今まで出願された特許文献には、適度な復元力をもつ小片を巻き爪表面に貼り付け、巻き爪を徐々に正常な形態に矯正する巻き爪矯正具(特許文献１)、変形爪の幅方向端部にかけた一対の折返し端に弾性力を付与して引っ張る巻き爪矯正具(特許文献２)、変形方向と反対方向の引張り力を爪の両側端縁に加える矯正具(特許文献３)、結晶方位が揃った実質的にβ 単相からなる再結晶組織を有する冷間加工により作製されたＣｕ -Ａ ｌ -Ｍ ｎ 系形状記憶合金材の加工方向に長手方向を揃えて切り出され、長手方向に関する形状記憶能が大きく幅方向に関する変形応力が高いほぼ短冊状の弾性金属片を素材としている(特許文献４)がある。 The patent documents filed so far include a curly nail correction tool (patent document 1) for applying a small piece having an appropriate restoring force to the surface of the wound nail and gradually correcting the wound nail to a normal form, and the width of the deformed nail. A wound nail corrector that applies an elastic force to a pair of folded ends applied to the ends in the direction (Patent Document 2), and a corrector that applies a tensile force in the opposite direction to the deformation direction to both side edges of the nail (Patent Document 3) The Cu-A l -M n type shape memory alloy material produced by cold working having a recrystallized structure consisting essentially of a β single phase with aligned crystal orientations, and cut out with the longitudinal direction aligned.

非特許文献１は、新製品開発における試作品を、迅速かつ安価に製造するニーズが高まり、三次元ＣＡＤデータより求められた薄い層状物を積み重ね接合して立体創生する積層もので、米国を中心に開発され発展してきたものである。その後、図２に示すような光造形法以外の方法が開発されてきて積層造形法となっている。この積層造形法の特徴は、
（１） 切削加工では、加工条件の選択、ＣＡＤ／ＣＡＭデータ作成に熟練を要し、ワークの持ち換えを含め、かなり長時間の加工を要する。しかし、積層造形では、３次元ＣＡＤデータが存在しさえすれば、多くの作業が自動化され、簡単な訓練により使いこなせるばかりでなく、比較的短時間に自動造形可能となる。
（２） 切削加工では、部品分割をしない限り複雑な内部形状は加工できない。外部形状でも工具が入らない形状のものは加工できない。しかし、積層造形法では、どんな複雑形状でも、造形可能であり、しかも寸法形状もかなり高い。
（３） 切削加工機は、環境上や使用電力の問題によりオフイス内では使用できない。積層造形機は一部の例外を除いて、切削も発生せずまた騒音も発生しないので、オフイス環境で十分使用できる。工作機械に比較すると機械は小型であり、デスクトップ機も存在する。
（４） 設計変更や精度不足に対しても、ＣＡＤデータを修正しさえすれば、造形品の変更や修正が極めて容易である。実際の造形自体が切削加工に比較して非常に簡単であるために、修正後の再造形が容易でありこの利点が生かされている。 Non-Patent Document 1 is a layered product that creates a three-dimensional structure by stacking and joining thin layered materials required from three-dimensional CAD data. It has been developed and developed mainly. After that, methods other than the optical modeling method as shown in FIG. 2 have been developed to become a layered modeling method. The feature of this additive manufacturing method is
(1) Cutting requires skill in selecting machining conditions and creating CAD / CAM data, and requires a considerable amount of machining, including changing the workpiece. However, in additive manufacturing, as long as three-dimensional CAD data exists, many operations are automated, and not only can they be used by simple training, but also automatic modeling can be performed in a relatively short time.
(2) In cutting, complicated internal shapes cannot be processed unless parts are divided. An external shape that does not contain a tool cannot be machined. However, in the additive manufacturing method, any complicated shape can be formed, and the dimensional shape is quite high.
(3) Cutting machines cannot be used in offices due to environmental and power consumption problems. With a few exceptions, additive manufacturing machines do not generate cutting or noise and can be used in an office environment. Compared to machine tools, the machines are smaller and there are desktop machines.
(4) Even for design changes and insufficient accuracy, it is extremely easy to change or modify a modeled product as long as the CAD data is corrected. Since the actual modeling itself is very simple as compared with the cutting process, remodeling after correction is easy, and this advantage is utilized.

非特許文献２は、積層加工法で生じるカール（curl,そり）のメカニズムを図３で示すように図解で説明している。カールとは、液体樹脂の体積の収縮にともなって発生する不均等な応力が原因で生じるひずみである。積層状にピコドット粒子で射出するインクジェットでも同じ現象が見られる。液体樹脂は、重合反応を起こして、硬化すると体積の収縮を起こす。最上層の液体樹脂を、すでに硬化しているすぐ下の層よりも大きく硬化させると、下に支えのないカンチバレーの第１層目ができる。２層目を、すでに硬化収縮している１層目の上に硬化させると、まず１層目の樹脂に接着する。接着後も２層目の樹脂の体積の収縮が続くので、下の１層目との間に不均一な応力が発生して曲げモーメントが生じる。しかし、何層か積層を続けると自己補正効果が現れ、カールが無くなり平坦になる。 Non-Patent Document 2 illustrates the curl mechanism generated by the laminating method as illustrated in FIG. The curl is a strain caused by uneven stress generated as the volume of the liquid resin shrinks. The same phenomenon can be seen in an inkjet ejected with picodot particles in a laminated form. The liquid resin undergoes a polymerization reaction and causes volume shrinkage when cured. If the uppermost liquid resin is cured to a greater extent than the immediate lower layer, a first cantilevered first layer that is unsupported is formed. When the second layer is cured on the first layer that has already been cured and shrunk, it first adheres to the first layer resin. Since the volume of the resin of the second layer continues to shrink even after bonding, non-uniform stress is generated between the lower layer and the bending moment. However, if several layers are continued, a self-correction effect appears, and the curl disappears and becomes flat.

非特許文献３は、三次元位置を非接触で計測する画像計測技術がまとめられている。１９７０年代に人体の形状計測にモアレトポグラフィが誕生した。しかしながら、このモアレトポグラフィの測定精度は数ｍｍ程度であり、高速で三次元計測できる技術の登場が望まれていた。非接触三次元デジタイザは、ＣＣＤカメラで測定物を撮影し、その三次元空間上の一点一点の位置を三角測量の理論により計算し、測定物の三次元形状の寸法を決定する。三次元非接触デジタイザは、非接触式三次元測定機で計測するよりも測定時間が短
く、測定密度も非常に高く人体のような曲面測定に優れ、面データであるポリゴンデータで出力されるので、ＣＡＤデータにも変換できる。 Non-Patent Document 3 summarizes image measurement techniques for measuring a three-dimensional position in a non-contact manner. Moire topography was born in the 1970s for measuring the shape of the human body. However, the measurement accuracy of this moire topography is about several millimeters, and the advent of a technique capable of three-dimensional measurement at high speed has been desired. The non-contact three-dimensional digitizer photographs a measurement object with a CCD camera, calculates the position of each point in the three-dimensional space based on the theory of triangulation, and determines the dimension of the three-dimensional shape of the measurement object. The 3D non-contact digitizer is shorter in measurement time than the non-contact 3D measuring machine, has a very high measurement density and is excellent for curved surface measurement like a human body, and is output as polygon data as surface data. It can also be converted into CAD data.

非特許文献４は、アクリレートの皮膚刺激性の評価法が書かれている。歯科用接着樹脂としても使われるＵＶ硬化樹脂にアクリレートがある。このアクリレートの皮膚刺激性の評価法として用いられているのは白ウサギの病変の評価方法である。紅斑の状態と浮腫の大きさを０〜４の５段階で評価し、２つの合計値で示すＤｒａｉｚｅ法が一般的に用いられる。この値をP.I.I.(Primary Irritation Index:皮膚一次刺激性指数）とよび０〜８の指数で表している。アクリレートの分子量とP.I.I.との関係を図４に示す。皮膚刺激性は個人差もあり、最近では２以下を目標値とする企業が増えている。 Non-Patent Document 4 describes a method for evaluating the skin irritation of acrylate. An acrylate is a UV curable resin that is also used as a dental adhesive resin. A method for evaluating lesions in white rabbits is used as a method for evaluating the skin irritation of this acrylate. The Draize method is generally used in which the state of erythema and the size of edema are evaluated on a scale of 0 to 4 and indicated by two total values. This value is expressed as P.I.I. (Primary Irritation Index) and an index of 0-8. The relationship between the molecular weight of acrylate and P.I.I. is shown in FIG. Skin irritation varies from individual to individual, and recently, an increasing number of companies have a target value of 2 or less.

This growth is closely related to the health of the whole body, and abnormalities and troubles in the body can appear as nail diseases.

In P002, a part corresponding to the growth of the nail is predicted from the measurement data, and the optimum shape is determined by the finite element method.
In P003, keratin (protein), which is a component of the nail, is laminated on the affected area of the nail from the ink jet injection port.
In P004, a nail correction tool is attached to the toenail or fingernail.
P005 causes the keratin (protein) to be laminated again on the nail site if there is a possibility that an unforeseen situation may occur due to inhibition of nail growth depending on the health condition of the patient.

In the present invention, when the adhesion between the original nail and the newly produced laminated keratin is weak, an acrylate UV cured layer can be added based on the measured three-dimensional data. The lower part of FIG. 1 of the present invention is a nail corrector 112 laminated or attached to the curled nail corrector 111.
The present invention can predict the growth according to the growth of the nail based on the three-dimensional data obtained by detecting the growth of the nail on the living body with the CMOS sensor, and can determine the optimum shape by the finite element method. Therefore, its industrial value is extremely high.
