Description

[0001] Flask for denture [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a flask for denture production, and more particularly to a flask for manufacturing a denture, which can manufacture a plurality of dentures with a pair of flasks.

In general, restorations restored in the oral cavity are classified into fixed and removable. Fixed prosthesis is a prosthesis that can not be removed once it is set in the oral cavity. It is mainly made of precious metal, a crown covering the partially and completely missing tooth using ceramics, and a cavity formed after removing the partially corroded part. And the like. Removable restorations are collectively referred to as restorations that can be dismounted by the user in the oral cavity. They are mainly orthodontic appliances and dentures.

As a material for making such a denture, a metal or a resin is mixed according to the indication. For example, in patients with denture dysfunction, a frame made of metal is made on the residual teeth of the patients belonging to the denture indications, and the frame is put on the remaining teeth and restored using the resin only on the tooth missing part. In edentulous patients, since there are no remaining teeth, all the missing parts including the portion contacting the gum are restored with the resin. In some cases, the restorations made of metal are inserted into the restored resin.

Meanwhile, in order to manufacture the denture, a model in which the shape of the oral cavity is reproduced first is formed. The model is made by pouring gypsum on the impression body, which is modeled mainly in the oral environment. After placing the artificial tooth on the tooth missing part in the model of gypsum, the position is fixed by using wax. In addition, the part to be substituted with the resin is made into a shape using lead.

A mold is formed to replace the lead formed by resin with a resin, and a flask for denture production is mainly used. The lead is placed in a flask to form a mold, and then buried with a dental investment material such as a gypsum. Next, heat is applied to the flask to soften all the lead constituting the lead, and the resin is injected into the space where the lead is formed. When the resin is cured, the investment material is removed from the flask, and the investment material is removed to extract the molded denture.

An example of a method of producing a denture is disclosed in Korean Patent No. 10-1101564. According to the above-mentioned patent, manufacturing a main casting after making an in-mouth impression using an individual tray from an edentulous wax, preparing lead teeth by arranging artificial teeth after making an occlusal shape using wax from the main casting mold, The method of claim 1, wherein the gypsum is a mixture of gypsum and gypsum. 2. The method of claim 1, A step of curing the second buried gypsum after the second buried gypsum is cured, dissolving the wax in the molten glass in a hot water bath, and separating the upper and lower sides of the flask; Forming a fiber frame, transferring the resin to the upper and lower portions of the flask, curing the glass fiber frame to the top of the transferred resin A step of pressing and bonding the glass fiber and the resin after bonding the upper and lower portions of the flask, and a step of separating the denture from the flask after completion of the polymerization to complete the final denture after polishing and polishing , The step of fabricating the cured glass fiber frame using the master casting includes: applying a wax separating agent to the master casting and then attaching a wax sheet; Piercing a plurality of holes in the wax sheet and filling the pores with partial resin; Disposing a glass fiber in the form of a mesh on the top of the wax sheet; Inserting the main mold in which the glass fibers are arranged into a vacuum apparatus, and pressing the main mold in a vacuum state; Curing the glass fiber in a vacuum lamp; And immersing the master mold in which the glass fiber is hardened in a hot water to dissolve the wax sheet, and then separating the hardened glass fiber from the master mold.

However, in the above-mentioned patent, when the denture is manufactured, the process of separating the upper and lower parts of the flask is performed. In this case, when the process of separating the upper and lower parts is performed, It is not easy to re-assemble the upper and lower teeth, and a minute error occurs between the upper and lower teeth structurally. As a result, the final denture due to the error does not fit well in the oral cavity of the patient.

In addition, in the above-mentioned patent, only a single denture can be manufactured with a pair of flosses composed of an upper and a lower dent in the process of producing the denture. That is, in order to produce a large number of dentures, the number of dentures to be manufactured must be equal to the number of dentures to be manufactured, and it is cumbersome to repeat the process by the number of dentures to be manufactured. Therefore, the conventional flask has a problem that the productivity is significantly lowered in manufacturing a large number of dentures.

The effects of the denture flask according to the present invention are as follows.

Firstly, different lead values can be buried in the upper and lower ends, respectively, so that one or more dentures can be made through a pair of flasks. Therefore, the effect of increasing the productivity can be seen.

Secondly, it is possible to use a conventional flask which can be manufactured only with one dent in combination, and to work efficiently according to the number of dentures to be manufactured. In addition, a large number of dentures can be manufactured without a flask Economic effect can be seen.

Third, it is possible to omit the process of separating the lower and upper parts from each other in the process of manufacturing the denture, and thus it is possible to prevent the volume of the finally produced denture from being deformed.

Fourth, by providing the insulation of the resin, the resin can be uniformly thermally polymerized from the opposite direction in which the artificial teeth are located, that is, the direction of the gypsum model, at the time of polymerization of the resin, so that the outer shape of the denture can be prevented from being deformed by polymerization shrinkage, The surface porosity due to the polymerization shrinkage can be suppressed. Thus, the patient wearing the denture can wear the denture fitting well in the oral cavity, the strength of the denture is decreased due to the surface porosity, the denture is broken, There is an effect that the disease can be prevented from occurring.

Fifth, since the resin can be injected in one direction toward the mold due to the check valve installed at the injection port into which the resin is injected into the mold, the resin can be prevented from flowing backward in the reverse direction of the flask when injecting resin.

Sixth, the number of lead teeth that can be buried in the artificial tooth receiving portion due to the inferior, inferior, and middle teeth extending to both ends increases, thereby increasing the productivity.

The main body 500 includes a main body 510, an artificial tooth receiving portion 520, a separating groove forming portion 530, a heavy input port 540 and a gypsum input port 550.

The central body 510 constitutes the body of the middle 500 and the artificial tooth receiving portion 520 penetrates the middle body 510 up and down to form the buried spaces 300 and the buried spaces 311 and 411 of the upper body 400, As shown in FIG. 5B, one space is formed between the lower portion 300 and the buried spaces 311 and 411 of the upper portion 400, as shown in FIG. 5B.

In addition, at least one separation groove forming portion 530 is formed to protrude along the inner peripheral surface of the artificial tooth receiving portion 520. More specifically, as shown in FIG. 6, the separation groove forming part 530 is formed to protrude at an interval in the inward direction of the artificial tooth receiving part 520 and extend in the vertical direction of the middle body 510.

The middle inlet 540 is formed at one side of the middle body 510 so that at least one of the high-pressure steam and the resin can be introduced into the artificial-tooth receiving portion 520. In addition, it is preferable that a check valve V 'is installed in the middle inlet 540 so that the resin can be injected in one direction.

More specifically, as shown in FIG. 5C, the denture of the lead material is softened by the high-pressure steam introduced into the heavy input port 540 and can be discharged to the lower discharge port 430 and the lower discharge port 330, respectively, , A residual amount may be discharged after the resin charged in excess into the middle injection port 540 completely fills the mold M '.

The gypsum input port 550 is formed to penetrate the outer circumferential surface of the middle body 510 toward the artificial tooth receiving portion 520 so that the gypsum can be injected into the artificial tooth receiving portion 520. 1 and 5B, the gypsum inlet 550 is formed by injecting gypsum toward the artificial tooth receiving portion 520 in a state where the upper body 400, the lower body 300 and the middle body 500 are coupled to each other, As shown in Fig. That is, in order to inject gypsum into the inside of the flask 20, a gypsum powder mixed with water is injected toward the gypsum inlet port 550 to fill the buried spaces 311, 411 and the artificial- have.

 Therefore, the plaster W1 'W2' is primarily buried (first buried) in the buried spaces 311 and 411 of the lower 300 and the upper 400, 5b, after joining the bosses 400, 300 and 500, the gypsum is injected (secondarily buried) into the gypsum inlet port 550, and the inside of the flask 20 is poured Make sure to fill it all.

Meanwhile, as shown in FIGS. 5 to 6, at least one middle fastener 513 penetrating from the upper surface to the lower surface may be formed in the middle body 510. The upper body 410 and the lower body 310 adjacent to the middle body 510 are respectively formed with upper and lower fasteners 413 and 313 so as to communicate with the middle fastener 513. More specifically, when the bosses B 'are engaged with the upper fasteners 413, the lower fasteners 313, and the middle fasteners 513 when the bosses 400, the hammers 300, And the nut N 'which is inserted into one side and fixes the bolt B' to the other side is fastened, thereby firmly supporting the assembled state between the two.

Hereinafter, a method of manufacturing a denture according to a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

5A, the position of the lead W1 'is fixed in the casting space 300 by placing the lead W1' filled with the gypsum at a predetermined height in the buried space 311 of the lower portion 300, . After the gypsum is filled at a predetermined height in the buried space 411 of the upright 400, the lead W2 'is embedded in the buried space 411 to fix the position of the lead W2' The lead teeth W1 'and W2' are buried (first buried) in the underbody 300 and the bump 400, respectively (S210).

5B, the upper surface 400, the lower surface 300, and the middle 500 are coupled (S220), the surface of the lead W1 'having the primary buried in the lower surface 300, (I ') < / RTI > In addition, a discharge passage O 'is formed to connect the surface of the lead W1' with the discharge outlet 330.

At the same time, an injection path I 'connecting the surface of the lead W2' with which the primary burial is completed to the upper injection port 430 is formed in the upper part 400. In addition, a discharge passage O 'connecting the surface of the lead W2' with the discharge port 430 is formed. At this time, the injection path (I ') and the discharge path (O') are formed of a lead material such as a denture-shaped material.

In addition, the gypsum is injected into the gypsum input port 550 in a state where the upper, lower, and central 500 are coupled to fill the empty space of the artificial-tooth receiving portion 520 with gypsum (secondary buried) (S230).

As shown in FIG. 9C, the check valve V 'is coupled to the middle injection port 540, and the high pressure steam is injected into the lower and the upper chambers 300 and 400 (S240). At this time, the check valve V 'allows the resin to be injected in one direction toward the mold M'. That is, the check valve V 'can be constructed by adopting various structures so as to prevent the resin from flowing backward when the resin is injected.

The dent of the lead W1 'and W2' buried in the lower 300 and the upper 400 is softened in the high pressure steam and discharged to the outside through the lower discharge outlet 430 and the lower discharge outlet 330. In addition, the injection path (I ') and the discharge path (O') formed of a lead material are also softened and discharged. Therefore, the mold M 'is formed at the position where the lead teeth W1' and W2 'are formed.

5D, the resin is injected into the mold M 'through the check valve V' provided in the middle injection port 540 (S250). When the injection of resin into the mold (M ') is completed, the cavity is placed in the warmer stage to polymerize the resin.

At this time, the resin used for the preparation of the denture may be a thermoplastic resin that initiates polymerization reaction by heat, and a thermoplastic resin which can be plasticized by heating but reversibly hardened by cooling may also be used. That is, the heat polymerization resin can be polymerized through the step of adding heat and the thermoplastic resin can be cooled at room temperature to complete the polymerization. The present invention can be used in combination with the thermopolymerization and the thermoplastic resin, and for the convenience of explanation, a method of manufacturing the denture by employing the heat polymerization resin will be described.

The above-mentioned on-state machine is a concept of a constant temperature bath, and the temperature and the polymerization time of water can be adjusted according to the type of resin used. The resin starts polymerization reaction from the direction of receiving heat. Generally, when the upper and lower molds 400 and 300 are all made of a metal material and thermally polymerized, the mold M 'absorbs heat as a whole, so that polymerization reaction occurs irregularly in all directions of the polymer to be polymerized, M '), or there may be fine porosity inside. However, since the dental flask for manufacturing denture according to the present invention is provided with the central part 500 of the heat insulating material, the resin can be uniformly thermally polymerized from the direction opposite to the position of the artificial tooth, that is, the direction of the gypsum model at the time of polymerization, It is possible to prevent the outer shape from being deformed and to suppress the surface porosity due to irregular polymerization shrinkage. Thus, the patient wearing the denture can wear the denture fitting well in the oral cavity and the strength is decreased due to the surface porosity, Or prevent the oral disease from occurring due to the proliferation of bacteria.

As shown in FIG. 6, when the polymerization of the resin is completed, the dent 400 is disassembled and the dent 300 and the dent 500 are extracted to extract the denture (S260). At this time, to extract the denture, the flask 20 is disassembled as shown in FIG. 6 to extract the immersed body C before the gypsum is removed. In order to extract the denture from the immersion body (C), the immersion body (C) surrounding the denture is impacted with a rubber hammer or a drill to remove the gypsum.

13 is a half sectional view exemplarily showing a conventional denture making flask, in which the middle 500 of the first embodiment according to the present invention is inserted into the bumper 2, which is conventionally used in the form shown in Fig. 1, Can be used interposed therebetween.

More specifically, the conventional flask can be manufactured by burying only one lead (M ") in the lower and upper flanges (1) and (2). At this time, on one side of the upper body 4, there is provided an upper inlet 8 through which at least one of the high-pressure steam and the resin can be injected into the buried space 6, And at least one of the resin and the resin may be inserted into the buried space 5. At this time, the resin can be injected into the inside of the mold M '' through the upper injection opening 8 and the lower injection opening 7.

Therefore, it is possible to use the middle 500 in combination with the conventional flask, which is capable of manufacturing only one dent. Thus, it is possible to efficiently work according to the number of the dentures manufactured, and in addition, a large number of dentures can be manufactured So that the economic effect can be seen.

The first modified example of the first embodiment of the denture manufacturing flask according to the present invention will be described with reference to Fig. The above modification is the same as the first embodiment described above. However, the damper 300, the damper 400, and the damper 500 extend at both ends as shown in Fig. 7A. In addition, the edges at both ends are configured in the shape of a chamfering. As a result, the number of lead teeth W1 ', W2' that can be buried in the buried spaces 311, 411 and the artificial tooth receiving portion 520 is increased, and as a result, So that the productivity can be increased.

In addition, in a second modification of the first embodiment of the denture-making flask according to the present invention, as shown in FIG. 7B, the middle 500 can be used in half-divided form. More specifically, the middle 500 is divided into an upper middle 500a and a lower middle 500b, and the lower middle 500b and the lower 500b are separated from each other. The upper middle chamber 500a is used in combination.

When the injection path I 'is formed in the plurality of lead buried in the lower and upper ends 300 and 400 respectively, the lead wirings W1' , W2 ') and formed on the lead teeth to form the discharge path O', the stem starting from the respective lead teeth W1 'and W2' 330 to form a single discharge line O '.

Hereinafter, a second embodiment of the denture flask according to the present invention will be described with reference to the accompanying drawings. FIG. 8 is an exploded perspective view showing the overall appearance of a second embodiment according to the present invention, FIG. 9 is an exemplary half sectional view of a second embodiment according to the present invention, and FIG. 10 is a cross- And FIGS. 11A, 11B, 11C and 11D are exemplary half sectional views of a second embodiment according to the present invention. The same or similar parts as those of the first embodiment described above will not be described in detail in order to avoid redundancy.

As shown in FIGS. 8 and 9, the second embodiment of the denture manufacturing flask according to the present invention is largely composed of the bumper 200 and the bumper 100. At this time, the state in which the upper casing 200 and the lower casing 100 are coupled to each other will be referred to as a flask 10.

Different lead values W1 and W2 are buried in the upper and lower casings 200 and 100, respectively.

More specifically, the lower casing 100 includes a lower main body 110, a lower casing 120, and a lower casing 130. At this time, the lower main body 110 constitutes the body of the lower casing 100, and the buried space 111 in which the lead W1 is buried is formed. In addition, the lower inlet 120 is formed at one side of the lower main body 110 so that at least one of the high-pressure steam and the resin can be injected into the buried space 111. In addition, the lower discharge port 130 is formed through the other side of the lower body 110 so that the softened lead and the excessively charged resin can be discharged.

The upper 200 is symmetrically coupled to the lower 100 in the same shape as the lower 100 and includes an upper body 210, At this time, the upper body 210 constitutes the body of the upper case 200, and the buried space 211 in which the lead W2 is buried is formed. The upper injection port 220 is formed on one side of the upper body 210 so that at least one of the high pressure steam and the resin can be injected into the buried space 211. The lower discharge port 230 is formed through the other side of the upper body 210 so that the softened lead and the excessively charged resin can be discharged.

That is, the lower discharge port 130 and the lower discharge port 230 are configured such that the dent of the lead material is softened and discharged by the high-pressure steam introduced through the upper discharge port 220 and the lower discharge port 120.

11A, the buried spaces 111 and 211 are formed so that the height of the lead teeth W1 and W2 can be adjusted so that the lead teeth W1 and W2 can be completely housed in the upper and lower cases 200 and 100, respectively, .

More specifically, reference symbol A in FIG. 11A denotes an interval between the upper edge of the lower edge 100 and the upper edge 200 and the annual values of the lead values W1 and W2 buried in the buried spaces 111 and 211 , And A is preferably formed at intervals of 2 to 5 cm.

If A is less than 2 cm, there is a fear that the positions of artificial teeth of the lead teeth W1 and W2 buried in the buried spaces 111 and 211 are changed by the resin injection pressure in the resin filling step described later, The gypsum used as the investment material is used in a large amount, which is not economical.

This is a major feature of the second embodiment according to the present invention, in which the upper teeth 200 and the lower teeth 100 are coupled to each other by completely housing the lead teeth W1 and W2 in the buried spaces 111 and 211 One or more dentures can be made through a pair of flasks 10.

The fastening method using bolts and nuts may be used to firmly support the assembled state of the bosses 200 and the hammers 100. However, the present invention is not limited to this, and various methods other than the bolt- have. For example, as shown in FIG. 8, at least one lower fastener 113 may be formed in the lower main body 110 so as to penetrate from the upper surface to the lower surface. Further, the upper body 210 is formed with an upper fastening hole 213 communicating with the lower fastening hole 113. The bolt B is inserted into one side of the upper fastener 213 and the lower fastener 113 and the bolt B is fastened to the other side when the upper 200 and lower 100 are coupled to each other. The nut (N) is fastened.

Hereinafter, a method of manufacturing a denture according to a second embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 11A, after the gypsum is filled at a predetermined height in the buried space 111 of the lower vessel 100, the position of the lead W1 is fixed in the lower vessel 100 by placing the lead W1 in the gypsum . After the gypsum is filled in the buried space 211 at a predetermined height, the lead W2 is embedded in the gypsum 100 to fix the position of the lead W2 within the bump 200, And the lead wires W1 and W2 are buried (primary buried) in the bump 200 (S110).

In addition, an injection path (I) for interconnecting the surface of the lead (W1) whose first burial is completed in the lower vessel (100) and the lower vessel inlet (120) is formed. In addition, the discharge path O interconnecting the surface of the lead W1 and the discharge outlet 130 is formed.

At the same time, an injection path (I) for interconnecting the surface of the lead (W2) with which the primary burial is completed in the upper part (200) and the upper injection port (220) is formed. In addition, a discharge path O interconnecting the surface of the lead W2 and the bore outlet 230 is formed. At this time, the injection path (I) and the discharge path (O) are formed of a lead material such as a lead material.

11B, the gypsum is injected into the upper portions of the lead pins W1 and W2, which are first buried in the lower portion 100 and the upper portion 200, thereby filling the buried spaces 111 and 211 with each other ). At this time, the secondary burial proceeds after the gypsum used in the primary burial is cured. At the same time, the damper 100 and the dam 200 are coupled. At this time, the lower 100 and the upper 200 are coupled to each other in a form facing each other (S120).

The check valve V is coupled to the coupling port P1 integrally formed with the lower inlet 120 and the upper inlet 220 so that the lower inlet 100 and the upper inlet 200 are connected to each other. Pressure steam is injected into the inner side (S130). At this time, the dent of the lead W1 and W2 buried in the lower 100 and the upper 200 is softened in the high-pressure steam and is discharged to the outside through the lower discharge outlet 230 and the lower discharge outlet 130. In addition, the injection path (I) formed of the lead material and the discharge path (O) are also softened and discharged. Thus, the mold M is formed at the position where the denture image was formed.

11D, the resin is injected into the mold M through the check valve V provided at the coupling inlet P1 (S140). In order to determine whether the resin has been completely injected into the mold M, the resin is injected into the joint discharge port P2, which is integrally formed with the lower discharge outlet 230 and the lower discharge outlet 130, until the resin is discharged .

Next, when the polymerization of the resin is completed, the denture is extracted from the upper and lower jaws 200 and 100 (S150).

Thus, one or more dentures can be fabricated through a pair of flasks 10.
