Embodiment Construction

[0026] Such as Figure 1 to Figure 3 As shown, it is a self-tapping dental implant according to the present invention, which mainly includes a body 1 .

[0027] The main body 1 is arranged adjacent to the neck 11 , the body 12 , the root 13 and the bottom 14 sequentially from top to bottom. The outer surface of the body 1 is treated by sandblasting and acid etching to form an auxiliary layer that enhances the performance of bone integration.

[0028] The neck 11 is a cylinder, and the outer surface of the neck 11 is provided with four circles of circular grooves. A circle of chamfers 112 is provided on the edge of the end face of the neck 11. The depth of the chamfers 112 is 0.1 mm, and the width of the chamfers 112 is 0.25 mm. .

[0029] The body 12 is a first conical thread segment and the root 13 is a second conical thread segment. Both the thread taper of the body 12 and the root 13 are Morse tapers, the thread taper of the body 12 is 1°-2°, and the thread taper of the ...

Abstract

The invention provides a self-tapping dental implant. The self-tapping dental implant comprises a body, wherein the body is successively provided with a neck part, a body part, a root and a bottom from top to bottom in an adjoining manner; the neck part is a cylinder; the outer surface of the neck part is provided with a four-ring circular groove; the body part is a first tapered thread section; the root is a second tapered thread section; the thread tapers of the first tapered thread section and the second tapered thread section are different; three slant self-tapping cutting grooves are uniformly distributed in the periphery of the outer surface of the root; the bottom is a sphere; an open inner cavity is vertically formed in the radial middle part of the body; the inner cavity is successively provided with reverse tapered bores, regular polygon bores, cylindrical bores and inner threaded bores from top to bottom in an adjoining manner; the diameter of each cylindrical bore is the same as that of an inscribed circle of each regular polygon bore. The self-tapping dental implant has the function of platform transferring; due to the design of double tapers and arrangement of cutting grooves, implanting operation can be performed more easily, the initial stability of tooth implantation is improved, and the bone loss is reduced to the maximum extent. The matching of inner conical surfaces and the base station achieves the sealing effect to prevent micro leakage.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a self-tapping dental implant used for oral implantation. Background technique [0002] Due to the reliability and comfort of dental implant restoration compared with traditional fixed bridge and removable denture restoration, people pay more and more attention to its research and use. According to statistics from authoritative organizations, about 10% of people will choose dental implant technology to restore their teeth in their lifetime. In developed countries, nearly 50% of patients with dentition defects and edentulousness will choose dental implant technology for restoration, so dental implants have broad prospects in the field of oral treatment. [0003] However, due to the individual differences in the oral conditions of patients, the existing implant system has certain limitations. The initial stability of dental implants after implant restoration is not good. According...
