As the improvement to the technical program, the head of above-mentioned retention means is cuboid, and one-body molded with the threaded rod of its underpart.In application, by the head of this rectangular-shaped retention means and corona corresponding matching, in having realized artificial tooth implantation, further increase anti-axial-rotation.
As the improvement to the technical program, the quantity of above-mentioned annular groove is 1 to 3.
As the improvement to the technical program, above-mentioned annular groove is more than or equal to 0.2mm apart from the distance of described implantation piece upper surface, is less than or equal to 0.3mm.
As the improvement to the technical program, the tooth form angle of the trapezoidal thread at above-mentioned implantation piece middle part is more than or equal to 90 °, is less than or equal to 135 °.
As the improvement to the technical program, the tooth form angle of above-mentioned implantation piece bottom angular thread is more than or equal to 30 °, is less than or equal to 80 °.
As the improvement to the technical program, the trapezoidal thread on above-mentioned implantation piece and the axial length of angular thread ratio are more than or equal to 1.4, are less than or equal to 1.5.
The utlity model has following beneficial effect:
1, the regular screw threads that its implantation piece and retention means are arranged by self are connected, and easily produce self-locking, and good stress performance, and the setting of further having saved screw, simplify the structure;
2, its implantation piece itself adopts porous tantalum product, well meet its mechanical property, improve stress performance, also greatly increased its biocompatibility simultaneously, improve service life and implanted comfort level, increase stability and anti-verticity after this artificial prosthesis is implanted, greatly improved the success rate of plantation;
3, implantation piece outer surface of upper is with circumferential annular groove, increased and the contact area of human body, for osteogenesis provides certain space, be conducive to the healing of sclerotin Fast Growth, and the deadweight that has alleviated Dental Implant assembly, is conducive to the combination of assembly and human body, promote comfort;
4, its underpart angular thread has promoted its self tapping, make implantation process more efficient and convenient, the trapezoidal thread at its middle part or rectangular thread have improved the mechanical strength of structural entity, have improved stress performance, the success rate that has greatly improved plantation, has effectively promoted clinical application effect.

Detailed description of the invention
Below by embodiment, this utility model is specifically described; be necessary to be pointed out that at this following examples are only for being further detailed this utility model; can not be interpreted as the restriction to this utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment to this utility model according to foregoing.
Embodiment: as Figure 1-3, a kind of oral cavity implanting tooth, it is made up of implantation piece 1 and retention means 2; Its implantation piece 1 adopts porous tantalum product, and its porosity is 60%～70%, and this porous tantalum product specifically can adopt method preparation described in patent 201110296515.7; This implantation piece 1 inside is provided with groove 3, and groove 3 sides are provided with regular screw threads; The bottom of its retention means 2 is threaded rod 4, the regular screw threads corresponding matching of this threaded rod 4 and implantation piece 1 internal recess 3 sides; Its implantation piece 1 outer surface of upper is provided with two annular grooves 8, and this annular groove 8 equals 0.3mm apart from the maximum distance of implantation piece 1 upper surface; Its implantation piece 1 middle part appearance is the trapezoidal thread 5 of 95 ° with tooth form angle, and bottom appearance is the angular thread 6 of 60 ° with tooth form angle, and the axial length ratio of this trapezoidal thread 5 and angular thread 6 equals 1.4; The head 7 of its retention means 2 is cuboid, and adopts medical titanium alloy one-body molded with the threaded rod 4 of its underpart, and by the head of this rectangular-shaped retention means 27 and corona corresponding matching, has realized artificial tooth implantation.
Trapezoidal thread and rectangular thread have high-intensity feature, are arranged on the bulk strength that contributes to improve structure on implantation piece 1, strengthen its stress performance in use; Its angular thread has good self tapping, and the screw-in while being conducive to implant, simultaneously because its self-locking property is good, can improve the stability of Dental Implant after implanting well, makes retention effect better.Arranging of two kinds of helicitic textures can be learnt from other's strong points to offset one's weaknesses, and makes implantation process conveniently ensure good mechanical property simultaneously, reaches optimum implantation effect, improved and has been implanted to power, promoted postoperative effective utilization.In addition, cannelure 8 has the effect that starts the growth of bone bed, holds area of new bone.Meanwhile, due to its loop configuration, the area of new bone of shaping can also play snap action to this canine implant, makes its maintenance more stable, is difficult for occurring loosening.
