Abstract
Description
以下、本発明について説明する。ここでは分かり易さのため、図面に付した参照符号を括弧書きで併せて記載するが、本発明はこれに限定されるものではない。
本形態で連結部12は、人工歯根40の端部に固定される固定部12aと、該固定部12aに連続する首部12bと、を有している。そして球状部11は、首部12bの端部のうち、固定部12aとは反対側に連続して配置されている。
これら図からわかるように凹要素20は、本体21及びOリング22を有して構成されている。
開口部21bは、上記した凸要素10の球状部11及び連結部12が通ることができる大きさとされ、中空部21cはその内側に球状部11が収納されるように形成される。なお後述するように球状部11が中空部21cに収納された姿勢で、球状部11と底21aとの間には間隙が形成される。
また、本体21の外面には、レジンとの接合力を高めるための窪み21dが形成されていることが好ましい(図2参照)。
スリット21fの幅(図1の紙面左右方向の幅)は特に限定されることなく水の排出性能や凹要素20の強度等の観点から適宜調節することができる。
また、上記したようにOリング22の線材の線径は、溝21eの幅と概ね同じであり、溝21eの深さよりも大きい。
また、図3(b)からわかるように、スリット21fが設けられた部位については、本体21の筒状である壁面が除去され(切り欠かれ)、中空部21cから溝21eを通じて外部に連通している。
このような嵌合は、球状部11を凹要素20の開口部21b側から差し込み、少し強い力を加えることによりOリング22を弾性変形させつつ球状部11を中空部21c内に挿入することにより行うことができる。
凸要素10は、顎骨50に植立された人工歯根40に固定されるものであり、凹要素20は、義歯32を具備する有床義歯30の樹脂からなる義歯床31のうち、凸要素10に対応した位置に配置される。凹要素20の義歯床31への配置は例えば、有床義歯30の成形時または成形後に、義歯床31に凹部31aを形成してここに凹要素20が挿入されて固定される。そして、上記説明したように凸要素10と凹要素20とを嵌め合わせて有床義歯30を口腔内に配置する。さらに詳しくは次の通りである。
一方、義歯床31のうち、口腔粘膜に対応する面に、口腔内に埋入された人工歯根40の位置を写し取る。写し取る方法は特に限定されず、例えば人工歯根40に固定された凸要素10の球状部11の頂点にマーキングをし義歯床31を押し当てて位置を写し取ることができる。また、柔らかな印象材を義歯床31の口腔内面側に塗布して口腔内に当てることで印象材面に球状部11の位置を転写することもできる。
従って、空間Vaの圧縮により、ここに浸入した液体がアタッチメント設計時の弾性変形を妨げ、維持歯である人工歯根に大きな負担がかかることを防止できる。そして、高まった圧力によりOリングが脱落してしまう問題を解決することが可能となった。
