Detailed Description
The present application is described in further detail below with reference to fig. 1.
The embodiment of the application discloses a detachable composite artificial dental implant.
Referring to fig. 1, when a person loses teeth having a chewing function due to aging, etc., the person may have a great influence on the daily eating and chewing behavior, and due to the development of technology, the person may provide the daily chewing ability by implanting a dental implant in the position where the teeth are missing, which is popular because of its high degree of similarity in appearance to real teeth and its aesthetic and practical appearance after implantation.
The implant generally comprises an implant 1, a crown body 3 and an abutment 2 used for connecting the implant 1 and the crown body 3, wherein the implant 1 is embedded into the gum position of a lost tooth of a therapist by screw threads, a stable platform is provided for the crown body 3, the abutment 2 is installed at one end of the implant 1 far away from the embedded gum by screw threads, the crown body 3 is fixed at one end of the abutment 2 far away from the implant 1 by an embedding mode, and the implant cannot well clean oral sundries in a gap between the crown body 3 and the abutment 2 because the crown body 3 is difficult to disassemble, so that the implant is polluted by more bacteria sundries.
In order to solve the above problem, in this embodiment, a fastening screw 30 is inserted into the top of the crown body 3, the fastening screw 30 passes through the middle of the crown body 3 and is screwed into the top of the abutment 2, so that the crown body 3 can be stably installed on the abutment 2, a protruding portion is provided at the middle of one end of the crown body 3 away from the abutment 2, a crown head 4 is installed at the outer side of the protruding portion by screw threads, a contraposition convex ring 5 is integrally formed at one end of the crown body 3 close to the crown head 4, the contraposition convex ring 5 is enclosed at the periphery of the protruding portion, wherein one end face of the contraposition convex ring 5 away from the abutment 2 is provided with an arc surface, and a contraposition groove 50 is provided at a position of the crown head 4 close to one end of the crown body 3 and corresponding to the contraposition convex ring 5.
By utilizing the alignment function of the alignment convex ring 5 and the alignment groove 50, a therapist can more accurately and rapidly screw the crown head 4 into the top of the crown body 3 so as to complete the installation of the crown head 4 and the crown body 3, and the outer contour of a combined body formed by the crown head 4 and the crown body 3 is similar to the outer contour of a real tooth.
In order to further improve the stability between the crown head 4 and the crown body 3, in the embodiment, the elastic rubber pad 40 is sleeved on the external thread part of the crown body 3, and meanwhile, the elastic rubber pad 40 can also prevent impurities in part of the oral cavity from entering the gap between the crown body 3 and the crown head 4, so that the cleanliness of the implant in daily use can be improved.
In order to buffer the acting force of the crown head 4 in the chewing process, in the embodiment, the elastic pad 6 is arranged between the crown head 4 and the crown body 3, and meanwhile, the fastening screw 30 can be well protected by the elastic pad 6, so that the situation that the fastening screw 30 is polluted due to the fact that oral impurities enter the fastening screw 30 is reduced.
In the rotation process of the fastening screw 30, a torsion force may be generated on the crown body 3 to make the crown body 3 and the abutment 2 relatively rotate, thereby causing the installation position of the crown body 3 to be inaccurate, therefore, in order to solve the problem, in the embodiment, the top of the abutment 2 is annularly provided with a plurality of limit blocks 20, the bottom of the crown body 3 is provided with a limit groove 21 corresponding to the limit block 20, when the crown body 3 is installed by a therapist, the crown body 3 can be installed by aligning the position where the limit block 20 is embedded into the limit groove 21, thereby improving the installation accuracy of the crown body 3.
