Description

Complete denture initial impression tray

Technical Field

The utility model relates to the field of medical equipment, concretely relates to complete denture initial impression tray.

Background

At present, when a full-mouth primary impression is prepared, the most adopted method is a mode of taking a impression by using alginate impression material after covering red paste with a non-porous aluminum tray, the operation of the method is complex, the hardness of the red paste is high, and no pores exist, when the impression is taken by using alginate, overlarge pressure can be generated on mucous membrane plica of an alveolar ridge and a mandibular molar posterior pad area, the edge of the impression material is excessively extended and extruded, and the impression requirement of the modern non-pressure adsorptive full-mouth denture cannot be met. Therefore, there is a need for a denture impression tray that overcomes the disadvantages of excessive pressure and excessive pressure-and-extension of the edge of the impression material that can occur when using such trays.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a complete mouthful of artificial tooth preliminary impression tray, this tray can be fast accurate prepare the pressure-free complete mouthful of preliminary impression tray, and the edge extends suitably, is difficult for the drawing of patterns, with respond well.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a complete mouthful of artificial tooth preliminary impression tray, includes tray and handle, the tray includes upper jaw tray and lower jaw tray, upper jaw tray and lower jaw tray all include U type tray body, are equipped with two parallel strengthening ribs in the bottom of U type tray body, are equipped with the even through-hole of a plurality of intervals between two strengthening ribs, two circular ports of symmetry are left at the U type tray body top of lower jaw tray.

Preferably, the diameter of the circular hole is 4mm ~6mm, the upper edge width of the circular hole is 2mm ~3 mm.

Preferably, a plurality of overflow holes are further formed in the outer side of the reinforcing rib and on the side wall of the U-shaped tray body.

Preferably, two cylindrical bulges which are symmetrical left and right are further arranged on the two reinforcing ribs.

Preferably, the U-shaped tray body is made of a thermoplastic material.

In the technical scheme, the two reinforcing ribs at the bottom of the tray can not only enhance the overall strength of the device, but also form a plurality of through holes between the two reinforcing ribs, so that the alginate impression material can quickly overflow, no excessive pressure is generated on the alveolar ridge mucous membrane plica, and the pain caused by use after the embedding is reduced; the alginate impression material can conveniently overflow through the circular hole and coat the large circular hole to fix the edge, so that excessive pressure is not generated on the post-molar cushion area, the alginate impression material is fully expanded, the area can be completely covered, and the alginate impression material is firmly fixed with the base and is not easy to demould; the cylindrical protruding part is suitable for fingers to provide more stable, balanced and uniform force when the impression is taken, so that the overflow of the impression material is more uniform and smooth, the stress of mucous membranes is consistent, and the pressure bearing is stable; the overflow hole can ensure that the impression material is better retained and is not easy to demould; the U-shaped tray body is made of thermoplastic materials, and the size of an arch and the width of an alveolar ridge can be adjusted more conveniently by the aid of the thermoplastic function of the U-shaped tray body.

Drawings

Fig. 1 is a schematic view of a maxillary tray structure;

fig. 2 is a schematic view of the mandibular tray structure.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 and 2, the complete denture initial impression tray comprises an upper jaw tray 1 and a lower jaw tray 2, wherein the upper jaw tray and the lower jaw tray both comprise a U-shaped tray body 3 and a handle 10, two parallel raised reinforcing ribs 4 are arranged at the middle position of the bottom of the U-shaped tray body 3, a plurality of through holes 5 with uniform intervals are reserved between the two reinforcing ribs 4, the through holes 5 can enable an alginate impression material to rapidly overflow, no excessive pressure is generated on alveolar ridge mucous membrane plica, and the pain caused by use after the embedding is reduced.

A plurality of strip-shaped overflow holes 6 are reserved on the two sides of the reinforcing ribs 4 and on the side wall of the U-shaped tray body, the overflow holes 6 can allow the impression material to pass through and cover the positions near the overflow holes 6, the retention effect of the impression material can be enhanced after the impression material is solidified, and demolding is prevented.

Still be equipped with two cylindrical protrusion 7 of symmetry on strengthening rib 4, further, cylindrical protrusion 7 sets up middle part about U type tray, and protruding 7's inside is hollow structure, and cylindrical protrusion 7 can allow the user to press on two archs through the finger in operation process, can apply a more balanced even pressure, makes overflowing of impression material more even smooth, and the mucous membrane atress is unanimous, and the pressure-bearing is stable.

Be equipped with the circular port 8 of two symmetries in mandibular tray 2's U type tray body top department, circular port 8 is close to edge one side and makes the edge leave a narrower edge, in a preferred embodiment wherein, the diameter of circular port 8 is at 4mm ~6mm, the top edge 81 width of circular port is 2mm ~3mm, adjust the height of filling up after grinding one's teeth in a knife very easily when moulding hot like this, alginate impression material can be very convenient spill over cladding macropore fixed edge through the macropore, not only do not produce too big pressure to fill up the district after grinding one's teeth in a knife, and alginate impression material extension is abundant, can cover this region completely, with the firm difficult drawing of patterns of base stock retention.

Above-mentioned U type tray 3 all uses thermoplastic material in the manufacturing process, can carry out the adjustment structure of thermoplastic functionality according to different patient's oral cavity inner structure difference like this, makes it can be applicable to more patients, strengthens commonality and the convenience of using, reduce cost.

The embodiment is only an illustration of the concept and implementation of the present invention, and is not a limitation, and the technical solution without substantial transformation is still within the protection scope under the concept of the present invention.
