Description
Technical field
This utility model relates to canine implant, relates in particular to a kind of sealing Dental Implant.
Background technology
Canine implant is widely used in Buccodental plants in operation, and it is to separate at present the most effective medical skill means of breach inner teeth gear disappearance.Its Dental Implant structure mostly includes implantation body, base station and artificial tooth.Implantation body imbeds after dental bed in advance, and its top refills and establishes base station, and this base station exposes to dental bed surface the corresponding artificial tooth of installing again, with this, realizes the implantation of artificial tooth.Yet also there is following shortcoming in existing canine implant: between Dnetal implant component, connect defective tightness firm, and sealing is poor, easily causing the materials such as kindred chip to fall into it connects 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 etc., and these technical problems have directly affected the clinical application effect of canine implant.
Utility model content
The purpose of this utility model is to provide a kind of sealing Dental Implant, and sealing Dental Implant, for sealing designs, facilitates and implants, and has good mechanical property and biocompatibility concurrently.
The purpose of this utility model is achieved in that
A sealing Dental Implant, it comprises implantation body, base station and artificial tooth, it is characterized in that: 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; Described implantation body adopts porous tantalum product, and its porosity is 60% ~ 70%; The outer surface of described implantation body middle and lower part is arranged with axial cutting edge; The outer surface at the implantation body middle part between this axial cutting edge is also provided with discontinuity screw thread; Between described implantation body and described base station, adopt gas thread to connect.
As further optimization, between above-mentioned implantation body and above-mentioned base station, adopt gas thread to connect and be specifically achieved in that above-mentioned implantation body inside is provided with groove, this groove 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 described groove 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 the threaded rod of its underpart, and while and artificial tooth corresponding matching, further to increase anti-axial-rotation.
The quantity of above-mentioned spring is preferably two, and arranges up and down.Above-mentioned slide block is provided with two grooves of arranging up and down corresponding to mounting spring place.
In this utility model, implantation body 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; By axial cutting edge and discontinuity screw thread are set, while not only making it pierce, resistance is less, pierces convenient again, the misery that patient suffers reduces greatly, also realized with alveolar bone and being firmly connected, further prevented from and rotation, strengthened with the firm of alveolar bone and be connected.

The specific embodiment
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 sealing Dental Implant, it comprises implantation body 1, base station 2 and artificial tooth 3; In its base station 2 heads, be provided with rectangular through-hole 4, in this rectangular through-hole 4, there are two springs 5 of arranging up and down, spring 5 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, and corresponding two grooves 12 that are provided with mounting spring 5 on slide block 6; The interior correspondence of its artificial tooth 3 is provided with the caulking groove 7 that slide block 6 is installed; Its implantation body 1 adopts porous tantalum product, and its porosity is 60% ~ 70%, and this porous tantalum product specifically can adopt method preparation described in patent 201110296515.7; And the outer surface of implantation body 1 middle and lower part is arranged with two axial cutting edges 10; The outer surface at implantation body 1 middle part that this axial cutting edge is 10 is also provided with discontinuity screw thread 11; Its implantation body 1 inside is provided with groove 8, and it is the gas thread of 55 ° that these groove 8 sides are provided with tooth form angle; Its base station 2 bottoms are threaded rod 9, the gas thread corresponding matching of this threaded rod 9 and groove 8 sides; 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 3 corresponding matching, have realized the implantation of artificial tooth.
Through adopting the implantation body 1 of the porous tantalum product of above-mentioned porosity, can meet its structural mechanical property requirement in application, can also make osseous tissue grow into and the structure of growing in forming, thereby organically combine as a whole with body bone tissue, when 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.
