PROBLEM TO BE SOLVED: To solve problems in an oral cavity, for example, because of contact of hard tissues of teeth and mastication, a form of teeth is easily changed, and due to wear of teeth, many gaps between teeth, and difficulty of washing teeth, and adhesion of food scraps adhered to gaps between teeth, an energy source of growth of bacteria in a mouth is generated, resulting in dental caries and periodontal disease, and if one loses a tooth on a jaw, an opposite tooth is not used in daily life, so that extrusion of a tooth occurs, and movement of adjacent teeth to a side where a tooth is lost, resulting in a harmful effect in a mastication performance and a periodontal tissue, so that, a meal mouth piece for efficiently reducing dental caries and coloring for protecting teeth, or preventing abnormal movement of teeth, preventing press-fit of the food scraps, holding a tooth row and articulation, and protecting interdental papilla.SOLUTION: A meal mouth piece which tightly contacts ones teeth and gum, and which is formed of a soft material and a hard material, is provided, and an outside of an occlusal surface of a molar part is formed of a hard material, the meal mouth piece is attached to ones jaw for protecting ones teeth.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】口腔の中、歯は硬組織同士が接触、咀嚼のため、とても形態が変化しやく、歯の摩耗、歯の間に隙間が多く、掃除しにくく、飲食による、歯の隙間に食べ物の滓がくっつかれて、口の中の菌の生息するエネルギー源となって、虫歯や歯周病など引き起こるである。顎に歯が失った場合、反対側の歯は日常使用しないので、歯の挺出を引き起こし、隣在歯の失った歯側への移動を生じ、咀嚼能率や歯周組織にも悪影響を与える。本発明は、虫歯、着色などを効果的に減少し、歯を守ることを目的とするものである、又は歯の不正移動の防止、食片圧入の防止、歯列及び咬合の保持、歯間乳頭の保護などを目的とするものである。【解決手段】歯と歯肉に密着し、軟質材料と硬質材料で作られ、臼歯部の咬合面の外側は硬質材料でつくられたミールマウスピースを顎に付けて、歯をまもる。【選択図】図1
