Description

Technical Field

[0001] The present invention relates to a method for attaching artificial nails.

Background Art

[0002] For a long time, nail art has often been performed to beautify and decorate the nails of fingers by extending the nails and shaping them into beautiful shapes. Not only the natural nails are extended, but also synthetic resin artificial nails shaped into desired shapes are attached and used. Such artificial nails are generally known to be used by adhering and attaching them to the tip of the natural nail and by adhering them to the entire natural nail.

[0003] These artificial nails are often uniformly shaped, and it often happens that the artificial nails do not fit the curvature of each individual's natural nails. In some cases, a strong adhesive such as a so-called instant adhesive of the cyanoacrylate type is used for adhesion. Therefore, once adhered, it may be extremely difficult to peel off the artificial nails. Also, the type that adheres to the tip of the natural nail takes time for adhesion, and fine adjustment and correction for matching the natural nail part are often required.

[0004] On the other hand, by applying the technology in dental technology, the mold is obtained in advance so as to fit the shape and curvature of each individual's natural nail, and by molding the artificial nail based on the mold, an artificial nail that can be easily attached to the natural nail with an adhesive or the like without using a strong adhesive and can be easily detached has been devised. By drawing a favorite pattern or design on the artificial nail and attaching such an artificial nail on a person's natural nail, beauty and art / nail makeup can be enjoyed. Of course, such artificial nails are required to fit well when attached to a person's nails.

[0005] Patent Document 1 below proposes a method for producing artificial nails, which involves creating a plaster model from a precise impression of the fingertip area of ​​a person who wishes to wear an artificial nail, including the nail and surrounding tissue; providing an extension base with a desired length, shape, and curvature on the tip of the plaster model using wax; taking an impression of the master model and creating a plaster model of the impression surface to make a duplicate model; forming an artificial nail model of a desired shape on the nail portion of the duplicate model; taking an impression mold of this model; forming an artificial nail using a curable resin composition between this impression mold and the duplicate model from which the artificial nail model has been removed; and then performing a finishing treatment.

[0006] Furthermore, the aforementioned publicly available document also proposes a kit for producing artificial nails, which is comprised of a curable resin composition and at least one material or tool selected from the group consisting of gypsum, wax, impression material, polishing tools for finishing, mold release agent for cured resin, adhesive for attaching artificial nails, and remover for attaching and removing artificial nails.

[0007] Furthermore, Patent Document 2 below proposes a method for manufacturing artificial nails that can be manufactured remotely and that fit well to a person's nails. The method includes the steps of: a first person packing a first dental silicone impression material into a protective device; a first person pressing the first dental silicone impression material packed in the protective device onto the first person's nail through the protective device to manufacture a nail mold of the first person's nail; a second person packing a second dental silicone impression material, which is harder than the first dental silicone impression material, into the nail mold to manufacture a finger model of the first person having a nail portion; a second person applying a first gel onto the nail portion; a second person applying a second gel, which has higher self-leveling properties than the first gel, onto the first gel; and a second person peeling the artificial nail obtained by the hardening of the first and second gels from the finger model.

[0009] When attaching artificial nails, using existing mass-produced, off-the-shelf artificial nails can result in a lack of conformity to the individual nail shape of each person, leading to concerns about quality issues such as gaps, poor fit, premature peeling, and the need for excessive adhesive. On the other hand, when attempting to obtain individual nail molds for the production of custom-made artificial nails, it has traditionally been difficult to obtain highly accurate molds on-site in a short time, requiring considerable time and resulting in long waiting times and considerable effort. This invention was made in view of the above-mentioned problems and aims to propose an artificial nail molding method that enables easy, rapid, and highly accurate molding of a person's nail shape in advance. [Means for solving the problem]

Embodiments for Carrying Out the Invention

[0018] Generally, there are multiple known methods of creating artificial nails. For example, when using commercially available artificial nails as the simplest method, one only needs to purchase commercially available artificial nails and adhere them to one's own nails using an adhesive or the like. Since commercially available artificial nails are available in various sizes and designs, there is an advantage that one can choose those that fit one's own nails or a design of one's preference.

[0019] Also, as gel nails, there is a known method of increasing the length by strengthening the nails using a special gel and a curing lamp. In this method, by using the gel to shape one's own nails, applying the gel thereon, and curing it, an effect similar to artificial nails can be obtained.

[0020] Also, in the method of using acrylic nails, an acrylic powder and a monomer liquid are mixed and applied to the nails, shaped, and cured. Thereby, a layer similar to artificial nails can be created on one's own nails. Also, acrylic nails are pre-made and commercially available as ready-made nails. These pre-made ready-made acrylic nails are generally provided in different sizes and designs, and can be used simply by adhering the preferred nails to one's own nails.

[0021] Generally, these pre-made acrylic nails are processed to shape and design the nails, and some pre-made acrylic nails may also include adhesives and accessories useful for removing the artificial nails. Pre-made acrylic nails can save the trouble of making them oneself using acrylic powder and monomer liquid, and are a convenient option for many people to save time. On the other hand, since they may not fit the shape and size of one's own nails, one needs to choose carefully before selection, and there is also a concern that it may lead to a selection mistake sometimes.

[0022] Additionally, when using natural nails, it's possible to grow your own nails to achieve a similar effect to artificial nails. However, growing natural nails long enough can take time, and there's also the risk of them breaking or chipping.

[0023] Pre-made acrylic nails are typically produced in the professional beauty industry, and a typical process outline is as follows: 1. Nail Formation: First, the shape of the acrylic nail is created using acrylic paste, which is made by mixing acrylic powder and monomer liquid. The acrylic paste is poured into a mold of a specific shape and cured to achieve the desired shape. 2. Adding Designs... It is also possible to add designs and decorations to acrylic nails. For example, they can be decorated in various ways, such as by drawing, adding rhinestones, or using stickers, and the acrylic nails can be cured again after the decorative designs have been added. 3. Finishing and Correction: After the acrylic nails are formed and the design is added, the final finishing touches include smoothing the surface, adding gloss, and trimming any excess. The acrylic nails are corrected as needed to ensure a perfect finish. 4. Packaging... Finally, the pre-made acrylic nails are packaged. Each acrylic nail is packaged in the appropriate size and design, ready for sale.

[0024] In addition, custom-made nails also exist, and are generally performed by nail technicians or nail artists using the following procedure. 1. Consultation: Consult with the nail artist and communicate your desired design, style, size, etc. Bringing photos or images will help you communicate your ideal nails more clearly. 2. Measurement... Nail artists measure the size and shape of the client's nails to use as a basis for creating custom-made nails. If necessary, several adjustments and fittings may be performed. When measuring the size and shape of the client's nails, the artificial nail molding method of the present invention can be used, which enables more precise and faster nail molding. 3. Design... The nail artist determines the design, including colors, patterns, and decorations, based on information gathered from the client's consultation and measurements. 4. Production... The nail artist creates custom-made nails based on the decided design. This process includes shaping the nails using acrylic or gel. 5. Finishing... Once the artificial nails are complete, the finishing work is done. This includes polishing, painting, and adding decorations as needed. 6. Handover...Once the custom-made nails are completed, they are handed over to the customer. If necessary, instructions on how to protect and care for the nail art will also be provided.

[0025] Custom-made nails are created to suit individual needs and preferences, resulting in a more perfect fit and design than other nail products. Typically, when creating custom acrylic nails, the shape and size of the client's nails are obtained using an artificial nail molding method. This is a crucial process for creating custom-designed acrylic nails that perfectly fit the client's nails, and it follows the steps outlined below.

[0026] 1. Obtaining the nail shape... To accurately obtain the shape and size of the nail, a dedicated nail molding kit or template, or the artificial nail molding method of the present invention, is used. This allows for obtaining precise dimensions for creating custom-designed acrylic nails that match the shape and size of the customer's nails. 2. Creation of custom designs: Based on the shape and size of the nails obtained, custom-designed acrylic nails are created. The design, colors, and decorations are tailored to the customer's preferences and requests. 3. Acrylic Nail Production...Custom-designed acrylic nails are produced. Using acrylic powder and monomer liquid, the acrylic nails are shaped to match the customer's nail shape. 4. Fitting and Adjustment: The custom-made acrylic nails are checked to ensure they fit the customer's nails, and any necessary adjustments are made. This ensures that the customer can wear the acrylic nails comfortably. 5. Nail Shaping Kit... Nail shaping kits can also be used with soft plastic or silicone nail stamps. These can be used to capture the shape of your own nails or those of your clients. Generally, nail shaping kits include stamps of various sizes and shapes, allowing you to choose the one that best suits your own nails. 6. Templates... Nail professionals and nail artists can also use custom-made templates to capture the shape of the nail. These templates are made of plastic or cardboard and are designed to accommodate different nail shapes and sizes. Nail artists can customize these templates to fit a client's nails and then create acrylic nails based on them.

[0027] By using these nail molding kits, methods, templates, etc., nail artists can accurately capture the shape of a client's nails and create custom-made acrylic nails that fit more precisely and stably for a longer period of time.

[0028] The following describes typical methods and necessary materials for shaping nails. 1. How to shape your nails: To prepare your nails, wash them thoroughly to remove any dirt or oil. Wipe your nails dry and cut them to a clean state. 1. Shaping... To shape the nails, use nail clippers to trim them to the desired length. Nail clippers can be used to trim the tips of the nails. Also, use a nail file to shape the nails. There are various types of nail files, from coarse grit to fine grit, and you can choose and use the appropriate type as needed. It is preferable to use a file with a grit that matches the shape of the nail. Generally, coarse grit is used to round the tips of the nails, medium grit is used to trim the corners, and fine grit is used for finishing. Also, use a buffer to smooth the surface of the nails. This will even out the surface of the nails and remove any shine. Furthermore, use a cut cleaner to remove dirt and oil around the nails and keep the nails clean before shaping. Preferably, as a finishing touch, smooth the edges of the nails after shaping is complete. Polishing the surface of the nails will give a smooth finish.

[0029] When taking a shape of a nail to create a nail mold, a nail molding kit is used, which typically includes a nail stamp or template made of a specific material (usually soft plastic (a soft material made from polymers such as polyvinyl chloride (PVC) or polyurethane) or silicone). In this invention, alginate impression material is used. This kit is used to obtain a nail mold.

[0030] First, select a stamp of the appropriate size for your nail and fit it to the shape of your nail. Press the stamp onto your nail to create a mold of your nail. This will imprint the shape of your nail onto the stamp. Next, use this stamp to create a nail mold using the appropriate material (usually acrylic or gel).

[0031] Additionally, a dial-type nail mold can be used, which is a tool for accurately measuring and recording the shape of your nails. Using a dial-type nail mold, you can accurately measure and record the shape and size of your nails. Based on the measured shape and size, a professional nail technician can create a custom-made nail mold.

[0032] The advantage of using double-sided tape to attach nail tips is that they can be attached and removed multiple times and are gentler on the nails compared to glue. However, a disadvantage is that they can easily come off due to impact. On the other hand, attaching them with nail glue (adhesive) has the advantage of being impact-resistant and less likely to come off, but the disadvantages are that it takes time to remove them and they cannot be reused multiple times.

[0033] Additionally, when using double-sided tape to attach nail tips, you will need nail tips, double-sided tape, and a nail file. When choosing a tip to fit your nail, the key to determining the size is the width of the tip. Next, file the tip to match the shape of your nail, adjusting the curve and width at the base of the nail. Then, apply double-sided tape to the back of the tip. Next, trim any excess tape. Finally, align the tip with the base of your nail and attach it, tilting it towards the tip.

[0034] There are several types of adhesives used to attach nail tips, but here we will explain in detail the method using nail glue (adhesive). To attach nail tips using nail glue, prepare your natural nails by trimming them short. Long nails can prevent the tips from adhering properly. Adjust the nail tip to match the shape of your natural nail with a file. Then, apply the glue, spreading it evenly over the entire tip, being careful not to let it spill over the edges.

[0035] Next, when attaching the tip, place it on the nail, aligning it with the cuticle line, being careful not to trap any air. Ensure the tip is straight and not tilted as you adhere it. Then, allow it to dry. Press the tip firmly against the nail and let it dry for 2-3 minutes. Drying time may vary depending on the drying progress of the glue, as well as ambient conditions such as temperature.

[0036] Nail glue has strong adhesive properties, so when applied correctly, it securely fixes the nail tips in place, and when removed, it can be carefully removed using a solvent such as acetone. UV-curing gel can be cured using a UV lamp.

[0037] Next, we will outline the procedure for obtaining nail impressions using silicone impression material or the alginate impression material of the present invention. First, the customer's fingertips are thoroughly cleaned. Before obtaining the nail impressions, any dirt on the nails and finger surfaces is thoroughly removed. The nail artist or other professional observes the condition of the fingertips and nails and plans an appropriate method for obtaining the impressions. In some cases, necessary treatments may be performed before taking the nail impressions. A tray (plastic mold) is selected for obtaining the nail impressions. Each tray is used to obtain nail impressions for both the left and right hands.

[0038] The silicone impression material or the alginate impression material of the present invention is filled into the tray. Silicone impression material usually hardens by mixing two components: a base and a catalyst. In this case, it is necessary to adhere to the correct mixing ratio and mixing time. On the other hand, in the case of alginate impression material, it is necessary to knead the powder into a cream, so care must be taken when handling it to prevent the powder from scattering. However, when obtaining a mold using alginate impression material and plaster, the individual characteristics of the finger can be clearly expressed. On the other hand, with silicone impression material, concerns such as powder scattering can be reduced. Furthermore, silicone impression material has lower fluidity than alginate impression material and tends to harden into a firmer putty during the hardening process after mixing. Therefore, when obtaining finger or nail molds, stronger pressure is required, and greater care must be taken when removing the fingers.

[0039] The client is instructed to insert their fingertip into the tray and hold it in the correct position. During this time, the client is instructed to relax. Wait for the silicone impression material to harden. Hardening time varies depending on the type and manufacturer of the impression material, but is usually several minutes. Once the nail mold has hardened sufficiently, carefully remove the hand from the tray. Care must be taken not to injure the fingertip. The obtained nail mold is stored in an appropriate manner and, if necessary, sent to a nail technician or nail artist to create appropriate artificial nails.

[0040] Alginate impression material is one of the impression materials commonly used in dental care, but in this invention, its use is specifically for taking molds of artificial nails. The following describes the general procedure for obtaining a nail mold using the alginate impression material of this invention. Clean the customer's fingertips and trim the natural nails to an appropriate length. Before taking the nail mold, thoroughly remove any dirt from the surface and between the natural nails and nail tissue.

[0041] The nail technician or nail artist will examine the inside of the fingertip and plan the appropriate acquisition method. In rare cases, necessary nail treatment may be performed before taking the nail impression. Prepare the alginate impression material in the appropriate mixing ratio. Typically, the impression material is prepared by mixing alginate powder with water. In this case, it is preferable to adhere to the exact mixing ratio and mixing time.

[0042] The impression material is filled into a tray (a plastic nail mold). Preferably, one tray is used to obtain a nail mold for each hand. The customer's hand is placed in the tray and held in the appropriate position. At this time, the customer should relax to ensure a stable impression is taken. A wrist restraint may be used to prevent the hand from trembling or moving unintentionally due to tension.

[0043] Remain still in this position and wait for the alginate impression material to harden. The hardening time varies depending on the type and manufacturer of the impression material, but it is usually a few minutes. Once the nail mold has hardened sufficiently, carefully remove the tray from your hand. Take care not to injure your fingertips or nails during this process. The obtained nail mold is stored in an appropriate manner and, if necessary, sent to a nail technician or nail artist to create artificial nails.

[0044] To select the appropriate tray, the tray used to obtain the nail impression (containing the alginate impression material) must conform to the shape of the customer's fingertip. If the tray does not fit properly, there is a concern that the accuracy of the nail impression may decrease. For this reason, the tray should have an opening large enough to easily insert and remove the hand, and a structure that allows volatile components (such as evaporated water) to dissipate easily so that the impression material dries quickly. For example, it can be a rectangular or cuboidal tray with the entire top surface open, and it is preferable to adopt a shape that is short in the thickness direction of the hand and long in the width direction of the hand so that all fingers can be inserted with the fingers slightly spread, so as to conform to the shape of the hand.

[0045] It is crucial to precisely adhere to the mixing ratio and mixing time of the impression material used. If the mixing is uneven or the mixing time is insufficient, the accuracy of the nail mold may decrease. Furthermore, when obtaining the nail mold, it is important to precisely follow the curing time instructed by the nail technician or nail artist. It is important to remove the fingers from the tray before the impression material is completely cured but before it becomes over-cured. Additionally, by applying ultrasonic vibrations simultaneously with inserting the fingers into the tray containing the impression material, the impression material can penetrate into the fine details and tiny gaps of the fingers and nails, reducing the risk of trapped air bubbles and allowing for the acquisition of a more precise nail mold. It is preferable to apply ultrasonic vibrations until the impression material begins to slightly harden. Alternatively, ordinary vibrations (e.g., vibration frequencies of 5000-13000 RPM used in electric massagers) may be added along with or instead of ultrasonic vibrations. This reduces the concern of trapped air bubbles in the impression material.

[0046] Furthermore, low-frequency vibration is more preferably used as an effective vibration for penetrating and blending alginate impression material gels and putties into the fine details of the nail tip. Low-frequency vibration is a relatively slow vibration that gently agitates the material, making it effective for penetrating liquids and viscous substances such as gels and putties into the fine details.

[0047] Such vibrations help to evenly spread alginate impression gels and putties and to penetrate and diffuse them evenly across the nail surface. Furthermore, low-frequency vibrations can process materials without generating excessive pressure or friction, thus minimizing damage and deformation of the material. From the above perspective, using low-frequency vibrations is the most effective way to penetrate, diffuse, and blend alginate impression gels and putties contained in a tray into the intricate details of the nail.

[0048] The frequency of vibration used to penetrate alginate impression gels or putties into fine details is preferably in the range of tens of hertz to several kilohertz. Specifically, it is preferable to use a frequency within the range of 20 Hz to 20 kHz. The vibration frequency is preferably adjusted according to the viscosity of the alginate impression gel or putty used. For example, when penetrating highly viscous gels, low-frequency vibrations are used, while when it is necessary to proceed more quickly or when finer penetration is required, it is preferable to select higher-frequency vibrations.

[0049] Ultrasonic vibration is an effective method for penetrating gels and other substances into fine details. Ultrasound typically refers to high-frequency vibrations of 20 kHz or higher, and these high-frequency vibrations have the property of easily penetrating even the minute gaps and structures within materials. By using ultrasonic vibration, highly viscous substances such as gels can be effectively penetrated and spread uniformly to the surface and fine areas of the nail. In addition, since the pressure and force applied to the material can usually be controlled by minute changes in amplitude, it is possible to diffuse and penetrate the material without damaging it.

[0050] Figure 1 shows a plaster mold in which the shape of the nail 1010 is clearly visible, obtained by taking a mold of the customer's fingertip. Figure 2 illustrates the process of creating an artificial nail 1020 using the shape of the nail 1010 and temporarily attaching it. By obtaining the shape of the nail 1010 in advance and forming a fingertip model as shown in Figure 1 using plaster or the like, it becomes possible to easily and accurately create the artificial nail 1020 as shown in Figure 2 based on this model. Note that in Figures 1 and 2, impression material remains as if held between the fingers. This is because the impression material, which is held in the narrow space between the fingers to protect against damage to the fingertip nail shape, is intentionally left in place without being removed. Even in this manner, there is no obstacle in understanding the shape of the nail located on the outside of the finger and creating the artificial nail.

[0051] Figure 3 illustrates an embodiment of the present invention in which a finger 1000 is inserted into an alginate impression material 3000 contained in a containment container 2000 equipped with a vibration-adding unit 4000, typically an ultrasonic device, to take an impression. As shown in Figure 3, the containment container 2000 has the shape of a rectangular parallelepiped that is long in the finger width direction (left-right direction on the paper), but in the finger thickness direction (depth direction on the paper), it is sufficient that the finger can be inserted smoothly, and in the finger length direction (depth direction / up-down direction on the ground), it is sufficient that the shape of the fingertip nail can be obtained.

[0052] The components, mixing method, and adjustments of Alginate Impression Material 3000 can be the same as those used for obtaining dental impressions as dental materials. It allows for the creation of custom-made, perfectly fitting artificial nails tailored to the unique nail shapes of each individual. Alginate Impression Material 3000 is particularly suitable for obtaining nail impressions because its viscosity and hardness can be easily and arbitrarily adjusted, as can its curing speed (e.g., slow, normal, fast). For example, the pH can be changed, or a curing accelerator can be used. By setting the pH of Alginate Impression Material 3000 to 9.4-9.8, a beautifying effect on the fingertips, similar to that of an alkaline hot spring, can be expected.

[0053] The components of alginate impression material 3000 may include sodium alginate, potassium alginate, diatomaceous earth, calcium sulfate, liquid paraffin, colorants, fragrances, etc., as well as agar. The powder components of the alginate impression material may also include sodium alginate or potassium alginate as gel-forming components, calcium sulfate (CaSO4) as a reactant for forming calcium alginate gel, agar as a filler, zinc oxide as an additive, retarders used to extend working time (e.g., sodium phosphate), fragrances to improve customer comfort, etc.

[0054] Alginate impression material 3000 may be prepared on-site as a mixture of powder and liquid, or it may be contained in a pre-mixed tube and dispensed as needed, like toothpaste. When mixing on-site, it is important to mix the powder and liquid uniformly, and this can be done carefully using a clean mixing bowl or spatula. In addition, when adjusting the water temperature, using warm water (approximately 30-40°C) will speed up the curing process, while colder water may slow it down. Furthermore, the curing speed of alginate impression material is affected by pH.

[0055] To accelerate the curing speed of alginate impression materials, the water temperature can be increased when mixing the alginate impression material powder and liquid. Warm water promotes the chemical reaction, shortening the curing time. Alternatively, fast-set type alginate impression materials may be used. Some alginate impression materials are designed as "fast-set" versions and may contain additives that accelerate the curing process. Also, prolonged mixing of alginate impression material powder and liquid may slow down the curing process. Using a thinner mixture may result in faster curing than a thicker mixture. Accelerators may be added, and additives may be mixed with the powder using an accelerator for alginate impression materials to shorten the curing time.

[0056] Fast-set type alginate impression materials may also be alginate impression materials specifically designed for automatic mixing machines. These materials have good compatibility with water and are easy to mix, forming a uniform paste in about 20 seconds, resulting in a smooth paste free of air bubbles and lumps. They also have excellent moisture retention after gelling, improving dimensional stability, and have excellent adhesion to agar impression materials, making them suitable for combined impressions. Furthermore, they have good compatibility with various types of plaster, resulting in models with smooth surfaces, making them suitable for precise impression taking.

[0057] Fast-setting alginate impression materials with rapid curing speeds include Alflex Dust-Free Type and AROMA FINE MIXER TYPE, among others.

[0058] Furthermore, the application of ultrasonic vibrations may utilize bubbles generated or discharged into a liquid such as water. Typically, when nanobubbles are generated in water, ultrasonic waves are generated when the nanobubbles burst and disappear in the water, and these ultrasonic waves can be transmitted from the water to the impression material. Even bubbles with a larger diameter than nanobubbles, such as microbubbles, will generate vibrations or ultrasonic waves when they burst and disappear in water, so the system can be configured to transmit these vibrations or ultrasonic waves to the impression material, for example, by placing the liquid adjacent to the impression material or by transmitting the vibrations via a transmitting material.

[0059] Such vibrations and ultrasound are more easily transmitted when the impression material is gel-like, semi-liquid, or putty-like and has not yet fully hardened. This helps remove small air bubbles and other imperfections from the fine shape and structure of the nail, allowing the impression material to penetrate and spread sufficiently. On the other hand, as the impression material hardens, the application of vibrations and other signals can be reduced or stopped.

[0060] For example, the vibration-adding unit 4000 may be filled with a liquid such as water, and a structure that releases bubbles into the water may be used. By continuously or intermittently releasing bubbles into the water, similar to a bubble massage bath or aeration in aquariums for tropical fish, ultrasonic vibrations are generated in the vibration-adding unit 4000 when the bubbles disappear. In this case, air vents or exhaust ducts may be placed above and around the vibration-adding unit 4000.

[0061] (Variations of the embodiment) Figures 4 to 8 illustrate variations of the embodiment, and Figure 9 is a flowchart illustrating the nail molding method and procedure for a variation embodiment.

[0062] As shown in Figure 9 Step 1 and Figure 4(a), first prepare the alginate impression material 10, a specified amount of water 20 to be mixed with it, a rubber bowl 30, a spatula (any kind of spatula) 40, an anhydride 50, and a vibrator 70 for mixing. The vibrator 70 is used to remove air bubbles that may be mixed into the paste-like material, and it is preferable that the vibration is 3000 to 6000 rpm (revolutions / minute), but a standard dental vibrator of any frequency can also be used. The hardening speed of the alginate impression material 10 can be adjusted by the temperature of the water 20 used for mixing, so for example, cold water can be used if you want to slow down the hardening speed.

[0063] A dental vibrator is a device used in dental treatment and laboratory work, primarily for mixing and pouring plaster and dental resins. This device helps remove air bubbles and create a uniform and smooth material by applying minute vibrations. Its main uses include ensuring that the plaster used for casting dental impressions flows uniformly into the mold without air bubbles by applying vibrations, and when dental technicians create prosthetics such as crowns and bridges, they use it to uniformly mix materials and remove air bubbles.

[0064] Dental vibrators typically have a vibration frequency set in the range of approximately 3,000 to 6,000 revolutions per minute (RPM). However, some products allow for frequency adjustment, enabling users to set the optimal frequency depending on the material being processed and the nature of the work. For example, a low frequency of 3,000 revolutions per minute is suitable for delicate work and mixing of fine materials, as it prevents excessive movement of the material when removing air bubbles. On the other hand, a high frequency of 6,000 revolutions per minute is suitable for processing highly fluid materials that easily form air bubbles, such as plaster and resin, allowing for thorough bubble removal in a short time.

[0065] As shown in Figure 9 Step 2 and Figure 4(b), the alginate impression material 10 and water 20 are thoroughly mixed in the rubber bowl 30 for approximately 30 to 40 seconds. At this time, if lumps are formed or remain, they will affect the subsequent molding process, so the mixture should be thoroughly mixed until no lumps are present. The above mixing time is a typical guideline, and it is preferable to mix thoroughly within the range where the alginate impression material 10 does not harden, in order to eliminate lumps and air bubbles and to perform a more accurate nail mold.

[0066] In Figure 9 Step 3 and Figure 5(a), a rubber bowl 30 containing the kneaded alginate impression material 10 is placed on the vibrator 70. The vibration of the vibrator 70 removes any remaining air bubbles that have been mixed into or generated in the alginate impression material 10, and the fingers 60 to be molded are then inserted into the alginate impression material 10. In this case, the time for removing the remaining air bubbles that have been mixed into or generated in the alginate impression material 10 by the vibration of the vibrator 70 is preferably about 2 to 4 minutes, and more preferably about 3 minutes, with the fingertips inserted. This is preferable from the viewpoint of removing air bubbles, accurate molding, and work efficiency.

[0067] In Figure 9 Step 4 and Figure 5(b), the alginate impression material 10 hardens approximately 3 minutes after the insertion of the fingers 60, so the fingers 60 are gently removed from the alginate impression material 10. At this time, it is important to remove the fingers carefully so as not to damage or deform the nail shape remaining in the alginate impression material 10. It is preferable to continuously apply vibration from the vibrator 70 to the rubber bowl 30 for approximately 3 minutes after the insertion of the fingers 60.

[0068] In Figure 9 Step 5 and Figure 6(a), the hard gypsum 50 and spatula 40 are prepared.

[0069] As shown in Figure 9 Step 6 and Figure 6(b), water 20 is mixed into the anhydrite 50 and the vibration of the vibrator 70 is applied while mixing. By placing the mixing container on the vibrator 70 and mixing the water 20 into the anhydrite 50 using a spatula 40, appropriate vibrations are applied to the anhydrite 50, allowing the mixing process to be carried out while expelling air bubbles contained within the anhydrite 50. Furthermore, when multiple people are working on the process, it is possible to perform steps 5 and 6 simultaneously with step 4.

[0070] As shown in Figure 9 Step 7 and Figure 7(a), the hard plaster 50 prepared in Step 6 is poured little by little into the finger mold of the alginate impression material 10 prepared in Step 4. In this case, it is preferable to pour the hard plaster 50 while applying vibration by placing the container on a vibrator 70. This ensures that vibration is constantly applied during the pouring process. This makes it possible to more reliably remove any air bubbles that may remain in the hard plaster 50 and to ensure that the hard plaster 50 reaches even the fine details of the finger mold, such as the fingertip, for more reliable filling. This makes it possible to obtain an even more precise nail mold.

[0071] As shown in Figure 9 Step 8 and Figure 7(b), after pouring in all of the hard gypsum 50, the container is placed on a vibrator and vibrated for about 5 minutes to allow the hard gypsum 50 to reach every corner of the recesses of the alginate impression material 10 and to remove any trapped air bubbles. This time is preferably about 4 to 6 minutes, but about 5 minutes is most preferable from the viewpoint of efficient work progress, ensuring that the hard gypsum 50 reaches into the fine details and more completely removing any remaining air bubbles in the hard gypsum 50.

[0072] As shown in Figure 9 (Step 9) and Figure 8, it is presumed that the hard gypsum 50 has hardened completely after approximately one hour or more has elapsed since step 8. Therefore, after confirming that the hard gypsum 50 has hardened completely, the molded finger mold 51 can be removed from the alginate impression material 10 or the alginate impression material 10 can be peeled off and removed.
