[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. 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.

[0035] 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.

[0036] 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.

[0037] According to a first embodiment of the present invention, there is provided a dental implant assembly:

[0038] A dental implant assembly comprises: a crown prosthesis A; a base 2 for being mounted on the implant; a base connecting portion 201 connected to the crown prosthesis A is arranged on the base 2; a fastener 3 is used to connect the base connecting portion 201 and the crown prosthesis A; wherein the crown prosthesis A comprises: a crown-shaped main structure 1; 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 the mounting fastener 3; the second cavity 102 is used to be sleeved on the base 2; the inner cavity shape of the second cavity 102 is a first geometric shape; the outer side of the base connecting portion 201 is provided with an anti-rotation structure 202 for being embedded and matched with the second cavity 102, and the outer shape of the anti-rotation structure 202 is a first geometric shape; the first geometric shape is a spiral prism.

[0039] The present application provides a technical solution for a dental implant component. In the technical solution, a first cavity and a second cavity that are interconnected are provided on the crown-shaped main structure, and the crown prosthesis is connected to the base connection part of the base through the second cavity, and then the crown prosthesis and the base are fastened together by fasteners; further, since the second cavity and the anti-rotation structure are both of the first geometric shape, and the first geometric shape is a spiral prism, the crown prosthesis needs to be rotated at a certain angle during the connection with the base to achieve the purpose of installing the crown prosthesis and the base; this innovation changes the installation path of the crown prosthesis, and compared with the direct insertion type in the prior art, it can further increase the effect of the crown prosthesis falling off and improve the stability of the crown prosthesis installation. The technical solution provided by the present application can effectively improve the stability of the connection between the crown prosthesis and the base, increase the difficulty of the crown prosthesis falling off, and extend the service life of the crown prosthesis.

[0040] It should be added that the first geometric shape is a spiral prism, so that when the crown prosthesis is installed on the base, the crown prosthesis will not rotate relative to the base, so that the crown-shaped main structure has a certain anti-rotation effect relative to the base; further, an external fastener penetrates the first cavity and the second cavity to achieve a fastened connection between the crown-shaped main structure and the base.

[0041] It should be noted that the internal structure of the dental crown prosthesis is simple, and a small volume and simple structure can achieve the repair effect of connecting the dental crown prosthesis with the base. The technical solution provided by this application can improve the convenience of installing the dental crown prosthesis, simplify the structure inside the dental crown prosthesis, reduce the volume of the dental crown, and improve the applicability of installing the dental crown prosthesis.

[0042] It should be noted that when the first geometric shape is one of a prism, an elliptical cylinder, and a notched cylinder, the second cavity cannot rotate relative to the base after being mounted on the base, thereby achieving an anti-rotation effect for a single crown prosthesis.

[0043] It should be noted that when the first geometric shape is a spiral prism, the dental crown prosthesis needs to be rotated at a certain angle during the process of being installed on the base, so as to meet different installation requirements of the dental crown prosthesis.

[0044] It should be noted that in this technical solution, an anti-rotation structure is provided on the base, and the external shape of the anti-rotation structure is also the first geometric shape, and the anti-rotation structure can be embedded in the second cavity and abutted against each other; thereby achieving the technical effect of the anti-rotation of the crown prosthesis while combining the base and the crown prosthesis. The technical solution provided by this application can achieve the direct connection of the crown prosthesis with the base and have an anti-rotation effect.

[0045] It should be noted that the crown prosthesis and the abutment are quickly connected by fasteners.

[0046] To explain in detail, in an embodiment of the present invention, the crown prosthesis A also includes: a limiting hole structure 103 arranged between the first cavity 101 and the second cavity 102, and the limiting hole structure 103 is used to limit the displacement direction of the fastener 3 and the crown-shaped main structure 1; the limiting hole structure 103 is provided with a conical surface structure 104 on the side facing the first cavity 101, and the conical surface structure 104 is used to abut against the fastener 3 to transmit the fastening force of the fastener 3 to the main body of the crown-shaped main structure 1.

[0047] It should be noted that the fixing and installation of the crown prosthesis by the fastener is achieved through the limiting hole structure.

[0048] 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.

[0049] Specifically, in the embodiment of the present invention, the dental crown prosthesis A further comprises: an anti-slip structure 105 provided on the contact surface between the conical structure 104 and the fastener 3, and the surface roughness Ra of the anti-slip structure is 30-300.

[0050] 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.

[0051] To explain specifically, in an embodiment of the present invention, the fastener 3 is connected to the base connection portion 201 via a threaded structure; preferably, 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 surface structure 104.

[0052] 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.

[0053] Specifically, in the embodiment of the present invention, the base 2 is a straight base or an angled composite base.

[0054] 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.

[0055] 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.

[0056] Specifically, in an embodiment of the present invention, the first geometric shape is a spiral prism, so that during the connection between the crown prosthesis A and the base 2, the crown prosthesis A and the base 2 need to be rotated, and the direction of rotation is associated with the spiral direction of the spiral prism.

[0057] Specifically, in the embodiment of the present invention, the fastener 3 is a screw, and the direction of rotation of the thread of the fastener 3 is the same as the direction of the spiral prism; the bottom of the anti-rotation structure 202 and the bottom of the second cavity 102 are connected by interference fit.

[0058] It should be noted that by designing the first geometric shape into a spiral prism, the crown prosthesis and the base have a tendency to move and install in a single direction, and the crown prosthesis is then fastened by a fastener. Since the fastener thread direction is the same as the spiral direction of the spiral prism, the fastener and the crown prosthesis together form a self-tightening effect on the base, thereby improving the durability of the crown prosthesis installed using this method.

[0059] It should be noted that in the prior art, the crown is generally installed by fastening the base to the base, and then installing the crown on the base by bonding, but this process requires two installation steps. Research has found that there is no technical solution for directly connecting the crown prosthesis to the base in the prior art. The reason is that the crown prosthesis is directly connected to the base through fasteners. Due to the complex and changeable oral environment and the relatively high utilization rate of teeth, there is a problem of loosening of the fasteners directly connected, which in turn causes the crown prosthesis to loosen, affecting the use time of the crown prosthesis.

[0060] In order to make the connection between the crown prosthesis and the abutment more tightly, the present application designs the cooperating second cavity and the anti-rotation structure into a unified first geometric shape, namely a spiral prism, so that the crown prosthesis needs to be rotated to a certain extent during the installation process; based on this, the crown abutment can work together with the fasteners on the same abutment to achieve a self-tightening effect.

[0061] It should be further added that the helix angle of the spiral prism is greater than the helix angle of the fastener thread, that is, the directions of the forces acting on the crown prosthesis and the fastener by the abutment are different, further improving the self-tightening effect between the crown prosthesis and the fastener.

[0062] According to a second embodiment of the present invention, a method for connecting a dental implant component is provided:

[0063] A connection method based on the above-mentioned dental implant component, the connection method comprising the following steps: fixing the base 2; adjusting the angle relationship between the crown prosthesis A and the base 2 according to the installation posture data of the crown prosthesis A; aligning the second cavity 102 of the crown prosthesis A with the base connection part 201, and installing the crown prosthesis A on the base connection part 201, during which the crown prosthesis A is rotated so that the crown prosthesis A reaches a first predetermined installation position; extending a fastener 3 from the first cavity 101 through the second cavity 102 into the base connection part 201 for fastening connection; tightening the fastener 3, and the crown prosthesis A is rotated from the first predetermined installation position to the final predetermined installation position under the action of the fastener 3.

[0064] The present application also provides a connection method for the above-mentioned dental implant component, which first installs the crown prosthesis to a first predetermined installation position by rotating the crown prosthesis; since there is an interference fit between the crown prosthesis and the base, the crown prosthesis can be installed to the final predetermined installation position through the action of the fastener, thereby achieving proper connection of the dental implant component. At the same time, due to the interference fit, the bottom of the base and the bottom of the crown prosthesis are more closely connected, which has a certain sealing and protective effect on the inside of the crown prosthesis, thereby increasing the service life of the dental implant.

[0065] Specifically, in the embodiment of the present invention, the bottom of the anti-rotation structure 202 of the base connection portion 201 is connected with the bottom of the second cavity 102 by interference fit, so that there is a certain sealing effect between the base 2 and the crown prosthesis A.

[0066] According to a third embodiment of the present invention, a method for manufacturing a dental implant component is provided:

[0067] A manufacturing method of the above-mentioned dental implant component, the manufacturing method comprising: obtaining oral cavity model data, the oral cavity model data is the oral cavity model data after the base is installed, and the oral cavity model data includes the posture data of the base 2 and the upper and lower teeth occlusal surface data; making an oral cavity model according to the oral cavity model data; drawing and generating the three-dimensional data of the periphery of the crown prosthesis by combining the oral cavity model and the upper and lower teeth occlusal surface data; designing the internal structure data of the crown prosthesis according to the posture data of the base 2, and the internal structure data of the crown prosthesis includes the first cavity 101 and the posture data of the second cavity 102; the internal structure data of the crown prosthesis and the three-dimensional data of the periphery of the crown prosthesis constitute the crown prosthesis model data; the crown prosthesis is generated by cutting according to the crown prosthesis model data; wherein the base is a prefabricated standard part, and the base includes an anti-rotation structure 202; the external shape of the anti-rotation structure 202 and the inner shape of the second cavity are both preset first geometric shapes, the first geometric shape is a spiral prism, and the bottom of the anti-rotation structure 202 is connected with the bottom of the second cavity 102 by interference fit.
