When raw loosening, relatively rotate with body portion 2.And the antitorque effect in the antitorque portion 7 of " ten " font is more antitorque than one-shaped
The antitorque effect in portion 7 is good.
Embodiment 2
Embodiment 2 difference from example 1 is that base station 4 difference.
Fig. 2 is reviewed, base station 4 is set as split type structure, the gum connection of artificial tooth interconnecting piece 41 and lower part including top
Portion 42, artificial tooth interconnecting piece 41 and denticle 3, which are integrally formed, to be arranged, and gum interconnecting piece 42 and body portion 2 are integrally formed and are arranged, artificial tooth connection
Portion 41 is inserted into gum interconnecting piece 42, and artificial tooth interconnecting piece 41 and gum interconnecting piece 42 are detachably fixed connection.Denticle 3, base station 4
Middle part aperture, connecting hole 21 is offered in body portion 2, and connecting hole 21 is blind hole and is equipped with helicitic texture, gum interconnecting piece 42 and body
Portion 2 is embedded in gum, and central bolt 5 is each passed through after denticle 3, artificial tooth interconnecting piece 41 and gum interconnecting piece 42 and body portion 2
It is threadedly coupled, so that base station 4, denticle 3 and body portion 2 is fixed.
By the way that base station 4 is made into split type structure, while the top of base station 4 and denticle 3 are made of one structure, by base station
4 lower part and body portion 2 are made of one formula structure, and this method not only solves the problem of base station 4 is easy to fall off with denticle 3, and
And the split type interdental installation different in two length preferably of base station 4, so that the installation of planting body is more square
Just.
Due to this artificial tooth during use stress when, be easy to happen relative rotation between two parts base station 4, thus
So that artificial tooth loosens, therefore the location structure for preventing the two from loosening is equipped between artificial tooth interconnecting piece 41 and gum interconnecting piece 42.
In conjunction with Fig. 5, artificial tooth interconnecting piece 41 include with the integrally formed circular artificial tooth connection sheet 411 in 3 lower surface of denticle, with
And the integrally formed columned artificial tooth connecting column 412 in 411 lower surface of artificial tooth connection sheet.The close artificial tooth of artificial tooth connecting column 412
The outer peripheral surface of the end of connection sheet 411 is uniformly provided with three positioning columns 43 around its axis, and three positioning columns 43 are in artificial tooth connecting column
412 outer peripheral surfaces form a triangle, and this arrangement mode of positioning column 43 makes artificial tooth interconnecting piece 41 and gum interconnecting piece 42
Stability is more preferable when connection；The cross section of positioning column 43 be in semicircle shape, lateral surface be arc surface, and one end of positioning column 43 with
Artificial tooth connection sheet 411 is fixedly connected, since cantilever beam effect can be generated on artificial tooth connecting column 412 when 32 points of stress of denticle,
Positioning column 43 is fixedly connected with the knot that can increase between 41 end of artificial tooth interconnecting piece and artificial tooth interconnecting piece 41 with artificial tooth connection sheet 411
The stability of structure and the bending resistance of artificial tooth connecting column 412.
The outer peripheral surface of the end of the separate artificial tooth connection sheet 411 of artificial tooth connecting column 412 is uniformly provided with three around its axis and leads
To item 44,44 cross section of gib block is in rectangle, and gib block 44 is located in a straight line with positioning column 43.
In conjunction with Fig. 6, gum interconnecting piece 42 is cylindrical and has a diameter larger than the diameter of artificial tooth interconnecting piece 41, and gum connects
The insertion of the hollow permission artificial tooth interconnecting piece 41 in portion 42.The inner peripheral surface of gum interconnecting piece 42 is equipped with interconnected locating slot 22 and guiding
Slot 23, locating slot 22 allow positioning column 43 to be inserted into, and are set to the one end in the separate body portion 2 of gum interconnecting piece 42；Guide groove 23 is permitted
Perhaps gib block 44 is inserted into, and is set to the one end in the close body portion 2 of gum interconnecting piece 42.
When installing artificial tooth, when artificial tooth interconnecting piece 41 is plugged in gum interconnecting piece 42, gib block 44 is plugged in first is led
Into slot 23, then positioning column 43 is plugged in inside positioning column 43, central bolt 5 is finally each passed through denticle 3, artificial tooth connects
It is fixed with body portion 2 behind portion 41 and gum interconnecting piece 42.
Gib block 44 plays the role of that guidance can be played during installation, does not need specially to adjust positioning column 43 and locating slot
22 position, when gib block 44 is plugged in guide groove 23, positioning column 43 is opposite with the position of locating slot 22 to be determined.Positioning column 43
With the cooperation of locating slot 22, when can prevent 3 stress of denticle, artificial tooth interconnecting piece 41 and gum interconnecting piece 42 generate relative rotation, make
Denticle 3 is obtained to fall off.
Review Fig. 2, a kind of connection type as central bolt 5 and artificial tooth connecting column 412: artificial tooth connecting column 412 it is interior
Portion is hollow and is equipped with internal screw thread；The end that central bolt 5 is connected with artificial tooth connecting column 412 opens up helicitic texture, and central bolt 5 is worn
After crossing artificial tooth connecting column 412, the both ends of central bolt 5 are fixed with body portion 2 and artificial tooth connecting column 412 respectively, so that base station 4 be consolidated
It is fixed.
In conjunction with Fig. 7, a kind of preferred connection type as central bolt 5 and artificial tooth interconnecting piece 41: central bolt 5 is set as
Step-like, the end of central bolt 5 connecting with artificial tooth connecting column 412 is bigger diameter end 51, and central bolt 5 is connect with body portion 3
End be miner diameter end 52, miner diameter end 52 be equipped with helicitic texture compatible with the connecting hole 21 in body portion 2, bigger diameter end 51 it is straight
Diameter is greater than the diameter of miner diameter end 52；The inner wall of the close artificial tooth connection sheet 411 of artificial tooth connecting column 412 is equipped with cricoid blocking portion
6.After central bolt 5 is passed through artificial tooth connecting column 412 and body portion 3, miner diameter end 52 is threadedly coupled with body portion 2, bigger diameter end 51
End face close to body portion 3 is abutted with blocking portion 6, so that artificial tooth connecting column 412 and gum interconnecting piece 42 and body portion 3 is fixed.
By this fixed form, central bolt 5 and artificial tooth connecting column 412 are clamped, and are threadedly coupled with body portion 2, more
It is convenient, fast, the plantation efficiency of tooth-implanting can be improved.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
