Description

Method for attaching artificial fingernails

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

[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 are natural nails extended, but artificial nails made of synthetic resin shaped into a desired shape are also attached and used. Such artificial nails are generally known to be used by adhering and attaching them to the tip of a 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 curvature of the artificial nails does not match the curvature of each individual's natural nails. In some cases, a strong adhesive such as a cyanoacrylate-based so-called instant adhesive is used for adhesion. Therefore, once adhered, it may become extremely difficult to peel off the artificial nails. Also, the type that adheres to the tip of a 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 laboratory work, a mold is obtained in advance to fit the shape and curvature of each individual's natural nails, and based on this mold, an artificial nail can be molded. Thus, a technology has been devised that enables an artificial nail that can be easily attached to a natural nail with an adhesive or the like and can be easily removed without using a strong adhesive. By drawing a favorite pattern or design on the artificial nail and attaching such an artificial nail onto a person's natural nail, beauty and art / nail makeup can be enjoyed. Of course, such an artificial nail is required to fit well when attached to a person's nail.

[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 artificial nails, including the nail and surrounding tissue; providing an extension base with the 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 the 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.

[0010] The artificial nail molding device of the present invention is characterized by comprising a containment container that is a rectangular parallelepiped elongated in the finger width direction so that a customer's fingers can be inserted into it, and which is equipped with a vibrating part, and an alginate impression material for obtaining a nail mold of the customer's fingers contained in the containment container.

[0011] Furthermore, the artificial nail impression device of the present invention is preferably characterized in that the vibration-adding unit applies vibration to the alginate impression material while the customer's fingers are inserted.

[0012] The artificial nail molding apparatus of the present invention is more preferably characterized in that the vibration is ultrasonic vibration.

[0013] The present invention provides a method for taking an artificial nail impression, comprising the steps of: placing an alginate impression material for obtaining a nail impression of a customer's fingers into a container that is a rectangular parallelepiped elongated in the finger width direction so that a customer's fingers can be inserted into it, and which is equipped with a vibrating attachment; and inserting the customer's fingers into the alginate impression material.

[0014] The artificial nail impression method of the present invention is preferably characterized by further comprising the step of applying vibration to an alginate impression material with a vibration-adding unit while the customer's fingers are inserted.

[0015] The artificial nail molding method of the present invention is more preferably characterized in that, in the step of the vibration application unit applying vibration, the vibration is ultrasonic vibration.

[0016] This method enables the creation of an artificial nail mold that allows for easy, rapid, and highly accurate molding of a person's nail shape in advance.

[0018] There are generally known methods for creating artificial nails. For example, the simplest method involves using commercially available artificial nails; this simply involves purchasing them and attaching them to your own nails with adhesive. Commercially available artificial nails come in various sizes and designs, offering the advantage of being able to choose one that fits your nails and your preferred design.

[0019] Another known method involves using a special gel and curing lamp to strengthen the nails and increase their length, similar to artificial nails. This method involves shaping the nails with gel, applying the gel on top, and curing it to achieve an effect similar to artificial nails.

[0020] Another method using acrylic nails involves mixing acrylic powder and monomer liquid, applying it to the nail, shaping it, and allowing it to harden. This creates a layer on your own nail that resembles a false nail. Acrylic nails are also available commercially as pre-made, ready-made nails. These pre-made acrylic nails are generally offered in different sizes and designs, and you can use them simply by gluing your preferred nail to your own nail.

[0021] Generally, these pre-made acrylic nails are pre-shaped and designed to fit the nail, and some may even include adhesive or accessories to help remove them. Pre-made acrylic nails are a convenient option for many people because they save time by eliminating the need to create them yourself using acrylic powder and monomer liquid. However, they may not fit the shape and size of your nails, so careful selection is necessary before choosing, and there is a concern that this could sometimes lead to making a mistake.

[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 the typical process is outlined below: 1. Nail Forming: 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 Design: 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 nail may be cured again after the decorative design is added. 3. Finishing and Correction: After the acrylic nail is formed and the design is added, the final finishing touches include smoothing the surface, adding gloss, and trimming any excess. The acrylic nail is 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] Custom-made nails also exist and are generally performed by nail technicians or nail artists using the following procedure: 1. Consultation: The client consults with the nail artist and communicates their desired design, style, size, etc. Bringing photos or images can help to more clearly communicate their ideal nails. 2. Measurement: The nail artist measures the size and shape of the client's nails to use as a basis for creating the 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: Based on the client's consultation and measurement information, the nail artist decides on the design, including colors, patterns, and decorations. 4. Production: The nail artist creates the custom-made nails based on the decided design. This process also includes shaping the nails using acrylic or gel. 5. Finishing: Once the artificial nails are completed, finishing work is performed. If necessary, polishing, painting, and the addition of decorations are done. 6. Delivery: Once the custom-made nails are completed, they are delivered to the client. If necessary, explanations on how to protect and care for 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, 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. Creating the custom design: Based on the obtained nail shape and size, a custom-designed acrylic nail is created. The design, color, and decorations are taken into consideration according to the customer's preferences and requests. 3. Manufacturing the acrylic nail: The custom-designed acrylic nail is manufactured. Using acrylic powder or monomer liquid, the acrylic nail is formed to match the shape of the customer's nail. 4. Fitting and adjustment: The manufactured custom acrylic nail is checked to ensure it fits the customer's nail, and fine adjustments are made as needed. This ensures that the customer can comfortably wear the acrylic nail. 5. Nail molding kit: Nail molding kits can also use soft plastic or silicone manicure stamps. These can be used to obtain the shape of one's own nails or the nails of a customer. Generally, nail molding kits include stamps of various sizes and shapes, allowing you to choose the one that best suits your own nails. 6. Templates: Artificial nail professionals and nail artists can also obtain the shape of the nail using custom-made templates. These templates are made from plastic or cardboard and are designed to accommodate different nail shapes and sizes. Nail artists can also customize these templates to fit a client's nails and 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 a typical method and necessary materials for shaping nails. 1. Nail Shaping Method: As preparation for the nails, wash them thoroughly to remove dirt and oil completely. Wipe the nails dry and ensure they are clean for cutting. 2. 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 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 to trim the corners, and fine grit 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 nail after shaping. Polishing the surface of the nail will give it a smooth finish.

[0029] When taking a shape of a nail and creating a nail mold, a nail molding kit is used, which typically includes a manicure 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 removing it, 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 (a plastic mold) is selected for obtaining the nail impressions. A separate 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 creamy consistency, 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's finger characteristics can be clearly expressed. On the other hand, with silicone impression material, concerns such as powder scattering can be reduced. Also, since silicone impression material has lower fluidity than alginate impression material and tends to become a harder putty during the hardening process after mixing, it is necessary to press harder when obtaining finger and nail molds, and to remove the fingers with greater care.

[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 impressions of artificial nails. The following describes the general procedure for obtaining a nail impression using the alginate impression material of this invention. Cleanse the customer's fingertips and trim the natural nails to an appropriate length. Before taking the nail impression, 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 separate 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] Wait in this state until the alginate impression material hardens while stationary. The curing time varies depending on the type and manufacturer of the impression material, but it is usually a few minutes. Once the nail form has hardened sufficiently, carefully remove the tray from your hand. At this time, it is necessary to be careful not to injure your fingertips or nails. The obtained nail form is stored using an appropriate storage method and is sent to a nail technician or nail artist as needed to create artificial nails.

[0044] To select an appropriate tray, the tray for obtaining the nail form (containing the alginate impression material) needs to fit the customer's fingertip form. If the tray does not fit properly, there is also concern that the accuracy of the nail form may decrease. For this reason, the tray should have an opening of sufficient size that allows for easy insertion and removal of the hand, and should have a structure that allows volatile components (such as evaporated moisture, etc.) to be easily dispersed so that the impression material dries easily. For example, it can be a rectangular or cuboid tray with an all-open top surface. In the thickness direction of the hand, it is short to match the shape of the hand, and in the width direction of the hand, it is long enough for all fingers to be inserted with the fingers slightly spread, and it is preferable to adopt a shape like this.

[0045] It is important to accurately follow the mixing ratio and mixing time of the impression material to be used. If the mixing is uneven or the mixing time is insufficient, the accuracy of the nail form may decrease. Also, when obtaining the nail form, it is important to accurately 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 and before it has hardened too much. Furthermore, at the same time as inserting the fingers into the tray containing the impression material, by applying ultrasonic vibration and utilizing that vibration, the impression material can penetrate into the details and fine gaps of the fingers and nails, reducing the entrapment of air bubbles and making it possible to obtain a more detailed nail form. It is preferable to apply the ultrasonic vibration until just before the impression material begins to harden slightly. Also, it is acceptable to apply normal vibration (for example, a vibration frequency of 5000 - 13000 RPM used in an electric massager) together with or instead of the ultrasonic vibration. This can reduce the concern of air bubbles being trapped in the impression material.

[0046] Also, in order to effectively penetrate and conform the gel or paste of alginate impression material into the detailed parts of the nail tip, low-frequency vibration is more preferably used as the effective vibration. Low-frequency vibration is a relatively slow vibration that gently shakes substances and is effective in allowing liquids or viscous substances such as gels and pastes to penetrate into the detailed parts.

[0047] Such vibration helps to spread the gel or paste of alginate impression material uniformly or penetrate and diffuse it uniformly on the surface of the nail. Also, low-frequency vibration can process substances without causing excessive pressure or friction, so it can minimize damage and deformation of the material. From the above viewpoints, in order to penetrate and diffuse the gel or paste of alginate impression material accommodated in the tray into the detailed parts of the nail and make it conform, it is most effective to use low-frequency vibration.

[0048] The frequency of the vibration used to penetrate the gel or paste of alginate impression material into the detailed parts is preferably in the range of several tens of Hertz to several kilohertz. Specifically, it is preferably within the range of 20 Hz to 20 kHz. The vibration number or frequency is preferably adjusted according to the viscosity of the gel or paste of the alginate impression material used. For example, when penetrating a highly viscous gel or the like, low-frequency vibration is used, while when it is necessary to proceed with the work more quickly or when more fine penetration is required, it is preferable to select a higher-frequency vibration.

[0049] Ultrasonic vibration is an effective means for penetrating gels and the like into the detailed parts. Ultrasonic waves generally mean high-frequency vibrations of 20 kHz or more, and their high-frequency vibrations have the characteristic of easily penetrating into fine gaps and structures inside substances. By using ultrasonic vibration, highly viscous substances such as gels can be effectively penetrated and spread uniformly to the surface and fine regions of the nail. Also, since ultrasonic waves can usually control the pressure or force applied to substances by minute changes in amplitude, it is possible to perform diffusion and penetration treatment without damaging the substances.

[0050] Figure 1 shows a plaster mold in which the shape of the nail 1010 is clearly visible after obtaining a mold of the customer's fingertip, and 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, but this is intentionally left in place without being removed in order to protect the shape of the fingertip nail from damage, as it is held in the narrow space between the fingers. Even in this way, 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 the finger thickness direction (depth direction on the paper) only needs to be sufficient for the finger to be inserted smoothly, and the finger length direction (depth direction / up-down direction on the ground) only needs to be deep enough to obtain the shape of the fingernail at the tip of the finger.

[0052] The components, mixing method, and adjustment 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 tube as a pre-mixed compound 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 hardening process, while colder water may slow it down. Furthermore, the hardening 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 gypsum, 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.

[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 are 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 transmission 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 have a structure that releases bubbles into the water. 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 Embodiments) Figures 4 to 8 illustrate variations of embodiments, 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 for mixing, a spatula (any kind of spatula) 40, an anhydride 50, and a vibrator 70. The vibrator 70 is used to remove air bubbles that may be mixed into the paste-like material, and is preferably vibrated at 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 according to 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, offering the advantage of preventing 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 such as plaster and resin, which are prone to air bubble formation, 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 thoroughly mix the mixture within a range that does not cause the alginate impression material 10 to harden, in order to eliminate lumps and air bubbles and to perform a more accurate nail mold.

[0066] In step 3 of Figure 9 and in 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 step 4 of Figure 9 and in 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 step 5 of Figure 9 and in 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 step 8 of Figure 9 and in 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.
