Abstract
Description
本発明は、損失した天然歯の代用品として使用される人工歯および義歯に関するものである。 The present invention relates to artificial teeth and dentures used as substitutes for lost natural teeth.
人工歯は、損失した天然歯の代用品として、インプラントの上部構造体として使用されたり、義歯床に設けられて義歯として使用されたりしている。
人工歯は、天然歯の残存歯と違和感が無いように色合せされる。また、無歯顎者である場合には、一般的な天然歯が有する色彩や明度のものが選択される。このとき、色相や明度、彩度の基準となるシェードガイドと称される色見本が用いられる。
Artificial teeth are used as superstructures of implants as substitutes for lost natural teeth, or are provided on denture bases and used as dentures.
The artificial teeth are color-matched so that there is no sense of incongruity with the remaining natural teeth. In addition, in the case of an edentulous person, one having a color or brightness that a general natural tooth has is selected. At this time, a color sample called a shade guide is used as a reference for hue, brightness, and saturation.
シェードガイドでは、人工歯の色を、赤味がかった茶色系であるＡ系として５種類、赤味がかった黄色系であるＢ系として４種類、灰色系であるＣ系として４種類、赤味がかった灰色系であるＤ系として３種類に分類されている。
このようなシェードガイドによる色選択に関し、特許文献１に記載されたものが知られている。
For shade guides, artificial teeth are available in 5 types for reddish brown A type, 4 types for reddish yellow B type, 4 types for gray C type, reddish It is classified into three types as D type which is a grayish type.
Regarding color selection by such a shade guide, one described in Patent Document 1 is known.
特許文献１に記載の「歯の色を判定する方法および該方法を実施するためのシェードガイド」は、Ａ系色の色見本の中で歯に最も明るさが近い色の色見本を選択し（工程１）、次に、色の明るさを指標にして色見本を明るさの高低順に並べたときの、最も明るい側から３つの色見本毎にグループ分けしたグループのうちの、工程１で選択した色見本が存在するグループの中での評価対象歯に最も明るさが近い色の色見本を選択する（工程２）というものである。 The “method for determining the color of a tooth and the shade guide for carrying out the method” described in Patent Document 1 selects a color sample of the color closest to the tooth among the color samples of the A system color. (Step 1) Next, in Step 1 among the groups grouped by three color samples from the brightest side when the color samples are arranged in order of brightness, using the brightness of the color as an index. The color sample having the color closest to the evaluation target tooth in the group in which the selected color sample exists is selected (step 2).
人工歯は、シェードガイドによる色選択により、一般的な歯牙の色を模して人工歯の色が選択されるため、人工歯の色は一定以上の黄色みを有するランクが選択される。しかし、人工歯は、天然歯と異なり自浄作用に乏しいため、歯垢や、付着物による着色により汚れやすい。
また、人工歯は、歯垢が付着したり、着色されたりしても、黄色みを帯びているため、視認しにくい。人工歯への歯垢の付着や着色が視認できれば、装着者に歯垢や着色を除去させるような動機付けさせることができる。
For artificial teeth, the color of an artificial tooth is selected by imitating the color of a general tooth by selecting a color with a shade guide. Therefore, the rank of the artificial tooth having a certain yellow or higher color is selected. However, artificial teeth, unlike natural teeth, have a poor self-cleaning action, and thus are prone to staining due to plaque and coloring due to adhering substances.
Further, even if plaque is attached or colored, the artificial tooth is yellowish and thus difficult to visually recognize. If the adhesion and coloring of the plaque on the artificial tooth can be visually recognized, the wearer can be motivated to remove the plaque and coloring.
そこで本発明は、歯垢や着色が容易に発見できることにより、口腔内の衛生環境を向上させることができる人工歯および義歯を提供することを目的とする。 Therefore, an object of the present invention is to provide an artificial tooth and a denture that can improve the hygiene environment in the oral cavity by easily discovering plaque and coloring.
本発明の人工歯は、シェードガイドにて分類されるＢ１より表面の明度が高いことを特徴とする。
本発明の人工歯によれば、表面が、シェードガイドにて分類される明度が最も高いＢ１より、更に明度が高いため、少しの歯垢や着色でも容易に発見できる。
The artificial tooth according to the present invention is characterized in that the surface brightness is higher than B1 classified by the shade guide.
According to the artificial tooth of the present invention, the surface is further brighter than B1 having the highest lightness classified by the shade guide, so that even a little plaque or coloring can be easily found.
前記表面が鏡面加工されていると、歯垢を付着し難くすることができる。
また、前記表面が抗菌加工されていると、歯垢の原因になる細菌の付着を抑止することができる。
When the surface is mirror-finished, plaque can be made difficult to adhere.
In addition, when the surface is antibacterial, it is possible to suppress the adhesion of bacteria that cause dental plaque.
本発明は、表面の明度がＢ１より明るいため、少しの歯垢や着色でも容易に発見できるので、歯垢や着色が容易に発見できることにより、口腔内の衛生環境を向上させることができる。 In the present invention, since the lightness of the surface is brighter than B1, even a small amount of plaque and coloring can be easily found, so that the plaque and coloring can be easily found, thereby improving the oral hygiene environment.
本発明の実施の形態に係る人工歯を用いた義歯を図面に基づいて説明する。
図１に示す義歯１０は、上顎用の総義歯である。義歯１０は、上顎の天然歯を模した人工歯１１と、人工歯１１を支持するアーチ状の歯肉部１２ａおよび口蓋部１２ｂを有する義歯床１２とを備えている。
図２に示す義歯２０は、下顎用の総義歯である。義歯２０は、下顎の天然歯を模した人工歯２１と、人工歯２１を支持するアーチ状の歯肉部２２ａを有する義歯床２２とを備えている。
A denture using an artificial tooth according to an embodiment of the present invention will be described with reference to the drawings.
The denture 10 shown in FIG. 1 is an upper denture complete denture. The denture 10 includes an artificial tooth 11 simulating an upper natural tooth and a denture base 12 having an arch-shaped gingival portion 12 a and a palate portion 12 b that support the artificial tooth 11.
The denture 20 shown in FIG. 2 is a complete denture for the lower jaw. The denture 20 includes an artificial tooth 21 that imitates the natural teeth of the lower jaw and a denture base 22 having an arch-shaped gingival portion 22 a that supports the artificial tooth 21.
人工歯１１と人工歯２１とは、表面が、シェードガイドにて分類される明度が最も高いＢ１より高い明度を有している。
ここで、シェードガイドについて説明する。図３に示すシェードガイド１００は、ＶＩＴＡ社製のＶＩＴＡ Ｃｌａｓｓｉｃａｌが使用できる。シェードガイド１００は、色見本としての見本歯１０１がハンドル部１０２に取り付けられた状態で、ケース１０３に明度順に収納されている。
ハンドル部１０２の先端部には、タグ部１０２ａが形成され、色見本の明度を示す記号が付与されている。
The artificial tooth 11 and the artificial tooth 21 have lightness higher than that of B1, which has the highest lightness classified by the shade guide.
Here, the shade guide will be described. The shade guide 100 shown in FIG. 3 can use VITA Classic made by VITA. The shade guide 100 is housed in the case 103 in the order of lightness, with the sample teeth 101 as color samples attached to the handle portion 102.
A tag portion 102a is formed at the distal end portion of the handle portion 102, and a symbol indicating the brightness of the color sample is given.
人工歯の色は、５種類のＡ系（Ａ１〜Ａ３，Ａ３．５，Ａ４）、４種類のＢ系（Ｂ１〜Ｂ４）、４種類のＣ系（Ｃ１〜Ｃ４）、および３種類のＤ系（Ｄ２〜Ｄ４）に分類されている。タグ部１０２ａには、記号として、人工歯の色を示すＡ１〜Ａ３，Ａ３．５，Ａ４・・・などが刻印されている。
シェードガイド１００では、明度が最も高い（明るい）「Ｂ１」から、最も低い（暗い）「Ｃ４」までが、右側から順に左側へ配列されている。
このようなシェードガイド１００は、歯科医師または歯科技工士が、ケース１０３からハンドル部１０２を持って見本歯１０１を取り出して、見本歯１０１を色見本として、装着者に合う色を選択する。
人工歯１１および人工歯２１は、シェードガイド１００にて分類される明度が最も高いＢ１より高い明度を有しているため、際立って色の白い歯ということができる。
The colors of the artificial teeth are 5 types A (A1 to A3, A3.5, A4), 4 types B (B1 to B4), 4 types C (C1 to C4), and 3 types D. It is classified into the system (D2 to D4). A1 to A3, A3.5, A4, etc. indicating the color of the artificial tooth are engraved on the tag portion 102a as symbols.
In the shade guide 100, “B1” having the highest brightness (bright) to “C4” having the lowest brightness (dark) are arranged in order from the right side to the left side.
In such a shade guide 100, a dentist or a dental technician takes out the sample tooth 101 from the case 103 by holding the handle portion 102, and uses the sample tooth 101 as a color sample to select a color suitable for the wearer.
Since the artificial tooth 11 and the artificial tooth 21 have a lightness higher than the highest lightness B1 classified by the shade guide 100, it can be said that the tooth is markedly white.
人工歯１１と人工歯２１の表面が、「Ｂ１」の見本歯１０１より高い明度を有している否かは、シェードガイドを用いた視感比色法により判定することができる。また、シェードガイドの「Ｂ１」を色彩計で測定したときの明度と、人工歯１１と人工歯２１の表面を色彩計で測定したときの明度とを比較することで判定することができる。 Whether the surfaces of the artificial tooth 11 and the artificial tooth 21 have higher brightness than the sample tooth 101 of “B1” can be determined by a visual colorimetric method using a shade guide. Moreover, it can determine by comparing the brightness when “B1” of the shade guide is measured with a colorimeter and the brightness when the surfaces of the artificial teeth 11 and the artificial teeth 21 are measured with a colorimeter.
シェードガイドのそれぞれの色見本では、見本歯１０１の歯冠部と歯頸部とで明度が異なる。歯冠部では明度が高く、歯頸部では歯冠部と比較して明度が低い。それは、装着者に義歯１０，２０として装着したときに、人工歯１１，２１をより自然に見せるためである。従って、歯冠部は明度が高く（明るく）、歯頸部は明度が低く（暗く）形成されている。人工歯１１と人工歯２１は、シェードガイドの対応するそれぞれの部位で明度が高い。 In each color sample of the shade guide, the brightness differs between the crown portion and the tooth neck portion of the sample tooth 101. The lightness is high in the crown portion, and the lightness is low in the tooth neck portion as compared with the crown portion. This is to make the artificial teeth 11 and 21 appear more natural when mounted on the wearer as the dentures 10 and 20. Therefore, the crown part is formed with high brightness (bright), and the tooth neck part is formed with low brightness (dark). The artificial tooth 11 and the artificial tooth 21 have high brightness at the corresponding portions of the shade guide.
この人工歯１１と人工歯２１とは、陶歯、レジン歯、ハイブリッドレジン歯、ジルコニア製の人工歯などとすることができる。
人工歯１１と人工歯２１を、陶歯とするときには、「Ｂ１」より高い明度に着色された陶材粉末泥を印象型または金型に充填して成形し、乾燥させた後に、焼成することにより、陶歯が形成できる。また、人工歯の形状に成形し、焼成した後に、着色してもよい。
The artificial teeth 11 and the artificial teeth 21 can be porcelain teeth, resin teeth, hybrid resin teeth, zirconia artificial teeth, and the like.
When the artificial tooth 11 and the artificial tooth 21 are porcelain teeth, the impression powder or mold is filled with porcelain powder mud colored with a higher brightness than “B1”, dried, and then fired. Thus, porcelain teeth can be formed. Further, it may be colored after being formed into an artificial tooth shape and fired.
また、人工歯１１と人工歯２１をレジン歯またはハイブリッドレジン歯とするときには、例えば、「Ｂ１」より高い明度を有するレジンを印象型または金型に充填して成形し、硬化させることによりレジン歯を形成することができる。また、人工歯の形状に成形し、硬化させた後に、着色してもよい。
人工歯１１と人工歯２１をジルコニア製の人工歯とするときには、「Ｂ１」より高い明度のジルコニアを切削して成形し、焼成することでジルコニア製の人工歯とすることができる。また、ジルコニア製の人工歯は、焼成してから切削して成形してもよい。更に、ジルコニア製の人工歯は、必要に応じて着色してもよい。
Further, when the artificial tooth 11 and the artificial tooth 21 are resin teeth or hybrid resin teeth, for example, a resin having a lightness higher than “B1” is filled in an impression mold or a mold, and then molded and cured to form a resin tooth. Can be formed. Further, it may be colored after being formed into a shape of an artificial tooth and cured.
When the artificial teeth 11 and the artificial teeth 21 are made of zirconia, the zirconia artificial teeth can be made by cutting and forming zirconia having a lightness higher than “B1” and firing. Further, the artificial teeth made of zirconia may be cut and molded after firing. Furthermore, the artificial teeth made of zirconia may be colored as necessary.
人工歯１１と人工歯２１とは、シェードガイドにて分類される最も明度が高い「Ｂ１」より更に明度が高いので、人工歯１１および人工歯２１に付着した少しの歯垢や着色でも容易に発見できる。従って、人工歯１１および人工歯２１は、歯垢の付着や着色が用に視認できることにより、歯垢や着色を除去しようとする動機付けを装着者に促すことができるので、口腔内の衛生環境を向上させることができる。 Since the artificial tooth 11 and the artificial tooth 21 have higher brightness than the highest brightness “B1” classified by the shade guide, even a little plaque or coloring attached to the artificial tooth 11 and the artificial tooth 21 can be easily obtained. Can be found. Therefore, the artificial tooth 11 and the artificial tooth 21 can prompt the wearer to motivate the wearer to remove plaque and coloring by visually confirming the adhesion and coloring of plaque. Can be improved.
人工歯１１と人工歯２１とは、その表面が、鏡面加工されている。特に、義歯床１２，２２から露出した人工歯１１と人工歯２１の表面が、鏡面加工されていることが望ましい。鏡面加工は、コーティング加工により行うことができる。コーティング加工は、ガラスコーティングまたはコーティング用樹脂材によるコーティングとすることができる。また、鏡面加工は、人工歯１１，２１を形成する材料に、人工歯１１，２１の明度に影響しない程度のガラスビーズなどの粒子を含有させ、研磨によって鏡面加工をしやすくして、その後の研磨によって鏡面を得るようにしてもよい。人工歯１１と人工歯２１の表面が鏡面加工されていることで、歯垢を付着し難くすることができる。 The surfaces of the artificial teeth 11 and the artificial teeth 21 are mirror-finished. In particular, it is desirable that the surfaces of the artificial teeth 11 and the artificial teeth 21 exposed from the denture bases 12 and 22 are mirror-finished. The mirror finish can be performed by coating. The coating process can be a glass coating or a coating with a resin material for coating. In addition, the mirror surface processing is performed by adding particles such as glass beads that do not affect the brightness of the artificial teeth 11 and 21 to the material forming the artificial teeth 11 and 21 and making the mirror surface processing easy by polishing. A mirror surface may be obtained by polishing. Since the surfaces of the artificial teeth 11 and the artificial teeth 21 are mirror-finished, it is possible to make it difficult to adhere plaque.
また、人工歯１１と人工歯２１とは、その表面が、抗菌加工されている。抗菌加工としては、抗菌コートが適用できる。抗菌コートは、例えば、緑茶ポリフェノールやグレープフルーツ種子抽出物などの天然由来のもの、酸化チタンなどの光触媒や、銀イオン、銅イオン、亜鉛イオンなどの金属イオンなどの無機物のものをコーティング材に含有させたものが使用できる。 Further, the surfaces of the artificial teeth 11 and the artificial teeth 21 are antibacterial processed. An antibacterial coating can be applied as an antibacterial process. The antibacterial coating contains, for example, naturally-derived materials such as green tea polyphenols and grapefruit seed extracts, photocatalysts such as titanium oxide, and inorganic materials such as metal ions such as silver ions, copper ions, and zinc ions. Can be used.
また、抗菌加工としては、人工歯１１，２１を形成する材料に、添加用抗菌剤を含有させることもできる。添加用抗菌剤としては、例えば、銀、銅、亜鉛などの無機物系抗菌剤や、ニトリル誘導体、イミダゾール誘導体、トリアジン誘導体、フェノールエステル誘導体、ピロール誘導体などの有機系抗菌剤を用いることができる。
人工歯１１と人工歯２１との表面が抗菌加工されていることで、歯垢の原因になる細菌の付着を抑止することができる。
Moreover, as an antibacterial process, the material which forms the artificial teeth 11 and 21 can also contain the antibacterial agent for addition. As the antibacterial agent for addition, for example, inorganic antibacterial agents such as silver, copper and zinc, and organic antibacterial agents such as nitrile derivatives, imidazole derivatives, triazine derivatives, phenol ester derivatives and pyrrole derivatives can be used.
Since the surfaces of the artificial teeth 11 and the artificial teeth 21 are antibacterial processed, adhesion of bacteria that cause plaque can be suppressed.
また、人工歯１１，２１は、義歯床１２，２２への接合部分に、義歯床１２，２２との接合強度を向上させるための加工が施されている。
人工歯１１，２１の表面が鏡面加工されていると、義歯床１２，２２から露出した部分は歯垢が付着し難くなるが、義歯床１２，２２と接触する部分は接合強度が低下する。
Further, the artificial teeth 11 and 21 are subjected to processing for improving the joint strength with the denture bases 12 and 22 at the joint portions to the denture bases 12 and 22.
When the surfaces of the artificial teeth 11 and 21 are mirror-finished, the portions exposed from the denture bases 12 and 22 are difficult to adhere to the plaque, but the joint strength is reduced at the portions contacting the denture bases 12 and 22.
そこで、上顎の義歯１０を例に説明すると、図４に示すように、人工歯１１の接合部分１１ａへの加工としては、例えば、機械的に接合部分１１ａの表面を梨地とするサンドブラストや、化学的に梨地とするレジンプライマーを施すことができる。人工歯１１，２１の接合部分の表面を梨地とすることで、接触面積が増加するため、人工歯１１，２１と義歯床１２，２２の接合強度を増加させることができる。 Therefore, the maxillary denture 10 will be described as an example. As shown in FIG. 4, the artificial tooth 11 may be processed into the joint portion 11a by, for example, sandblasting with the surface of the joint portion 11a as a matte surface, Resin primer can be applied. Since the contact area is increased by using the surface of the joint portion of the artificial teeth 11 and 21 as the matte surface, the joint strength between the artificial teeth 11 and 21 and the denture bases 12 and 22 can be increased.
また、人工歯１１，２１の接合部分に凸部や凹部を設け、義歯床１２，２２を成形すると、人工歯１１，２１の凸部に嵌る凹部や、人工歯１１，２１の凹部に嵌る凸部が、アンダーカットとして義歯床１２，２２に成形されるため、より一層の接合強度を確保することができる。
また、人工歯１１，２１と義歯床１２，２２とを一体成形する以外に、義歯床１２，２２に人工歯１１，２１を接着剤によって貼り付けるようにしてもよい。
Further, when a convex portion or a concave portion is provided at the joint portion of the artificial teeth 11 and 21, and the denture bases 12 and 22 are formed, the concave portion that fits into the convex portion of the artificial teeth 11 or 21, or the convex portion that fits into the concave portion of the artificial teeth 11 and 21. Since the part is formed on the denture bases 12 and 22 as an undercut, further bonding strength can be ensured.
In addition to integrally molding the artificial teeth 11 and 21 and the denture bases 12 and 22, the artificial teeth 11 and 21 may be attached to the denture bases 12 and 22 with an adhesive.
義歯床１２，２２は、人工歯１１，２１の白さに合わせて、通常の歯肉色より明るくすることにより、白い人工歯１１，２１との違和感を抑制するのが望ましい。
また、義歯床１２，２２においても、通常は、ピンク色系の歯肉色であるが、歯肉色の明度を上げたり、人工歯１１，２１の色に合わせて白くしたりしてもよい。そうすることで、装着者は、義歯床１２，２２に付着した歯垢や、磨き残しなどが一目瞭然で認識できる。
Desirably, the denture bases 12 and 22 are made lighter than the normal gingival color in accordance with the whiteness of the artificial teeth 11 and 21, thereby suppressing a sense of discomfort with the white artificial teeth 11 and 21.
Further, the denture bases 12 and 22 are usually pink gingival color, but the brightness of the gingival color may be increased or whitened in accordance with the colors of the artificial teeth 11 and 21. By doing so, the wearer can recognize at a glance the plaque attached to the denture bases 12 and 22 and the unpolished material.
本実施の形態では、人工歯を総義歯の歯牙として用いた例を説明したが、部分義歯でもよい。また、人工歯は、歯冠修復やインプラントの上部構造など、歯牙の代わりとなるものであれば、本発明を適用することができる。 In this embodiment, the example in which the artificial tooth is used as the tooth of the complete denture has been described, but a partial denture may be used. In addition, the present invention can be applied to any artificial tooth as long as it is a substitute for a tooth such as a crown restoration or an upper structure of an implant.
本発明は、歯垢や着色が容易に発見できることにより、口腔内の衛生環境を向上させることができるので、損失した天然歯の代用品として使用される人工歯および義歯に好適である。 The present invention is suitable for artificial teeth and dentures used as a substitute for lost natural teeth because it can improve the hygiene environment in the oral cavity by easily discovering plaque and coloring.
