Abstract
The utility model relates to an artifical root of tooth. It comprises retainer (1), spring (2), checkpost (3) and implantation body parts such as (4), it has realized the grafting mating reaction of each part when the installation through setting up parts such as inserted bar, spring and checkposts in special position, and then has realized that the connection of the implantation body and retainer is fixed, and can not produce the rotation, and it combines firmly reliably. In addition, trapezoidal thread or rectangular thread that body middle part outward appearance set up are implanted to it, when guaranteeing its structural mechanics intensity, increased its with the gum in the area of contact of bone tissue, and through the growing into of bone tissue, and make in the bone tissue is embedded into the screw gap, further increased its connection stability, and the implantation body lower part shape of warhead shape appears for the nail, and exterior gradient is great and slick and sly, and the resistance that receives during the implantation is less, has made things convenient for to implant the operation.
Description
Technical field
This utility model relates to canine implant, particularly relates to a kind of artificial tooth root.
Background technology
Traditional Dental Implant mostly includes the parts such as artificial tooth root and artificial tooth.And at present, in the artificial tooth root of existing design, its upper end generally adopts normal thread to be connected for the retainer installing artificial tooth with the implant that lower end is implanted in alveolar bone.In the application because artificial tooth root is usually subject to the effect of alternating force, loosening, rotating and come off very easily appears in this connected mode, and then causes planting the tooth situation such as unsuccessfully, very easily brings secondary injury to patient.In addition, existing artificial tooth root is owing to limitting by its structural design, and the resistance be subject to when implanting is larger, implant procedure difficulty, and the connective stability implanted between rear and body bone tissue is poor, further increases the risk of planting tooth failure, therefore awaits further improvement.
Utility model content
The purpose of this utility model is to provide a kind of artificial tooth root, and this artificial tooth root self structure stable connection, is beneficial to implant procedure, and after implanting with is connected reliably between body bone tissue.
The purpose of this utility model is achieved in that
A kind of artificial tooth root, is characterized in that: it is made up of retainer, spring, clamp and implant; Described retainer bottom is connecting rod; The lower end of described connecting rod is provided with inserted link, and inserted link is positioned at the axis side of connecting rod; Described inserted link is provided with endoporus; The upper end of described implant is inner, be disposed with connecting hole and jack that Corresponding matching installs described connecting rod and described inserted link downwards, and jack is positioned at the axis side of described implant; The axis opposite side described implant corresponding to the described jack of distribution is provided with a groove, and have spring in groove, spring outwards is provided with clamp; Described clamp is engaged in described endoporus and described groove simultaneously; The middle part appearance of described implant is provided with rectangular thread or trapezoidal thread; The lower external of described implant is set to bullet-headed.
In order to make when mounted, more easily clamp can be pushed to spring side, the bottom of above-mentioned inserted link is set to pointed.And further, the outermost upper surface of above-mentioned clamp is provided with an inclined-plane.The bottom pointed by inserted link pushes spring side to clamp, and when clamp and endoporus are at sustained height, spring ejects by clamp, and then implant and retainer is connected and fixed, and can not produce rotation, and it is in conjunction with solid and reliable.
As further optimization, the thread form angle of above-mentioned trapezoidal thread is more than or equal to 90 °, is less than or equal to 135 °.The setting of trapezoidal thread or rectangular thread, while ensureing its structural mechanics intensity, increase the contact area of appearance and dental bed inner bone tissues in the middle part of implant, and growing into by osseous tissue, and make osseous tissue be embedded in thread gaps, further increase its connective stability.
This utility model has following beneficial effect:
This utility model provides a kind of artificial tooth root, it, by the parts such as inserted link, spring and clamp are arranged at privileged sites, achieves all parts grafting mating reaction when mounted, and then achieves being connected and fixed of implant and retainer, and can not rotation be produced, it is in conjunction with solid and reliable.In addition, the trapezoidal thread that in the middle part of its implant, appearance is arranged or rectangular thread, while its structural mechanics intensity of guarantee, increase the contact area of itself and dental bed inner bone tissues, and growing into by osseous tissue, and make osseous tissue be embedded in thread gaps, further increase its connective stability; And bullet shaped implant lower shape is nail shape, appearance gradient is larger and round and smooth, and the resistance be subject to during implantation is less, facilitates implant procedure.

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 artificial tooth root, it is made up of retainer 1, spring 2, clamp 3 and implant 4; Its retainer 1 bottom is connecting rod 5; The lower end of this connecting rod 5 is provided with inserted link 6, and inserted link 6 is positioned at the axis side of connecting rod 5; Inserted link 6 is provided with endoporus 7, and the bottom of inserted link 6 is set to pointed; The upper end of its implant 4 is inner, be disposed with connecting hole 8 and jack 9 that Corresponding matching installs connecting rod 5 and inserted link 6 downwards, and jack 9 is positioned at the axis side of implant 4; The axis opposite side this implant 4 corresponding to distribution jack 9 is provided with a groove 10, have spring 2, be provided with clamp 3 outside spring 2, and the outermost upper surface of clamp 3 is provided with an inclined-plane in groove 10; This clamp 3 is engaged in endoporus 7 and groove 10 simultaneously; The middle part appearance of its implant 4 is provided with the trapezoidal thread 11 that thread form angle equals 100 °; The lower external of its implant 4 is set to bullet-headed 12; The upper end of its retainer 1 is the base station 13 for Matching installation artificial tooth, by the installation of artificial tooth and then the implantation achieving artificial tooth.
When clinical practice is installed, inserted link 6 is passed connecting hole 8 and is plugged in jack 9, by the pointed bottom of inserted link 6, namely clamp 3 is pushed to spring 2 side; When clamp 3 and endoporus 7 are at sustained height, spring 2 ejects by clamp 3, and then implant 4 and retainer 1 is connected and fixed, and can not produce rotation, and it is in conjunction with solid and reliable.After implantation, the trapezoidal thread 11 that in the middle part of implant 4, appearance is arranged, while its structural mechanics intensity of guarantee, increase the contact area of its structure and dental bed inner bone tissues, and growing into by osseous tissue, and make osseous tissue be embedded in thread gaps, further increase its connective stability.
