Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0037] The present utility model provides as Figures 1-4A dental implant short implant body with protruding positioning is shown, including: an implant body 1, the implant body 1 is in threaded fit with the inside of the alveolar bone; an installation base 2, the installation base 2 is fitted to the top of the implant body 1; a pressing mechanism 3, the pressing mechanism 3 is inserted and installed between the implant body 1 and the installation base 2; a plurality of insertion positioning mechanisms 4 are inserted and installed on the implant body 1; an elastic limiting mechanism 5, the elastic limiting mechanism 5 is respectively installed on both sides of the implant body 1, and the elastic limiting mechanism 5 is used to limit the pressing mechanism 3; First, through the external thread provided on the implant body 1, the implant body 1 is in threaded fit with the alveolar bone to realize the installation of the implant body 1. After fitting the installation base 2 to the top of the implant body 1, the pressing mechanism 3 is inserted into the inside of the implant body 1, and then the pressing mechanism 3 is tapped, so that the pressing mechanism 3 presses the insertion positioning mechanism 4, so that the tip of the insertion positioning mechanism 4 penetrates out of the implant body 1 and pierces into the inside of the alveolar bone, thereby preventing the thread between the implant body 1 and the alveolar bone from loosening, making the implant body 1 more stable inside the alveolar bone, and also preventing the dental implant from loosening.

[0038] Among them, the insertion positioning mechanism 4 includes: an insertion nail 41, the tip of the insertion nail 41 faces the direction of the alveolar bone; a pressing slider 42, the pressing slider 42 is connected to the end of the insertion nail 41 away from the tip, and both the insertion nail 41 and the pressing slider 42 are slidably inserted into the implant body 1. A first inclined surface is provided in the direction away from the insertion nail 41 on the pressing slider 42. A first sliding groove is formed in an annular array inside the implant body 1, and the pressing slider 42 is slidably connected to the inner cavity of the first sliding groove. A second sliding groove is formed on the inner wall of the first sliding groove, and the insertion nail 41 is slidably inserted into the inner cavity of the second sliding groove. The insertion positioning mechanism 4 further includes: a limiting block 43, one of the limiting blocks 43 is connected to the pressing slider 42, and the other two limiting blocks 43 are connected to the inside of the first sliding groove. The limiting block 43 is used to position the pressing slider 42. Through the tip provided on the insertion nail 41, it is easier to pierce into the inside of the alveolar bone under tapping. Through the insertion between the insertion nail 41 and the alveolar bone, the thread between the implant body 1 and the alveolar bone is prevented from loosening, making the implant body 1 more stable. By the way of matching the first inclined surface on the pressing slider 42 with the pressing head 32, it is convenient to adjust the direction of the force, so that the vertical movement of the pressing head 32 can press the pressing slider 42, so that the pressing slider 42 can perform horizontal lateral movement under the limitation of the first sliding groove. The two limiting blocks 43 installed inside the first sliding groove limit the limiting block 43 connected to the pressing slider 42 to prevent the pressing slider 42 from sliding randomly inside the first sliding groove, and the limiting block 43 is made of elastic material and can undergo elastic deformation under tapping without affecting the normal sliding of the pressing slider 42 inside the first sliding groove.

[0039] Among them, the extrusion mechanism 3 includes: an insertion rod 31, which is inserted and connected to the inside of the implant 1; an extrusion head 32, which is connected to one end of the insertion rod 31. The extrusion head 32 is arranged in a frustum shape and cooperates with the first inclined surface on the extrusion slider 42. The extrusion mechanism 3 further includes: a limit head 33, which is connected to the other end of the insertion rod 31. A counterbore is provided inside the implant 1, and the extrusion mechanism 3 cooperates with the inner cavity of the counterbore. Through the cooperation between the limit head 33 and the counterbore, the excessive insertion of the insertion rod 31 is prevented. Through the extrusion head 32, it is convenient to mutually extrude and cooperate with the first inclined surface on the extrusion slider 42 to realize the pushing of the extrusion slider 42. By inserting the insertion rod 31 between the implant 1 and the mounting base 2, the relative position between the implant 1 and the mounting base 2 is limited, preventing the detachment of the mounting base 2.

[0040] Specifically, insertion grooves are provided on both sides of the implant 1, and the elastic limit mechanism 5 is fitted inside the insertion grooves. The elastic limit mechanism 5 includes: a fixed block 51, which is fixedly installed inside the insertion groove; a spring 52, one end of which is connected to the fixed block 51; a one-way positioning block 53, which is connected to the other end of the spring 52, and a second inclined surface is provided on the top of the one-way positioning block 53; a limit insertion rod 54, which is movably arranged inside the spring 52, and one end of the limit insertion rod 54 is fixedly connected to the one-way positioning block 53, and the limit insertion rod 54 is slidably inserted through the fixed block 51; a limit plate 55, which is connected to the other end of the limit insertion rod 54. When the extrusion mechanism 3 is struck, the limit head 33 will extrude the second inclined surface on the one-way positioning block 53, so that the one-way positioning block 53 can compress the spring 52 and then retract into the inner cavity of the insertion groove, thus not hindering the normal insertion movement of the extrusion mechanism 3. When the limit head 33 is completely fitted with the counterbore, the limit head 33 no longer contacts and extrudes the one-way positioning block 53. Through the elastic support of the spring 52 for the one-way positioning block 53, the one-way positioning block 53 penetrates out of the inner cavity of the insertion groove to limit the top of the limit head 33, preventing the upward detachment of the extrusion mechanism 3, making the positions of the extrusion mechanism 3 and the insertion and positioning mechanism 4 more stable. Through the sliding insertion between the limit insertion rod 54 and the fixed block 51, the linear movement of the one-way positioning block 53 is more stable. Through the compression deformation of the spring 52, it is convenient to elastically support the one-way positioning block 53, and through the limitation of the limit plate 55, the excessive sliding of the one-way positioning block 53 is prevented.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
