Description
Technical field
This utility model relates to manual tooth planting, relates in particular to a kind of anti-loosening Dental Implant.
Background technology
At present, after human oral cavity inner teeth gear disappearance, can adopt dental filling, have a denture made, the multiple means such as plantation reproduces.Wherein, Dental Implant, because it has the advantages such as reliability is high, persistency is strong, has obtained good development in recent years, applies more and more extensively, becomes highly effective medical skill means.
But along with this technology extensive use time, the technical disadvantages of its existence also becomes the technical barrier that needs to be improved and break through gradually, as: existing artificial growth dental structure is comparatively complicated various, and be mostly closed structure design, and mass exchange between body bone tissue, mobility are poor, add other to promote thing once the stationarity weakness such as be difficult at its structure tip after implanting, mechanical property and biocompatibility are poor, thereby are unfavorable for planting fast the realization of tooth process again; Its most self tapping is poor simultaneously, be unfavorable for implanting, and firm not after implanting, be subject to the easy loose or dislocation of alternating force effect, if loosening skew especially when mounted can not recoil to former allocation, can not again tighten thereby cause again significant wastage.
Utility model content
The purpose of this utility model is to provide a kind of anti-loosening Dental Implant, and this anti-loosening Dental Implant is rational in infrastructure, convenient to be implanted, and between body bone tissue, mass exchange is good, can resist the effect of alternating force, has good mechanical property and biocompatibility concurrently.
The purpose of this utility model is achieved in that
A kind of anti-loosening Dental Implant, is characterized in that: it comprises plants tooth body, base station, artificial tooth and Compress Spring; In described base station head, be provided with through hole, in this through hole, have spring, both ends of the spring is arranged with slide block; This slide block is provided with the groove of mounting spring; In described artificial tooth, correspondence is provided with the caulking groove that slide block is installed; In described both ends of planting tooth body, embed and be fixed with ring-type porous tantalum product respectively, its porosity is 60% ~ 70%; Described middle and lower part outer surface of planting tooth body is arranged with axial cutting edge; The outer surface of planting tooth body middle part between this axial cutting edge is also provided with discontinuity screw thread; The described tooth body inside of planting is provided with the perforation running through up and down, and this is planted tooth body bottom end face and is provided with the guiding gutter being communicated with this perforation; Described Compress Spring is fixed by socket is planting tooth body lower outside surface.
The side of above-mentioned perforation middle and upper part is provided with regular screw threads; Above-mentioned base station bottom is threaded rod, and the regular screw threads corresponding matching of this threaded rod and perforation side, middle and upper part, is fixedly connected with the screw thread of realizing the two, to produce self-locking, and good stress performance.
Above-mentioned slide block, is excellently less than the right-angled trapezium body of lower surface area for upper surface area.This slide block also can be set to the object that other sides such as right angle trigonometry body are inclined-plane, or the object of other shapes.
Above-mentioned base station head is cuboid, and one-body molded with its underpart threaded rod, and with artificial tooth corresponding matching, further to increase anti-axial-rotation.
Above-mentioned guiding gutter is horizontal distribution, and can also be set to multiple.Setting up guiding gutter can realize promotion thing introducings such as biotic factors, be evenly distributed on sclerotin weakness such as planting tooth body bottom, to increase the stability being connected with sclerotin, and can also greatly improve the broken end of flesh and blood simultaneously and wait the mobility of materials, make it and be set to porous tantalum product to plant tooth body better compatible.
In this utility model, plant tooth body inside and be provided with the perforation running through up and down, and the guiding gutter being communicated with this perforation, realize sclerotin weakness such as planting tooth body bottom has been introduced, has been evenly distributed on to the promotion things such as biotic factor, increase the stability being connected with sclerotin, and greatly improved the mobility of the materials such as the broken end of flesh and blood; By axial cutting edge, when it is pierced, resistance is less, more convenient, and the misery that patient suffers will reduce greatly; The discontinuity screw thread that it plants tooth external surface, has increased and the contact area of osseous tissue, has realized with alveolar bone and being firmly connected, and further prevented from and rotation.

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 Fig. 1～4: a kind of anti-loosening Dental Implant, it includes plants tooth body 1, base station 2, artificial tooth 10 and Compress Spring 3; In its base station 2 heads, be provided with through hole 11, in this through hole 11, have spring 12, spring 12 two ends are arranged with slide block 6, and this slide block 6 is less than the right-angled trapezium body of lower surface area for upper surface area; This slide block 6 is provided with the groove 15 of mounting spring 12; The interior correspondence of its artificial tooth 10 is provided with the caulking groove 7 that slide block 6 is installed; It is planted in the both ends of tooth body 1 and embeds and be fixed with ring-type porous tantalum product 13 respectively, its porosity is 60% ~ 70%, this ring-type porous tantalum product 13 specifically can adopt described in patent 201110296515.7 method preparation, and specifically processed and embedded by high temperature sintering; The outer surface of planting tooth body 1 middle and lower part is arranged with two axial cutting edges 4; The outer surface of planting tooth body 1 middle part that this axial cutting edge is 4 is also provided with discontinuity screw thread 14; And plant tooth body 1 inside and be provided with the perforation 8 running through up and down, this plants tooth body 1 bottom end face horizontal distribution the guiding gutter 5 being communicated with this perforation 8; Its Compress Spring 3 is fixed by socket is planting tooth body 1 lower outside surface; Its side of boring a hole 8 middle and upper parts is provided with regular screw threads; Its base station 2 bottoms are threaded rod 9, and the regular screw threads corresponding matching of this threaded rod 9 and perforation 8 sides, middle and upper part, is fixedly connected with the self-locking that realizes the two; Its base station 2 heads are cuboid, and adopt medical titanium alloy one-body molded with the threaded rod 9 of its underpart, and while and artificial tooth 10 corresponding matching, have realized the implantation of artificial tooth.
In clinical practice, Compress Spring 13 is fixed on the bottom of alveolar bone, applies active force and be fixed planting tooth body 1 continuing, ensured the close contact all the time of the two; In use, if because external force makes to plant tooth body 1 to be become flexible, Compress Spring 13 makes it again keep close contact by elastic force, and then has ensured fixed effect, has avoided skew loosening.And through adopt embed fixing above-mentioned porosity porous tantalum product 13 plant tooth body 1, meet its structural mechanical property requirement in application, and also make bone grow into and the structure of growing in having formed, thereby organically combine as a whole with body bone tissue, in greatly having improved biocompatibility, also well meet its mechanical property, improved service life and implanted comfort level, increased stability and anti-verticity after artificial prosthesis is implanted.
