As further improvement, the top of above-mentioned retention means and the threaded rod of its underpart one-body molded.This arrangement simplifies structure, be convenient to manufacture.By the top of this retention means and corona corresponding matching in application, namely achieve artificial tooth and implant.
As further improvement, in the middle part of above-mentioned implantation piece, the thread form angle of the trapezoidal thread of appearance is more than or equal to 90 °, is less than or equal to 135 °.
As further improvement, the thread form angle of the angular thread of above-mentioned implantation piece lower external is more than or equal to 30 °, is less than or equal to 80 °.
As further improvement, the axial length ratio of the apparent trapezoidal thread of above-mentioned implantation piece and angular thread is more than or equal to 1.4, is less than or equal to 1.5.
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, make implantation process more efficient and convenient, the trapezoidal thread in the middle part of it or rectangular thread improve the mechanical strength of structure entirety, improve stress performance, substantially increase the success rate of plantation, effectively improve 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, its implantation piece itself adopts porous tantalum product, well meet its mechanical property, improve stress performance, also greatly increases its biocompatibility simultaneously, improve service life and implant comfort level, add the stability after the implantation of this artificial prosthesis and anti-rotation performance, substantially increase the success rate of plantation;
5, by the setting of through hole, other materials of planting tooth steadiness with increase such as bone grafting material, biotic factor are convenient to introduce, be evenly distributed on the sclerotin weakness such as structure bottom, and add the stability that this structure is connected with sclerotin, make itself and bony fusion faster, better;
6, adopt and extension spring one end is fixed on the alveolar bone of bottom, other end noose is connected on threaded rod, and achieve the alveolar bone close contact all the time of itself and bottom, also achieve simultaneously and continue to apply active force to its overall structure, to resist the effect of outside alternating force 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 shown in Figure 1-2, a kind of Dental Implant assembly, it is made up of implantation piece 1, retention means 2 and extension spring 10; 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 10; 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 10, 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; In the middle part of its implantation piece 1, appearance is the trapezoidal thread 9 of 95 ° with thread form angle, and lower external face is the angular thread 8 of 60 ° with thread form angle, and the axial length ratio of this trapezoidal thread 9 and angular thread 8 equals 1.4; 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 10 one end is fixed on the bottom of 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, simultaneously to the effect of the overall applying power of its structure, make the bottom close contact all the time of itself and alveolar bone; If because external force makes structure, entirety loosens during use, then extension spring 10 makes it again keep close contact by elastic force, and then ensure that fixed effect.In addition, the setting of interior concaved circular cambered surface 7, makes 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.Because bone cell growth fills the healing district of annular, it naturally form the encirclement of Dental Implant and fastening, and it is rooted among alveolar bone firmly, and not easily get loose displacement.
