Description

Technical Field

[0001] The utility model belongs to the technical field of dental implant bases, and particularly relates to an anti-loosening dental implant base. Background Art

[0002] With the continuous development of modern society and the continuous improvement of economic level, domestic oral medical technology is also developing continuously. Among the existing oral medical technologies, dental implants, as a modern commonly used tooth replacement treatment technology, its main function is to use implants, implant abutments and crowns to implant artificial teeth into the patient's mouth to replace the patient's missing teeth and facilitate the patient's subsequent eating. In dental implant technology, the implant abutment is a connecting component, and its main function is to connect with the implant and crown respectively to ensure the stability of the crown after it is implanted in the mouth.

[0003] When the existing dental implant abutment is in use, a crown is fixed on the top. The crown is put on the top of the dental implant abutment after applying adhesive, and there is no other limiting and fixing structure. After long-term wear, the viscosity of the adhesive will gradually decrease, causing the crown and the dental implant abutment to loosen and fall off. For this reason, we propose an anti-loosening dental implant abutment. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-loosening dental implant base to solve the problem of poor connection firmness between the dental implant base and the dental crown proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-loosening dental implant abutment, comprising a base sleeved on the top of the implant and a crown sleeved on the top of the abutment, a firm connection mechanism is provided between the crown and the abutment, and a docking mechanism is provided between the abutment and the implant, the firm connection mechanism comprising: a connection limit assembly, provided at the connection between the crown and the abutment; a tight adhesive assembly, provided on the inner side between the crown and the abutment.

[0006] Preferably, the connection limiting assembly includes a connection groove provided at the top end of the abutment and a connection block fixed inside the bottom end of the crown, and the connection block is engaged with the connection groove.

[0007] Preferably, the bottom side surface of the connecting block is provided with sliding grooves at equal distances and sliders symmetrically fixed inside the connecting grooves, and the sliders are slidably connected to the sliding grooves.

[0008] Preferably, the slider is symmetrically provided with limiting grooves on both sides and elastic buckles symmetrically fixed on both sides of the inner wall of the slide groove and adapted to the limiting grooves, and the elastic buckles are engaged and connected with the limiting grooves.

[0009] Preferably, the tight bonding component includes a rubber ring fixed to the inner wall of the bottom end of the crown and an adhesive applied to the inner side of the rubber ring, and the adhesive is fitted and connected to the top side of the abutment.

[0010] Preferably, the docking mechanism includes a docking groove symmetrically provided on the bottom surface of the abutment and a docking block symmetrically fixed on the inner wall of the top end of the implant, and the docking block is engaged with the docking groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model can realize the connection and limiting function between the crown and the abutment through the designed connecting groove, connecting block, sliding groove and sliding block. At the same time, with the designed adhesive applied on the rubber ring, the bottom inner wall of the crown can be tightly and seamlessly fitted with the top side of the abutment through the deformable rubber ring, thereby increasing the bonding effect of the adhesive. Compared with the existing technology, the connection firmness between the crown and the abutment is greatly improved through the cooperation of the adhesive and the limiting connection structure, avoiding looseness.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: an anti-loosening dental implant abutment, comprising a base 2 sleeved on the top of an implant 1 and a crown 3 sleeved on the top of the base 2, a firm connection mechanism is provided between the crown 3 and the base 2, and a docking mechanism is provided between the base 2 and the implant 1, the firm connection mechanism includes: a connection limit component, which is provided at the connection between the crown 3 and the base 2; a tight adhesive component, which is provided on the inner side between the crown 3 and the base 2.

[0020] In this embodiment, preferably, the connection limit assembly includes a connection groove 100 opened at the top of the base 2 and a connection block 101 fixed inside the bottom end of the crown 3. The connection block 101 is engaged with the connection groove 100 to facilitate the connection between the crown 3 and the top of the base 2.

[0021] In this embodiment, preferably, the bottom side surface of the connecting block 101 is provided with sliding grooves 200 at equal distances and sliders 201 symmetrically fixed inside the connecting grooves 100 , and the sliders 201 are slidably connected to the sliding grooves 200 .

[0022] In this embodiment, preferably, limiting grooves 300 are symmetrically provided on both sides of the slider 201, and elastic buckles 301 are symmetrically fixed on both sides of the inner wall of the slide groove 200 and adapted to the limiting grooves 300. By engaging and connecting the elastic buckles 301 with the limiting grooves 300, the slider 201 can be limited deep inside the slide groove 200.

[0023] When the crown 3 and the base 2 need to be fixed together, first apply adhesive 401 to the rubber ring 400 on the inner wall of the bottom of the crown 3, and when the adhesive 401 has not yet solidified, the bottom end of the crown 3 is placed on the top of the base 2, so that the rubber ring 400 is squeezed and fitted with the top side of the base 2, and the connecting block 101 is embedded in the interior of the connecting groove 100, while driving the slider 201 to slide into the interior of the slide groove 200, and then the crown 3 body is rotated to drive the connecting block 101 to rotate inside the connecting groove 100, and drive the slider 201 to move from the opening of the slide groove 200 to the deep inside, while driving the elastic buckle 301 to squeeze and engage with the limiting groove 300, so that the connecting block 101 can be temporarily limited inside the connecting groove 100.

[0024] In this embodiment, preferably, the tight bonding component includes a rubber ring 400 fixed to the inner wall of the bottom end of the crown 3 and an adhesive 401 applied to the inner side of the rubber ring 400. The adhesive 401 is fitted and connected to the top side of the base 2. The rubber ring 400 is adhered to the top side of the base 2 through the adhesive 401. After the adhesive 401 is cured, they can be firmly adhered together. At the same time, the positioning of the slide groove 200 and the slider 201 can effectively prevent the crown 3 and the base 2 from loosening.
