It applies and is provided with threaded hole A101 on the planting body 1 of example, threaded hole A101 is stepped hole, and upper diameter is greater than lower diameter, and straight
The lesser lower part of diameter is formed with internal screw thread.The lower part of interior-change-exterior base station 2 is connect with the lower thread of threaded hole A101, interior-change-exterior base station
2 middle part is abutted with the top of threaded hole A101, the top of interior-change-exterior base station 2 and 301 grafting of metal base station.Other with implementation
Example one is identical.
Steps are as follows for the application method of tooth-planting edentulous jaw reparation wide-angle pontic base station of the present invention:
A. planting body 1 is implanted in the alveolar bone in the gum of oral cavity；
B. interior-change-exterior base station 2 is threadedly coupled with planting body 1；
C. the metal base station 301 of metab casting base station 3 is plugged with interior-change-exterior base station 2 downward；
D. angle screw 4 is put by the through-hole 303 on metab casting base station 3, then with angle screw knife 5 by the angle
Degree screw 4 is threadedly coupled with interior-change-exterior base station 2, angle the drive screwdriver 5；
E. plaster cast is routed up after modulus in oral cavity, the substitution body of planting body 1 is embedded to gypsum during overmolded
In model, angle screw 4 is backed out with angle screw knife 5, metab casting base station 3 is removed, pacifies on the substitution body of planting body 1
Interior-change-exterior base station 2 is filled, is then mounted on metab casting base station 3 on interior-change-exterior base station 2 by step C；
F. it will heat in the through-hole 303 that angle stick 6 is put on metab casting base station 3, base station 3 cast to metab
Plastics base station 302 heated, make the bending of plastics base station 302 to the angle that is consistent with former tooth direction, wait to be cooled
Extraction heating angle stick 6 afterwards；
G. angle screw 4 is backed out with angle screw knife 5, removes the metab for having changed 302 angle of plastics base station
Cast base station 3；
H. by removing metab casting base station 3 on plaster cast, embedding is superscribed outside metab casting base station 3
Expect (investment of the present embodiment can be silicate), and reserves casting channel on investment, one end dew of metal base station 301
Outside investment；
I. the metab for having wrapped up investment casting base station 3 is put into foundry furnace, it is (of the invention using centrifugal casting
Centre spinning method is the prior art), i.e., plastics base station 302 melts in foundry furnace, and space, metal water are formed in investment
(metal of the present embodiment can be chromium, nickel, palladium, gold or silver) under the influence of centrifugal force by investment reserve casting channel into
Enter in the space and forms；
J. it after casting, takes out metab and casts base station 3, by metab casting base station 3 by being extracted out in investment,
The metal water moulding section tooth replacement on 301 top of metal base station, then by metab casting base station 3 again and in the gum of oral cavity
Interior-change-exterior base station 2 in alveolar bone is bonded.
In step D, the hemisphere 502 of angle screw knife 5 is placed in interior hexagonal threaded hole 401, passes through die nut 501
It is abutted with interior hexagonal threaded hole 401, angle screw 4 is driven to rotate；It is enough to ensure that angle screw knife 5 and angle screw 4 have
Contact area to rotate generation frictional force, be transmitted to angle screw 4 then with obtuse angle angle by angle screw 4 along obtuse angle
Metab casts base station 3 and screws in interior-change-exterior base station 2.Utilize the longitudinal center line of angle screw knife 5 and the axial direction of angle screw 4
Angle between center line is obtuse angle, and when dismantling angle screw 4, it is vertical with alveolar bone to solve planting body 1 to the maximum extent
The consistency in direction efficiently solves the problems, such as edentulous jaw plantation, four or more plantation base station common path of insertion, is various wide-angles
After plantation, the repair mode of many and diverse multiplicity provides simplicity, fast, safety, stable reparation means.
For wide-angle of the invention up to 64 °, i.e., adjacent two interdental angles are up to 64 °；Wherein, planting body 1
Can outward inclined 22 °, it, can also inclined 10 ° of (i.e. angle screw knives 5 again using obtuse angle angle between angle screw knife 5 and angle screw 4
Longitudinal center line and planting body 1 longitudinal center line between angle), in this way, another tooth that a tooth is adjacent thereto
Angle between tooth, which can reach, is up to (22 °+10 °) × 2=64 °.
When angle screw 4 is slid by through-hole 303, when being tightened on interior-change-exterior base station 2 using angle screw knife 5, by gold
The card slot belonged in pedestal casting base station 3 is fixed on interior-change-exterior base station 2, while also acting as compacting to metab casting base station 3
Effect.The chamfer design at 4 top upper and lower surface edge of angle screw, can freely enter and leave the metal portion for being adjusted to required angle
Cast screw passage inside the obtuse angle of base station 3 (through-hole 303 i.e. after change angle).Interior-change-exterior base station 2 can be with interior connection system
Any planting body be connected with each other.
The material of metal base station 301 can be cobalt chrome molybdenum, and cobalt chrome-molybdenum metal makes cobalt chromium base station；Make cobalt chromium base station Shi Keli
The angle that metab casts the plastics base station 302 of base station 3 is converted with heating angle stick 6, is arbitrarily adjusted to required angle.Because of metal
The design that pedestal casts the bottom metal of base station 3 is non-anti-rotation, therefore can also be in mouth with the heating mutual cooperation of angle stick 6
It takes when dental cast when the dedicated transfer levers of pontic use.Eliminate the clinical worry for needing to be equipped with a variety of accessories.
The material for heating corner stick 6 can be steel, heat to heating corner stick 6, using heating corner stick 6 by heat transfer
To plastics base station 302, required angle is obtained after being bent it.
The present invention solves the wide-angle intractable case of edentulous jaw plantation, solves the plantation of oral cavity industry edentulous jaw and repairs more
Add perfect aesthetic effect.The purpose for changing angle is, planting body 1 is caused to be implanted into the angle of alveolar bone not due to various reasons
Together, in causing threaded hole B201 towards lip side or excessively deviateing in remote or is close, it is not easy to the wide-angle problem repaired in addition, and
The problems such as no common path of insertion, can not carry out aesthetic orthopaedics.The present invention provides completely new thinkings, specify new edentulous jaw kind
Plant direction.
As China tends to the future of aging, edentulous jaw case will constantly be incremented by every year, compared with high external product,
Domestic old man is by there is an urgent need to be suitble to the edentulous jaw of itself to plant product.The present invention will reduce the domestic edentulous jaw with foreign countries and plant
The price of product is repaired, and promotes domestic edentulous jaw plantation recovery technique, at last kindness masses.
