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 underpart angular thread has promoted its self tapping, make implantation process more efficient and convenient, the mechanical strength that the trapezoidal thread at its middle part or rectangular thread have improved structural entity, has improved stress performance, the success rate that has greatly improved plantation, has effectively promoted clinical application effect;
3, by unique structure, formed interior concaved circular cambered surface, greatly shortened the restore cycle, and this artificial structure is closely connected with firm with alveolar bone, displacement is difficult for getting loose;
4, implantation piece outer surface of upper is with circumferential annular groove, increased the contact area with 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;
5, its implantation piece itself adopts porous tantalum product, well met its mechanical property, improved 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.

The specific embodiment
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 steady type Dental Implant, it is comprised 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 lower side 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 inner groovy 3 lower side; The top 5 of its retention means 2 is spindle shape, concaved circular cambered surface 7 in forming between its maximum gauge place 6 and implantation piece 1 upper surface; 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 9 of 95 ° with tooth form angle, and bottom appearance is the angular thread 10 of 60 ° with tooth form angle, and the axial length ratio of this trapezoidal thread 9 and angular thread 10 equals 1.4; The top 5 of its retention means 2 adopts medical titanium alloy one-body molded with the threaded rod of its underpart 4, and further by the top of this retention means 25 and corona corresponding matching, has realized artificial tooth implantation.
In this example, concaved circular cambered surface 7 in forming between the upper surface of implantation piece 1 and the maximum gauge place 6 of retention means 2, such structure makes to have formed an annular healing district between retention means 2 outer surfaces and implantation piece 1 upper surface.This design forming the matching surface of its structure and oral cavity bone bed.On this matching surface, the synosteosis that the growth of bone bed and artificial growth dentification are firm, thus canine implant is fixed, promote it to survive.The osteogenesis that is designed in healing district provides larger spatial accommodation, has accelerated osteogenesis process, has also accelerated post-operative recovery process.Meanwhile, because the associativity of this structure and human body bone is better, human body sensory is more naturally comfortable, and foreign body sensation also reduces greatly, and resistance to chewiness is enhanced.Cannelure 8 has the effect that starts the growth of bone bed, holds area of new bone equally.Meanwhile, due to its loop configuration, the area of new bone of shaping can also play snap action to canine implant, makes its maintenance more stable, is difficult for occurring loosening.In addition, 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 guarantee good mechanical property simultaneously, reaches optimum implantation effect, improved and has been implanted to power, promoted postoperative effective utilization.
