Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of this application.

[0032] It should be noted that when an element is referred to as being "fixed on" or "set on" another element, it can be directly on the other element or indirectly set on the other element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0035] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the effects and purposes that can be achieved by this application.

[0036] According to a first embodiment of the utility model, a multi-tooth crown prosthesis is provided:

[0037] A multi-tooth crown prosthesis comprises: a crown-shaped main structure 1, two or more of the crown-shaped main structures 1 are connected in an integrated manner; a first cavity 101 arranged at one end of the crown-shaped main structure 1; a second cavity 102 arranged at the other end of the crown-shaped main structure 1; the first cavity 101 and the second cavity 102 are connected, the first cavity 101 is used to set an installation fastener 3, and the second cavity 102 is used to be sleeved on a base 2; a limiting hole structure 103 is arranged between the first cavity 101 and the second cavity 102; the limiting hole structure 103 is used to limit the displacement direction of the fastener 3 and the crown-shaped main structure 1.

[0038] The present application provides a technical solution for a multi-tooth crown prosthesis. In the technical solution, the number of crown-shaped subject structures is 2 or more, that is, the number of crown-shaped main structures is multiple; the multiple crown-shaped main structures are of an integrated design; in each crown-shaped main structure, a first cavity, a second cavity, and a limiting hole structure located between the first cavity and the second cavity are provided, so that the multi-tooth crown prosthesis can be quickly installed with a pre-installed base through fasteners. Furthermore, at least two or more crown-shaped main structures can be connected to the installed base through fasteners, that is, a single multi-tooth crown prosthesis has more than two positioning connection points with the jawbone, so that the single multi-tooth crown prosthesis has an anti-rotation effect, ensuring the stability of the direct connection of the multi-tooth crown prosthesis, without the need to set up a separate anti-rotation interface, and reducing the processing cost of the multi-tooth crown prosthesis; the technical solution provided by the present application can improve the convenience of installation of the multi-tooth crown prosthesis while ensuring the stability of the multi-tooth crown prosthesis directly connected to multiple bases.

[0039] It should be noted that in the prior art, for the scenario of simultaneously implanting multiple adjacent teeth, a Beskid is often first fixed on multiple adjacent abutments that have been installed using fasteners, and then the model data of the Beskid and the oral model data are obtained through reverse molding to produce a multi-tooth crown prosthesis, which is bonded to the Beskid by bonding. Since the abutment requires two steps of fixed connection, the prior art has the problems of slow connection efficiency and increased cost using crown adhesives.

[0040] Specifically, in the embodiment of the utility model, a conical surface structure 104 is provided on the side of the limiting hole structure 103 facing the first cavity 101, and the conical surface structure 104 is used to abut against the fastener 3 to transfer the fastening force of the fastener 3 to the main body of the crown-shaped structure 1.

[0041] It should be noted that the fixing and installation of the crown prosthesis by the fastener is achieved through the limiting hole structure.

[0042] It should be noted that the conical surface structure can adjust the force of the fastener on the crown prosthesis from the direction perpendicular to the abutment mounting surface to the direction scattered to the crown-shaped main structure, thereby reducing the force of the fastening force on the limiting hole structure perpendicular to the abutment mounting surface, thereby avoiding the limiting hole structure from being easily broken.

[0043] Specifically, in the embodiment of the present utility model, it also includes: an anti-slip structure 105 arranged on the contact surface between the conical surface structure 104 and the fastener 3; the surface roughness Ra of the anti-slip structure is 30-300.

[0044] It should be noted that when the fastener is tightened, the anti-slip structure increases the friction between the fastener and the conical surface structure, thereby preventing the fastener from loosening inside the crown prosthesis.

[0045] Specifically, in the embodiment of the present invention, the number of the crown-shaped main structures 1 is 2-14.

[0046] Specifically, in the embodiment of the present utility model, the number of the crown-shaped main structures 1 is 2-4.

[0047] Specifically, in the embodiment of the present utility model, the number of the crown-shaped main structures 1 is 2-3.

[0048] Specifically, in the embodiment of the present invention, the crown-shaped main structure 1 is a crown-shaped main structure 1 with zirconium oxide as a base material.

[0049] According to a second embodiment of the present invention, a dental implant assembly is provided:

[0050] A dental implant assembly comprises: the above-mentioned multi-tooth crown prosthesis A; a base 2 for installation on the implant, the number of the bases 2 being 2 or more; the base 2 being provided with a base connection portion 201 connected to the second cavity 102.

[0051] The present application also provides a technical solution for a dental implant component. In this technical solution, the multi-tooth crown prosthesis is directly connected to multiple bases, which improves the installation efficiency of the crown prosthesis, and at the same time has an anti-rotation effect, which improves the stability of the multi-tooth crown body; that is, while achieving a quick connection between the base and the multi-tooth crown prosthesis, the multi-tooth crown prosthesis also has a technical effect of anti-rotation. The technical solution provided by the present application can achieve direct connection between the crown prosthesis and the base, and has an anti-rotation effect.

[0052] Specifically, in the embodiment of the present utility model, it also includes: a fastener 3 for connecting the base connection part 201 and the multi-tooth crown prosthesis A.

[0053] It should be noted that the crown prosthesis and the abutment are quickly connected by fasteners.

[0054] Specifically, in the embodiment of the present utility model, the fastener 3 is connected to the base connection part 201 through a threaded structure.

[0055] Specifically, in the embodiment of the present utility model, the fastener 3 is a screw, and the bearing surface of the fastener 3 is a conical structure, and the bearing surface of the fastener 3 is used to abut against the conical structure 104 .

[0056] It should be noted that the pressure-bearing surface of the fastener contacts the conical structure to achieve the dispersion of the force, so that the crown prosthesis is subjected to uniform stress from the inside to the outside, thereby increasing the structural strength of the crown prosthesis.

[0057] Specifically, in the embodiment of the present utility model, the base 2 is a straight base or an angle compound base.

[0058] It should be noted that when the implantation position is the chewing big tooth position, the abutment adopts a straight abutment; when the implantation position is the position of the front jaw with a smaller bone, the abutment adopts an angled composite abutment. The application scheme can meet the requirements of rapid positioning and installation of crown prostheses in all positions of the jaw and achieve the effect of anti-rotation.

[0059] It should be noted that, by adopting the present application scheme, there is no need to use adhesives, which reduces the use of adhesives and reduces the cost of dental implants.
