Specific embodiment
It is below with reference to the accompanying drawings and in conjunction with the embodiments, next that the present invention will be described in detail.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of elasticity dentistry implant base station of expanded containing snap ring, 1 center edge of base station
Its axial direction is provided with the mounting hole 10 for installing center screw 3,1 top of base station radially open up there are six with mounting hole 10
The positioning through hole 6 being connected is equipped with the snap ring 2 in torus in mounting hole 10, and the positioning column 16 that 2 periphery of snap ring is arranged in blocks
Snap ring 2 is fixed in mounting hole 10 in corresponding positioning through hole 6, and the inner wall of the outer peripheral surface of snap ring 2 and mounting hole 10
It is fitted close, the bottom end of snap ring 2 and the top of center screw 3 are fitted close.
Snap ring 2 is installed in the mounting hole 10 at 1 center of base station, and is stuck in and is set in 2 periphery of snap ring setting positioning column 16
Snap ring 2 is fixed in mounting hole 10 in the positioning through hole 6 on 1 top of base station, makes the outer peripheral surface of snap ring 2 and the inner wall of mounting hole 10
It is fitted close, the top tight fit of the bottom end of snap ring 2 and center screw 3, so that realizing prevents binder in planting body 4 and base
The leakage of 1 contact portion of platform, guarantees the biological sealing of gingiva tissue, avoids result in bacteria planting and causes peri-implantitiss；Together
When binder can be bonded in 6 end of positioning through hole positioned at the outside of base station 1, improve binder in the connection energy on 1 surface of base station
Power improves the fastness that corona and base station 1 bond.
1 top of base station is equipped with multiple tracks radially and the groove of the notch 5 of penetrating mounting holes side wall.The groove of the notch 5 further increases
The bond area of binder and 1 surface of base station, so that base station 1 and corona assembly are more stable.
The bottom of the groove of the notch 5 is connected with positioning through hole 6, during installation, by the positioning column 16 of 2 periphery of snap ring along notch
Slot 5 moves from up to down, then fills in positioning through hole 6, and the setting of the groove of the notch 5 also facilitates the installation of positioning column 16；Notch
The width of slot 5 is less than the diameter of positioning through hole 6, is capable of fixing positioning column 16 in positioning through hole 6, prevents positioning column 16 from moving up
Into the groove of the notch 5.
1 top of base station is the thin rotary body 11 in intermediate thick both ends, is cylindrical body 12 in the middle part of base station 1, and 1 lower part of base station is rounding
Stage body 13,1 bottom of base station are hexagonal prisms 14.1 top of base station is arranged to the intermediate thick thin rotary body 11 in both ends, among rotary body 11
Thick part improves the stability of fixation to corona, engaging.
The taper of the rounding stage body 13 of 1 lower part of base station meets Morse's taper, with the taper at the top of planting body 4 being in Morse's taper
Hole cooperation, make between 1 lower part of base station and 4 top contact of planting body generate frictional force improve planting body 4 contacted with base station 1 it is steady
Solidity.
In mastication processes, bite force is transmitted gradually downward by corona, base station 1, center screw 3, planting body 4, because of kind
Lack the buffer function of parodontium around implant 4, it is interior that region of stress concentration is that 4 neck of planting body, planting body 4 are contacted with base station 1
Portion is easy to cause 4 surrounding bone resorption of planting body, and it is steady in a long-term to be unfavorable for planting body 4.The middle part of base station 1 cylindrical body 12 it is outer
Side is equipped with micro- screw thread 15, increases the contact area of surrounding tissue Yu base station 1, is conducive to planting body --- and base station system is consolidated
Position, guarantees the long-time stability of implant system.
In order to further increase the stability of planting body 4, it is equal with the outer diameter of outer portion to remove rotary body 11 for base station 1 in the present invention
Less than 4 outer diameter of planting body, Finite element analysis results show that region of stress concentration inwardly shifts, and alleviate answering for 4 neck of planting body
Power is concentrated, and stress is effectively dispersed to cancellous bone, the absorption of 4 neck bone tissue of planting body is efficiently reduced, is conducive to cover
It is placed on the stabilization of edge bone surface soft tissue.
10 upper section of mounting hole is cylindrical hole 7, and 10 middle section of mounting hole is bus and axis angle falling between 60~70 °
Rotary table type hole 8, inverted round stage type hole 8 herein are to match with the head bottom surface of center screw 3, and 10 lower section of mounting hole is circle
Column type hole 9.
The manufacture material of snap ring 2 is polyether-ether-ketone, with preferable biocompatibility and mechanical performance, elasticity modulus compared with
Close to true bone, stress buffer can be played the role of.
In addition, bioactivity glass can also be used for snap ring 2 or multi-walled carbon nanotube is made.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
