Description
Technical field
This utility model relates to canine implant, relates in particular to a kind of tubular type 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 the extensive use of this technology, it exists many technical disadvantages also gradually to appear and becomes technical barrier and needs to be improved and break through.
At present, in Dental Implant structure, be all in dental bed, to imbed in advance one to plant tooth body mostly, after refill above it and establish base station, this base station exposes to dental bed surface the corresponding artificial tooth of installing again, with this, realizes the implantation of artificial tooth.Yet it is firm between its Dnetal implant component, to connect defective tightness, and sealing is poor, easily cause the materials such as kindred chip to fall into it and connect between gap, after long-time use, not only easily cause wearing and tearing, and the loose or dislocation that also can further cause syndeton, service life is not long; And it is mostly closed structure design, once be difficult to add in its structure again other to promote the benefit materials such as thing after implanting.In addition, it is also vulnerable to alternating force effect and occurs loose or dislocation, if loosening skew especially when mounted, can not recoil to former allocation, can not again tighten thereby cause again significant wastage etc., these technical problems have directly affected its clinical application effect, and become the technical bottleneck for the treatment of in breaking through.
Utility model content
The purpose of this utility model is to provide a kind of tubular type Dental Implant, and between this tubular type Dnetal implant component, for sealing connects, the effect that can resist alternating force, conveniently implants, and has good mechanical property and biocompatibility concurrently.
The purpose of this utility model is achieved in that
A tubular type 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; In described artificial tooth, correspondence is provided with the caulking groove that slide block is installed; The described tooth body of planting adopts porous tantalum product, and its porosity is 60% ~ 70%; Described outer surface of planting tooth body middle and lower part is arranged with axial cutting edge; The tooth body middle part outer surface of planting 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; 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; It is planted between tooth body and base station and adopts gas thread to connect.
As further optimization, above-mentioned planting between tooth body and above-mentioned base station adopts gas thread connection to be specifically achieved in that above-mentioned perforated side is provided with gas thread; Above-mentioned base station bottom is threaded rod, and the gas thread corresponding matching of this threaded rod and perforated side is fixedly connected with the sealing that realizes the two.
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 a plurality of.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 mobility that materials are waited at the broken end of flesh and blood simultaneously, make it and be set to porous tantalum product to plant tooth body better compatible.
In this utility model, plant tooth body inside and have the perforation running through up and down, and the guiding gutter being communicated with this perforation, realized sclerotin weakness such as planting tooth body bottom has been introduced, has been evenly distributed on to the materials 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; It is planted tooth body and is connected by gas thread with base station, easily produces self-locking, good stress performance, and for sealing connects, avoided impurity to introduce in its joint gap, reduce wearing and tearing, extended service life.In addition, by Compress Spring is set, also resist well the effect of alternating force, as be subject to alternating force effect, can recoil to former allocation, avoided skew loosening.
