Description
Technical field
This utility model relates to canine implant, particularly relates to a kind of anti-loosening Dental Implant.
Background technology
Current employing canine implant is the best method of repairing oral cavity inner teeth gear disappearance.But this technology is in clinical practice, still there are some technological deficiencies, such as self tapping is poor, be difficult to implant; Defective tightness is connected with body bone tissue, easy loose or dislocation after implanting; Mechanical property and biocompatibility poor; In implantation or when using, anti-alternating force poor performance, easily occurs loosening and causing graft failure, and then increases the operations such as plantation again, cause significant wastage etc.
Utility model content
For above-mentioned defect, this utility model aims to provide a kind of anti-loosening Dental Implant, and this anti-loosening Dental Implant self tapping is good, convenience is implanted, stress performance is good, connection is reliable, can avoid the interference of alternating force, and has good biocompatibility concurrently.
To achieve these goals, this utility model is by the following technical solutions:
A kind of anti-loosening Dental Implant, is characterized in that: it is made up of implantation piece, retention means and extension spring; Described implantation piece adopts porous tantalum product, and its porosity is 60% ~ 70%; This implantation piece inside is provided with the through hole run through up and down; This through-hole inner surface is provided with regular screw threads, and in this through hole, bottom is placed with extension spring; The bottom of described retention means is threaded rod, and this threaded rod is connected with one end noose of described extension spring, and with the regular screw threads corresponding matching of described through-hole inner surface; The top of described retention means is fusiform, concaved circular cambered surface in being formed between its maximum gauge place and described implantation piece upper surface.
As further improvement, the top of above-mentioned retention means and the threaded rod of its underpart one-body molded.This setting further simplify the structure of retention means, is convenient to manufacture.By the top of this retention means and corona corresponding matching in application, while namely achieving artificial tooth implantation.
As further improvement, above-mentioned implantation piece lower external face is with angular thread.
As further improving, the thread form angle of above-mentioned angular thread is more than or equal to 30 °, is less than or equal to 80 °.
This utility model is by adopting technique scheme, and its overall structure, by being threaded, easily produces self-locking, good stress performance, and simplifies the structure; Its implantation piece appearance bottom angular thread improves its self tapping, makes implantation process more efficient and convenient; Its implantation piece itself adopts porous tantalum product, well meet its mechanical property, improve stress performance, also greatly increases the biocompatibility of this Dental implantion assembly 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; 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 implantation piece bottom, and add the stability that this structure is connected with sclerotin, make itself and bony fusion faster, better; In addition, 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 resist the effect of outside alternating force in real time to its overall structure, 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 anti-loosening Dental Implant, it is made up of implantation piece 1, retention means 2 and extension spring 9; 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 9; 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 9, 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; Its implantation piece 1 lower external face is the angular thread 8 of 60 ° with thread form angle; 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 this example, 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.In addition, in clinical practice, extension spring 9 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 9 makes it again keep close contact by elastic force, and then ensure that fixed effect.
