Abstract
Description
本開示の一形態に従う歯漂白装置は、歯を漂白する有効成分を生成する生成装置と、前記生成装置により生成された有効成分を口腔内に供給する供給口が形成されたマウスピースとを備える。
一形態では、前記マウスピースのうちの上顎の歯および下顎の歯の少なくとも一方と対向し得るガイド面に前記供給口が形成されている。
一形態では、前記連結部が接続される入口側通路、および、前記入口側通路を流れるガスを前記供給口に案内する出口側通路が、前記マウスピースに形成され、前記出口側通路を流れるガスの流速が前記入口側通路を流れるガスの流速よりも低くなるように前記出口側通路および前記入口側通路が形成されている。
一形態では、前記咬合要素の内部に前記出口側通路が形成されている。
一形態では、前記ガイド面のうちの歯茎と対向し得る部分に前記ガイド面から突出した桟が形成されている。
図1を参照して、歯漂白装置10の構成について説明する。
歯漂白装置10は、歯を漂白する歯漂白流体を生成する生成装置30、歯漂白流体を供給または排気するマウスピース100、および、生成装置30とマウスピース100とを連結する連結部20を備える。歯漂白流体の一例は帯電微粒子水を含む気体であり、帯電微粒子水に含まれるラジカル種は歯を漂白する有効成分の一例である。
ユーザーはマウスピース100を口腔内に装着し、口を閉じることによりマウスピース100を保持する。その後、スイッチ32がオフからオンに切り替えられることにより放電部40が動作しはじめ、放電部40により帯電微粒子水を含む歯漂白流体が生成される。生成装置30により生成された歯漂白流体は、生成装置30、連結部20、および、マウスピース100の順に流れる。マウスピース100の入口側通路101に流れ込んだ歯漂白流体は、出口側通路102および供給口103を通過して口腔内に供給される。このため、帯電微粒子水が歯に到達し、帯電微粒子水に含まれるラジカル種が歯に付着している着色性の有機物質から電子を奪う。このため、着色性の有機物質が分解され、歯が漂白される。
(1)歯漂白装置10は生成装置30およびマウスピース100を備える。この構成によれば、ユーザーは、有効成分を歯に供給する物体であるマウスピース100を咬むことにより、その物体を歯の漂白に適した位置に保持できる。すなわち、ユーザーは、有効成分を歯に供給する物体を手で持たなくとも歯を漂白できる。このため、使いやすい歯漂白装置10を提供できる。
図2を参照して、歯漂白装置10の構成について説明する。実施の形態2の歯漂白装置10は、実施の形態1の歯漂白装置10に関する説明により明示されていない以下の構成を含む。
ユーザーは、上顎の歯または下顎の歯がマウスピース100の歯収容空間104に配置されるようにマウスピース100を口腔に装着し、上顎の歯および下顎の歯で咬合要素120を咬むことによりマウスピース100を保持する。マウスピース100が口腔に装着された状態によれば、咬合要素120の内側面121が上顎の歯と接触し、咬合要素120の外側面122が下顎の歯と接触する。
(6)マウスピース100は外側湾曲要素110を備える。この構成によれば、歯収容空間104に供給された歯漂白流体が外側湾曲要素110のガイド面111に案内されることにより、歯の並びに沿って流れやすい。このため、マウスピース100が外側湾曲要素110を含まない場合と比較して歯が効率的に漂白される。
図3を参照して、実施の形態3の歯漂白装置10の構成について説明する。実施の形態3の歯漂白装置10は、実施の形態2の歯漂白装置10に関する説明により明示されていない以下の構成を含む。
ユーザーは、上顎の歯または下顎の歯がマウスピース100の歯収容空間104に配置されるようにマウスピース100を口腔に装着し、上顎の歯および下顎の歯で咬合要素120を咬むことによりマウスピース100を保持する。マウスピース100が口腔に装着された状態によれば、外側湾曲要素110のガイド面111が歯収容空間104の一部を隔てて歯の表面と対向し、内側湾曲要素130のガイド面131が歯収容空間104の一部を隔てて歯の裏面と対向する。さらに、咬合要素120の内側面121が上顎の歯と接触し、咬合要素120の外側面122が下顎の歯と接触する。
(8)前歯TFのおおよそ全部と対応するように供給口103が形成されている。この構成によれば、前歯TFへの有効成分の分配量に差が生じにくい。このため、各前歯TFにおける漂白の度合に差が生じにくい。
図5Aおよび図5B等を参照して、実施の形態4の歯漂白装置10の構成について説明する。実施の形態4の歯漂白装置10は、実施の形態3の歯漂白装置10に関する説明により明示されていない以下の構成を含む。
図6Aに示されるとおり、連結部20の連結通路21からマウスピース100の入口側通路101に歯漂白流体が供給される。入口側通路101の歯漂白流体は出口側通路102および供給口103の中間部分を通過して案内通路105に供給される。このため、歯漂白流体が前歯TFに到達し、その歯が漂白される。
(9)出口側通路102の流路面積が入口側通路101の流路面積よりも広い。この構成によれば、出口側通路102を流れるガスの流速が入口側通路101を流れるガスの流速よりも低くなる。このため、出口側通路102にガスが滞留しやすい。このため、出口側通路102に存在する有効成分がガス中に拡散しやすい。このため、有効成分の濃度の差が小さいガスが供給口103から案内通路105に供給される。このため、1つの歯の様々な部分への有効成分の分配量に差が生じにくい。このため、その歯の各部分における漂白の度合に差が生じにくい。また、複数の歯への有効成分の分配量に差が生じにくい。このため、それらの歯における漂白の度合に差が生じにくい。
図7を参照して、実施の形態5の歯漂白装置10の構成について説明する。実施の形態5の歯漂白装置10は、実施の形態4の歯漂白装置10に関する説明により明示されていない以下の構成を含む。
(12)歯漂白装置10はエアーポンプ55を備える。この構成によれば、歯漂白流体がエアーポンプ55の吐出圧力により生成装置30からマウスピース100に供給される。このため、生成装置30から口腔内に向かう歯漂白流体の流れが適切に形成される。このため、歯漂白装置10がエアーポンプ55を含まない場合と比較して歯が一層効率的に漂白される。
図8を参照して、実施の形態6の歯漂白装置10の構成について説明する。実施の形態6の歯漂白装置10は、実施の形態5の歯漂白装置10に関する説明により明示されていない以下の構成を含む。
(13)放電部40は冷却モジュール44により霧化電極41を冷却することにより霧化電極41に水を供給する。この構成によれば、例えば吸水用のタンクから霧化電極41に水を供給する構成と比較して生成装置30を小型化しやすい。
図9~図11を参照して、実施の形態7の歯漂白装置10の構成について説明する。実施の形態7の歯漂白装置10は、図1に示される実施の形態1の歯漂白装置10のマウスピース100に代えて、図9に示されるマウスピース200を備える。
ユーザーは、上側の唇収容空間204に上唇RUを配置し、下側の唇収容空間204に下唇RLを配置し、上唇RUと歯茎Gとの間に上側の桟230を配置し、下唇RLと歯茎Gとの間に下側の桟230を配置することによりマウスピース200を保持する。
図10に示されるとおり、連結部20の連結通路21からマウスピース200の出口側通路202に歯漂白流体が供給される。出口側通路202の歯漂白流体は供給口203から案内通路205に供給される。図11に示されるとおり、案内通路205の歯漂白流体は外側湾曲要素210のガイド面211に案内されることにより歯の並びに沿うように案内通路205を流れる。このため、歯漂白流体が上顎の歯および下顎の歯のおおよそ全部に到達し、それらの歯が漂白される。
(14)マウスピース200は上顎の歯および下顎の歯との間に案内通路205を形成し得る外側湾曲要素210を備える。この構成によれば、ユーザーがマウスピース200を口腔に装着することにより、上顎の歯および下顎の歯が併せて漂白される。このため、マウスピース200が外側湾曲要素210を含まない場合と比較して歯を漂白するためにかかる時間が短縮される。
図12および図13を参照して、実施の形態8の歯漂白装置10の構成について説明する。実施の形態8の歯漂白装置10は、図1に示される実施の形態1の歯漂白装置10のマウスピース100に代えて、図12に示されるマウスピース300を備える。
ユーザーは上顎の歯および下顎の歯で各咬合要素310を咬むことによりマウスピース300を保持する。マウスピース300が口腔に装着された状態によれば、咬合要素310よりも上側のガイド面211が上顎の歯の表面および上顎の歯茎Gの表面との間に案内通路330を形成する。また、咬合要素310よりも下側のガイド面211が下顎の歯の表面および下顎の歯茎Gの表面との間に案内通路330を形成する。
連結部20の連結通路21からマウスピース300の出口側通路202に歯漂白流体が供給される。出口側通路202の歯漂白流体は供給口203から案内通路330に供給される。案内通路330の歯漂白流体は外側湾曲要素210のガイド面211に案内されることにより歯の並びに沿うように案内通路330を流れる。このため、歯漂白流体が上顎の歯および下顎の歯のおおよそ全部に到達し、それらの歯が漂白される。
(15)マウスピース300は咬合要素310を備える。この構成によれば、ガイド面211と上顎の歯との間に形成される案内通路330と、ガイド面211と下顎の歯との間に形成される案内通路330とが咬合要素310により区画される。このため、上顎および下顎の歯の群毎に歯漂白流体の流れが形成され、マウスピース300が咬合要素310を含まない場合と比較して歯の並びに沿う歯漂白流体の流れが安定する。
図14~図16Bを参照して、実施の形態9の歯漂白装置10の構成について説明する。実施の形態9の歯漂白装置10は、図1に示される実施の形態1の歯漂白装置10のマウスピース100に代えて、図14に示されるマウスピース400を備える。
図16Aに示されるとおり、連結部20の連結通路21(図15参照)からマウスピース400の入口側通路401に歯漂白流体が供給され、その歯漂白流体が入口側通路401から出口側通路402に流れ込むことにより減速する。出口側通路402の歯漂白流体は供給口403の中間部分から案内通路405に供給される。このため、歯漂白流体が前歯TFに到達し、その歯が漂白される。
各実施の形態に関する説明は、本発明の歯漂白装置が取り得る形態の例示であり、本発明の歯漂白装置が取り得る形態を制限することを意図していない。本発明の歯漂白装置は、各実施の形態以外に、例えば以下に示される各実施の形態の変形例を取り得る。
・実施の形態2~6のマウスピース100の変形例によれば、出口側通路102の出口通路寸法が供給口103の供給口寸法と同じ、または、供給口103の供給口寸法よりも小さく設定される。
・実施の形態2~6のマウスピース100の変形例によれば、特定の歯と対向する位置に供給口103の形成位置が設定される。
・実施の形態2~6の歯漂白装置10の変形例によれば、連結部20が入口側通路101の全体に挿入される。このため、生成装置30から連結部20に供給されたガスは、入口側通路101と重畳した連結通路21、出口側通路102、および、供給口103の順に通過して歯収容空間104に供給される。
・実施の形態5または6の歯漂白装置10の変形例は、電動式のエアーポンプ55に代えて手動式のエアーポンプを備える。
・実施の形態5または6の共振回路53の変形例は、積層圧電トランス54の2次側電極、リアクトル、および、放電部40の霧化電極41が直列的に接続された回路構成を有する。
・実施の形態7のマウスピース200の変形例によれば、外側湾曲要素210の縁よりも供給口203に近い部分に桟230が形成される。
・実施の形態9のマウスピース400の変形例によれば、咬合要素420に複数の供給口403が形成される。
・各実施の形態の生成装置30の変形例は、グロー放電またはアーク放電等のようにコロナ放電とは異なる形態の放電を発生させる。
・各実施の形態の歯漂白装置10の変形例によれば、生成装置30とマウスピース100,200,300,400とが直接的に接続される。
前記マウスピース(100;400)は、前記マウスピースに供給された歯漂白流体の流速を低下させるべく前記供給口の上流に配置された内部空洞(102;402)を含み得る。この構成は、歯漂白流体の分配均一性の点で好ましい。
