As shown in Fig. 3, Fig. 4 and Fig. 8 A～8D, the present embodiment exists with the difference of embodiment one
In: the bottom of the interior-change-exterior base station 2 of the present embodiment is for being shaped with externally threaded cylinder, and middle part is straight
Footpath more than the cylinder of lower cylindrical diameter, the top on top be frustum, bottom be cylinder, interior
Turn and have, on outer base station 2, the screwed hole B201 threadeded with angle screw 4.Correspondingly,
Having screwed hole A101 in the implantation body 1 of the present embodiment, this screwed hole A101 is shoulder hole,
Upper diameter is more than lower diameter, and the less bottom of diameter is shaped with female thread.Interior-change-exterior base station
The bottom of 2 is connected with the lower thread of screwed hole A101, the middle part of interior-change-exterior base station 2 and spiral shell
The top of pit A101 abuts, the top of interior-change-exterior base station 2 and metal base station 301 grafting.
Other are all identical with embodiment one.
Tooth-planting edentulous jaw of the present invention repairs the using method step of wide-angle pontic base station such as
Under:
A. implantation body 1 is implanted in the alveolar bone in the gingiva of oral cavity；
B. interior-change-exterior base station 2 is threadeded with implantation body 1；
C. metab is cast the metal base station 301 of base station 3 down with interior-change-exterior base station 2
Plug；
D. angle screw 4 is put into by the through hole 303 on metab casting base station 3, then
With angle screw cutter 5, this angle screw 4 is threadeded with interior-change-exterior base station 2, angle the drive
Screwdriver 5；
E. in oral cavity, plaster model after delivery, is routed up, by implantation body 1 during overmolded
Replacement body embedment plaster model in, back out angle screw 4 with angle screw cutter 5, take off gold
Belong to base casting base station 3, the replacement body of implantation body 1 is installed interior-change-exterior base station 2, then
Metab casts base station 3 be arranged on interior-change-exterior base station 2 by step C；
F. heating angle rod 6 is put into the through hole 303 on metab casting base station 3,
The plastics base station 302 of metab casting base station 3 is heated, makes plastics base station 302 curved
Qu Zhiyu former tooth direction keeps consistent angle, waits and extracts heating angle rod 6 after cooling out；
G. with angle screw cutter 5, angle screw 4 is backed out, take off and changed plastics base station
The metab casting base station 3 of 302 angles；
H. by taking off this metab casting base station 3 on plaster model, cast at metab
Investment (investment of the present embodiment can be silicate) in base station 3 outer wrapping, and in embedding
Reserving casting channel on material, one end of metal base station 301 is exposed at outside investment；
I. the metab having wrapped up investment is cast base station 3 and put in foundry furnace, use
Centrifugal casting (centre spinning method of the present invention is prior art), i.e. plastics base station 302 exists
Fusing in foundry furnace, forms space in investment, and (metal of the present embodiment can be metal water
Chromium, nickel, palladium, gold or silver) under the influence of centrifugal force by casting channel reserved on investment
Enter molding in this space；
J., after casting, take out metab casting base station 3, this metab is cast base station 3
Extracted out by investment, at the metal water moulding section tooth replacement on metal base station 301 top,
Again metab is cast base station 3 again with oral cavity gingiva in interior-change-exterior base station 2 in alveolar bone
Bonding.
In step D, the hemisphere 502 of angle screw cutter 5 is placed in interior hexagonal screwed hole 401
In, abutted with interior hexagonal screwed hole 401 by die nut 501, drive angle screw 4 turns
Dynamic；Ensure that angle screw cutter 5 and angle screw 4 have enough contacts area to rotate and producing
Raw frictional force, be delivered to angle screw 4 then with obtuse angle angle by angle screw 4 along obtuse angle
Metab casting base station 3 screw in interior-change-exterior base station 2.Utilize the axial of angle screw cutter 5
Angle between the longitudinal center line of centrage and angle screw 4 is obtuse angle, at dismounting angle spiral shell
During silk 4, solve the concordance of implantation body 1 and alveolar bone vertical direction to greatest extent, have
Effect solve edentulous jaw plantation, more than four plantation base station common path of insertion problems, for various greatly
After angle plantation, numerous and diverse various repair mode provides simplicity, fast, and safety is stable
Reparation means.
The wide-angle of the present invention is up to 64 °, and the most adjacent two interdental angles are to the maximum
64°；Wherein, implantation body 1 can be the most inclined 22 °, utilizes angle screw cutter 5 and angle spiral shell
Obtuse angle angle between silk 4, also can the most inclined 10 ° (the i.e. longitudinal center lines of angle screw cutter 5
And the angle between the longitudinal center line of implantation body 1), so, tooth is adjacent
Another interdental angle i.e. can reach and is (22 °+10 °) × 2=64 ° to the maximum.
When angle screw 4 is slipped into by through hole 303, angle screw cutter 5 is utilized to be tightened in interior-change-exterior
Time on base station 2, the draw-in groove in metab casting base station 3 is relied on to be fixed on interior-change-exterior base station 2
On, metab casting base station 3 is also acted as suppression simultaneously.On angle screw 4 top
The chamfer design of lower surface edge, can freely come in and go out and be adjusted to the metal portion casting of required angle
Make the internal screw passage in obtuse angle (i.e. changing the through hole 303 after angle) of base station 3.Interior-change-exterior
Base station 2 can be connected with each other with any implantation body of interior connection system.
The material of metal base station 301 can be cobalt chrome molybdenum, and cobalt chrome-molybdenum metal makes cobalt chromio platform；System
Make to may utilize during cobalt chromio platform the plastics base of heating angle rod 6 conversion metab casting base station 3
The angle of platform 302, is arbitrarily adjusted to required angle.Bottom gold because of metab casting base station 3
The design belonged to is non-anti-rotation, therefore cooperates can also take in mouth with heating angle rod 6
Use when the special transfer levers of pontic during dental cast.Eliminate clinic to need to be equipped with the tired of multiple accessory
Angry.
The material of heating corner rod 6 can be steel, heats heating corner rod 6, and utilization adds
Hot corner rod 6 by conduction of heat to plastics base station 302 so that it is obtain required angle after bending.
The present invention solves the wide-angle intractable case of edentulous jaw plantation, solves oral cavity industry anodontia
The more perfect aesthetic effect that jaw plantation is repaired.The purpose changing angle is, due to various
Reason causes implantation body 1 to implant the angle difference of alveolar bone, causes screwed hole B201 towards lip
Side or during excessively deviation is remote or near in, be not easy to the wide-angle problem repaired, and without altogether in addition
Aesthetic orthopaedics is cannot be carried out with problems such as paths of insertion.The invention provides brand-new thinking, indicate
New edentulous jaw plantation direction.
Along with China tends to the future of aging, edentulous jaw case will the most constantly be incremented by, compared with
High external product, domestic old man is by the edentulous jaw plantation product in the urgent need to being suitable for self.
The present invention repairs the price of product by reducing domestic Yu external edentulous jaw plantation, and promotes state
Interior edentulous jaw plantation recovery technique, the most kindness masses.
