Embodiment 1

[0035] figure 1It is the front view of the one-piece artificial dental implant of the present invention; figure 2 It is a perspective view of a one-piece artificial tooth implant of the present invention; image 3 It is a top view of the one-piece artificial dental implant of the present invention; Figure 4 It is the bottom view of the one-piece artificial dental implant of the present invention; Figure 5 It is a schematic diagram of the thread structure of a one-piece artificial dental implant of the present invention.

[0036] This embodiment discloses a one-piece artificial tooth implant, such as figure 1 and figure 2 As shown, the one-piece artificial dental implant includes an integral and sequentially coaxially connected for implanting into the bone, a rough-surfaced implant segment 3, a smooth-surfaced transgingival segment 2, and an abutment for connecting with the crown 1. The one-piece artificial dental implant is integrally formed with pure titanium metal. ...

Embodiment 2

[0043] Figure 6 It is a perspective view of a one-piece artificial dental implant in Example 2 of the present invention; Figure 7 It is the front view of the one-piece artificial dental implant in Example 2 of the present invention.

[0044] This embodiment discloses a one-piece artificial tooth implant which is basically the same as Embodiment 1, except that the self-tapping grooves are two helical self-tapping grooves 36, such as Figure 6 and Figure 7 As shown, the helical direction of the helical self-tapping groove 36 and the helical direction of the thread are both right-handed, and the thread lead angle of the helical self-tapping groove 36 is greater than that of the thread. The spiral self-tapping groove 36 is composed of two arc surfaces, and the junction of the two arc surfaces is tangentially connected.

Abstract

The present invention provides a one-piece artificial tooth implant and its implanting method. The one-piece artificial tooth implant comprises an implant section, a gingival section and an abutment that are sequentially connected coaxially in one piece, and the surface of the implant section is provided with There are threads, the end of the implant segment away from the gingival segment is a truncated cone, the small diameter end of the truncated cone is an arc surface, the radius of the arc surface is R / 2, and the R / 2 is 1mm- 2mm; the truncated cone is provided with a self-tapping groove, and the self-tapping groove is a vertical self-tapping groove or a spiral self-tapping groove. The invention also discloses a method for planting a one-piece artificial tooth implant. The invention overcomes many shortcomings of the prior art, and can increase the self-tapping performance of the implant while ensuring the structural strength.

Description

technical field [0001] The invention relates to the technical field of oral medical instruments, in particular to a one-piece artificial tooth implant and its implantation method. Background technique [0002] The implants used in "artificial implants" can be divided into one-piece and multi-piece according to the type. Among them, the multi-segment implant is usually composed of implant, abutment and central screw, and the implant and abutment are fixed by the central screw. The implantation of the multi-segment implant requires two operations, which not only prolongs the treatment and healing time , also increased the pain of the patient. Moreover, the second implant operation cannot be guaranteed to be completely successful, which puts a lot of pressure on both the patient and the doctor. One-piece implants can achieve one-time implantation of artificial teeth, but one-piece implants are mostly used in anterior tooth implants. The alveolar bone of anterior teeth is rela...
