Description

Individual tray material directly molded in mouth and individual tray manufacturing method thereof

Technical Field

The invention relates to the technical field of complete denture repair, in particular to a material for forming an individual tray directly in a mouth and a manufacturing method of the individual tray.

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.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to provide an intra-oral direct molding individual tray material and an individual tray manufacturing method which can reduce the number of times of patient visits, save the initial impression and the initial model material and reduce the manufacturing cost.

In order to achieve the purpose, the invention adopts the technical scheme that:

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.

A method for directly forming individual tray material in mouth and manufacturing individual tray includes the following steps;

step 1: measuring the size of the alveolar ridge of the patient, and selecting a finished product tray matched with the alveolar ridge of the patient;

step 2: taking an individual tray tool material with an internal direct type, placing the individual tray tool material on the finished tray in thestep 1, pressing the light-cured resin sheet to enable the wax lining to be attached to the finished tray firmly, and trimming off the redundant light-cured resin sheet, the plastic membrane and the wax lining;

and step 3: putting the photo-curing resin sheet, the plastic diaphragm and the wax lining which are trimmed in thestep 2 and the finished product tray into hot water for softening, screwing the photo-curing resin sheet, the plastic diaphragm and the wax lining into a patient mouth together, compacting and screwing out; marking and cutting the screwed-out light-cured resin sheet at a position 2-3 mm away from the edge;

and 4, step 4: and (3) putting the photo-curing resin piece cut off in the step (3) together with the wax lining, the plastic diaphragm and the finished product tray into a photo-curing lamp for curing, taking down the cured photo-curing resin piece, and adding a handle to obtain the individual tray directly molded in the mouth.

Further, the temperature of the hot water in thestep 3 is 60-70 ℃, and the softening time is 1-2 min.

Further, the curing time in the step 4 is 3-5 min.

Compared with the prior art, the invention has the beneficial effects that:

1) according to the invention, individual trays are directly made in the mouth of a patient, so that a final impression can be made when the patient visits a doctor for the first time, compared with the prior art, the patient visits the doctor for one time less, and the operation processes of an initial impression and an 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 invention effectively plays a role in supporting the light-cured resin sheet through the wax lining, and can effectively prevent the light-cured resin sheet from being adhered to a finished product tray;

3) according to the invention, the plastic diaphragm is arranged between the wax liner and the light-cured resin sheet, so that the light-cured resin sheet is effectively prevented from being adhered to the wax liner, and the light-cured resin sheet after being cured can be conveniently and smoothly taken down from the wax liner.

Drawings

FIG. 1 is a schematic structural view of the entire 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 examples, which are not intended to limit the invention thereto.

As shown in figure 1, the invention provides a direct intraoral molding individual tray material, which comprises awax liner 1 attached in a finished tray, aplastic diaphragm 2 attached on the upper surface of thewax liner 1, and a light-curedresin sheet 3 attached on the upper surface of theplastic diaphragm 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 thestep 1, pressing the light-curedresin sheets 3, theplastic membranes 2 and thewax linings 1 until the tray is tightly attached to the finished tray, and trimming off the excessive light-curedresin sheets 3, theplastic membranes 2 and thewax linings 1 by using scissors.

And step 3: putting the photo-curing resin sheet 3, theplastic diaphragm 2 and thewax liner 1 which are trimmed in thestep 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-curedresin sheet 3, and cutting off the light-cured resin sheet by using a blade.

And 4, step 4: and (3) putting the photo-curingresin sheet 3 cut off in the step (3), thewax lining 1, theplastic diaphragm 2 and the finished product tray into a photo-curing lamp for curing for 3-5 min, tilting the photo-curingresin sheet 3 from thewax 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.
