Anatomical root implant, dental restoration having the same, and manufacturing method of dental restoration

Abstract

The invention provides an anatomic root-shaped implant, a dental prosthesis with the same and a method for manufacturing the dental prosthesis. The anatomic root-shaped implant comprises an implant. An abutment accommodating hole is formed in the implant, the thickness of a wall formed by the peripheral wall of the abutment accommodating hole and the periphery of the implant is larger than or equal to the preset minimum wall thickness, a cross section of the abutment accommodating hole is in a non-circular first shape, the top surface of the implant crosses the cross section of the abutment accommodating hole, the area of the first shape is larger than the area of a first circle positioned in the first shape, the circle center of the first circle is the center of the top surface of the implant, and the radius of the first circle is equal to a difference value obtained when the preset minimum wall thickness is subtracted from the minimum distance from the center of the top surface of the implant to the periphery of the implant. According to the technical scheme, the anatomic root-shaped implant, the dental prosthesis and the method have the advantage that the problem of deterioration of strength due to the fact that an anatomic root-shaped implant in the prior art is matched with an existing abutment can be effectively solved.

Description

technical field [0001] The invention relates to the field of stomatology, in particular to an anatomical root-shaped implant, a dental prosthesis with the dental prosthesis, and a method for manufacturing the dental prosthesis. Background technique [0002] There are many geometric shapes of the connection surface between the implant and the abutment in the commercialized implant system at present, and the cross-sections are all circular. [0003] The connection form between the implant and the abutment includes external connection and internal connection. [0004] Among them, the types of external connections can be roughly divided into two types according to their cross-sectional geometric structures: external hexagonal and spline. The external hexagonal structure means that the upper end of the implant protrudes outward into a hexagonal surface. This type of implant is derived from the mechanical structure of the Branemark system connecting and turning the torque wrench....
