Abstract
The utility model provides a kind of department of stomatology matrix band, including crescent diaphragm and extension plate, the extension plate is set in the middle part of crescent diaphragm inside edge, is located in same level with the crescent diaphragm, the extension plate is identical as the central axis of crescent diaphragm, and the two sides of the crescent diaphragm are symmetrically arranged with the aperture fixed convenient for beak before forming clip；The department of stomatology matrix band, structure is simple, designs for backteeth Proximal caries are bad to the resin fill reparation under gum, can preferably form interim hole wall, restore tooth contour.
Description
Technical field
The utility model relates to department of stomatology therapeutic device field, especially a kind of department of stomatology matrix band.
Background technique
Proximal surface is badly involved for backteeth dental caries at present and as deep as the resin fill reparation under gum, clinically generallys use forming
Piece system, in favor of tamping filler, restores tooth contour, and prevent and overhang to form interim hole wall.However it is existing
Some matrix bands are bad for dental caries as deep as the resin fill reparation under gum, and cavities lack interim hole wall under gum, cannot smoothly restore
Tooth contour.It often results in tooth contour and restores bad, the phenomenon that being formed of overhanging, doctor needs to modify resin shape or system again
Make self-control matrix band, not only brought extra workload to doctor, but also increases the consultation time and pain of patient.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of department of stomatology matrix bands.
In order to solve the above technical problems, the technical solution of the utility model is:
A kind of department of stomatology matrix band, including crescent diaphragm and extension plate, the extension plate are set to the crescent moon
It is located in same level in the middle part of shape diaphragm inside edge, with the crescent diaphragm, the extension plate and crescent film
The central axis of piece is identical, and the two sides of the crescent diaphragm are symmetrically arranged with several apertures fixed convenient for beak before forming clip.
Preferably, above-mentioned department of stomatology matrix band, the extension plate are duck-bill type structure, the extension plate central axial direction
Height and crescent diaphragm central axial direction height ratio be 1.5-2:1.
Preferably, above-mentioned department of stomatology matrix band, the aperture are diamond shape aperture, and each aperture edge is used equipped with quoit
It prevents from tearing to reinforce.
Preferably, the center of above-mentioned department of stomatology matrix band, ipsilateral each diamond shape aperture is located in a straight line.
Preferably, above-mentioned department of stomatology matrix band, the dimensions of the crescent diaphragm are as follows: wide × high × thick=
(25-40)mm×(5-10)mm×(0.038-0.05)mm。
Preferably, above-mentioned department of stomatology matrix band, material are hard transparent resin.
The utility model has the advantages that
Above-mentioned department of stomatology matrix band, structure is simple, sets for backteeth Proximal caries are bad to the resin fill reparation under gum
Meter can preferably form interim hole wall, restore tooth contour；The aperture of diaphragm two sides is the aperture of specific diamond structure,
The center of ipsilateral each diamond shape aperture is located in a straight line, and such arrangement mode can make beak before forming clip be stuck in diamond shape
It is difficult to slide on the angle of aperture, loosen, it is more firm, fixed convenient for beak before forming clip, so that clamping stronger is not easy to loosen；Often
A aperture edge is equipped with quoit, set to prevent the resin around diamond shape aperture from tearing because the material of diaphragm is resin
The quoit set plays the role of effectively reinforcing, prevents tearing.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of department of stomatology matrix band provided by the utility model,
In figure: the height of the width 4- crescent diaphragm of 1- crescent diaphragm 2- extension plate 3- crescent diaphragm
Spend the height 6- aperture 7- quoit of 5- extension plate central axial direction
Specific embodiment
Embodiment 1
As shown in Figure 1, the department of stomatology matrix band, material is hard transparent resin, including crescent diaphragm 1 and is prolonged
Long slab 2, the dimensions of the crescent diaphragm are as follows: width 3 × 4 × thickness of height (figure omits)=30mm × 7mm ×
0.04mm, the extension plate is set in the middle part of crescent diaphragm inside edge, with the crescent diaphragm positioned at same
On horizontal plane, the extension plate is identical as the central axis of crescent diaphragm, and the extension plate is duck-bill type structure, the extension
The height 5 of plate central axial direction and the ratio of height 4 of crescent diaphragm central axial direction are 1.8:1, and the crescent is thin
The two sides of diaphragm are symmetrically arranged with several diamond shape apertures 6 fixed convenient for beak before forming clip, the center of ipsilateral each diamond shape aperture
It is located in a straight line, each aperture edge is equipped with quoit 7 and is used to reinforce to prevent from tearing.
In use process, when Proximal caries badly reach 2-4mm under gum, dental caries are bad deeper, and matrix band is placed in proximal surface when operation,
Complete interim hole wall, filling layered filling can be formed.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
