When a patient visits a dentist's office, he or she is generally asked what kind of artificial tooth he or she wants to have. However, most of them ask questions about whether or not insurance is applied (including material types). For example, even if a patient wants an artificial tooth with a novel design as a fashion tool, the dentist usually rarely asks if there is such a desire. In addition, it is difficult for patients to convey such hopes to the dentist, and even if they do, they may be refused by the dentist. In recent years, although techniques for easily and efficiently modeling dental prostheses such as artificial teeth have been developed (see, for example, Patent Document 1), at present, patients themselves can freely select the design of dental prostheses. There is no environment where you can create or create.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing a model of a dental prosthesis providing business according to an embodiment of the present invention. In this embodiment, a dental prosthesis providing business is carried out by EC (Electronic Commerce). The dental prosthesis providing business handles dental prostheses such as artificial teeth. An artificial tooth is an artificial tooth made to restore the function of a lost natural tooth. Artificial teeth include, for example, crowns and bridges. Dental prostheses also include inlays, dentures and the like.

In the past, even if a patient wanted an artificial tooth with a novel design as a fashion tool, it was difficult to convey such a desire to the dentist, and even if he did, the dentist would refuse it. In addition, since artificial teeth with high aesthetics are often not covered by insurance, the amount borne by the patient tends to be high. Furthermore, since such artificial teeth are free medical treatment, the cost of treatment varies depending on the dentist. Patients could not compare the cost of treatment with other dentists, and sometimes chose treatment that was not covered by insurance, with anxiety about the cost.

In addition to the above, in the past, dental technicians made artificial teeth at the request of dentists, so it was difficult for patients to reach the dental technicians, and patients had less freedom to choose artificial tooth designs. rice field. In addition, the dental technician paints the artificial tooth with a natural color by painting it with a brush. With this method, it was difficult to produce artificial teeth designed with pictures and characters desired by patients as fashion tools. Furthermore, as a personal information management tool, it was extremely difficult to produce an artificial tooth designed with a two-dimensional bar code representing personal information and a will.

In the dental prosthesis providing business of the present embodiment, the patient selects and creates the design of the dental prosthesis. This business deals with self-financed dental prostheses and clearly shows their prices to patients. Therefore, the patient can order the dental prosthesis and receive treatment with peace of mind as if he / she were shopping normally. In addition, by selling dental prostheses at reasonable prices, it is expected that artificial teeth such as ceramics will become widespread. This spread will improve the self-sufficiency rate and contribute to the increase in sales of dental clinics. Further, in the dental prosthesis providing business of the present embodiment, the coloring of the dental prosthesis is digitized. This makes it possible to express colors with high accuracy and to output pictures and characters desired by the patient on the surface. Therefore, for example, the artificial tooth can be used as a fashion tool. Furthermore, it becomes possible to output information such as a two-dimensional bar code to an artificial tooth or the like, and a dental prosthesis can be used as a personal information management tool. In this way, the dental prosthesis providing business of the present embodiment brings about the realization of the dental prosthesis desired by the patient, the safe treatment of the dental prosthesis at its own expense, and the provision of new value of the dental prosthesis. Is done.

Patients who purchase a dental prosthesis of the desired design using the dental prosthesis providing business of the present embodiment will be more concerned about teeth throughout the year. This may lead to the maintenance / improvement of oral health and, by extension, the maintenance / improvement of general health. The dental prosthesis providing business of the present embodiment also aims to attract good dentists to patients who have invested to make their smiles nice.

The dental prosthesis provider shown in FIG. 1 provides dental prostheses by EC. The dental prosthesis provider promotes the dental prosthesis to the patient. In the promotion, in addition to presenting the selection or design of the dental prosthesis that can be created and the price of the dental prosthesis of the design, the dental treatment that the patient wears the dental prosthesis of the design selected or created is performed. Including the introduction of the clinic. When introducing a dental clinic, the standard treatment fee is also presented. The patient goes to the dental clinic to receive treatment and examination to wear the dental prosthesis, while ordering the dental prosthesis of the desired design from the EC site and paying the purchase cost to the dental prosthesis provider. pay. The dental office sends intraoral data showing the three-dimensional shape of the patient's oral cavity to the dental prosthesis provider. The dental prosthesis provider combines the intraoral data with the design of the dental prosthesis ordered by the patient to create the modeling data of the dental prosthesis. The dental prosthesis provider creates a dental prosthesis using a three-dimensional modeling device such as a 3D (three-dimensional) printer using the created modeling data, and delivers it to the dental clinic. The dental clinic provides treatment for the patient to wear the dental prosthesis shaped by the dental prosthesis provider. The patient pays for the treatment excluding the unit price of the dental prosthesis. When the dental prosthesis is a denture, the design of the dental prosthesis is the design of the artificial tooth part used for the denture, and the dental prosthesis delivered to the dental clinic is a 3D printer or the like. It is a denture manufactured using an artificial tooth modeled by the three-dimensional modeling device of. The same applies to the following.

Only dental clinics that have entered into a franchise agreement with a dental prosthesis provider handle dental prostheses, which are products of the dental prosthesis providers. The franchise-contracted dental clinic sets the cost of treatment for wearing a dental prosthesis based on the standard treatment cost agreed with the dental prosthesis provider. Dental clinics can receive promotional support to improve their own expense ratio as a consideration for franchising. In addition, in the early stages of the EC business, dental clinics can also receive referral fees from dental prosthesis providers by referrals to new patients. After the number of users of dental prosthesis providers increases, dental clinics can be matched with new patients by dental prosthesis providers.

Examples of usage scenes of the dental prosthesis providing business include the following. The first example is when a patient for the purpose of treatment receives medical treatment at his / her dental clinic. When it is determined that a dental prosthesis such as a tooth insert is needed, the patient is referred by a dentist to a dental prosthesis provider and purchases a dental prosthesis with the desired design from the dental prosthesis provider. do. On the other hand, the dental prosthesis provider receives the patient's oral data from the dental clinic and models the dental prosthesis with the patient's desired design by a 3D printer. The dental prosthesis is sent to the dentist and placed in the patient's oral cavity.

Another example is for a fashion patient who has a concrete design of what kind of dental prosthesis he wants to put in. The patient wants to purchase a dental prosthesis with the desired design from a dental prosthesis provider, and after the purchase, put the dental prosthesis in a dental clinic selected from the dental clinics introduced on the EC site. inform. The dental office photographs the patient's oral data and sends it to the dental prosthesis provider, who then sculpts the dental prosthesis with the design of the patient's choice with a 3D printer. The shaped dental prosthesis is sent to the dentist and placed in the patient's oral cavity.

The dental prosthesis providing business of this embodiment brings manufacturing innovation, technological innovation, and industry reform to dentistry, and can create a new world of dentistry. The manufacturing innovation of dental prostheses using 3D printers makes it possible to form dental prostheses in large quantities faster than before. As the productivity of dental prostheses increases, it is possible to win orders from many customers and to lock in dental laboratories. In addition, the technological innovation of coloring dental prostheses using 3D printers will streamline dental technician work and promote a break from the labor-intensive industry. In addition, EMPOWERING DIGITAL WORKPLACES will be realized by combining a scanner with the coloring of dental prostheses using a 3D printer and performing all-digitalization, further improving the efficiency of dental technicians and increasing the commercial distribution of dentistry. It will bring about changing industry reforms.

In such a new world of dentistry, artificial teeth such as ceramic teeth will become widespread at affordable prices. In addition, new value will be created in dentistry, such as artificial teeth becoming fashion tools and artificial teeth becoming sensor devices. For example, an artificial tooth can be a fashion tool as well as a nail because an illustration of a design desired by a patient can be inserted into the artificial tooth. With the replaceable provisional teeth, it is possible to wear fashionable artificial teeth only at events such as Halloween and theme parks, and return them to normal artificial teeth the next day. Also, if the zirconia teeth are not supposed to be replaced, for example, you can paint a picture on the artificial teeth of the double teeth so that you can see a little when you laugh.

Further, by printing a two-dimensional bar code or the like on the dental prosthesis, the dental prosthesis can be used as a sensor device incorporating personal information of the patient or the like. If it is black printing, it is possible to print on the surface corresponding to the back side of the tooth and print on the surface corresponding to the front side of the tooth so as not to give a strange appearance. The code printed on the front side can also be used as authentication information in an ATM (Automatic Teller Machine) or the like. Furthermore, it is possible to use the code printed on the dental prosthesis instead of an identification card such as a passport. On the other hand, by incorporating some kind of message into the two-dimensional bar code, it is possible to leave it as a will, for example, to relatives. The data collected by the dental prosthesis provider can also be used to build a cure system that utilizes the patient's big data.

FIG. 2 is a correlation diagram of players related to the dental prosthesis providing business of the present embodiment.
The dental office has a franchise agreement with a dental prosthesis provider. The dental prosthesis provider may have a dental laboratory and a 3D modeling center, or may partner with an external dental laboratory and 3D modeling center. Further, the dental laboratory may also serve as a 3D modeling center. The dental prosthesis provider retains the clinic information of the dental clinic registered as a franchise on the EC site.

The dental office accepts patients who have come to the clinic and obtains the impression of the abutment tooth and the surrounding teeth for prosthesis of the dental prosthesis. For example, a dentist photographs the patient's oral cavity with an oral scanner and uploads the obtained oral data to the cloud. Alternatively, the dentist creates an impression model of the patient's oral cavity using the impression kit and ships it to the dental laboratory.

The patient is referred to the EC site by the treated dentist and registers customer information. The patient selects or creates the desired design for the dental prosthesis on the EC site. The patient sends the desired data indicating the desired design to the EC site to place an order for the dental prosthesis. When a dental prosthesis provider receives an order for a dental prosthesis ordered from an EC site, it outsources scanning correction to a dental laboratory and 3D modeling of the dental prosthesis to a 3D modeling center.

The dental laboratory downloads the intraoral data uploaded by the dental clinic to the cloud. Alternatively, the dental laboratory accepts the impression model sent by the dental clinic and scans it with a 3D scanner to obtain intraoral data. The dental laboratory uses a personal computer (PC) equipped with CAD (computer-aided design) software as a scanning correction device to correct intraoral data. The dental laboratory uploads the oral improvement data generated by the correction.

The 3D modeling center downloads the oral improvement data uploaded by the dental laboratory and the desired data uploaded by the dental prosthesis provider or the dental laboratory. The 3D modeling center uses the desired data and the oral improvement data to generate modeling data for the dental prosthesis (the part of the artificial tooth if the dental prosthesis is a denture). The 3D printer models a dental prosthesis based on the modeling data. The modeled dental prosthesis is shipped to the dentist's office. The dental office treats the patient with a dental prosthesis.

The patient may access the EC site, register customer information, and place an order for a dental prosthesis before visiting the dental clinic. The EC site uses clinic information to match new customers with franchise dental clinics and mediate them. Patients go to the dental clinic referred by matching for treatment.

The processing unit 305 of the dental terminal 30 writes the order notification in the storage unit 304 and displays it on the display unit 303.

If the dental clinic does not have the intraoral scanner 35, the intraoral data correction request transmitted from the management device 10 does not include the intraoral data. The dental laboratory attaches a label printed with the dental clinic ID, patient ID, medical treatment date, order number, treatment target, prosthesis type, etc. to the patient's impression model obtained at the time of the examination. Send to the place. This impression model is a tooth profile model of the patient's abutment tooth and its surrounding teeth. At the dental laboratory, an impression model is taken with a 3D scanner 55 and intraoral data is generated. The processing unit 505 of the scanning correction device 50 receives the intraoral data from the 3D scanner 55. The processing unit 505 writes the oral data in the storage unit 504 in association with the oral data correction request specified by the dental clinic ID, the patient ID, the medical treatment date, and the order number input by the input unit 501.

In FIG. 16, the correction unit 506 of the scanning correction device 50 displays the three-dimensional shape, color, texture information, treatment target, prosthesis type, etc. indicated by the intraoral data on the display unit 503. The correction unit 506 corrects the intraoral data according to the information and instructions input by the dental technician by the input unit 501, and generates the intraoral improvement data (step S405). The correction target is one or both of the three-dimensional shape and the color indicated by the oral improvement data. As for the color, the color on the surface of the dental prosthesis and the color on the inside can be corrected. The intraoral scanner 35 may not be able to measure detailed color information. In addition, natural teeth usually have different inner and outer colors. Therefore, the dental technician determines the surface color and the inside of the dental prosthesis based on the texture information given to the oral data and the color of the abutment tooth and the surrounding teeth indicated by the oral data. Select a color for. Intraoral data is often point cloud data and may be converted to STL data for correction. If the shape collapses due to this conversion, the collapse is corrected.

The correction unit 506 may generate the oral improvement data in which the oral data is corrected by using the correction model learned by AI. For example, the correction model inputs information on the three-dimensional shape, color, and texture indicated by the intraoral data, and outputs the intraoral improvement data. Such a correction model is learned by using a set of the oral data before correction and the oral improvement data which is the corrected oral data created by manually correcting the oral data. To. A correction model may be learned for each type of prosthesis. The correction unit 506 inputs the intraoral data into the correction model according to the type of the prosthesis, and obtains the intraoral improvement data as an output. Further, the correction model may be a model in which the oral data before correction and the elapsed time from the day when the oral data is photographed are input, and the oral improvement data is output. This also allows the patient to place an order to replace a previously worn dental prosthesis with a new dental prosthesis. The correction model is provided, for example, by a dental prosthesis provider. The correction unit 506 may generate the oral improvement data corrected by the AI according to the information and instructions input by the dental technician by the input unit 501.

(Manufacturing method of medical devices)
A method for manufacturing a medical device according to a related technique includes a layer forming step of applying a modeling liquid containing zirconia particles to a predetermined region to form a zirconia layer, and metal ions or metal ions using an inkjet head in the predetermined region of the zirconia layer. The molded product obtained by repeating the coloring liquid applying step of applying the coloring liquid containing a metal complex and the layer forming step and the coloring liquid applying step a plurality of times is fired in a high temperature environment. It includes a reaction step of reacting the zirconia contained in the zirconia layer with the metal ion or the metal complex, and further includes other steps as necessary.

Conventional three-dimensional (3D) printers such as additive manufacturing use, for example, a stereolithography (SLA) method using ultraviolet rays. However, with the conventional method using ultraviolet rays, it is necessary for the dental technician to build up the color reproduction after modeling, which is a great advantage over the conventional CAD / CAM zirconia disc with gradation. There is a problem that it is hard to say.
In addition, if a dental technician builds up after modeling to reproduce the conventional color, if the model is scraped to adjust the meshing of the teeth, the color applied to the surface will come off. There is a problem that the white color of zirconia is exposed.
Further, in the conventional liquid obtained by ionizing or complexing a metal species, a dental prosthesis cut into a desired shape by CAD / CAM or the like is manually painted with a brush or the like to color the dental prosthesis. There is a problem that stable coloring cannot be achieved due to the large difference between people.

Therefore, in the related technology, by modeling using a liquid set having a liquid for modeling containing zirconia particles and a liquid for coloring that specifically develops color with respect to zirconia, the liquid for coloring is molded at the time of laminated molding. Since it can be applied to the inside, it is possible to color the inside of the modeled object even if the modeled object is scraped, unlike the case where only the surface is colored, so the excellent effect that the white color of zirconia is not exposed is excellent. can get.
The modeling liquid contains a small amount of binder to maintain its shape after forming a zirconia layer and volatilizing the solvent. However, it should be noted that if the amount of the binder added increases, the viscosity of the modeling liquid increases and ejection failure occurs. On the other hand, the coloring liquid needs to be ejected from an inkjet head different from the modeling liquid. This is because the material to be doped in the lattice defects of zirconia is dispersed in the coloring liquid, and if this is contained in the modeling liquid, the dispersion stability is lost, and the zirconia particles and coloring are lost. The agent begins to aggregate, making it difficult to eject from the inkjet head.
Therefore, according to the method for manufacturing a medical device of the related technology, it is possible to manufacture a medical device using zirconia easily and efficiently, while coloring with high strength and dimensional accuracy.

Hereinafter, the liquid set used in the method for manufacturing a medical device in the related technology will be described in detail.

(Liquid set)
The liquid set includes a modeling liquid containing zirconia particles, a coloring liquid that specifically develops a color with respect to zirconia, and, if necessary, other materials.

<Coloring liquid>
The coloring liquid is not particularly limited as long as it has the property of developing the color of the zirconia particles, and can be appropriately selected depending on the intended purpose. Specifically, a coloring solution in which metals and / or metal ions are stabilized by a complexing agent and dissolved in an aqueous medium containing various components can be used as a coloring liquid. Further, in order to reproduce the color of natural teeth, it is preferable to use a coloring liquid consisting of at least four kinds of colors.

As the complexing agent, a pure organic substance containing only elements such as H, N, O, and C is preferable, and a substance that can be completely burned without leaving a harmful residue during firing is preferable.

The colorant contained in the coloring liquid includes a mixture of different metals and / or metal ions having different atoms or ionic radii, and these metals and / or metal ions are present in a constant amount.

Examples of the metal in the different metal and / or metal ion include rare earth element metals, transition metals and the like. These may be used alone or in combination of two or more.
Examples of the rare earth element metal include lanthanoids.
Examples of the lanthanoid include La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and the like.
Examples of the transition metal include metals of the IIIA, IVA, VA, VIA, VIIA, VIIIA, IB, and IIB groups.

Examples of the metal in the metal ion or metal complex include neodymium, praseodymium, erbium, europium, gadolinium, chromium, iron, manganese, nickel, cobalt, copper, rubidium, ruthenium, hafnium and the like.

The colorant preferably contains at least two different species of rare earth element metals and / or ions and at least one transition metal and / or ion. The rare earth element metal and / or ion has an atom or ionic radius larger than the atom or ionic radius of the transition metal and / or ion. Typically, the ionic radius of the rare earth element metal ion is greater than about 0.9 Å, while the ionic radius of the transition metal ion is preferably less than about 0.9 Å or less than about 0.8 Å. The size of the ionic radius usually depends on the charge and coordination number of the ion.

The content of the metal ion or the metal complex contained in the coloring liquid is not particularly limited as long as it can exhibit stability as a complex, but it is considered to realize appropriate coloring for a medical device after firing. Then, it is preferable that a sufficient amount is present, 30% by mass or less is preferable, 0.01% by mass or more and 30% by mass or less is more preferable, and 0.1% by mass or more is 20 with respect to the total amount of the coloring liquid. It is more preferably 1% by mass or less, and particularly preferably 1% by mass or more and 15% by mass or less. When the content is within the range, not only desired color reproduction can be realized, but also clogging of the inkjet nozzle due to sedimentation of the colorant can be suppressed, so that coloring modeling becomes possible with higher accuracy.

The content of the rare earth element metal and / or ion is preferably 0.05 mol / L or more and 1 mol / L or less in the coloring liquid.
The transition metal and / or ion is preferably present in the solution in an amount of 0.00001 mol / L or more and 0.05 mol / L or less.

Generally, the colorant preferably contains cations and anions. Useful anions include ^Cl- (Y = 1), ^OAc- (Y = 1), NO _3- (Y = 1), NO ^2- (Y = 1) ^{- ,} CO _{3 2-} (Y = 1) ^. ), HCO _3- ⁽ Y = 1), ^{ONC- (} Y = 1), SCN- (Y = 1), SO ₄ ² (Y = 1)-, SO ₃ ^2- (Y = 1), glutarate (Y = 1) = 2), lactate (Y = 1), gluconate (Y = 1), propionate (Y = 1), butyrate (Y = 1), glucuronate (Y = 1), benzoate (Y = 1), phenolate (Y = 1) 1), citrate (Y = 3), etc. (where Y indicates the number of coordinating atoms that can be coordinated with respect to the central metal).
Examples of the coloring agent that can be used in the coloring liquid include acetates, carbonates and chlorides of Er, Mn and Pr.

The coloring liquid preferably contains a complexing agent.
The complexing agent can form a complex with the metal ions of the colorant to help the colorant dissolve in the selected solvent and prevent the colorant from precipitating from the solution during storage. Thereby, a coloring liquid having better storage stability can be obtained.

The complexing agent capable of forming a complex with the metal of the colorant can have various shapes and structures.
The shape usually depends on the number of ligands attached to the metal, the number of bonds depends on the size, charge, and electron arrangement of the metal ions, but most metal ions have a coordination greater than one. It can have a number and various ligand structure arrangements can be obtained from the coordination number. Most shapes are listed below, but due to the use of different types of ligands, for example, due to the use of different types of ligands (which results in irregular bond distances and the coordinate atoms do not follow the on-sphere point pattern). Due to size or electronic effects, there are many cases where the regular shape deviates.
・ Straight line for 2-coordination ・ Trigonal plane for 3-coordination ・ Tetrahedron or square planar prism for 4-coordination ・ Trigonal bipyramid or trigonal prism for 5-coordination ・ Eight for 6-coordination Hedron (orthogonal) or triangular prism ・ Pentagonal bipyramid for 7 coordination ・ Tricapped trigonal prism for 8 coordination ・ Trigonal prism for 9 coordination (trigonal prism)

The complexing agent can also be used as a chelating agent (or polydentate ligand) and can bind to more than one coordination site on the central atom. The increased stability of the chelating agent is also referred to as the chelating effect.
More energy is required to increase the number of separated molecules, as all bonds to the central atom must be broken for the ligand to be completely replaced. The total number of molecules decreases when the chelate is replaced by some monodentate ligand (such as water or ammonia), while free when some monodentate ligands are replaced by the chelate. The number of molecules increases. Therefore, this effect is entropic in that more sites are used for less ligands, leaving more unbound molecules. Good results are obtained with complexing agents having at least 2, 3, 4, 5 or 6 coordinating ligands.

Examples of the chelating agent include a hexadentate ligand (Y = 6), a pentadentate ligand (Y = 5), a tetradentate ligand (Y = 4), and a tridentate ligand (Y = 3). ), Bidentate ligand (Y = 2) and the like. Here, Y indicates the number of coordinating atoms that can be coordinated with respect to the central metal.

The hexadental ligand (Y = 6) includes, for example, EDTA (ethylenediaminetetraacetic acid), 18-crown-6; 2,2,2-cryptand, polyacrylates, polyasparagates and other polymeric coordinations. Examples include children.
Examples of the pentadental ligand (Y = 5) include 15-crown-5; cyclo-pentadiene and the like.
Examples of the tetradentate ligand (Y = 4) include NTA (nitrilotriacetate), 12-crown ^- 4; triethylenetetramine, porphyrin2-, phthalocyanine2-, bis (salicylate) ethylenebis ^{(imine) salen 2 . -And} so on.
Examples of the tridentate ligand (Y = 3) include C ₃ H ₅ O (COO) ₃ ^3- .
Examples of the bidentate ligand (Y = 2) include HC ₆ H ₅ O ₇ ^2- , salicylate, glycinate, lactate, acetylacetonate, propylene diamine, and ascorbate C ₆ H ₆ O ₆ ^2- , C. ₃ H ₅ O (COOH) (COO) ₂ ^2- and the like.

Generally, in an aqueous system, a uncharged complexing ligand, a cationic ligand, and a complexing agent having an anionic functional group can be used as the complexing ligand, but the stability can be improved. A complexing agent having an anionic functional group is preferable.

The content of the complexing agent is preferably sufficient to dissolve the colorant in the solvent, for example, 2% by mass or more and 60% by mass or less with respect to the total amount of the coloring liquid. Is preferable. As a useful content, the formula: (X1 / X2) × Y is greater than or equal to 5 (where X1 is the amount of the complexing agent in [mol] and X2 is the metal ion present in the colorant. It is preferable to satisfy the formula (where Y is the number of coordinating ligands of the complexing agent used). At that time, since the coloring liquid contains at least two different metals as a part of the coloring agent, the amount of each of the existing metal ions must be added. For example, when the colorant contains 1 mol of MnCl ₂ and 2 mol of ErAc ₃ , X2 becomes 3. If the coloring liquid contains a certain amount of a particular complexing agent, and a colorant, the counterions for the metal ions present in the colorant can act as the complexing agent and therefore the complexing. The amount of agent and the amount of colorant anion must also be added. For example, if 1 mol of EDTA is used with 1 mol of citrate, then X1 will be 2.

Suitable solvents for the coloring liquid include, for example, water, alcohols such as methanol, ethanol, isopropyl alcohol, n-propyl alcohol; polar aprotonic liquids such as ketones such as acetone and ethyl acetone, alcohols and / or ketones. Examples include a mixture of water and water, a non-polar complex, and the like. Of these, water and alcohol are preferable.
Useful mixtures of solvents include, for example, water, ethanol, alcohols and / or mixtures of ketones with water. These solvents are particularly useful for polar complexes.
Examples of the non-polar complex include ethers (diethyl ether, THF, etc.) and hydrocarbons (pentane, hexane, heptane, octane, etc .; their n-, sec-, tert-isomers, etc.) and the like.

The viscosity of the coloring liquid at 25 ° C. is preferably 5 mPa · s or more and 30 mPa · s or less, and more preferably 5 mPa · s or more and 15 mPa · s or less.
The viscosity of the coloring liquid can be measured at 25 ° C. using, for example, a B-type rotational viscometer of TVB-10M manufactured by Toki Sangyo Co., Ltd.
The surface tension of the coloring liquid is preferably 40 mN / m or less, more preferably 30 mN / m or less.
The surface tension (mN / m) of the coloring liquid can be measured by the Wilhelmy method (Pt plate) at 20 ° C. using, for example, DY-300 manufactured by Kyowa Interface Science Co., Ltd.
When the viscosity of the coloring liquid and the surface tension are within the above ranges, stable ejection properties can be ensured.

<Layer forming process and layer forming means>
The layer forming step is a step of applying a modeling liquid containing zirconia particles to a predetermined region to form a zirconia layer, and is carried out by a layer forming means.

<< Zirconia layer holding means (support) >>
The zirconia layer holding means (hereinafter, may be referred to as "support") is not particularly limited as long as the liquid for modeling can be landed, and can be appropriately selected according to the purpose, and is used for modeling. Examples thereof include a table having a surface on which a liquid is placed, a base plate in the apparatus shown in FIG. 1 of JP-A-2000-328106, and the like. The surface of the support, that is, the mounting surface on which the modeling liquid is landed, may be, for example, a smooth surface or a rough surface.

<< Formation of zirconia layer >>
As a method of arranging the modeling liquid on the support, it is preferable to land it on a desired area by an inkjet head.

The inkjet head is not particularly limited as long as the modeling liquid can be landed on a desired area, and can be appropriately selected depending on the intended purpose. When the zirconia particles in the modeling liquid are likely to aggregate, for example, an inkjet head having a circulation mechanism (hereinafter, may be referred to as a “flow-through head”) is preferably used.

The flow-through head includes, for example, a plurality of pressure chambers communicated with a plurality of nozzles for ejecting droplets, a common supply flow path for supplying a liquid to the plurality of pressure chambers, and the plurality of pressure chambers. A common return flow path through which a part of the liquid in the communicating pressure chamber is returned, and an energy generating element for generating pressure in the pressure chamber are provided, and the liquid supplied from the common supply flow path to the pressure chamber is referred to as described above. A droplet ejection head that ejects a droplet from the nozzle when pressure is generated in the pressure chamber by the energy generating element while circulating to the common return flow path is preferable.

The thickness of the zirconia layer is not particularly limited and may be appropriately selected depending on the intended purpose. For example, the average thickness per layer is preferably 0.5 μm or more and 50 μm or less, and more preferably 1 μm or more and 10 μm or less. .. When the average thickness is 0.5 μm or more, the time until the medical device is obtained is appropriate, and problems such as shape loss during processing or handling such as sintering do not occur.

For example, when it is desired to develop a plurality of colors, a plurality of ink tanks and inkjet heads may be prepared. Specifically, if you want to color yellow, cyan, and magenta, you can prepare ink tanks for each color. At that time, it is preferable that the ink tank is different from the modeling liquid.

The coloring liquid is preferably applied after the zirconia layer has been dried. If the coloring liquid is applied in a state where the zirconia layer is not dried, the coloring agent may bleed and the coloring agent may move to a region other than the desired region, and the desired color reproduction may not be possible.

Further, after applying the coloring liquid to the zirconia layer, it is preferable to dry the zirconia layer once to form the next zirconia layer. If the zirconia layer is formed in a state where the coloring liquid is not dried, the zirconia particles may move and it may not be possible to form a desired shape.

<Layer drying process and layer drying means>

Examples thereof include heating with an infrared heater, laser irradiation, and natural drying. Among these, the means using a heat source is preferable from the viewpoint of productivity.

The drying time in the layer drying step can be appropriately changed. For example, if the drying time is lengthened, the lateral exudation of the coloring liquid applied in the coloring liquid applying step after the layer drying step is suppressed, and the color reproducibility is improved. On the other hand, if the drying time is shortened, the productivity is improved, but the coloring liquid applied in the coloring liquid applying step after the layer drying step causes lateral exudation, and the color reproducibility is improved. It tends to get worse. This may be appropriately selected depending on the solvent type used.

<Reaction process and reaction means>
In the reaction step, the zirconia contained in the zirconia layer and the metal ion or metal complex are formed by firing the model obtained by repeating the layer forming step and the coloring liquid applying step a plurality of times in a high temperature environment. It is a step of reacting with, and it is kept still by the reaction means.
