Description
Technical field
This utility model belongs to a kind of buccal impression instrument, specifically, is the double-deck dismountable pallet of a kind of buccal impression.
Background technology
Along with the pursuit of people to dental health and beauty, the quality that improves dummy also is a demands of social development.Die is the important foundation of mouth mending material accurately, does not have accurately die just can not produce suitable dummy.Pallet is the key factor that influences the die precision, the traditional tray of existing clinical use, be the shape of a hoof, the circular arc limit of this tray for buccal impression is provided with the U-shaped sidewall, the outer middle side part of this U-shaped sidewall is provided with the holder handle, middle part, described impression tray bottom surface projection is an arch, and this projection extends on the straight flange of rear end always, is distributed with circular hole on described tray for buccal impression bottom surface and sidewall.Find to have following four shortcomings in the process of the clinical use of this traditional tray: 1, a finished product tray for buccal impression respectively has nearly 50～60 of apertures, must will remain in impression material in the aperture etc. with probe during each the cleaning disposes, workload is huge, and be difficult for cleaning up, particularly hardness is big, the use of impression materials such as the silicone rubber that intensity is high, thiorubber. has more strengthened the cleaning difficulty, influences the clinical disinfection effect.2, impression material easily separates with pallet.3, demoulding inconvenience.Unnecessary impression material is to pharyngeal inflow when 4, getting maxillary impression, and vomiting reaction easily causes nausea.
The utility model content
Technical problem to be solved in the utility model is to provide the double-deck detachable tray for buccal impression of a kind of high accuracy, easy cleaning, the easy demoulding.
The technical solution of the utility model is as follows: the detachable tray for buccal impression of a kind of bilayer, tray for buccal impression is the shape of a hoof, the circular arc limit of this tray for buccal impression is provided with the U-shaped sidewall, the outer middle side part of this U-shaped sidewall is provided with the holder handle, middle part, described tray for buccal impression bottom surface projection is an arch, this projection extends on the straight flange of rear end always, on described tray for buccal impression bottom surface and sidewall, be distributed with circular hole, its key is: described tray for buccal impression below is provided with the base that coats this tray for buccal impression bottom surface and sidewall, and described base front end is provided with base handle.Impression material is contained on the tray for buccal impression, and the doctor holds base handle and holds tray for buccal impression by base, and this moment, material was pressed between pallet and base by aperture, treated behind the material solidification tray for buccal impression to be taken out.The perfusion Gypsum Fibrosum, open movable fastener tray for buccal impression after solidifying and be easy to separate with base, tear the impression material of this tray for buccal impression bottom rear, the die of molding just takes out easily, and model frangibility not.Unnecessary impression material flows to pallet and base during delivery, is difficult for to pharyngeal inflow, and vomiting reaction causes nausea.
The aperture of the circular hole on the above-mentioned tray for buccal impression is 3.0mm～4.0mm.In the hole, garden of about 32 of distributions on the tray for buccal impression, pallet cleans easily, and is quick.
The bottom surface and the inside sidewalls of above-mentioned base are provided with alignment pin.Alignment pin leaves the gap by tray for buccal impression and base, makes things convenient for impression material to flow into, and increases the maintenance power of material and pallet, improves the die precision thereby reduce material deformation.
Lateral symmetry is provided with two journal stirrups that inwardly turn over time on the above-mentioned base handle, and this journal stirrup is corresponding with described holder handle, and this journal stirrup and handle form the chuck that can entangle the holder handle.Above-mentioned base rear end is hinged with movable fastener respectively by the two side, and this activity fastener one end extends with base hinged, and described movable fastener can be clipped in the base plate of base and tray for buccal impression in the U-shaped opening of this activity fastener.All being for tray for buccal impression well is fixed in the base, is again a kind of demountable structure, takes out tray for buccal impression in order also to make things convenient for.
Beneficial effect: the utlity model has delivery precision height, clinical easy to use, cleaning and disinfection easily, the easily demoulding, model frangibility not during the demoulding, unnecessary impression material is difficult for being difficult for the vomiting reaction that causes nausea to pharyngeal inflow when getting maxillary impression.
