The head of above-mentioned retention means and the threaded rod of its underpart one-body molded.After the head of this retention means being fixed on retention sleeve in application, namely at this retention sleeve outer Corresponding matching, corona can being installed, and then achieving artificial tooth implantation.
Stepped hole is set in above-mentioned retention sleeve, spacing with what realize retention means head, thus ensure that the two reliability connected.
The quantity of above-mentioned annular groove is 1 to 3.Above-mentioned annular groove is more than or equal to 0.2mm apart from the distance of above-mentioned implant member upper surface, is less than or equal to 0.3mm.
The thread form angle of the trapezoidal thread in the middle part of above-mentioned implant member is more than or equal to 90 °, is less than or equal to 135 °; The thread form angle of above-mentioned implant member bottom angular thread is more than or equal to 30 °, is less than or equal to 80 °.
The axial length ratio of the trapezoidal thread on above-mentioned implant member 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, implant member adopts porous tantalum product, well meets mechanical property requirements, improves stress performance, considerably increase biocompatibility simultaneously, improve service life and implant comfort level, adding the stability after implantation and anti-rotation performance, substantially increase the success rate of plantation;
3, implant member outer surface of upper is with circumferential annular groove, 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 prosthese, be conducive to the combination of assembly and human body, promote comfort;
4, plant trapezoidal thread or rectangular thread in the middle part of tooth body and improve the mechanical strength of structure, improve stress performance, bottom angular thread improves self tapping, implants more efficient and convenient, substantially increases the success rate of plantation, effectively improve clinical application effect;
5, stopper slot is set by the top at implant member, and Corresponding matching installs retention sleeve in this stopper slot, afterwards the threaded rod of retention means bottom is connected with implant member through after this retention sleeve again, thus strengthen the retention means support force be subject in the horizontal direction, and the probability greatly reducing its effect suffering horizontal lateral force and rupture.

Detailed description of the invention
Be below this utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.
Embodiment 1
As shown in Figures 1 to 3: a kind of Dental Implant external member, it is made up of implant member 1, retention means 2 and retention sleeve 3; Its implant member 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 implant member 1 inside is provided with groove 4, and groove 4 side is provided with regular screw threads; The top of this implant member 1 is also provided with the stopper slot 5 be communicated with groove 4, and in this stopper slot 5, Corresponding matching installs retention sleeve 3, is set to stepped hole in this retention sleeve 3; The bottom of its retention means 2 is threaded rod 6, after this threaded rod 6 passes retention sleeve 3, with the regular screw threads corresponding matching of implant member 1 interior grooves 4 side; Its implant member 1 outer surface of upper is provided with the annular groove 7 of two circumference distributions, and these two annular grooves 7 equal 0.25mm apart from the maximum distance of implant member 1 upper surface; Middle part appearance equals the trapezoidal thread 8 of 95 ° with thread form angle, lower external equals the angular thread 9 of 50 ° with thread form angle, and the axial length ratio of trapezoidal thread 8 and angular thread 9 equals 1.4; The head of its retention means 2 and the threaded rod 6 of its underpart adopt medical titanium alloy one-body molded, and by the head of retention means 2 and corona corresponding matching, namely achieve artificial tooth and implant.
In clinical practice, in stopper slot 5, Corresponding matching installs retention sleeve, afterwards the threaded rod 6 of retention means 2 bottom is connected with the regular screw threads of groove 4 side of implant member 1 through after this retention sleeve 3 again, thus strengthen retention means 2 support force be subject in the horizontal direction, and the probability greatly reducing its effect suffering horizontal lateral force and rupture; In addition, cannelure 8 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 this canine implant prosthese, makes its maintenance more stable, not easily occurs to loosen.
