本発明は、生体の骨組織内に埋設して用いる人工歯根の
改良に係わり、更に詳しくは金属製人工歯根表面を歯肉

ものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the improvement of an artificial tooth root that is used by being embedded in the bone tissue of a living body, and more specifically, to match the surface of a metal artificial tooth root with the color tone of the gums. It concerns an artificial tooth root colored like this.
（従来の、技術）
従来から、軽量で耐食性があり、且つ生体組織と親和性

された後、図示のように口腔内の生体骨組織１や人工歯
根膜２内に該人工歯根根部７を埋設されるが、埋設後に
おいても人工歯４を装着する人工歯根頭部８は歯肉３の
上に突出しており、人工歯４を装着した場合には。(Conventional Technology) Artificial tooth roots made of materials such as Ti and Zr that are lightweight, corrosion resistant, and have excellent affinity with living tissue have been known. After the surface of the artificial tooth root made of Ti, Zr, etc. is subjected to treatments such as polishing, pickling, blasting, and thermal spraying, the artificial tooth root is placed in the living bone tissue 1 in the oral cavity or the artificial periodontal ligament 2 as shown in the figure. Although the tooth root 7 is buried, the artificial tooth root head 8 on which the artificial tooth 4 is attached protrudes above the gum 3 even after the implantation, and when the artificial tooth 4 is attached.
人工歯根頭部８は人工歯４によってカバーされるが１人
工歯根類部５は露出状態となり、また、その頚部直下の
上部人工歯根根部６は歯肉３によってカバーされるもの
の歯肉３の厚みが薄いので。The artificial tooth root head 8 is covered by the artificial tooth 4, but the artificial tooth root part 5 is exposed, and the upper artificial tooth root part 6 directly below the neck is covered by the gingiva 3, but the thickness of the gingiva 3 is thin. So.
半透視されるピンク色の歯肉３の色調と下地の上記根部
５の色調とが重なり合って視認されるものとなっている
。The semi-transparent pink color tone of the gums 3 and the color tone of the base root 5 are visually recognized as overlapping.

となり、外観上着者に違和感や病的感を与えるという問
題点があり、患者もこの理由のために口腔内を大きく露
呈することに恥らいや劣等感を抱く所となった。(Problems to be Solved by the Invention) By the way, the artificial tooth root made of Ti or the like has a so-called dark white-gray to gray color tone unique to metals.
The color tone is different from that of the gums or teeth, and especially in the cervical region 5, the color is a dark white-gray that is incongruous with the pink color of the gums 3.
The gray metallic color is exposed as it is, and in the upper artificial-like root 6 covered with thin gum 3, pink tone and white-gray to gray tone are mixed, resulting in a blue-black, sunken, sickly tone. However, there is a problem in that the outer appearance gives the wearer a sense of discomfort or morbidity, and for this reason, patients also feel shame and inferiority in having their oral cavity exposed to a large extent.
そこで本発明は、上記従来の問題点の解消のため、Ｔｉ
などの金属製人工歯根の表面を歯肉の色調にマツチさせ

へ埋設したのちにおいても。Therefore, the present invention aims to solve the above-mentioned conventional problems.
Even after the surface of a metal artificial tooth root is colored to match the color tone of the gums, the artificial tooth root is embedded in living bone tissue.
外観上歯肉の色調と異和感を抱かせることなく。It does not look different from the color of your gums.
むしろ患者に対しては安堵感を与えるとともに、該着色
薄膜の生成によって歯肉と該金属製人工歯根との密着性
をも改善させた人工歯根を提供することを目的としてい
る。Rather, the purpose is to provide an artificial tooth root that not only gives the patient a sense of relief, but also improves the adhesion between the gingiva and the metal artificial tooth root through the production of the colored thin film.

An artificial tooth root is manufactured from a material made of a single metal selected from a and Nb or an alloy thereof, and its surface is colored by anodizing or nitriding to match the color tone of the gums.
（作用）
本発明ではそれ自体は暗い白灰色〜灰色の色調を有する

金色は上側のピンク色に輝きを与える色感を添えるので
、この重合色に病的な色感を生み出すことがない。(Function) In the present invention, although the artificial tooth root itself is made of a single metal or an alloy having a dark white-gray to gray tone,
The surface is colored with a thin gold film by anodizing or nitriding, so the base color is completely opaquely covered by the gold color on the surface. Therefore,
When this is implanted into a living bone, the neck 5 described above will shine gold, and the upper artificial tooth root 6 will appear as the underlying color of the pink gums 3, but there will be a difference between pink and gold. There is no unnatural color relationship in the overlapping of the top and bottom, and the gold color of the base adds a color sense that gives shine to the pink color above, so this overlapping color does not create a sickly color sense.
他方、酸化薄膜もしくは窒化薄膜の形成は、僅かながら
も歯根表面を粗面化する所となるから接触組織との接触
面積の増大となり、この意から密着性の幾ばくかの改善
がみられる。On the other hand, the formation of a thin oxide film or a thin nitride film roughens the tooth root surface, albeit slightly, and increases the contact area with the contact tissue, which results in some improvement in adhesion.
（実施例） 以下、本発明の実施例を記載する。(Example) Examples of the present invention will be described below.

なる。An artificial tooth root made from a single metal selected from Ta and Nb or an alloy thereof is colored gold by anodizing or nitriding to match the color tone of living gums, so it is different from conventional metal roots. It eliminates the appearance problems of artificial tooth roots, that is, the discomfort and morbidity caused by the color tone, which is different from that of the gums, and increases the surface area due to the roughening caused by the formation of this colored thin film. This increase in surface area has the effect of improving the adhesion between the gingiva and the artificial tooth root surface accordingly.
