Description

Device for pouring oral cavity model

Technical Field

The utility model belongs to the technical field of the mouth rehabilitation, concretely relates to oral cavity model fills uses device.

Background

At present, in the department of stomatology, a full denture model is infused with a surrounding membrane method and a general infusion method, and the surrounding membrane method is rarely used in clinic due to quite complicated operation and is not repeated.

Generally, the perfusion method is to pour plaster on a glass plate, turn the perfused impression over the glass plate, lightly adjust the impression by hand so that the maxillofacial surface of the impression is parallel to the glass plate, the thickness of the edge of the model is preferably 3-5 mm, the thinnest part of the model cannot be less than 10mm, the rear edge of the maxilla model is not less than 2mm in the small palate place, the lower jaw model is not less than 10mm from the front edge after grinding teeth, in order to make the model have the shape of the turning part of the mucosa, the plaster is covered by a mixing knife by about 3mm around the impression, and the surplus plaster at the edge is removed.

To general perfusion method, after the die upset, the gypsum of bottom can cave in downwards because of the effect of gravity for the thickness of jaw face to model bottom can't reach the requirement, simultaneously, when crossing die periphery edge with the knife of mixing with the accent, often need cover the gypsum all around the die with the slow rotation of glass board, and in the time of rotatory, the base just sinks very easily, on the other hand, if the irrotational glass board, then the staff who will pour into the model removes the health, very trouble.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, the utility model aims to provide a fill more accurate efficient oral cavity model and use device.

The utility model discloses a following technical scheme realizes:

the device for pouring the oral cavity model is characterized by comprising a rotating device and a bottom support which is arranged separately from the rotating device, wherein the rotating device comprises a turntable and a supporting seat, and the top of the supporting seat is connected with the turntable through a bearing to realize the rotation of the turntable; the collet is upper end opening, all around and bottom confined silica gel casing, and the hollow structure of collet is used for placing of oral cavity die.

Furthermore, the bottom parcel of supporting seat has the silica gel slipmat.

Furthermore, the bottom supports comprise an upper jaw bottom support and a lower jaw bottom support, and the upper jaw bottom support and the lower jaw bottom support are respectively provided with three types, namely a large type, a medium type, a small type and a medium type.

Further, the shoe is placed directly onto the turntable, and the shoe has a wide portion and a narrow portion, which are oppositely disposed.

Furthermore, the sizes of the large, medium and small models of the upper jaw collet and the lower jaw collet respectively correspond to the large, medium and small models of the upper jaw oral impression tray and the lower jaw oral impression tray.

The utility model discloses a place the carousel with the collet on, in the collet will be placed in to the die that will fill, can improve the quality and the efficiency that the model filled greatly, effectively avoid the gypsum base problem of subsideing, make the model fill more accurate high-efficient.

Detailed Description

The present invention will be further described with reference to the accompanying drawings for better understanding of the technical solution.

As shown in fig. 1-3, the device for pouring oral cavity model of the present invention is mainly used for pouring complete denture model, and specifically comprises: the rotating device 1 and the bottom support 2 which is arranged separately from the rotating device 1 are arranged, wherein the rotating device 1 comprises a turntable 101 and a supporting seat 102, the top of the supporting seat 102 is connected with the turntable 101 through a bearing to realize the rotation of the turntable 101, in order to realize the stability of the turntable 101, the bottom of the supporting seat 102 is wrapped by a silica gel anti-slip pad 103, the rotating device 1 realizes that the turntable 101 rotates, and the specific internal structure is not described in detail.

Continuing to refer to fig. 2, collet 2 is the upper end opening, all around and bottom confined silica gel casing, the hollow structure of collet 2 is used for placing of oral cavity die, and have wide portion 201 and narrow portion 202, wide portion 201 and narrow portion 202 set up relatively, collet 2 divides upper jaw collet and lower jaw collet, upper jaw collet and lower jaw collet all are provided with three kinds of models big, middle and small, the size of three kinds of models big, middle and small of jaw collet and lower jaw collet corresponds three kinds of models big, middle and small of upper jaw oral cavity die tray and lower jaw oral cavity die tray respectively, three kinds of models of specific upper jaw collet do not: large size: length 100mm, width 80mm, medium size: length 90mm, width 70mm, small size: 75mm in length and 60mm in width; the three types of the lower jaw bottom supports are respectively as follows: large size: length 80mm, width 100mm, medium size: length 70mm, width 90mm, small size: 60mm long and 75mm wide. The height of the underwires of various models is 12mm, with the distance between the wide portion of the underwires to the narrow portion being long.

The utility model discloses during the use, on at first placing carousel 101 with collet 2 that corresponds, toward 2 inside gypsum that fill of collet, then will fill the impression upset place the gypsum on collet 2 on, recycle carousel 101's steady rotation, with oral cavity impression tray with the accent all around mix the sword with the gypsum cover around the tray edge can.

The device for pouring the oral cavity model can greatly improve the quality and efficiency of pouring the model, on one hand, the model can be poured according to a standard model, on the other hand, the model is convenient and quick when the base is piled, a worker does not need to move the body to adjust the model and worry about that the plaster base can sink, and meanwhile, the bottom support ensures the thickness of the plaster model, so that the inaccuracy of manual calculation and the insufficient thickness of the base caused by less plaster amount are greatly reduced; the problem of insufficient thickness caused by the collapse of the gypsum is also avoided.
