Description

Technical Field

[0001] This utility model belongs to the technical field of dental implant systems, and more specifically, relates to a dental implant. Background Technology

[0002] Dental implants are very common in modern life. The implantation process typically involves first placing the implant in the mouth. The top of the implant usually has a cavity, and then an abutment is prepared and its base is inserted into the cavity of the implant. The outer surface of the implant usually has external threads, which are used to install the implant into a mounting hole in the oral bone. Before the implant is installed into the mounting hole, an internal thread that perfectly matches the external threads is usually created on the inner wall of the mounting hole using a tapping drill. This process is inefficient.

[0003] The implant can be referred to in (Chinese Utility Model Patent; Publication No.: CN220109870U; Subject Title: A Hole-Free Structure, Implant and Dental Implant Device; Publication Date: 2023-12-01); the cavity can be referred to in the channel of CN220109870U.

[0047] Further, please refer to Figures 1 to 5 In one specific embodiment of the dental implant provided by this utility model, the number of cutting grooves 3 is multiple. Thus, multiple cutting grooves 3 can enhance the self-tapping capability of the external thread 2 at different locations.

[0048] Further, please refer to Figures 1 to 5 As a specific embodiment of the dental implant provided by this utility model, multiple cutting grooves 3 are arranged sequentially at intervals in the direction surrounding the rod 1. In this way, the cutting grooves 3 are independent of each other and will not directly affect each other.

[0049] Further, please refer to Figures 1 to 5 As a specific embodiment of the dental implant provided by this utility model, the cutting groove 3 includes: a plurality of interconnected first grooves 31 located on the external thread 2. Thus, the plurality of first grooves 31 can enhance the self-tapping capability at different positions on the external thread 2. Furthermore, the first grooves 31 at different positions on the external thread 2 can provide deformation space at different positions on the external thread 2.

[0050] Further, please refer to Figures 1 to 5 As a specific embodiment of the dental implant provided by this utility model, the cutting groove 3 further includes: a second groove 32 located on the second end 12 of the rod 1; and a plurality of first grooves 31 communicating with the second groove 32. This facilitates the simultaneous processing of the first grooves 31 and the second grooves 32.

[0051] Further, please refer to Figures 1 to 5 As a specific embodiment of the dental implant provided by this utility model, the rod 1 extends in a straight direction.

[0052] Further, please refer to Figures 1 to 5 As a specific embodiment of the dental implant provided by this utility model, the edge of the cutting groove 3 has a cutting edge 33. Thus, the cutting edge 33 can cut the inner wall of the mounting hole to improve the self-tapping capability of the external thread 2.

[0053] In one embodiment, each of the first grooves 31 has a cutting edge 33 on its edge.

[0054] In one embodiment, each of the second grooves 32 has a cutting edge 33 on its edge.

[0055] In one embodiment, the two ends of the rod 1 are an upper section and a lower section, respectively (in one embodiment, the upper end is...). Figure 1 The upper half of the middle rod 1, the lower end is Figure 1 The lower half of the middle rod 1 has a first thread on the upper outer surface and a second thread on the lower outer surface.

[0056] In one embodiment, the pitch of the first thread and the pitch of the second thread are different, and the depth of the groove in the first thread is different from the depth of the groove in the second thread.

[0057] In one embodiment, the first thread groove transitions to the second thread groove via a transition section. When the tool cuts from bottom to top to the transition section, it is slowly lifted and widened to both sides to form the transition section. This facilitates the machining of the first and second threads at the transition point. In one embodiment, the lower toolpath completes the forming process in one pass, while the upper toolpath completes the forming process in two passes.
