Technical field
This utility model relates to oral cavity manual tooth planting, particularly relates to a kind of pointedly to plant dental assembly.
Background technology
As the abiotic assembly that outside artificial implants, be applied to the plantation assembly in the manual tooth planting of oral cavity, the embeddability after it is implanted and between body bone tissue and connectivity are the principal elements affecting its result of use.At present, the plantation assembly in application includes the compositions such as implant member, retention means and corona from bottom to top.It mostly exists, and self tapping is poor, implantation difficulty; Biocompatibility is poor, is connected defective tightness with body bone tissue, easy loose or dislocation etc. defect.Though Separate designs can realize implanting fast, and the effect be firmly connected with body bone tissue, but still there is the effect of easily suffering horizontal lateral force and rupture, mechanical property and the lower problem of reliability.
Utility model content
The purpose of this utility model is to provide a kind of and pointedly plants dental assembly, and it is not only implanted conveniently, it is closely reliable to connect, and has good biocompatibility and mechanical property concurrently.
The purpose of this utility model is achieved in that
One is pointed plants dental assembly, it is characterized in that: it is made up of implant member, retention means and retention sleeve; Described implant member adopts porous tantalum product, and its porosity is 60% ~ 70%; Described implant member inside is provided with groove, and groove side is provided with gas thread; The top of described implant member is also provided with the stopper slot be communicated with described groove, and in stopper slot, Corresponding matching installs described retention sleeve; The bottom of described retention means is threaded rod, after threaded rod passes described retention sleeve, with the gas thread corresponding matching of described implant member interior grooves side; Described implant member outer surface of upper is provided with the annular groove of circumference distribution, and middle part appearance is with trapezoidal thread or rectangular thread, and bottom is set to bullet-headed.
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 gas thread that above-mentioned groove side is arranged is 55 °, to be realized implant member be connected with the sealing of retention means by arranging of gas thread.
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 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 °.
This utility model has following beneficial effect:
1, in its overall structure, implant member and retention means are connected by gas thread, easily produce self-locking, and sealing and good stress performance avoid impurity and enter in screw thread, and simplify the structure;
2, by Corresponding matching in stopper slot, retention sleeve is installed, afterwards the threaded rod of retention means bottom is connected with implant member through after 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;
3, implant member is porous tantalum product, Bone Ingrowth can be made and structure of growing in being formed, well meet mechanical property requirements, improve 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;
4, 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; In the middle part of implant member, trapezoidal thread or rectangular thread improve the mechanical strength of structure, improve stress performance; , implant member bottom is bullet-headed, be similar to the sharp structure of screw termination, improve self tapping, implant more efficient and convenient, this implant member is firmly hammered in body bone tissue, further increase stable connection, substantially increase the success rate of plantation, effectively improve clinical application effect.

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: one is pointed plants dental assembly, and 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; Implant member 1 inside is provided with groove 4, and groove 4 side is provided with the gas thread that thread form angle is 55 °; 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, and this threaded rod 6, through after retention sleeve 3, is the gas thread corresponding matching of 55 ° with the thread form angle of implant member 1 interior grooves 4 side; Its implant member 1 outer surface of upper is provided with the annular groove 9 of two circumference distributions, and these two annular grooves 9 equal 0.25mm apart from the maximum distance of implant member 1 upper surface; In the middle part of its implant member 1, appearance equals the trapezoidal thread 8 of 95 ° with thread form angle, and bottom 7 is set to smooth bullet-headed; The head of its retention means 2 and the threaded rod 6 of its underpart adopt medical titanium alloy one-body molded, and after the head of retention means 2 is seated in retention sleeve 3, then at this retention sleeve 3 outer Corresponding matching, corona is installed, and then achieve artificial tooth implantation.
In clinical practice, in stopper slot 5, Corresponding matching installs retention sleeve 3, afterwards the threaded rod 6 of retention means 2 bottom is connected with the gas thread 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.Its cannelure 9 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 complex implanted false teeth prosthese, makes its maintenance more stable, not easily occurs to loosen.
