Abstract
The invention relates to a plug-type retention structure of an implant abutment, and belongs to the technical field of stomatology. The plug-type retention structure of the implant abutment is characterized in that internal threads are drilled in the bottom of the abutment, and internal threads at the lower segment (6) of the bottom of the abutment are inclined inwardly to form expansion threads (4) with a taper alpha; and internal threads at the upper segment (3) of the bottom of the abutment have no inclined angle, and the outer circumference of the bottom of the abutment is a smooth surface with a taper beta which is inclined inwardly. The taper alpha of the expansion threads (4) is larger than the taper beta of the outer circumference of the bottom of the abutment; and the lower segment (6) of the bottom of the abutment is evenly divided into a plurality of same expansion blocks (5) expanding outwardly along the axial circumference, and a 0.1 to 0.3mm clearance is reserved between every two expansion blocks (5). According to the plug-type retention structure of the implant abutment, the fatigue loosening of bolts can be prevented, the fatigue breaking of the bolts is eliminated, the axial rotational orientation can be automatically adjusted, the life of the denture is prolonged, and the comfort of the denture is improved.
Description
Technical field
Abutment plug-in type retention system, belongs to technical field of oral medicine, is specifically related to a kind of plug-in type base station.
Background technology
Since the sixties in last century, professor Branemark proposed synosteosis theory, implant denture is widely used in clinical medicine.Wherein, implantation body and base station are the indispensable parts of implant denture, in prior art, base station is all directly be fastened on implantation body upper end by bolt, belongs to and is rigidly connected, and to chew, speak etc. in process people, artificial tooth and tooth constantly collide, long term frequent collision makes fastening bolt that tired loosening easily occur, and serious may fracture, and affects the comfort level in life-span of artificial tooth and use procedure.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of Abutment plug-in type retention system preventing bolt fatigue break, improve artificial tooth service life.
The technical solution adopted for the present invention to solve the technical problems is: this Abutment plug-in type retention system, comprise the base station being fixed on implantation body upper end, described base station is divided into base station end, bottom base station cervical region and base station three sections, hypomere two parts bottom epimere and base station are divided into again bottom base station bottom base station, descend segment length all between 2 ~ 5mm bottom epimere and base station bottom base station, it is characterized in that: in bottom described base station, be drilled with female thread, bottom base station, hypomere female thread tilts to the inside, forming tapering is the expansion screw of α, bottom base station, epimere female thread is without angle of inclination, bottom base station, excircle is be the smooth surface of β with the tapering tilted to the inside, expansion screw tapering α > base station bottom external circumference tapering β, bottom base station hypomere vertically even circumferential be divided into multiple identical expanding block that can outwards expand, often all leave 0.1 ~ 0.3mm gap between adjacent two expanding blocks.Implantation body upper end is plugged on bottom base station, maintenance bolt stretches into bottom base station from base station end, enter epimere female thread bottom base station through the guiding of base station end female thread to be then meshed with expansion screw, because expansion screw has tapering α, expanding block can be driven in the process of tighting a bolt outwards to expand and to make base station bottom external circumference tapering β gradually trend towards 0, make tightly to fit with implantation body bottom base station.In grafting process, bolt is not connected with implantation body, and when needing to remove base station, base station takes out from implantation body by the available bolt that exits.
Described expansion screw tapering α=0 ~ 6 °.
Described base station bottom external circumference tapering β=0 ~ 6 °.
The quantity of described expanding block is 8 ~ 12.
Compared with prior art, the beneficial effect that the present invention has is: stop bolt fatigue break, automatically regulate gyrobearing vertically, improve artificial tooth life-span and comfort level: bottom base station, be plugged on implantation body upper end, and by designing suitable α and β angle, make in grafting process, bolt plays the effect making base station bottom expansion, do not produce with implantation body and be rigidly connected, bolt is not affected by external force, tired loosening can not be produced, stop bolt fatigue break, automatically regulate gyrobearing vertically, improve artificial tooth life-span and comfort level.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
Fig. 3 is that the A-A of Fig. 1 is to sectional view.
Wherein: 1, hypomere bottom epimere 4, expansion screw 5, expanding block 6, base station bottom base station end 2, base station cervical region 3, base station.
Detailed description of the invention
Fig. 1 ~ 3 are most preferred embodiments of the present invention, and below in conjunction with accompanying drawing 1 ~ 3, the present invention will be further described.
This Abutment plug-in type retention system can be divided into the Multiple Types such as I type, C type, M type, U type according to parameter difference.
Embodiment 1
With reference to accompanying drawing 1 ~ 3: this Abutment plug-in type retention system is I type, comprise the base station that can be fixed on implantation body upper end, base station is divided into base station end 1, bottom base station cervical region 2 and base station three sections, hypomere 6 two parts bottom epimere 3 and base station are divided into again bottom base station bottom base station, the long 4mm of epimere 3 bottom base station, the long 3mm of hypomere 6 bottom base station.Female thread is drilled with in bottom base station, bottom base station, hypomere 6 female thread tilts to the inside, form expansion screw 4, expansion screw 4 tapering α=2 °, bottom base station, epimere 3 female thread is without angle of inclination, and bottom base station, excircle is the smooth surface with tilting to the inside, base station bottom external circumference tapering β=1 °, bottom base station hypomere 6 vertically even circumferential be divided into 8 identical expanding blocks 5 that can outwards expand, all leave 0.1mm gap between every two expanding blocks 5.
Embodiment 2
This Abutment plug-in type retention system is C type, tapering α=3 ° of expansion screw 4, base station bottom external circumference tapering β=2 °, and expanding block 5 quantity is 10, and all the other settings are identical with embodiment 1.
Embodiment 3
This Abutment plug-in type retention system is M type, the long 3mm of epimere 3 bottom base station, tapering α=3 ° of expansion screw 4, base station bottom external circumference tapering β=2 °, and expanding block 5 quantity is 12, and all the other settings are identical with embodiment 1.
