Description
Technical field
This utility model relates to oral cavity manual tooth planting, particularly relates to a kind of dentistry plantation external member.
Background technology
Dental plantation is the best method of repairing mouth inner teeth gear disappearance at present, applies more and more widely because its good effect obtains.The dentistry plantation external member used in plantation mostly includes the ingredients such as implant member, retention means and corona.Although diversity is comparatively large between each design existing, wherein all there are some defects, such as plantation external member self tapping is poor, implant procedure is complicated; Defective tightness is connected, easy loose or dislocation with body bone tissue; Mechanical property and biocompatibility poor; The support force that the retention means exposing to dental surface is subject in the horizontal direction is lower, and easily suffer the effect of horizontal lateral force and rupture, reliability is lower; The materials such as the soft tissue chip produced in implantation process are not easily discharged, and stay in the body to cause to addle, infect etc., and these defects directly affects its clinical application effect.
Utility model content
The purpose of this utility model is to provide a kind of dentistry to plant external member, and this dentistry plantation external member self tapping is good, it is efficient and convenient to implant, be connected closely with human body, be beneficial to foreign body discharges, and has good biocompatibility and mechanical property concurrently.
The purpose of this utility model is achieved in that
A kind of dentistry plantation external member, 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 regular screw threads; 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 regular screw threads corresponding matching of described implant member interior grooves side; In the middle part of described implant member, appearance is with trapezoidal thread or rectangular thread, and lower external is with angular thread; Described implant member lower end is also provided with axially extended chip removal flute.
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 chip removal flute is 2 ~ 3, is uniformly distributed along implant member lower external.
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, in the middle part of implant member, trapezoidal thread or rectangular thread improve the mechanical strength of structure, improve stress performance, and bottom angular thread improves self tapping, implant more efficient and convenient, substantially increase the success rate of plantation, effectively improve clinical application effect;
4, 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;
5, the chip removal flute set up serves foreign bodies such as removing in implantation process the soft tissue chip that produces, avoids it to stay in the body causing addling, the effect such as infection, effectively improves 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: a kind of dentistry plantation 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; In the middle part of its implant member 1, appearance equals the trapezoidal thread 8 of 100 ° with thread form angle, and lower external equals the angular thread 9 of 60 ° with thread form angle, and the axial length ratio of trapezoidal thread 8 and angular thread 9 equals 1.5; Its implant member 1 lower end is also provided with an axially extended chip removal flute 7; 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 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, the chip removal flute 7 set up serves foreign bodies such as removing in implantation process the soft tissue chip that produces, avoids it to stay in the body causing addling, the effect such as infection, effectively improves clinical application effect.
