Referring to figs. 1 to 5, in implementing the one of the utility model, provide a kind of air pressure intumescent integral type at
Matrix comprising: a balloon portion 10 and a matrix band portion 20.
The balloon portion 10 is hollow, internal gassy, in the present embodiment, according to actual requirement, the balloon portion
10 can accommodate the air of 3ml.The bottom of the balloon portion 10 has pleated structure 12, when 10 gassy of balloon portion,
The pleated structure 12 is to stretch shape, when the balloon portion 10 is by external forces (as squeezed), the pleated structure 12
It is contraction-like.When 10 gassy of balloon portion, the section of the balloon portion 10 is in approximate isosceles triangle.
The balloon portion 10 is connected with the matrix band portion 20.It is described after the balloon portion 10 is by external force
Gas (such as air) in balloon portion 10 can be transferred into the matrix band portion 20.
Gas is back to balloon portion 10 from matrix band portion 20 in order to prevent, therefore, is arranged one inside the balloon portion 10
Plastic buckle (is not marked in figure), and the plastic buckle includes that an insertion section 13 and one has the clamping part 14 being open.It is described to insert
Enter the top in portion 13 in cone-shaped.The top of the insertion section 13 is directed at the opening, when the balloon portion 10 is by external force
And when shrinking, the insertion section 13 is inserted into the opening (being not marked in figure), and the insertion section 13 be connected in it is described
Clamping part 14, so that the balloon portion 10 keeps the shape after being pressurized, so that by 10 nothing of balloon portion of extraneous squeezing action power
Method is restored to original volume, and which prevent the balloon portions 10, and rebound phenomenon occurs.
In the present embodiment, the balloon portion 10 is connected to the matrix band portion 20 by the hollow tube 11 of an elongate.
In addition, the hollow tube 11 of the elongate is made of the plastics with deformability.Then, doctor over the course for the treatment of, can
To be bent at any angle according to the requirement actually bent to the hollow tube 11, so that the matrix band portion 20 is accurately
Between the teeth space of patient (i.e. between a tooth 30 and another tooth 30) at position, it is also convenient for going on smoothly for operation.
The matrix band portion 20 be it is hollow, certain gas can be accommodated, and the matrix band portion 20 is arranged in patient
Teeth space position at (or the dental area of defect).When being not affected by from the gas that the balloon portion 10 is transmitted, the molding
The gas that piece portion 20 accommodates is the air of 1ml.When the gas transmitted by the balloon portion 10, the matrix band portion 20 is in
Swelling state, and the outer surface in the matrix band portion 20 can be tightly attached to facing 31.In this way, working as the abutting in the matrix band portion 20
When on tooth facing 31, doctor can (area filling has dental filling material according to the region that the matrix band portion 20 is limited
Material), the tooth 30 of defect is repaired, original structure is made it restore to.
Since the bottom in the matrix band portion 20 is designed as with pleated structure 21, when the matrix band portion 20 by
To after the air that balloon portion 10 is transmitted, become swelling state from contraction state, when the gas tool in the matrix band portion 20
When having certain volume, can preferably it be attached on facing 31.
In addition, in the present embodiment, the matrix band portion 20 is made of transparent plastic, in this way, facilitating doctor from teeth space side
The resin material in teeth space is irradiated in face, to improve working efficiency.
In the present embodiment, the air pressure intumescent integral molding piece further includes an air pressure ball 22, the air pressure ball 22
It is connected with the matrix band portion 20.The air pressure ball 22 is used to be greater than a preset pressure when the internal pressure in the matrix band portion 20
When (such as 3 standard atmospheric pressures), the air pressure ball 22 is expanded, to reduce the internal pressure in the matrix band portion 20, from
And patient is made to have preferable treatment body-sensing (there will not be biggish work to tooth because the internal pressure of the forming part is excessive
Firmly).
Detailed Jie has been carried out to a kind of air pressure intumescent integral molding piece provided by the utility model embodiment above
It continues.It should be understood that illustrative embodiments as described herein should be to be considered only as descriptive, it is used to help understand the utility model
Method and its core concept, and be not intended to limit the utility model.To feature or side in each illustrative embodiments
The description in face should usually be considered the similar features or aspects suitable for other exemplary embodiments.Although reference example is real
It applies example and describes the utility model, but can suggest that those skilled in the art carries out various change and change.The utility model
It is intended to cover these variations and change in the scope of the appended claims.
