Description

【０００１】
【発明が属する技術分野】
この発明は、二酸化チタン等の光触媒を用いた歯牙の漂白光照射装置に関するものである。
【０００２】
【従来の技術】
二酸化チタン等の光触媒は特定の波長の紫外線を照射することにより発生する活性酸素やOHラジカルなどは消毒や殺菌に広く使われている塩素や次亜塩素酸、過酸化水素、オゾンなどよりはるかに強い酸化力を持つ。
【０００３】
また、このOHラジカルのエネルギーは有機物を構成する分子中の炭素−炭素結合、炭素−水素結合等の結合エネルギーよりはるかに大きく、このためこれらの結合を簡単に切断して分解することができる。
【０００４】
二酸化チタンのこれらの性質を利用して、二酸化チタンと過酸化水素等の溶液を変色歯牙表面に付着させ、この部分に紫外線を照射させることにより生ずる光触媒作用に基づき歯牙を漂白する方法が提案されている（特開平11−92351号公報）。
【０００５】
この場合の漂白方法は照射される紫外線を導出する光ファイバー束を備えた紫外線照射器を用意し、漂白すべき歯牙には二酸化チタンと過酸化水素等の溶液等の光触媒を含む漂白剤組成物を歯牙に塗布した後、歯牙の塗布部分に光ファイバー束の先端部を近づけて紫外線を照射して光触媒作用による歯牙の漂白を行うものである。
【０００６】
【発明が解決しようとする課題】
しかし、この方法では紫外線を長時間漂白剤組成物の塗布された歯牙に長時間、例えば10分以上照射するのは口腔内の火傷の危険性もあり、不可能である。
【０００７】
そこで、この発明は紫外線による口腔内の火傷の危険性のない歯牙漂白光照射装置を提供することを目的とする。
【０００８】
【課題を解決するための手段】
この発明は、上記実情に鑑み、本願第1発明は紫外線照射器と、該紫外線照射器より照射される紫外線は人体に有害な波長をカットするフィルターを通して導出させる光ファイバー束と、内部に歯牙の差込溝を有し、且つ光伝導体で構成される歯牙の嵌着器と、紫外線遮断材質で構成された上記嵌着器の外側カバーとからなり、上記光ファイバー束の先端部を歯牙の嵌着器外壁に接続させた歯牙漂白光照射装置を提案するものである。
【０００９】
また、本願第2発明では紫外線照射器と、該紫外線照射器より照射される紫外線は人体に有害な波長をカットするフィルターを通して導出させる光ファイバー束と、内部に歯牙の差込溝を有し、且つ光伝導体で構成される歯牙の嵌着器と、紫外線遮断材質で構成された上記嵌着器の外側カバーとからなり、歯牙の差込溝の底部には光触媒を含む漂白剤溶液の貯留袋を設け、貯留袋には放出ノズルを設け、上記貯留袋は上下歯牙の噛合わせ力により圧縮され、内部の溶液を放出ノズルより歯牙に放出させるようにした歯牙の漂白光照射装置を提案するものである。
【００１０】
更に、本願第3発明では紫外線照射器と、該紫外線照射器より照射される紫外線は人体に有害な波長をカットするフィルターを通して導出させる光ファイバー束と、歯牙の嵌着ケース本体と、該ケース本体の蓋体であって、その内面には蓋体を閉じた状態でケース本体に嵌着された歯牙と対向状に光ファイバー束先端部の固定部が設けられたケース本体内に歯牙の嵌着部を設けた歯牙漂白光照射装置を提案するものである。
【００１１】
【発明の実施の形態】
即ち、本願第1発明では二酸化チタンと過酸化水素水等の溶液等の光触媒を含む漂白剤組成物を歯牙に塗布した後、歯牙を差込溝に差し込み、紫外線照射器より紫外線を光ファイバー束を通して嵌着器に送り込み、該嵌着器では光伝導体を通して歯牙に照射され、光触媒の作用により歯牙の漂白が行われるが、この場合、紫外線の照射は歯牙嵌着器内に行われるので、口腔内の火傷の危険性はない。
【００１２】
また、本願第2発明では歯牙を差込溝に差し込むと共に、差込まれた歯牙と他の歯牙を噛合わせ、この噛合わせ力により貯留袋を圧縮させて内部のは上下歯牙の噛合わせ力により圧縮され、内部の光触媒を含む漂白剤溶液を放出ノズルより歯牙に放出させて紫外線の照射による光触媒の作用により歯牙の漂白を行うものである。
【００１３】
即ち、本願第2発明では上下歯牙の噛合わせ力により光触媒を含む漂白剤溶液貯留袋を圧縮させて内部の溶液を放出ノズルを通して歯牙に放出させるため、本願第1発明のように予め光触媒を含む漂白剤組成物を歯牙に塗布しておく必要はない。
【００１４】
また、本願第2発明では第1発明と同様に、紫外線の照射は歯牙嵌着器内に行われるので、口腔内の火傷の危険性はない。
【００１５】
なお、本願第1発明及び第2発明において歯牙の嵌着器の隙間にシリコン樹脂、シリコンゴム等で構成される紫外線遮断幕を設けるようにすれば、紫外線照射による口腔内の火傷をより確実に防止できる。
【００１６】
本願第1、第2発明では自然歯牙の他、義歯にも適用できるが、本願第3発明では特に義歯を対象とするものであり、この発明では義歯に二酸化チタンと過酸化水素水の溶液等からなる光触媒を含む漂白剤組成物を塗布した後、ケース本体内に設けた歯牙の嵌着部に義歯を嵌着し、ケース本体の蓋体を閉じ、紫外線照射器より紫外線を光ファイバー束を通して蓋体に設けた光ファイバー束の先端部の固定部より義歯に照射され、光触媒の作用により義歯の漂白が行われる。
【００１７】
また、光触媒を含む漂白剤組成物を前以って義歯に塗布することなく、ケース本体内に光触媒を含む漂白剤溶液を収容して嵌着された義歯を浸漬させるようにしてもよい。
【００１８】
【実施例】
以下、この発明の実施例を示す。
図1〜図５は、本願第1発明の歯牙漂白光照射装置を示すもので、１は紫外線照射器、２は光ファイバー束で、紫外線照射器１より照射される紫外線は人体に有害な波長をカットするフィルター2aを通して光ファイバー束２に導出され、また３は歯牙の嵌着器である。
【００１９】
歯牙の嵌着器３はその外壁にはステンレス又はアルミ等の紫外線遮断材質で構成された外側カバー４を設け、また嵌着器３の内部には上端乃至下端を開放した歯牙の差込溝５を形成し、差込溝５の壁面には透明樹脂で構成される交換可能な内側カバー６を設け、更に差込溝５の両端部などの嵌着器3の隙間にはシリコン樹脂、シリコンゴム等で構成される紫外線遮断幕７を設ける。
【００２０】
一方、歯牙の嵌着器３の外壁には歯列方向に沿ってガイド溝８を形成し、ガイド溝８には光ファイバー束２の先端部９を係止させ、嵌着器３の外壁と差込溝４との間には石英硝子又は透明樹脂等で構成される光伝導体10を介在させる。
【００２１】
本願第1発明は、以上のように構成され、漂白すべき歯牙ａには予め二酸化チタンと過酸化水素水の溶液等からなる光触媒を含む漂白剤組成物を塗布して差込溝５に差込む。
【００２２】
一方、紫外線照射器１より照射される紫外線は光ファイバー束２を通して嵌着器３に導き、嵌着器３では光伝導体10を通して歯牙ａの表面に照射され、これにより二酸化チタンの光触媒の作用により過酸化水素により歯牙の漂白が行われる。
【００２３】
また、ガイド溝８に沿って光ファイバー束２の先端部９を移動させて紫外線照射を行えば、歯列方向に沿った歯牙ａの漂白を行うことができる。
【００２４】
この場合、紫外線が内部に照射される歯牙の嵌着器３はその外壁をステンレス又はアルミ等の紫外線遮断材質で構成された外側カバー４で覆い、且つ差込溝５の両端部などの嵌着器3の隙間にはシリコン樹脂、シリコンゴム等で構成される紫外線遮断幕７が設けられているため、紫外線が嵌着器３の外部に漏れることなく、したがって紫外線により口腔内の火傷の危険性はない。
【００２５】
図6〜図８は、本願第２発明の一実施例を示すものであり、ここで３は透明樹脂からなる歯牙の嵌着器で、歯牙の嵌着器３の底部には光触媒を含む漂白剤溶液の貯留袋11が設置され、貯留袋11の両端には上方に環状の放出ノズル12が設けられ、放出ノズル12の上端部には放出口13，…を設ける。
【００２６】
一方、４は内側に石英硝子又は透明樹脂等で構成される光伝導体10を設けたステンレス製の外側カバーで、外側カバー４の底部には押ボタン14が設けられる
【００２７】
なお、この実施例では歯牙の嵌着器３と外側カバー４とは分離可能にして使い捨て交換可能なものとする。
【００２８】
この実施例においては、上記実施例のごとく漂白すべき歯牙には予め二酸化チタンと過酸化水素水の溶液等からなる光触媒を含む漂白剤組成物を塗布することなく、歯牙の嵌着器３における差込溝５内に差込まれる。
【００２９】
この状態で上下歯牙を噛合わせると、押ボタン14の押上により貯留袋11を圧縮させて内部の溶液は放出ノズル12を通って放出口13，…より歯牙に放出させれ、更に光ファイバー束２を通して照射される紫外線されるので、光触媒作用による歯牙の漂白が行われる。
【００３０】
図９〜図11は、本願第3発明の実施例を示すものであり、15は反射鏡付き紫外線照射ランプ１を収納した紫外線ランプケース、16は内部に漂白すべき義歯ｂの嵌着器３を備えたケース本体、17はケース本体16の蓋体であって、蓋体17の内面には閉じた状態でケース本体に嵌着された歯牙と対向状に光ファイバー束２先端部の固定部18が設けられ。
【００３１】
漂白する義歯ｂには予め光触媒を含む漂白剤組成物溶液を塗布してからケース本体16に嵌着してもよいが、この実施例ではケース本体16内に光触媒を含む溶液の水槽19を設け、水槽19内に歯牙の嵌着器３を設け、嵌着された義歯ｂを水槽19内の光触媒を含む溶液に浸漬させるようにしており、更にこの実施例では出来るだけ使用溶液量を少なくして義歯ｂが浸漬されるように水槽19の深さを調整してある。
【００３２】
一方、固定部18には義歯ｂの歯列に沿って窓20，…が設けられ、紫外線照射ランプ１より照射された紫外線は光ファイバー束２を通って窓20，…より義歯ｂに照射され、ここで義歯ｂの光触媒による漂白処理が行われる。
【００３３】
なお、この実施例ではケース本体16に蓋体17を被せることにより、紫外線照射ランプ１が自動的にセットされ、紫外線が照射させるようにしてある。
【００３４】
また、照射時間は任意に調整可能とし、また漂白処理された義歯ｂを取出す時にはチャイム等で終了を知らせ、更に途中で義歯ｂを取出す時には蓋体17を開いた時に紫外線ランプ１が自動的に消灯するようにしておく。
【００３５】
【発明の効果】
以上要するに、この発明によれば紫外線照射による口腔内の火傷等の危険性がなく、しかも極めて衛生的に歯牙の光触媒作用による漂白処理ができる。
