Detailed Implementation

[0032] 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.

[0033] This utility model provides, for example Figures 1-5 A split-type cap for immediate planting, shown, includes:

[0034] Threaded rod 1;

[0035] Top cap 2, top cap 2 is set on the top of threaded rod 1;

[0036] Connecting component 3 is located at the connection between top cap 2 and threaded rod 1, and is used to connect threaded rod 1 and top cap 2.

[0037] Fixing component 4 is located at the connection between the top cap 2 and the threaded rod 1. Fixing component 4 is used to fix the top cap 2 and the threaded rod 1.

[0038] Restriction component 5 is disposed at the top of threaded rod 1 and is used to restrict the top cap 2 from rotating at the top of threaded rod 1.

[0039] It should be noted that the original one-piece healing abutment was designed as a split type, consisting of a threaded rod 1 and a top cap 2. The shape of the top cap 2 is designed differently according to the teeth in different locations, such as an inverted triangle for incisors, an inverted triangle for canines, and an inverted trapezoid (oblique quadrilateral) for molars. In use, the implant is first inserted into the alveolar bone, and then different top caps 2 are made according to the teeth in different locations. When the top cap 2 needs to be installed, the top cap 2 corresponding to the tooth is removed, and the top cap 2 is connected to the threaded rod 1 through the connecting component 3. The different shapes of the top cap 2 are used to reduce the gap between the top cap 2 and the tooth.

[0040] Specifically, the connecting component 3 includes a connecting block 302 fixedly connected to the top of the threaded rod 1, and a connecting groove 301 is provided at the bottom of the top cap 2, with the connecting block 302 inserted into the inside of the connecting groove 301.

[0041] Specifically, the top of the cap 2 has a hexagonal groove 201, which is used to rotate the cap 2.

[0042] It should be noted that the hexagonal groove 201 is for inserting a hexagonal wrench. When it is necessary to rotate the top cap 2, the hexagonal wrench is inserted into the hexagonal groove 201, and the top cap 2 is rotated by the hexagonal wrench. Since the top cap 2 and the threaded rod 1 are restricted by the limiting component 5, the rotation of the top cap 2 drives the threaded rod 1 to rotate, thereby realizing the insertion and removal of the threaded rod 1 into the implant.

[0043] Specifically, fixed component 4 includes:

[0044] Bolt 403, the inner wall of the bottom end of the hexagonal groove 201 is provided with a mounting groove 401, the bolt 403 is inserted and connected inside the mounting groove 401, and a positioning element 6 is provided at the connection between the bolt 403 and the top cap 2 to limit the movement of the bolt 403.

[0045] Through slot 402 is formed on the inner wall of the bottom end of mounting slot 401, and bolt 403 is inserted and connected inside through slot 402;

[0046] The threaded groove 404 is located at the top of the connecting block 302, and the bolt 403 is threadedly inserted into the inside of the threaded groove 404.

[0047] It should be noted that the mounting slot 401 is adapted to the screw head of the bolt 403, allowing the screw head of the bolt 403 to pass through it. The through slot 402 is a cylindrical slot, allowing the threaded part of the bolt 403 to pass through it. The diameter of the through slot 402 is smaller than the diameter of the screw head, preventing the screw head of the bolt 403 from passing through the inside of the through slot 402. When it is necessary to fix the top cap 2 and the connecting block 302, the top cap 2 is first placed on the top of the connecting block 302, and then the bolt 403 is used to fix the top cap 2 and the connecting block 302.

[0048] Specifically, positioning component 6 includes:

[0049] Positioning block 602 is fitted onto the middle of bolt 403;

[0050] The positioning groove 601 is formed on the inner wall of the top of the connecting groove 301, and the positioning block 602 is inserted and connected inside the positioning groove 601.

[0051] Specifically, the horizontal cross section of the positioning block 602 is set as an annular shape, and the positioning block 602 is used to restrict the movement of the bolt 403.

[0052] It should be noted that the positioning block 602 is a circular cube, which is fixedly fitted in the middle of the bolt 403. The positioning groove 601 is a cylindrical groove, which allows the positioning block 602 to rotate inside the positioning groove 601. When the bolt 403 needs to move upward, the bolt 403 will drive the positioning block 602 to move upward. However, the positioning block 602 is blocked by the inner wall of the top of the positioning groove 601, preventing it from moving. Thus, the position of the bolt 403 is restricted by the positioning block 602 that restricts movement.

[0053] Specifically, limiting component 5 includes:

[0054] Limiting rod 502 is fixedly connected to the top of connecting block 302;

[0055] A limiting groove 501 is formed on the inner wall of the top of the connecting groove 301, and a limiting rod 502 is inserted and connected inside the limiting groove 501.

[0056] It should be noted that the limiting groove 501 is adapted to the limiting rod 502, and the number of limiting rods 502 is at least two. The number of limiting grooves 501 and limiting rods 502 is the same, so that the limiting rods 502 can be inserted into the interior of the limiting groove 501. The top cap 2 with the limiting groove 501 is restricted by at least two limiting rods 502, so as to prevent the top cap 2 from rotating on the top of the connecting block 302.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
