Abstract
The invention discloses a kind of keyway type precision connectors, it is padded including connector, body and key way, one end of connector is fixedly connected with a side of retainer, the body is arranged in the other end of connector, the key way with the body mechanical interlock is offered on pontic, and key way liner is embedded on the key way.It can efficiently solve that clinically abutment edge seal is bad, the problem of doctor's difficulty with tooth.Compact structure is reasonable, is easily installed, and can efficiently solve no common path of insertion problem, solves in place and hat set is edge sealing, protect abutment.
Description
Technical field
The present invention relates to artificial tooth processing technique fields, more particularly, to a kind of keyway type precision connector.
Background technique
For present artificial tooth processing factory when the bridge that fixes is repaired, abutment is and clinical there are common path of insertion deviation is bigger
Doctor consider Abutment for Vital Teeth perforation of pulp chamber can not again for tooth when, often by abutment fill gypsum come make up path of insertion deficiency
Problem leads to the interior sky of concave region hat set in patient mouthful, and the risk that edge is not effectively sealing off, hat set loosens over time,
Abutment is impaired.
Summary of the invention
The present invention is directed to the problem of abutment path of insertion deficiency, provides a kind of keyway type precision connector, can effectively solve
Certainly clinically abutment edge seal is bad, the problem of doctor's difficulty with tooth.
The present invention is to be addressed above-mentioned technical problem by the following technical programs.
Keyway type precision connector, including connector, body and key way liner, one end of connector and the side of retainer
End is fixedly connected, and the body is arranged in the other end of connector, and the key way with the body mechanical interlock, institute are offered on pontic
It states and is embedded with key way liner on key way.
Preferably, the connector, the body and the retainer are an integral molding structure.
Preferably, the connector, the body and the retainer are casting and forming structure.
Preferably, the connector, the body and the retainer are Milling Process forming.
Preferably, the connector is rectangular cross section.
Preferably, the area of the connector cross section is not less than 6mm2。
Preferably, the key way liner is nylon material.
Preferably, the body is cylinder, the key way liner is semi-cylindrical shaped.
Preferably, the key way is opened up from a side lower part of pontic, it is described after the retainer is set on abutment
Pontic is installed downwards by upper vertical is fixed into the body with the common mechanical interlock of the key way by key way liner
One.
To sum up, keyway type precision connector of the invention, compact structure is reasonable, is easily installed, and can efficiently solve
Without common path of insertion problem, solves in place and hat set is edge sealing, protect abutment.
1. not affecting the appearance, good function can be exercised, belongs to precision connector in hat.
2. durable makes abutment and missing position mucous membrane bear bite force jointly.
3. doctor need not make up undercut problem with binder, keeps hat and abutment height closely connected, protect abutment.
Detailed description of the invention
It is intended to not constitute a limitation on the scope of protection of the present invention convenient for description preferred embodiment in conjunction with the following drawings.
Fig. 1 is the structural formula schematic diagram under the non-installation condition of the embodiment of the present invention；
Fig. 2 is the structural formula schematic diagram of the embodiment of the present invention in the mounted state.
In figure: 1- connector, 2- body, 3- key way liner, 4- retainer, 5- pontic, 6- abutment.
Specific embodiment
In order to facilitate the present invention is understood, with reference to the accompanying drawing in the preferred embodiment of the invention that provides to the present invention into
The detailed description of row.
As depicted in figs. 1 and 2, the keyway type precision connector of the embodiment of the present invention, including connector 1, body 2 and key way
Liner 3, one end of connector 1 is fixedly connected with a side of retainer 4, and the body 2 is arranged in the other end of connector 1.It is simultaneous
Care for and consider manufacture craft and structural strength, the connector 1, the body 2 and the retainer 4 preferably using one at
Type structure.When using metal material, casting and forming structure is can be used in the connector 1, the body 2 and the retainer 4.
When using being such as the full porcelain material of zirconium dioxide, the connector 1, the body 2 and the retainer 4 can be used Milling Process at
Shape.
In the present embodiment, the connector 1 uses rectangular cross section structure, also, in order to guarantee structural strength, described
The area of cross section is preferably not less than 6mm2。
The key way with 2 mechanical interlock of body is offered on pontic 5, and key way liner 3 is embedded on the key way.It is described
Body 2 plays a part of to change common path of insertion, has common path of insertion with other end abutment/bridge when placement.The key way liner 3 is excellent
It is selected as nylon material, it is wear-resistant, it is that mechanical caulked is fixed together with the key way on the pontic 5.As shown in Figure 2,
For semifixed bridge structure, the retainer one end at pontic both ends is motionless connection, and one end is keyway type connection, and such keyway type connects
The design of binding structure can well connect both ends retainer, and it is closely sealed and can guarantee abutment marginal fit to form one section of height
Fixed bridge.
In a specific embodiment, the body 2 is cylinder, and the key way liner 3 is semi-cylindrical shaped.Further
, the key way is opened up from a side lower part of pontic 5, after the retainer 4 is set on abutment 6, the pontic 5 is by top
Installation vertically downward makes the body 2 be integrally fixed by key way liner 3 with the common mechanical interlock of the key way.
Several technical terms used in the present invention are intended merely to facilitate description, are not construed as limiting the invention,
The present invention is not limited to above-described preferable embodiment, the public affairs that can be known based on those skilled in the art
Know technology or use and is capable of the various modifications of equivalence replacement and the embodiment of change in the prior art, it is all to be based on this hair
Bright spirit or technical concept, should all be included in the protection scope of the present invention.
