Abstract
The utility model relates to a disposable plastic dental impression tray for lower teeth, which is characterized by comprising a plastic tray and a plastic handle horizontally connected to the middle of an outer frame of the tray. The plastic tray is a U-shaped bent groove which can contain a lower dental arch. The U-shaped bent groove comprises a U-shaped bottom surface, an inner frame and an outer frame. The inner frame and the outer frame are tucked up along the inner edge and the outer edge of the U-shaped bottom surface. A notch is disposed in the middle of the outer frame, and the height of the outer frame is gradually decreased from both sides of the notch to the front ends of both sides of the tray. Through holes are evenly distributed on the U-shaped bottom surface and the outer frame. Thin and long triangular holes are arranged on the inner frame. Strengthening ribs are installed on the edges of the plastic handle and at the bent portion of the back of the bottom surface of the plastic tray. The disposable plastic dental impression tray for lower teeth is made of non-toxic acrylonitrile-butadiene-styrene (ABS) material by means of one-time injection molding. The tray and the handle are firmly combined with high strength, produced teeth marks of the dental impression are clear, and the disposable plastic dental impression tray for lower teeth is light in weight, comfortable to use, hygienic, and low in cost.
Description
Technical field
This utility model relates to a kind of dentist and is manufacturing the instrument that the tooth plaster model is used, and relates in particular to the disposable dental impression silica end opening of a kind of plastics pallet.
Background technology
Dental impression tray is that the oral cavity dentist is making the employed instrument of tooth model to the odontopathy patient.At present the dentist adopts metal material to make in employed dental impression tray, and complex process is easily got rusty, the cost height, and is difficult for sterilization, and handle and pallet easily come off.
The utility model content
Technical problem to be solved in the utility model be at above-mentioned existence not enough and provide a kind of pallet and handle in conjunction with firmly, intensity is good, economy, health, comfortable, the tooth section die teeth mark of making is the disposable dental impression silica end opening of plastics pallet clearly.
This utility model is to address the above problem the scheme of being taked to be:
The plastic handle that includes plastic pallet and engage with pallet outer rim middle part level, described plastic pallet be can ccontaining lower dental arch the curved groove shape of " U " type, the curved groove of described " U " type comprises " U " type bottom surface and interior frame and the outer rim turned up along outer edge in " U " type bottom surface, the outer rim middle part is provided with recess, and the height of outer rim successively decreases from recess two side direction pallet both sides front ends, be evenly distributed with through hole on " U " type bottom surface and the outer rim, all there is to be provided with elongated delthyrium described plastic handle edge on the interior frame, the bending part at back, plastic pallet bottom surface all is installed on reinforcement.
Press such scheme, the tray bottom surface back of the disposable dental impression silica end opening of described plastics pallet is provided with " eight " font reinforcement along tray centerline.
Press such scheme, the curved groove bottom termination of described " U " type is an angle, and angle is from inside to outside towards rear-inclined.
Press such scheme, the outer rim of the curved groove of described " U " type is vertical with the bottom surface, and the angle of interior frame and bottom surface is 95-110 °, relatively U " the curved groove bottom flare of type.
Press such scheme, the through hole on the described plastic pallet is circular, porosity 〉=50%.
Press such scheme, the disposable dental impression silica end opening of described plastics pallet obtains by single injection-molded.
Press such scheme, the disposable dental impression silica end opening of described plastics pallet adopts the non-toxic ABS material to form.
The beneficial effects of the utility model:
The disposable dental impression silica end opening of these plastics pallet adopts non-toxic ABS material single injection-molded, and pallet and handle are in conjunction with firm, and intensity is good, and modeling composition and trays are firm, and the tooth section die teeth mark of making is clear; In light weight, use comfortable, health, cost low.
Description of drawings
Fig. 1 and Fig. 2 are the disposable dental impression silica end opening of plastics support holder structure sketch map.
The specific embodiment
Further specify summary of the invention of the present utility model below in conjunction with accompanying drawing.
The disposable dental impression silica end opening of plastics pallet, the handle 2 that includes plastic pallet 1 and engage with pallet outer rim middle part level, described pallet be can ccontaining lower dental arch the curved groove of " U " type, the curved groove of described " U " type comprises " U " type bottom surface and interior frame and the outer rim turned up along outer edge in " U " type bottom surface, outer rim is vertical with the bottom surface, the middle part is provided with recess, and the height of outer rim successively decreases from recess two side direction pallet both sides front ends, the angle of interior frame and bottom surface is 95-110 °, " U " type is bent the groove bottom flare relatively, the curved groove bottom termination of " U " type is an angle, and angle is from inside to outside towards rear-inclined.Be evenly distributed with manhole 3 on the bottom surface of the curved groove of " U " type and the outer rim, porosity 〉=50%, all have on the interior frame and be distributed with elongated delthyrium 4, the bending part at described handle edge edge and tray bottom surface back is equipped with reinforcement 5, the tray bottom surface back is provided with " eight " font reinforcement 6 along tray centerline, and the disposable dental impression silica end opening of described plastics pallet adopts non-toxic ABS material single injection-molded and obtains.
In use, the dentist puts into the disposable dental impression silica end opening of plastics pallet with modeling composition earlier, and modeling composition is penetrated into pallet with holes, makes modeling composition and trays together; The dentist holds the handle of the disposable dental impression silica end opening of plastics pallet then, the disposable dental impression silica end opening of the plastics that modeling composition is housed pallet is put into the patient oral cavity, interlocking by the patient, allow patient's teeth mark be formed on the modeling composition, the pallet that will be printed on dental cast again takes out from the patient oral cavity and gets final product.
