[0002] Dentistry, one of the medical disciplines, is generally combined with the stomatology department in a large hospital, and mainly treats diseases related to teeth and periodontal tissues. Dental implant surgery is the best repair method for tooth loss at present, and its principle is to drill an implant hole in advance on the alveolar bone, and then rotate the implant into the implant hole to make it bone-bonded with the alveolar bone. The titanium mesh is a medical device used for bone augmentation surgery in the field of dental implants.

It should be further noted that unless explicitly defined and limited, if the terms "arranged", "connected", "connected" appear, they should be understood broadly, for example, they can be fixedly connected, or detachably connected, or integrally connected; they can be mechanically connected, or directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood specifically.

[0032] The present application provides a matching implant titanium mesh and system, Figure 1 And Figure 2 The structure diagram of the matching implant titanium mesh system in the present application and the structure diagram of the matching implant titanium mesh in the present application are shown, as shown in Figure 1 And Figure 2 A matching implant titanium mesh for integrally forming to a preset angle to form a bone space with the area wrapped by the alveolar bone, comprising an integrally formed titanium mesh edge, a pore structure, the pore structure is located in the titanium mesh edge, and the pore structure is connected with the titanium mesh edge. In actual operation, due to individual differences, the size and shape of the alveolar bone will show complex and diverse changes. Before implanting the titanium mesh, the titanium mesh should be cut to a suitable shape according to the size and shape of the specific alveolar bone defect of the patient, to ensure that the edge of the titanium mesh precisely fits the contour of the alveolar bone, and to play an important role in guiding bone tissue regeneration and maintaining the stability of the alveolar bone.

[0033] Further, the pore structure has a first hole 1, a second hole 2 and a third hole 3, the first hole 1 is a circular hole, the second hole 2 is a polygonal hole, the edge of the first hole 1 serves as a side of part of the second hole 2, and at least one end of the common side of the two adjacent second holes 2 is connected with the third hole 3, the first hole 1 and the second hole 2 are used for connecting the upper surface of the connecting abutment 41 and the support nail 42; the third hole 3 is used for the locking piece 5 to pass through, to fix the titanium mesh body on the alveolar bone.

[0034] Further, the diameter of the first hole 1 is greater than the diameter of the third hole 3, the diameter of the first hole 1 ranges from 2.0-3.5mm, the diameter of the third hole 3 ranges from 0.8-2.0mm, and the narrowest distance of the second hole 2 ranges from 2.0-3.0mm. The first hole 1 and the second hole 2 are used for connecting the upper surface of the abutment, and the diameter of the first hole 1 is greater than the diameter of the second hole 2. Due to the anatomical differences of different patients, the distance between multiple teeth is random, and the distance between adjacent implants is generally 7-10mm. Generally, the titanium mesh cannot accurately match the specific orientation of two implants. Through the structural design in the present application, it is beneficial to diversified connection and adaptation, and the distance is more adjustable and multiple implants can be implanted. At the same time, during oral functional activities such as mastication, complex occlusal forces are generated. The titanium mesh in the present application can implant multiple implants, that is, it can evenly distribute these occlusal forces to the entire support area, avoiding excessive force on a single implant, thereby improving the overall stability of multiple implants and reducing the risk of implant loosening or failure. And the first hole 1 can disperse stress on a larger contact area, reducing the phenomenon of local stress concentration, like spreading the pressure to a larger platform, thereby protecting the connection structure from deformation due to stress concentration.

[0035] Further, the first hole 1 is arranged at the center or other position of the titanium mesh, preferably, the first hole 1 is arranged at the center of the titanium mesh, and the area ratio of the first hole 1, the second hole 2 and the third hole 3 is greater than 50%, which is beneficial to blood circulation and nutrient supply, and facilitates the injection of bone graft material.

[0036] Further, as shown in Figure 2 A-A is the center axis of the first hole 1, the second hole 2 is a polygonal hole, each side is a first line segment or a second line segment, and the angle between the second line segment and the center axis of the first hole is 45°. The structural design of 45° makes the titanium mesh form a basic unit combination similar to a square, the mechanical stability in each direction is relatively balanced, which can better resist forces from different directions, especially when bearing oblique forces, the overall structural strength is higher, and it can also provide a relatively regular attachment edge for cell attachment and growth, which is more conducive to bone cell growth and tissue reconstruction.

[0037] Specifically, the first line segment is the side of the first hole or the third hole; and the second line segment is a line segment connecting the first hole and the third hole or a line segment connecting two third holes.

[0038] Further, the width of the edge of the second hole 2 ranges from 0.2-0.6mm, and the length ranges from 0.4-2.0mm, wherein the length of the edge connected to the first hole 1 is less than the length of the edge connected to the third hole 3.

[0039] Specifically, the material of the titanium mesh is any one of pure titanium or titanium alloy, and the titanium mesh has a uniform thickness of 0.1-0.5 mm.

[0040] A titanium mesh system matching an implant, as shown in Figure 3 、 Figure 4 、 Figure 5 The titanium mesh is installed on the surface of the alveolar bone through the connecting member and the locking member.

[0041] Further, the locking member is matched with the third hole 3 to fix the titanium mesh on the alveolar bone, and the locking member is a cylindrical structure with threads on the surface. In actual operation, a suitable locking member is selected, passes through the third hole 3 of the titanium mesh and is implanted into the alveolar bone, and is fixed by relying on friction and mechanical fitting. After the locking member is implanted, an outward tension is generated on the titanium mesh, which tightly presses the titanium mesh on the surface of the alveolar bone. This tension enables the titanium mesh to firmly adhere to the alveolar bone and prevents the titanium mesh from being displaced during oral functional activities.

[0042] Further, the connecting member is any one of an adapter abutment 41 or a support pin 42.

[0043] Specifically, when the connecting member is the adapter abutment 41, the adapter abutment 41 is a columnar structure, the top of which is provided with a disc-shaped first protrusion, the outer diameter of the first protrusion is 1.8-2.8 mm and the height thereof is the same as the thickness of the titanium mesh, the middle part of the adapter abutment is a main body part, the outer diameter of which is greater than the inner diameter of the first hole, in the installation process, the first protrusion is positioned and installed in the first hole or the second hole, the titanium mesh abuts against the top end of the main body part and is limited, at the same time, a cover screw is fixedly installed on the top of the first protrusion, and the titanium mesh is further fixed on the adapter abutment 41. The lower part of the main body part is an extension part for connecting with the implant.

[0044] Specifically, when the connecting member is the support pin 42, the support pin 42 includes a pin head and a pin body, the top end of the pin body is provided with a second protrusion, the outer diameter of the second protrusion is 1.8-2.8 mm and the height thereof is the same as the thickness of the titanium mesh, the second protrusion is positioned and installed in the second hole, and the titanium mesh is fixedly installed on the alveolar bone through the cooperation of the pin head and the pin body. The support pin 42 plays a role of supporting the titanium mesh body, increases the overall stability of the titanium mesh and avoids deformation of the titanium mesh caused by complex oral movements.

[0045] In the actual operation, first, the implant is implanted in the operation area of the patient, and the appropriate titanium mesh is cut according to the number of implants and the distance between them, and the precise matching of the titanium mesh, the adapter base 41 and the multiple implants is realized through the selection of a plurality of second holes 2 and the micro movement of the protrusions, and the stable cooperation of the titanium mesh and the implant is achieved. According to the actual situation, the support nail 42 can be used to increase the overall stability of the titanium mesh and the implant. At the same time, the locking part is used to further fix the titanium mesh around, and then the bone powder is filled through the holes of the titanium mesh.

[0046] The specific embodiments of the present application are described in detail above, and for those skilled in the art, without departing from the principles of the present application, some improvements and modifications can be made to the present application, and these improvements and modifications also belong to the protection scope of the claims of the present application.
