Description

  The present invention relates to a method for manufacturing a denture having an artificial tooth and a denture base that supports the artificial tooth, and a denture.

A denture made of artificial teeth and a denture base is a necessity for those who have lost their teeth. In a nursing facility or a hospital where many wearers who wear a denture share a common life, the denture may be collectively managed, and it may be unclear who the denture belongs to. In addition, when a disaster occurs, identity verification may be performed from the remaining teeth, but if both the upper and lower jaws are full dentures, identity verification may not be obtained.
For such a case, a technique has been developed in which a wearer can be identified from a denture (see Patent Documents 1 to 3).

  The "denture" described in Patent Document 1 is printed or transferred with a specific person's identification display section such as name, address, date of birth, blood type, etc. on a dental crown continuation or denture. The floor surface containing

  Conventionally, “a plate denture, a method for producing a plate denture, and a resin plate used for a plate denture” described in Patent Document 2 are conventionally provided by an ink jet printer on the lingual side of the plate denture base. Although it was a method of printing the name, it was difficult to print clearly because it was printed on the denture base curved surface, the ink fixing power was weak, and the ink was rubbed in a relatively short period of time by brushing when cleaning Therefore, a transparent or translucent resin plate in which owner identification information is recorded is embedded and fixed at a predetermined position on the denture base.

  The "bed denture, name-giving method and denture and denture display sheet" described in Patent Document 3 partially soften the wax bed (gingiva) of the wax denture whose trial application has been completed by heating. In this softened area, a plurality of type letters are embedded in a parallel installation state, embedded in a flask, and the wax bed of the wax denture is melted in a state where the type letters are left in the same manner as the artificial teeth. The resin is pressurized and filled to give a name.

  First, in order to see the biting of the wearer, the occlusal floor on which the occlusal state of the wearer is recorded is prepared by placing the occlusal levee on a base floor (wax floor) formed of wax. The artificial teeth are arranged based on the occlusal floor in which the wearer's occlusion state is recorded. And, as described in Patent Document 3, the occlusal floor in which the artificial teeth are arranged is buried in the plaster of the flask, and after dewaxing the occlusal floor, the molding space is pressure-filled into the formed space. By doing so, the resin is molded as a denture base, and a base denture is produced.

Japanese Utility Model Publication No. 2-118551 JP 2001-340357 A JP 2003-180713 A

  In the conventional dentures described in Patent Documents 1 and 2, since the resin plate on which the printing and transfer or the owner identification information is recorded is buried in the denture base, at the stage of manufacturing the denture base The wearer cannot be identified.

In addition, in the conventional denture described in Patent Document 3, the name of the owner can be given from the beginning of the production of the denture by using the type, but the type is embedded in the trial fit. This is a wax denture wax bed (gingiva) that has been finished.
Therefore, the process from the creation of the foundation floor based on the impression model acquired from the wearer to the creation of the occlusion floor by placing the occlusal levee on the foundation floor cannot identify the wearer.

Therefore, if the denture base is not printed, transferred, or engraved, it may be mistaken for the denture base, but even if the denture base is printed, transferred, or engraved, There may be a difference in the foundation floor or impression model in the exchange with the engineer.
In particular, since dental dentures of different patients (wearers) are produced at the same time in dental clinics and dental laboratories, there are a large number of dentures in the process of production. Therefore, it is in a situation where mistakes are likely to occur.

  Then, an object of this invention is to provide the manufacturing method of a denture, and a denture which can prevent a mistake with the thing of another wearer in the manufacture process of a denture.

The method for producing a denture according to the present invention is a method for producing a denture to be worn by the wearer from a foundation floor formed on the basis of an impression model obtained from the wearer.

  According to the method for producing a denture of the present invention, since information on the wearer is given to the foundation floor formed based on the impression model, the occlusal floor is provided by providing an occlusal levee based on the foundation floor. Produce and record the occlusal state of the wearer, place artificial teeth based on the occlusal floor where the wearer's occlusion state is transferred to the occlusal levee, and then remove the occlusal ridge from the occlusal floor where the artificial teeth are placed When molding a denture base containing a base floor by filling with wax and flooring resin, the dentist and dental technician identify the wearer based on the information on the base floor and attach it to the wearer. The state can be adjusted and engineering work can be performed.

The method for producing a denture according to the present invention is a method for producing a denture to be worn by the wearer from a foundation floor formed on the basis of an impression model obtained from the wearer. A step of molding the foundation floor based on the impression model from a floor molding resin plate to be a floor, a step of providing information on the wearer to the information addition region of the foundation floor, and information on the wearer Providing an occlusal levee on the base floor to which the wearer is attached, and creating an occlusal floor for recording the occlusal state of the wearer; and on the occlusal floor where the occlusal state of the wearer is transferred to the occlusal levee A step of disposing an artificial tooth based on the step, a step of removing the occlusal levee from the occlusal floor where the artificial tooth is disposed, and a resin for a floor that becomes a gingival portion in the gap formed by dewaxing the occlusal levee Fill and mold the denture base including the foundation floor Characterized in that it comprises a step of a removable denture.

  Also according to the method for manufacturing a denture of the present invention, since information on the wearer is given to the foundation floor molded based on the impression model, an occlusal levee is provided on the basis floor to produce an occlusal floor The occlusal state of the wearer is recorded, the artificial tooth is placed based on the occlusal floor in which the occlusal state of the wearer is transferred to the occlusal levee, and the occlusal ridge is removed from the occlusal floor where the artificial tooth is placed. When filling denture base including base floor by filling with floor resin, dentists and dental technicians can identify the wearer based on the information on the base floor and make the wearer wear or occluded Can be adjusted.

Furthermore, the method for producing a denture according to the present invention is a method for producing a denture to be worn by the wearer from a base floor molded based on an impression model obtained from the wearer, wherein the impression the information addition area of the model, the step of applying information on the wearer, said from the underlying floor floor molding resin plate, and molding the base floor on the basis of the impression model, information giving the impression model A step of transferring information on the wearer assigned to the area to the foundation floor, and an occlusion for recording an occlusion state of the wearer by providing an occlusal levee on the foundation floor to which the information on the wearer is assigned A step of creating a floor, a step of placing an artificial tooth based on the occlusal floor in which the occlusal state of the wearer is transferred to the occlusal levee, and removing the occlusal ridge from the occlusal floor on which the artificial tooth is placed. The step of brazing and the bite The floor resin as a gingival portion voids Deki been wax is filled, characterized in that it comprises a step of a denture by molding a denture including the baseplate.

  According to the method for manufacturing a denture of the present invention, since the information about the wearer is given to the impression model, the wearer can be specified not only by the basic floor but also by the impression model.

After providing information on the wearer to the information providing area of the foundation floor, the method further includes a step of superimposing the light-transmitting floor molding resin plate as a cover floor on the floor molding resin plate serving as the foundation floor. be able to.
A denture base is formed by superimposing a cover floor formed of a resin sheet for floor molding on a base floor to which information on the wearer is given. Therefore, the cover floor protects information about the wearer attached to the foundation floor and covers the unevenness of this information, so that the information can be prevented from fading or scraping. It can be installed just like a complete denture.

  After applying the information, printing can be performed to flatten the unevenness of the information. By making the unevenness of the information flat, it is possible to obtain a denture with good tongue feel.

  If printing is performed to flatten the unevenness of the information, and the gap between the protrusions indicating the information is filled with ink, the height of the ink filling the gap between the protrusions indicating the information is aligned. Can be flat. Further, in the printing for flattening the unevenness of the information, when the concave portion indicating the information is filled with ink, the height of the concave portion indicating the information is equalized by the ink, so that the information can be flattened.

  In addition, when printing that flattens the unevenness of the information is made to cover the information with ink in accordance with the outline of the information, the ink becomes a flat surface and the ink is formed on the unevenness due to the convex portions and concave portions indicating information. Covering the cover can eliminate unevenness and make information flat.

  Further, when printing is performed to flatten the unevenness of the printing information so that the information is covered with ink so that the edge is inclined and is wider than the outline of the information, the edge by ink is gently inclined. Therefore, a step due to ink can be eliminated.

The pre Kijo paper application region, the a region where occlusion crest is provided, if the floor resin serving as the gingival portion formed of a light transmitting molded workpieces, since occlusion bank is gingival portion for supporting artificial teeth, basal Information given to the floor can be protected by the gingiva.

Before Kijo paper application region, the print information on the wearer when printing by the printing device as print information, the print information, ultraviolet or infrared using invisible ink and / or visible ink color to be illuminated can do.
By printing with visible ink, it is convenient because the contents can be grasped immediately. In addition, since printing is not easy since printing with invisible ink, it is effective because privacy protection can be enhanced when the degree of privacy is high, which is difficult to view easily.

  When the information about the wearer is given, when the information given to the upper floor for the upper jaw and the lower floor for the lower jaw are overlapped to give an integrated figure, the upper floor for the upper jaw Since the wearer can be specified as a set of the base floor for the lower jaw and the lower jaw, it can be prevented that they are mistakenly combined.

  When providing information about the wearer, even if information is provided that matches the shape when the base floor for the upper jaw and the base floor for the lower jaw are overlapped, the base floor for the upper jaw and the lower floor The wearer can be specified by setting the base floor as a set.

  With these methods for producing a denture, the denture of the present invention can be produced.

  In the present invention, the information about the wearer is given to the foundation floor of the denture that goes back and forth between the dentist and the dental technician from the preparation of the foundation floor to the stage of removing the occlusal levee to create the denture base. For this reason, it is possible to prevent mistakes from those of other wearers in the manufacturing process of the denture.

(Embodiment 1)
A method for manufacturing a plate denture according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 and 9. In the first embodiment, a case will be described in which an upper denture complete denture is produced even with a bed denture.

First, at the dental clinic, a dentist obtains a concave impression model from the oral cavity of a wearer wearing a denture, and performs an impression taking process for producing an impression model that is convex from the concave shape. (Step S10). This impression model is sent to the dental laboratory.
At the dental laboratory, the dental technician creates a concave mold again from the convex impression model, and further performs an impression model production process for producing an impression model M that is convex from the concave mold (step S20). .

Next, as shown in FIG. 2, the dental technician immerses the impression model M in the molten low melting point alloy 12 filled in the flask 11, and the molten low melting point alloy 12 is solidified to be fixed. A model fixing step is performed (step S30).
The bottom surface of the flask 11 is provided with a suction port for degassing, and the low-melting-point alloy 12 is contracted when the molten low-melting-point alloy 12 is solidified, and is solidified in a disk shape with the peripheral wall of the flask 11. A gap is formed between the low melting point alloy 12 and the surrounding wall surface.

  In this state, the dental technician performs a preparation process. In the preparation step, as shown in FIG. 3, a floor-molding resin plate P to be the base floor 21 is prepared (step S40). The floor molding resin plate P is a plate-shaped resin resin plate formed from a synthetic resin material, and the disk-shaped resin molding plate P may be purchased or has a pressing device. Alternatively, the dental technician himself may mold the resin plate P for floor molding.

  When the floor molding resin plate P is molded by a press device, the dental technician places a soft synthetic resin material in a cavity (molding space) formed by the upper mold and the lower mold and applies pressure. . Then, by hardening the softened synthetic resin plate whose outer shape is circular, the disc-shaped resin plate P for floor molding can be formed.

When the floor molding resin plate P is prepared, the dental technician performs an information providing process. The information providing step is a step of providing information about the wearer to the floor-forming resin plate P (step S50).
In the first embodiment, information relating to the wearer is printed as print information in the information imparting region of the floor-forming resin plate P by a printing device (not shown). An ink jet printer can be used as the printing apparatus.

For example, the floor molding resin plate P shown in FIG. 4 serves as the base floor of the denture for the upper jaw, and the information imparting region S of the floor molding resin plate P is the palate. In the information giving area S, the wearer's name, date of birth, and identification information for identifying an individual are printed as information (printing information W) about the wearer.
In addition to name and date of birth, information about the wearer includes personal information such as address, gender, blood type, hospital name that identifies the dental clinic that was treated, and a code identifying the hospital, family contact information, In addition to medical history, medication history, social history, family history, etc.

  In addition, since identification information for specifying an individual is printed, a name and date of birth are displayed on the resin sheet P for floor molding by searching based on the identification information from a database in which information about the wearer is registered. In addition, it can be obtained by searching without printing a wide range of information such as medical history, social history, family history, etc., which increases the number of characters and cannot be printed.

  For example, if the contact information of the family is the information about the wearer in addition to the name and date of birth, the wearer's identity can be immediately confirmed when the wearer suffers from dementia, and the family Can be contacted immediately, or when the wearer is authorized for treatment.

  As shown in FIG. 4, since the floor-forming resin plate P is plate-shaped, the printing surface by the ink jet printer is a flat surface. Therefore, it is possible to print the print information W composed of characters, symbols, etc. without distortion.

Here, the print information W to be printed in the information imparting region S of the floor molding resin plate P will be described in detail.
When printing information related to the wearer as print information in the information adding area S, the print information can be printed using visible ink. Visible ink is ink that is visible under an illumination device that emits sunlight or visible light. Further, the print information can be invisible ink that becomes colored when irradiated with ultraviolet rays or infrared rays. Further, the print information can be a combination of printing with visible ink and invisible ink. Useful printing information can be printed with visible ink if the contents such as name, gender, and date of birth can be grasped immediately. In addition, printing information with a high degree of privacy that is difficult to see easily can be printed with invisible ink, thereby enhancing privacy protection.

At this time, as shown in FIG. 5A, the characters and symbols (printing information W) printed on the floor molding resin plate P with the ink K1 are the ink K1 and the ink indicating the printing information W when viewed in cross section. K1 becomes a convex portion and protrudes from the resin resin sheet P for floor molding. There is a gap G between the inks K1 (convex portions). The unevenness caused by the ink K1 and the gap G has a poor touch.
Therefore, as shown in FIG. 5B, when the print information W is printed with the ink K1, the gap G is filled with another ink K2 that can be distinguished from the ink K1. By doing so, the height of the ink K1 indicating the print information W is equalized by the ink K2, so that the print information W can be made flat. By flattening the unevenness of the print information W, the entire print information W is free from dents, so that a denture having a good tongue feel can be obtained. The ink K2 that can be distinguished from the ink K1 is preferably a transparent ink.

  Further, as shown in FIG. 5C, the print information W is covered with another ink K3 having optical transparency in accordance with the contour of the print information W formed by the ink K1 and the gap G. Thus, by covering the print information W with the light-transmitting ink K3, the ink K3 becomes a flat surface, and the unevenness due to the ink K1 and the gap G is eliminated, so that the print information W can be flattened. Can have a denture with good tongue feel

  Further, as shown in FIG. 5D, the print information W is wider than the outline of the print information W formed by the ink K1 and the gap G, and the print information W is covered with the light-transmissive ink K4. The unevenness of is blocked. At this time, the ink K4 is printed so that the edge portion has a gentle inclined surface. By doing so, since there is no level difference of the ink K4, it is possible to make a denture with a better tongue feel.

Visible ink or invisible ink has no effect on the human body, and if the wearer has used the denture for many years, it will not be peeled off or thinned. There is no problem even in the state.
However, if there is a concern about the influence of the visible ink or the invisible ink on the human body, or peeling or fading due to the secular change, after printing information is printed using the visible ink or the invisible ink, FIG. As shown in (D), it is desirable to perform coating printing so that the entire print information W is completely covered.

Next, the dental technician performs a transfer process. In the transfer step, as shown in FIG. 6, the floor molding resin plate P softened by heating placed on the impression model M is pressurized and heated, and the shape of the impression model M is transferred to the floor molding resin plate P. (Step S60).
For this pressurization, for example, compressed air may be injected, or the floor-forming resin plate P may be pressed by another pressing device. When the compressed air is injected onto the floor molding resin plate P, the portion of the floor molding resin plate P larger than the contour of the impression model M is curved toward the peripheral wall side of the impression model M, and as shown in FIG. The entire floor-shaped resin plate P is deformed into close contact with the entire impression model M and is in close contact therewith.
When the shape of the impression model M is transferred to the floor-forming resin plate P, the dental technician arranges the floor outline with a handpiece drill or a raise. In this way, the foundation floor 21 can be produced.

  Next, the dental technician performs a basic floor removal process. In the foundation floor removal step, the foundation floor 21 attached to the impression model M is taken out from the low melting point alloy 12 in the flask 11, and the impression floor M is scraped or broken to remove the foundation floor 21 (step S70).

When the foundation floor 21 can be produced, the dental technician creates an impression model M again from the concave mold produced at the dental laboratory, and covers the foundation floor 21 on the impression model M. Next, the dental technician performs an occlusal bank formation process. In the occlusal levee forming step, as shown in FIG. 8, an occlusal ridge 22 (wax ridge) is formed by arranging a levee-like member at a tooth row position of the foundation floor 21 to produce an occlusal floor. As this bank-shaped member, for example, an existing wax bank made of arched paraffin wax can be used.
Thus, the occlusal acquisition denture 20 for upper jaws is produced by producing the occlusal floor in which the occlusal levee 22 is provided on the foundation floor 21 (step S80).

  In the above description, the manufacturing method of the upper jaw occlusal acquisition denture 20 has been described. However, the lower jaw occlusal acquisition denture can be manufactured in the same manner. When creating an occlusal denture for mandibular jaw, when forming the base floor, the tongue portion is cut and removed in a U-shape, so that the arch-shaped base floor for the mandible is disc-shaped. It can produce from the resin plate P for floor molding.

  When the occlusal acquisition denture 20 can be produced, the dental technician sends the occlusal acquisition denture 20 to the dental clinic. The dentist attaches the occlusal acquisition denture 20 in the oral cavity of the patient who becomes the wearer, and performs occlusal acquisition to record the occlusal state of the wearer on the occlusal acquisition denture 20 (step S90).

  When the patient bites, the crown portion of the occlusal bank 22 is deformed according to the occlusal state, and the occlusal state of the wearer is recorded in the occlusal acquisition denture 20. In addition, the dentist records the position of the median or occlusal plane on the lip side of the occlusal levee 22, thereby recording the occlusal state of the wearer on the occlusal acquisition denture 20.

When the patient's occlusion state is recorded in the occlusal acquisition denture 20 in this way, the occlusal acquisition denture 20 is sent to the dental laboratory. At the dental laboratory, the dental technician attaches the occlusal acquisition denture 20 to the articulator and adjusts the height and thickness of the occlusal ridge 22 while watching the occlusal ridge 22 meshing with the occlusal acquisition denture 20. However, after the occlusal ridge 22 is shaved and a space is secured, an artificial tooth arrangement process is performed in which a hard artificial tooth (not shown) formed by a resin tooth or porcelain or the like and imitating a tooth shape is attached instead. By this process, the artificial tooth is attached to the occlusal ridge 22 of the occlusal acquisition denture 20, and a molding denture whose height and thickness are adjusted so that the occlusal ridge 22 becomes a gingival part is produced (step S100).
The dental prosthesis is sent to the dental clinic, attached to the wearer, tested for the degree of completion, and returned to the dental laboratory. At the dental laboratory, final fine adjustment is performed according to the trial fit of the wearer.

When final fine adjustment is performed on the denture for molding, the dental technician removes the occlusal embankment 22 made of paraffin wax and replaces it with the resin for flooring used when molding the denture base, and hard gingiva. A molding process for molding the part is performed (step S110).
In the molding process, first, a denture for molding is placed in a lower flask filled with gypsum, filled with gypsum to be buried from above, and covered with a pair of upper flasks.

Next, the dental technician puts the pair of flasks in a heating furnace and heats them to melt and remove the occlusal levee 22. The base floor 21 does not melt and remains as a denture base as it is. A space formed by melting the occlusal levee 22 is filled with a resin for a floor serving as a gingival part.
Then, the dental technician is cured by a method according to the kind of the resin for flooring. For example, if the floor resin is a chemical polymerization type, it is polymerized at room temperature. Moreover, if it is a heat polymerization type, it is polymerized by heating. When the resin that becomes the gingival portion is cured, as shown in FIG. 9, the denture base 25 including the denture base 25 in which the gingival portion 23 is formed on the base floor 21 and the artificial tooth 24 supported by the gingival portion 23 is used. A complete denture 30 can be obtained.

  As described above, since information on the wearer is given to the foundation floor 21 in the dentures (occlusal dentures and molding dentures) that go back and forth between the dentist and the dental technician, the dentist and the dentist The engineer can attach the wearer and adjust the occlusal state while identifying the wearer based on the information on the foundation floor 21, so that it may be mistaken for that of other wearers. Can be prevented.

(Modification of Embodiment 1)
Next, the modification of the manufacturing method of the plate denture based on Embodiment 1 of this invention is demonstrated based on FIGS. 10-12.
In the modified example of the method of manufacturing a denture according to the first embodiment, after providing information on the wearer to the information providing region of the base floor, a light-transmitting plate-shaped resin sheet for floor molding is further provided. The cover floor is characterized by including a step of superposing on a plate-shaped resin resin for floor molding that serves as a foundation floor.

  As shown in FIG. 10, since the modified example of the manufacturing method of the denture based on this Embodiment 1 is the same from step S10 to step S50 shown in FIG. 1 from step S210 to step S250, it demonstrates. Is omitted.

When the dental technician performs an information providing step (step S250) of printing information about the wearer as the print information W by the printing device in the information providing region S of the floor molding resin plate P, the cover placement step is performed. I do.
In the cover placement step, as shown in FIG. 11, the light-transmitting plate-shaped floor molding resin plate Pc is used as a cover floor and is superposed on the plate-shaped floor molding resin plate P serving as a base floor (step S260). The floor molding resin plate Pc may be the same resin plate as the floor molding resin plate P. Since the floor molding resin plate Pc and the floor molding resin plate P are overlapped to form a single resin plate, the thickness of the floor molding resin plate Pc and the floor molding resin plate P is the floor shown in FIG. It is desirable that the thickness is smaller than that of the molding resin plate P and that the number of the two sheets is the same as that of the floor molding resin plate P shown in FIG.

Then, the dental technician performs a transfer process. In the transfer step, as shown in FIG. 12, the floor molding resin plate P and the floor molding resin plate P are heated, and the floor molding resin plate P softened by heating disposed on the impression model M and the floor molding. The shape of the impression model M is transferred while the floor molding resin plate P and the floor molding resin plate P are integrated into one sheet by applying pressure and heating on the resin plate P (step S270).
When the transfer process is completed, the subsequent processes from step S280 to step S320 are the same as the processes from step S70 to step S110 shown in FIG.

  In the denture 30x obtained in this way shown in FIG. 13, the printing information W is printed on the foundation floor 21 formed from the floor-forming resin plate P (see FIG. 11). A cover floor 21c formed from the molding resin plate Pc (see FIG. 11) is overlapped to form a denture base 25x. Therefore, since the cover floor 21c protects the printing information W of the foundation floor 21 and covers the unevenness of the printing information W, the printing information W can be prevented from fading or scraping, and the wearer can remove the complete denture 30x. It can be installed in the same way as a conventional complete denture.

(Embodiment 2)
A method for manufacturing a plate denture according to Embodiment 2 of the present invention will be described with reference to the drawings.
The method for manufacturing a bedded denture according to the second embodiment is characterized in that the information providing area of the foundation floor is an area where the occlusal levee is provided, and the gingiva portion is formed of a light-transmitting molded member. .

When the base floor 21 shown in FIG. 14 prints the printing information W on the floor molding resin plate P in step S50 shown in FIG. The print information W is given and the shape of the impression model M is transferred.
And in step S110 shown in FIG. 1, when forming a gingival part with the resin for floors in this foundation floor 21, by using the floor resin which has a light transmittance, as shown in FIG. 23 protects the printing information W of the foundation floor 21 and covers the unevenness of the printing information W, so that the printing information W can be prevented from fading or scraping, and the wearer can replace the complete denture 30y with the conventional complete denture. Can be installed without any change.

(Embodiment 3)
A method for manufacturing a plate denture according to Embodiment 3 of the present invention will be described with reference to the drawings.
The method for manufacturing a denture according to Embodiment 3 is characterized in that after the foundation floor is molded, information on the wearer is given to the foundation floor.
