PROBLEM TO BE SOLVED: To provide a tooth extraction tool which can twist a tooth without being affected by or affecting adjacent teeth during tool extraction.SOLUTION: A tooth extraction tool is formed of a screw part to be screwed into a tooth and a handle part. A rod-like body, which is extremely flexible and can be bent, is provided at an apex of the handle part. With the handle part, the screw part is screwed into a hole in a center part of the tooth, then when the screw part sufficiently bites into the tooth, the tooth is extracted with the handle part. In doing so, since a tooth root is twisted and floats from an alveolar bone, tooth extraction is relatively easy and safe. Also, because force for tooth extraction is applied to only the tooth to be extracted, tooth extraction is not affected by and does not affect adjacent teeth. If fingers gripping the handle part slip, a user can grip the rod-like body, so that falling of the tooth extraction tool hardly occurs.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】抜歯に当って、隣合う歯に影響されたり影響を与えたりすることもなく、歯を捻ることが出来る抜歯用具を提供する。【解決手段】抜歯用具は歯内にねじ込むためのネジ部とハンドル部とから成り、ハンドル部の頂部に極めて柔軟で屈曲自在な棒状体を備えている。ハンドル部を以てネジ部を歯の中心部の穴にねじ込み、ネジ部が歯にしっかりと食い込んだらハンドル部を以て引き抜くようにする。この際には歯根が捻られて歯槽骨から浮いて来るために抜歯は比較的容易であり且つ安全である。また抜歯を行う歯にのみ抜歯の力が加わるので隣合う歯に影響されたり影響を与えたりすることが少ない。ハンドル部を摘まむ指が滑っても棒状体を掴むので、抜歯用具を取り落とすことが少ない。【選択図】なし
