Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plate denture, a method for assigning a name to the plate denture, and a type for assigning the name, and in particular, the owner of the plate denture by a familiar manual operation using a common machine tool that is regularly provided in a dental laboratory. It is devised so that a name can be given.
[0002]
[Prior art]
In general, a denture is produced by a reciprocal collaboration between a dental clinic and a laboratory, but the owner's name is not given to it. For example, it is misplaced in a nursing home or from a laboratory. When a delivery error to a dental clinic occurs, the owner of the denture cannot be quickly identified and identified, and not only for the daily life of the owner, but also for the necessary manufacturing work at the dental clinic or technical laboratory. It ’s inconvenient.
[0003]
In this respect, for the purpose of helping to identify the identity of an elderly person who has become unconscious or who died accidentally, as a known technique to give various identification information such as the name, blood type, telephone number, address, etc. of the elderly person to the denture base, Utility model registration No. 3080133 and Japanese Patent Laid-Open No. 7-124180 have been proposed, and these are in common with the present invention in that they include the purpose of giving a name to the denture base.
[0004]
[Problems to be solved by the invention]
However, the former known device is intended to embed an information description piece (2) in a so-called retrofitting type in the denture base (1A) for a ready-made complete denture (1), and the information description piece (2). Is made of a film (2B) or a metal plate (2D) made of a material different from that of the denture base (1A), so it has poor affinity and maintains a durable fixing strength even when covered with a temporary transparent resin (1D). I can't.
[0005]
Also, even when creating the information description piece (2), the information (2A) such as characters, symbols and photographs is printed on the film (2B) by using a personal computer, and then the film (2B) is enlarged or It is necessary to reduce and further laminate (2C), or to engrave or place information (2A1) on the metal plate (2D) instead of the film (2B).
[0006]
These operations are completely different from the dental technician work that is usually performed, and are very troublesome, and it is difficult to produce the information description piece (2) at a low cost. Special PCs, laminators, and engraving machines that are used only for granting must also be procured.
[0007]
Further, if the film (2B) on which the information (2A) is printed is reduced, it becomes difficult for the owner (the elderly) of the denture (1) to read the information (2A) with the naked eye. Even if 2B) is reduced, the information description piece (2) created from now on has a size including a blank portion of the film (2B), and has a size as shown in FIG. 6 in the denture base (1A). Because it is designed to be embedded in the space, there is a limit to downsizing itself.
[0008]
The whole of the embedded information describing piece (2) is also observed through the transparent resin (1D), and information is obtained from the denture base (1A) when the denture (1) is used in the oral cavity. It is inevitable that the description piece (2) is unsightly exposed and inhibits the appearance cosmetic effect of the denture (1).
[0009]
In addition, in the information description piece (2) in which the information (2A1) is engraved or placed on the metal plate (2D), the embedded denture (1) is gradually increased in weight, and thus it is difficult to use it. There is also a problem that gives a sense of discomfort.
[0010]
On the other hand, the latter known invention is also a method for printing on a ready-made completed denture, and irradiating the denture base with a laser afterwards, which is also used only for marking and barcode printing. YAG lasers, carbon dioxide lasers, semiconductor lasers, and the like, and advanced operations different from the usual dental technician work are required.
[0011]
In any case, in the case of the above-mentioned known technology, in the daily life at a nursing home or in the collaborative production work between the dental clinic and the technical laboratory, the necessity of identifying and identifying the owner of the denture with the naked eye, It is not considered.
[0012]
[Means for Solving the Problems]
The present invention contemplates a drastic solution to such a problem. First, as a configuration of a bed denture, a convex drawing portion formed from one letter of Katakana, Hiragana or alphabet and a body portion excluding this are provided . A plurality of name-giving letters that are molded in advance from an acrylic resin, sulfone resin, or other suitable thermoplastic resin of the same material that differs only in the color of the denture resin floor,
[0013]
To the part that becomes difficult to see when mounted on the resin floor, the convex part is directly embedded and integrated as a side-by-side part, and then the body part protruding from the resin floor is removed,
[0014]
It is characterized in that the name of the owner that can be read with the naked eye is given by a plurality of convex drawing parts to be displayed in combination from the resin floor ,
[0015]
In addition, as a method for assigning a name to a denture, a plurality of name-giving type letters that are to be combined are pre-molded from an acrylic resin of the same material that differs only in color from the resin floor of the denture. Prepare,
[0016]
First, partially heat-soften the paraffin wax bed of the wax denture, and embed and fix the convex print portion of the above type in a parallel installation state in that part,
[0017]
After that, the body part of the above-mentioned type that protrudes and remains from the resin bed replaced with the paraffin wax bed by passing through the wax denture burying process, the flow wax process and the heating resin polymerization process, Remove it by grinding,
[0018]
The first feature is that only the convex part of the above-mentioned type is exposed from the denture resin floor,
[0019]
Similarly, a plurality of name-giving type letters that will be presented in combination are pre-molded from acrylic resin or sulfone resin of the same material that differs only in the colored color from the resin floor of the denture,
[0020]
First of all, a recessed groove embedded in the type is partially drilled in the resin floor of the finished denture, and the immediate polymerization resin at normal temperature is filled in the interior, and at the same time, the convex part of the above type is embedded and fixed in a parallel installed state. ,
[0021]
The body part of the type that will stick out and remain from the resin floor, after the immediate polymerization resin is cooled and cured, is removed by grinding,
[0022]
A second feature is that only the convex portion of the type is exposed from the resin floor of the denture.
[0023]
In addition, as a type for assigning a name to the above-mentioned denture, the embedding depth restriction plate on the resin floor due to its structure, and a katakana, hiragana or one letter of the alphabet which protrudes a certain height in the rearward direction, the embedding depth is also the same The resin floor is colored with a handle that protrudes forward from the regulation plate by a certain height that is taller than the single character, and a designated mark piece of character direction that projects laterally from the base of the handle by a certain length. It is integrally molded from the same material acrylic resin, sulfone resin, and other suitable thermoplastic resins that differ only in color,
[0024]
While embedding the above-mentioned single letter as a convex drawing part in the resin floor of a denture with dentures, the remaining embedding depth regulating plate, handle, and designated mark piece are also projected from the resin floor and polished as a body part. It is characterized in that it is determined to be deleted by processing.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the details of the present invention will be described with reference to the drawings. FIGS. 1 to 4 show a type letter (P) for giving a name to a denture (A) according to the present invention, which is a denture (A). The acrylic resin, sulfone resin, and other suitable thermoplastic resins of the same material that can maintain the affinity with the resin floor (10) while having a colored color such as white and blue different from the resin floor (10) of It is integrally formed in such a form.
[0026]
That is, (11) is an embedding depth regulating plate for the type (P) with respect to the denture (A), and has a constant thickness (for example, about 0.5 mm to 1.0 mm) and a size (for example, about 4 mm × 4 mm), and the two parallel sides of the quadrangle are useful for orderly embedding a plurality of printed characters (P) in a parallel state.
[0027]
(12) is a convex character portion protruding rearward from the central portion of the embedded depth regulating plate (11) by a certain height (H1) (for example, about 1.5 mm to 2.0 mm). Formed from a single letter of the alphabet. In addition, when viewed from the rear, the single character presents left and right reverse images, and can be read as a normal image only when viewed from the front when embedded in the denture (A).
[0028]
On the other hand, (13) is a handle that protrudes forward from the center of the embedding depth regulating plate (11) by a certain height (H2) (for example, about 4 mm to 5 mm) that is taller than the above-mentioned convex image portion (12). The diameter of the base part is a slightly tapered column shape of about 2 mm, for example.
[0029]
Grab the handle (13) directly with the fingertip of the operator's finger or using an appropriate tool such as tweezers, and embed only the convex part (12) of the type (P) into the denture (A). It is like that.
[0030]
In addition, from the base of the handle (13), the designated mark piece (14) of the character directionality in the convex image portion (12) is horizontally oriented by a certain length (L) (for example, about 1.0 mm to 1.5 mm). The character directionality of the above-mentioned convex image portion (12) that is not seen from the front when the type (P) is embedded in the denture (A) is known from the rear by the designated mark piece (14). It is possible to embed a plurality of printed characters (P) as an accurate directional parallel state.
[0031]
In that case, the embedding depth regulating plate (11) is stably locked to the surface of the denture (A) as a stopper for regulating the embedding depth of the convex image portion (12) to be constant. The embedded depth restricting plate (11), the handle (13), and the designated mark piece (14) serve as the body part (B) excluding the convex part (12) of the type (P), and the denture (A) Therefore, it is removed after receiving a final polishing process.
[0032]
As such a name-giving letter (P), it can be integrally formed into a so-called rose-shaped single article having one letter of its convex character part (12), but it is convenient for preventing loss and embedding. 5-7, as is apparent from FIGS. 5-7, the same letter of the katakana, hiragana, or alphabet that forms the convex drawing portion (12) is the type character that protrudes from the embedding depth regulating plate (11) ( It is preferable to form a plurality of P) in a pivotally connected state in which the restriction plate (11) can be broken and divided only between adjacent ones of the restriction plate (11). Since the embedded depth regulating plates (11) are adjacent to each other in a thin state with a V-groove (15), the operator can easily fold and divide them.
[0033]
In any case, the name-giving type letter (P) prepared as the above-mentioned structure is embedded and integrated in a plurality of parallel states in the denture (A), and forms a convex character part (12). The name (N) of the owner is expressed by each combination.
[0034]
However, if the number of combined characters is too large, the name (N) becomes unsightly and easily exposed in the state where the denture (A) is worn and used in the oral cavity. On the other hand, if the size of each character is small and fine, However, even if it is necessary to increase the number of characters of the owner as the name (N), one letter of the alphabet that will be the initial of the first name ( It is desirable to keep it to the extent that it is attached to the rear side.
[0035]
In the present invention, by using the above-mentioned type (P), the name (N) of the owner can be given from the beginning of the production of the denture (A), and the finished denture (A) that has already been completed. It is also possible to give a name (N) as a subsequent repair.
[0036]
That is, FIGS. 8 to 19 show the production process of the plate denture (A), and in giving the owner's name (N) from the beginning of the denture of the wax denture (W) for which the trial fit has been completed. The paraffin wax bed (gingiva) (16) is first partially heated and softened. The softened part is determined so as not to be unsightly exposed as a part that becomes difficult to see when the completed denture (A) is used in the oral cavity. (17) is an artificial tooth, and (18) is a gypsum base.
[0037]
On the other hand, a plurality of type characters (P) used in combination as the target name (N) are selected, and the softened portion of the wax bed (16) is spread over the convex portion (12) of the type (P). , 9 is embedded in a parallel installation state.
[0038]
At the time of the work, the grip (13) of each character (P) is grasped, and the directionality of the letter image portion (12) is aligned regularly by visual inspection of the designated mark piece (14), and the embedding depth regulating plate (11) is arranged. By fixing the wax floor (16) to the surface, the embedding depth of the convex image portion (12) is fixed so as to be in a uniform state as a whole.
[0039]
In the unlikely event that the embedding depth regulating plate (11) of the type (P) is not in close contact with the wax bed (16) of the wax denture (W) and there is a mutual gap, mud gypsum in the subsequent process (Investment) goes around and can't get a beautiful finish. Check carefully.
[0040]
When the softened part of the wax bed (16) is hardened and the type (P) is fixed and integrated, the wax denture (W) is then buried as a lower flask (19) as shown in FIG. ) In the middle part of the inner wall, and is first buried in the mud gypsum (20). At that time, it goes without saying that the edge of the wax bed (16) is positioned on the parting line (OO) between the lower flask (19) and the upper flask (21).
[0041]
When the mud gypsum (20) subjected to primary burial has hardened, the wax denture (W) is continuously put into the mud gypsum (22) of the upper flask (21) as shown in FIG. The flasks are buried and both flasks (19) and (21) are kept in a mold-clamping state, and then left to stand until the secondary buried mud gypsum (22) is cured.
[0042]
In the subsequent wax process, if both wax flasks (19) and (21) are heated and then opened to melt the wax bed (16) of the wax denture (W), the resin is replaced later. A floor forming space (cavity) (C) is created.
[0043]
In this state, as is apparent from FIGS. 12 and 13, the artificial tooth (17) is embedded and integrated in the hardened gypsum (22) in the upper flask (21), while the convexity of the name-giving type (P) is Only the stroke part (12) protrudes into the molding space (C) for the resin floor, and the body part (B) where the letter (P) remains is embedded and fixed in the plaster (22) like the artificial tooth (17). Result.
[0044]
Then, as a heating resin polymerization step, as shown in FIG. 14, the bowl-shaped resin (R) is pressure-filled into the molding space (C) for the resin bed as shown in FIG. ) (21) is heated to polymerize the resin (R). A spool for filling the bowl-shaped resin (R) is not shown.
[0045]
When the denture base resin (R) is hardened, both flasks (19) and (21) are opened to decompose the hardened gypsum (20) and (22) for primary and secondary embedding. Thus, it can be taken out as a molded denture (A) formed from the resin floor (10).
[0046]
The resin bed (10) of the denture (A) is embedded with the convex portion (12) of the type (P) as is apparent from FIGS. 15 and 16, but the type (P) remains. Since the body part (B) is still overhanging from the resin floor (10), as a final step, the body part (B) of the type (P) is crushed and polished, so that the embedding depth regulating plate (11) And the handle (13) and the designated mark piece (14) are deleted, and the convex portion (12) of the printed character (P) and the resin floor (10) are finished in a smooth state.
[0047]
Then, as shown in FIGS. 17 to 19, the letter image portion (12) of the type (P) is displayed as a normal image from the resin floor (10) of the denture (A), and from the plurality of combinations. The intended name (N) can be read with the naked eye, which is also due to the fact that the type (P) has a different colored color from the resin floor (10).
[0048]
In this respect, in the embodiments of FIGS. 8 to 19, the complete denture for the lower jaw is shown, but the denture for the upper jaw and the partial denture are also passed through the same process as described above, so A name (N) can be given, and the name (N) giving position can also be set on the inner surface of the resin floor (10) as shown in FIG.
[0049]
In any case, since the name-giving type (P) is prepared by molding from a thermoplastic resin of the same material as the resin bed (10) of the denture (A), this is used for the resin bed (10). At the same time as the heat polymerization, it can be embedded and integrated firmly, and a denture with denture (A) with excellent durability (A) can be obtained.
[0050]
Further, FIGS. 21 to 29 show a process of assigning the name (N) to the ready-made denture (A), and the owner's name (N) is assigned to the resin floor (10) of the completed denture (A). In some cases, the embedded grooves (23) having a size and depth substantially corresponding to a plurality of types (P) used in combination are first formed into the resin floor (10), and then the elongated rectangular shape as shown in FIG. Drill into.
[0051]
As in the embodiment of FIGS. 8 to 19, the drilled site of the resin floor (10) is positioned as a site that is unsightly and unexposed in a state where the denture (A) is mounted and used in the oral cavity.
[0052]
Next, the type-embedded concave groove (23) is filled with an immediate polymerization resin (24) at room temperature, and immediately after that, a plurality of types (P) are embedded in a parallel installation state as shown in FIGS.
[0053]
At that time, it is possible to embed a plurality of type letters (P) separately in a separate state, but if the number of characters of the target name (N) is large, the work is cumbersome and neatly arranged. Therefore, it is preferable to prepare one type support rod (25) common to a plurality of types (P) as shown in FIGS. 21 to 23 in advance from a stick wax having adhesive strength. In addition, a type (P) handle (13) is planted on the support rod (25) and inserted into the embedded concave groove (23) at the same time. Immediately thereafter, an immediate polymerization resin (24) at normal temperature is filled. To do.
[0054]
In any case, only the convex part (12) of the type (P) is embedded and fixed in the resin floor (10), and the body part excluding the convex part (12) of the type (P) ( B) protrudes from the surface of the resin floor (10). Therefore, if the type (P) is fixed and integrated by curing the room temperature polymerization resin (24), the body part (B) of the type (P) As shown in FIGS. 28 and 29, the embedding depth restricting plate (11), the designated mark piece (14), and the handle (13) of the convex portion (12) are deleted. Of course, the type support bar (25) is also removed from the resin floor (10).
[0055]
The denture denture (A) to which the owner's name (N) is assigned in this way is in a finished state substantially the same as that to which the name (N) is assigned from the beginning of production in FIGS. The name-giving letter (P) is made of a thermoplastic resin of the same material as the resin bed (10) of the denture (A), and not only has excellent embedding strength and appearance cosmetic effect, but also the resin bed (10) The name (N) expressed from the convex part (12) of the type (P) can be clearly read with the naked eye by using different colored colors.
[0056]
【The invention's effect】
As described above, in the denture of denture (A) of the present invention, the convex part (12) formed from katakana, hiragana or one letter of the alphabet and the body part (B) excluding this are part of the denture (A). A plurality of name-giving letters (P) formed in advance from an acrylic resin, sulfone resin, or other suitable thermoplastic resin of the same material that differs only in color from the resin floor (10),
[0057]
The convex part (12) is directly embedded and integrated as a side- by-side state into a part of the resin floor (10) that is difficult to see when mounted and used , and the resin floor (10) extends and remains from the resin floor (10). Delete the body part (B)
[0058]
Since the name (N) of the owner that can be read with the naked eye is given by a plurality of convex character portions (12) to be combined and expressed from the resin floor (10) , the prior art described at the beginning Even if there is a misplacement in a nursing home or a delivery error from the laboratory to the dental clinic, the owner of the denture (A) is identified and identified from the name (N) with the naked eye. This is extremely convenient not only for the daily life of the elderly, but also for the production of the plate denture (A) by the collaborative work between the dental clinic and the laboratory.
[0059]
Further, the type (P) for giving the name (N) and the resin bed (10) of the denture (A) are made of the same material as a thermoplastic resin such as acrylic resin or sulfone resin. The durable embedding strength of P) and an elegant appearance makeup can be obtained, and the name (N) can be clearly read by the colored color of the type (P) different from the resin floor (10).
[0060]
And according to the naming method of Claim 2, a resin bed (from the beginning of manufacture of a denture (A) using the usual method which is familiar with the common machinery appliances which are always equipped with in a dental laboratory. 10) The effect of being able to embed and integrate the name-giving type (P) at the same time as the heat polymerization and finish the owner's name (N) in an elegant state after the final polishing process in the usual manner And is highly practical.
[0061]
On the other hand, according to the method for assigning a name according to claim 3, it is possible to retrofit the resin floor (10) to the resin floor (10) by using the technique already used in a technical laboratory, even for a ready-made complete denture (A). The owner's name (N) can be easily assigned, and it does not require a special personal computer, laminator, laser, or the like as in the prior art, and is remarkably useful for cost reduction in processing.
[0062]
In that case, if the name assigning method according to claim 4 is adopted, a plurality of name assigning letters (P) are more and more conveniently and entirely arranged on the denture (A) resin floor (10). It can be embedded as a parallel state, which helps to improve the workability.
[0063]
Further, in the configuration of the name-giving type character (P) according to claim 5, the handle (13) is grasped directly or by using an appropriate tool, and the character directionality of the convex character portion (12) is designated. By aligning the mark piece (14) in an orderly manner and maintaining the embedding depth of the convex portion (12) at a constant level on the restriction plate (11), the denture base (A) resin bed ( 10) can be embedded very easily and has excellent workability.
[0064]
In particular, if the configuration of claim 6 is adopted, the type (P) can be rationally produced according to the frequency of the selected and used characters, and the embedded depth regulating plate (11) can be adjacent. There is also an effect that can be used conveniently and conveniently by breaking and dividing the mating parts.
