Abstract

The utility model discloses an oral direct forming tray material individually, including the wax lining of laminating in the finished product tray, the plastic membrane of laminating on wax lining upper surface and the photocuring resin piece of laminating on plastic membrane upper surface. The utility model has the advantages of reduce the number of times that the patient sees a doctor, save the required consumptive material of primary impression and primary model, reduce the cost of manufacture.

Description

Individual tray material formed directly in mouth

Technical Field

The utility model relates to a complete mouthful of artificial tooth restoration technical field, concretely relates to direct shaping tray material individually in mouth.

Background

When a patient without a jaw (without natural teeth in the mouth) carries out complete denture repair, a final model needs to be manufactured, and the process of manufacturing the final model specifically comprises the following steps: step 1, a primary impression is firstly made by a patient for the first visit and a finished tray, and a common white gypsum model is poured to be called as a primary model; step 2, filling and drawing lines on the initial model, and then manufacturing an impression tray suitable for a patient by using a light-cured resin sheet (or self-cured resin), namely an individual tray; and 3, performing a second visit of the patient, performing edge plastic treatment by using individual trays, preparing a fine impression, namely a final impression, and then pouring an ultrahard plaster model, namely a final model or a working model (hereinafter, collectively referred to as a final model). And finally, manufacturing complete dentures on the final model.

Therefore, the patient without the tooth jaw obtains a final model, the number of times of treatment is large, the manufacturing process is complicated, and the manufacturing cost is high.

SUMMERY OF THE UTILITY MODEL

For overcoming the defects of the prior art, the utility model aims to provide an intraoral direct molding individual tray material which can reduce the times of patient treatment, save the initial impression and the initial model material and reduce the manufacturing cost.

In order to achieve the above object, the utility model adopts the following technical scheme:

an individual tray material of an intraoral direct type comprises a wax lining attached in a finished tray, a plastic diaphragm attached on the upper surface of the wax lining, and a light-cured resin sheet attached on the upper surface of the plastic diaphragm.

Further, the shape and the size of the wax lining, the plastic diaphragm and the light-cured resin sheet are the same.

1) The utility model directly makes individual tray in the mouth of the patient, so that the final impression can be made when the patient is in a first visit, compared with the prior art, the patient has fewer visits and one time, and the operation processes of the initial impression and the initial model perfusion are saved; the method has the advantages of reducing the times of patient treatment, saving the consumables required by the initial impression and the initial model and reducing the manufacturing cost;

2) the utility model effectively supports the light-cured resin sheet through the wax lining, and simultaneously can effectively prevent the light-cured resin sheet from being adhered to the finished product tray;

3) the utility model discloses a set up the plastics diaphragm between wax lining and light-cured resin piece, effectively prevent light-cured resin piece and the adhesion of wax lining, the light-cured resin piece after the solidification of being convenient for takes off from the wax lining smoothly.

Drawings

FIG. 1 is a schematic structural view of the whole material of the present invention;

in the figure: 1-wax liner, 2-plastic diaphragm, 3-light-cured resin sheet.

Detailed Description

The present invention will be described in further detail with reference to the following specific examples, which should not be construed as limiting the invention.

As shown in fig. 1, the present invention provides an individual tray material formed directly in mouth, which comprises a wax liner 1 attached to the inside of a finished tray, a plastic membrane 2 attached to the upper surface of the wax liner 1, and a light-cured resin sheet 3 attached to the upper surface of the plastic membrane 2.

The method for manufacturing the individual tray directly molded in the opening comprises the following steps;

step 1: the patient's alveolar ridge size is measured and a finished tray matching the patient's alveolar ridge is selected.

Step 2: taking the individual tray materials directly molded in the mouth, placing the individual tray materials on the finished tray in the step 1, pressing the light-cured resin sheets 3, the plastic membranes 2 and the wax linings 1 until the tray is tightly attached to the finished tray, and trimming off the excessive light-cured resin sheets 3, the plastic membranes 2 and the wax linings 1 by using scissors.

And step 3: putting the photo-curing resin sheet 3, the plastic diaphragm 2 and the wax liner 1 which are trimmed in the step 2 and a finished product tray into hot water at the temperature of 60-70 ℃ for 1-2 min for softening, screwing the materials into a patient mouth, compacting and screwing out; and marking the position, 2-3 mm away from the edge, of the screwed-out light-cured resin sheet 3, and cutting off the light-cured resin sheet by using a blade.

And 4, step 4: and (3) putting the photo-curing resin sheet 3 cut off in the step (3), the wax lining 1, the plastic diaphragm 2 and the finished product tray into a photo-curing lamp for curing for 3-5 min, tilting the photo-curing resin sheet 3 from the wax lining 1 by using a blade after curing, and adding a handle to the tilted photo-curing resin sheet to obtain the individual tray directly molded in the mouth.

In summary, by using the material for forming individual trays directly in the mouth, individual trays can be directly formed in the mouth when a patient is first seen and the final impression can be obtained by using the trays. Thus, the patient can complete the final impression with only one visit. The procedure of primary impression and perfusion of the primary model can also be omitted. Not only reducing the times of patient's treatment, but also saving the consumables required by the initial impression and the initial model, thereby reducing the manufacturing cost.
