This utility model has following beneficial effect:
1, its overall structure is connected by threaded engagement, easily produces self-locking, good stress performance, and simplifies the structure;
2, its underpart angular thread improves self tapping, and implantation process is more efficient and convenient, substantially increases the success rate of plantation, improves clinical application effect;
3, define interior concaved circular cambered surface by unique structure, substantially reduce the restore cycle, and by this artificial structure and alveolar bone compact siro spinning technology and fastening, not easily get loose displacement;
4, implantation piece adopts porous tantalum product, not only meets mechanical property requirements, improves stress performance, also greatly increases biocompatibility, improve service life and implant comfort level, adding the stability after implantation and anti-rotation performance, substantially increase the success rate of plantation;
5, implantation piece outer surface of upper is with the annular groove of circumferential distribution, increases the contact area with human body, for osteogenesis provides certain space, be conducive to sclerotin and grow healing fast, and alleviate the deadweight of Dental Implant assembly, be conducive to the combination of assembly and human body, promote comfort;
6, the setting of through hole is convenient to that biotic factor etc. is increased the material of planting tooth steadiness and is incorporated into the sclerotin weakness such as bottom, adds the stability of connection, makes its and bony fusion faster, better;
7, adopt and extension spring one end is fixed on the alveolar bone of bottom, other end noose is connected on threaded rod, achieve and the alveolar bone of bottom close contact all the time, also continue to apply active force to its overall structure simultaneously, to resist outside alternating force effect in real time, in use, if loosened because of external force, then extension spring makes it again keep close contact by elastic force, and then ensure that fixed effect.

Detailed description of the invention
Below by embodiment, this utility model is specifically described; what be necessary to herein means out is that 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 according to foregoing to this utility model.
Embodiment: as Figure 1-3, a kind of dental implant system, it is made up of implantation piece 1, retention means 2 and extension spring 9; Its implantation piece 1 adopts porous tantalum product, and its porosity is 60% ~ 70%, and this porous tantalum product specifically can adopt method preparation as described in patent 201110296515.7; This implantation piece 1 inside is provided with the through hole 3 run through up and down, and through hole 3 inner surface is provided with regular screw threads, and in this through hole 3, bottom is placed with extension spring 9; The bottom of its retention means 2 is threaded rod 4, and this threaded rod 4 is connected with one end noose of extension spring 9, and with the regular screw threads corresponding matching of through hole 3 inner surface; The top 5 of its retention means 2 is fusiform, concaved circular cambered surface 7 in being formed between its maximum gauge place 6 and implantation piece 1 upper surface; Its implantation piece 1 lower external face is the angular thread 10 of 60 ° with thread form angle; Its implantation piece 1 outer surface of upper is provided with the annular groove 8 of two circumference distributions, and this annular groove 8 equals 0.3mm apart from the maximum distance of implantation piece 1 upper surface; The top 5 of its retention means 2 adopts medical titanium alloy one-body molded with the threaded rod 4 of its underpart, and further by the top 5 of this retention means 2 and corona corresponding matching, namely achieves artificial tooth and implant.
In clinical practice, extension spring 9 one end is fixed on bottom alveolar bone, other end noose is connected on threaded rod 4 to continue to apply elastic force to retention means 2, ensure that retention means 2 all the time with implantation piece 1 close contact, active force is applied to structure entirety simultaneously, make itself and bottom alveolar bone close contact all the time; If because external force makes connection loosing during use, then extension spring 9 makes it again keep close contact by elastic force, and then ensure that fixed effect.The setting of interior concaved circular cambered surface 7, make to define an annular healing district between retention means 2 outer surface and implantation piece 1 upper surface, human bone cell can be rapidly to healing district growth inside, until filled, its bone tissue growth is obviously accelerated, and the restore cycle shortens greatly.And due to bone cell growth fill annular healing district, which form to Dental Implant naturally surround and fastening, it is rooted among alveolar bone firmly, and not easily get loose displacement.Meanwhile, annular groove 8 also has the effect starting the growth of bone bed, hold area of new bone, and due to its loop configuration, the area of new bone of shaping can also play snap action to dental implant system, makes its maintenance more stable, not easily occurs to loosen.
