rod 141 is preferably between 0.4 and 0.5 mm.

[0026] The number of support rod groups 14 is generally selected according to the length of the tank 13 to ensure the strength of the titanium mesh. When there are multiple support rod groups 14, they are spaced apart along the tank 13. The specific spacing between the support rod groups 14 can be determined experimentally.

[0027] The fracture guide groove 142 can be disposed on the outer or inner surface of the intersection of the two support rods in the support rod assembly, or on the side of the intersection of the two support rods. Considering the stress conditions of the titanium mesh, disposing the fracture guide groove 142 on the side of the intersection of the two support rods has a relatively smaller impact on the strength of the titanium mesh. To further reduce the impact of the fracture guide groove 142 on the strength of the titanium mesh, such as... Figure 2 As shown, in two adjacent support rod groups 14, the fracture guide groove 142 of one support rod group 14 is provided on one side of the intersection of the two support rods 141 of the support rod group 14, and the fracture guide groove 142 of the other support rod group 14 is provided on the other side of the intersection of the two support rods 141 of the support rod group 14.

[0028] The easily broken, weak structure can be provided on the cheek side or tongue side of the titanium mesh body 1. To facilitate subsequent segmented removal of the titanium mesh, in this invention, preferably, the easily broken, weak structure is provided on the cheek side of the titanium mesh body 1.

[0029] The pores in the porous structure can be of various shapes. Considering the need for high strength at the ridge tip, in this invention, the porous structure 12 at the ridge tip of the titanium mesh body 1 is preferably a regular hexagonal hole. The regular hexagonal hole structure 12 at the ridge tip of the titanium mesh body 1 not only provides a channel for osteoblast formation and blood supply to the alveolar bone, but also provides stress dispersion capabilities, improving the strength of the titanium mesh and its retention in the patient's mouth.
