[0042] Please refer to the following: Figures 1 to 10 The anti-slip dental implant system provided by this utility model will now be described. The anti-slip dental implant system includes: an implant 1, a screw 2, and an implant abutment 3; the implant 1 has a cavity 11, and the inner wall of the cavity 11 has a first internal thread 111; the screw 2 includes: a head 21 and a shank 22 connected to the head 21 and having an external thread 221; one end of the implant abutment 3 is inserted into the cavity 11 in a predetermined direction F; the implant abutment 3 has a mounting hole 31; the shank 22 passes through the mounting hole 31 and is threadedly connected to the first internal thread 111; the inner wall of the mounting hole 31 has a second internal thread 311 that can mate with the external thread 221.

[0043] Thus, the implant 1 has a cavity 11, and one end of the implant abutment 3 can be inserted into the cavity 11 in a predetermined direction F; the inner wall of the cavity 11 has a first internal thread 111; the implant abutment 3 has a mounting hole 31; the screw 2 includes: a head 21 and a rod 22 connected to the head 21, the rod 22 having an external thread 221; the rod 22 can pass through the mounting hole 31, and after the rod 22 passes through the mounting hole 31, the external thread 221 on the rod 22 can be threadedly connected with the first internal thread 111, that is, the implant abutment 3 is detachably fixed to the implant 1 by the screw 2; the inner wall of the mounting hole 31 has a second internal thread 311 that can cooperate with the external thread 221, and when the rod 22 encounters the second internal thread 311 during the process of passing through the mounting hole 31, the external thread 221 on the rod 22 can be threadedly connected with the second internal thread 311, and the rod can be rotated. Part 22 allows the rod part 22 to move along the mounting hole 31. When the rod part 22 moves along the mounting hole 31 and the external thread 221 and the second internal thread 311 separate, the rod part 22 can continue to slide along the mounting hole 31. However, if the rod part 22 needs to be pulled out of the mounting hole 31, the external thread 221 will encounter the second internal thread 311 again. The rod part 22 can only be pulled out of the mounting hole 31 by engaging with the second internal thread 311 and rotating the rod part 22. The rod part 22 cannot be directly pulled out of the mounting hole 31, thus preventing the rod part 22 inserted in the mounting hole 31 from sliding directly out of the mounting hole 31. After the external thread 221 on the rod part 22 passes through the second internal thread 311, the rod part 22 can continue to move along the mounting hole 31 and be threadedly connected with the first internal thread 111, thereby fixing the planting base 3 and the implant 1.

[0044] In one embodiment, the rotating rod 22 can be achieved by using a screwdriver to engage with the head 21 and tighten the screw 2.

[0045] In one embodiment, the bottom of the cavity 11 is a threaded hole with a second internal thread 311.

[0046] In one embodiment, the mounting hole 31 extends along a predetermined direction F.

[0047] In one embodiment, the guide hole 32 extends along a predetermined direction F.

[0048] In one embodiment, the mounting hole 31 and the guide hole 32 are coaxially arranged.

[0049] In one embodiment, the mounting hole 31 has a circular cross-section.

[0050] In one embodiment, the cross-section of the guide hole 32 is circular.

[0051] In one embodiment, the head 21 is cylindrical. In another embodiment, the diameter of the head 21 is larger than the inner diameter of the mounting hole 31.

[0052] Further, please refer to Figures 1 to 10 As a specific embodiment of the anti-slip dental implant system provided by this utility model, it further includes: a guide hole 32; the guide hole 32 is formed on the implant abutment 3; the guide hole 32 allows the head 21 and the shaft 22 to pass through; the guide hole 32 communicates with the mounting hole 31. Thus, the head 21 and the shaft 22 of the screw 2 can move along the guide hole 32 towards the mounting hole 31; and the shaft 22 can enter the mounting hole 31 along the guide hole 32.

[0053] Further, please refer to Figures 1 to 10 As a specific embodiment of the anti-slip dental implant system provided by this utility model, the inner wall of the cavity 11 has a slot 112, and the implant abutment 3 has a boss 33 inserted into the slot 112. In this way, after the boss 33 is inserted into the slot 112, the implant abutment 3 and the implant 1 are not prone to relative rotation.

[0054] Further, please refer to Figures 1 to 10 In one specific embodiment of the anti-slip dental implant system provided by this utility model, the boss 33 and the slot 112 extend along a predetermined direction F. Thus, the boss 33 can slide into the slot 112 along the predetermined direction F; the cooperation between the slot 112 and the boss 33 can prevent the implant abutment 3 from rotating about a direction perpendicular to the predetermined direction F.

[0055] Further, please refer to Figures 1 to 10 As a specific embodiment of the anti-slip dental implant system provided by this utility model, there are multiple slots 112 and multiple protrusions 33; the multiple slots 112 and multiple protrusions 33 correspond one-to-one; the multiple slots 112 are arranged in sequence around the outside of the implant abutment 3. In this way, the multiple slots 112 and multiple protrusions 33 cooperate with each other to enhance the ability to prevent the implant abutment 3 from rotating relative to the implant 1.

[0056] Further, please refer to Figures 1 to 10 As a specific embodiment of the anti-slip dental implant system provided by this utility model, the intersection of the boss 33 and the implant abutment 1 has a milled groove 34 formed by milling. In this way, forming the milled groove 34 can remove burrs at the intersection of the boss 33 and the implant abutment 3.

[0057] Further, please refer to Figures 1 to 10 As a specific embodiment of the anti-slip dental implant system provided by this utility model, when the external thread 221 of the rod 22 is threadedly connected to the first internal thread 111, the second internal thread 311 is separated from the external thread 221. This avoids the external thread 221 being affected by the second internal thread 311 when it engages with the first internal thread 111.

[0058] Further, please refer to Figures 1 to 10 As a specific embodiment of the anti-slip dental implant system provided by this utility model, a reserved gap 113 is provided between the front end of the implant abutment 3 and the inner wall of the cavity 11 in the predetermined direction F. Thus, the reserved gap 113 in the predetermined direction F allows for further movement or deformation of the implant abutment 3, facilitating sufficient compression between the implant abutment 3 and the side wall of the cavity 11. In one embodiment, the implant abutment 3 is clamped between the head 21 and the side wall of the cavity 11.

[0059] In one embodiment, the cross-section of the cavity 11 gradually narrows in the predetermined direction F. Thus, as the implantation abutment 3 moves along the predetermined direction F, the contact between the implantation abutment 3 and the inner wall of the cavity 11 gradually becomes closer.

[0060] Further, please refer to Figures 1 to 10 In one specific embodiment of the anti-slip dental implant system provided by this utility model, the sidewall at the opening of the cavity 11 is a conical inner wall 114, and the outer surface of the implant abutment 3 has a conical outer wall 35 that fits against the conical inner wall 114. Thus, the conical inner wall 114 and the conical outer wall 35 fit together to provide better sealing.

[0061] Further, please refer to Figures 1 to 10 As a specific embodiment of the anti-slip dental implant system provided by this utility model, the inner wall of the cavity 11 has an annular flange 12 surrounding the outer side of the implant abutment 3; the boss 33 abuts against the inner wall of the annular flange 12. In this way, the implant abutment 3 and the inner wall of the cavity 11 are in close contact, improving the bending resistance of the implant abutment 3.

[0062] In one embodiment, the front edge of the boss 33 has a chamfer 331 in a predetermined direction F. This facilitates the front end of the boss 33 sliding along the inner wall of the cavity 11.

[0063] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
