過酸化水素、過酸化尿素などの漂白剤を含むジェルなどによる医院での、または家庭での歯の漂白は国内外で行われている。こられの漂白剤が塗布された歯にＵＶ，ブルー、赤外の波長の光を照射することにより漂白が促進されより短い時間で施術が完了することもよく知られている。その促進の機序は歯の着色部が光を吸収し発熱し酸化反応が促進されるとことによる。したがって光強度が高いほど漂白はより促進されるが歯の温度が高すぎると歯髄または周辺の歯肉などに対して熱作用による疼痛や炎症をおこすこともありうる。通常の漂白用の照射装置には口腔外から照射する装置が普及しているが漂白中に長時間、開口器で口をあけている状態が強いられる。照射前に印象材で歯型をとり歯型にあうトレーを作成しそのトレーに漂白剤を充填して歯にはめこみ酸化漂白をおこなう。したがってトレーを作成する手間がかかり漂白の手順の複雑化とコスト高を招いている。マウスピースタイプのものでは個人用であればよいが医院用であればマウスピースが口腔内に留置されるためマウスピースを滅菌するか、マウスピースを覆う使い捨てのドレープなどで被施術者間の相互感染を防いでいる。 Teeth bleaching in clinics or at home with gels containing bleaching agents such as hydrogen peroxide and urea peroxide is carried out at home and abroad. It is also well known that bleaching is accelerated by irradiating teeth coated with these bleaching agents with light of UV, blue and infrared wavelengths, and the treatment is completed in a shorter time. The mechanism of the promotion is that the colored part of the tooth absorbs light, generates heat, and the oxidation reaction is promoted. Therefore, bleaching is accelerated as the light intensity increases, but if the tooth temperature is too high, it may cause pain or inflammation due to thermal action on the pulp or surrounding gingiva. A device for irradiating from outside the oral cavity is widely used as an irradiation device for ordinary bleaching, but it is forced to keep the mouth open for a long time during bleaching. Take a tooth mold with impression material before irradiation, make a tray that matches the tooth mold, fill the tray with bleach, and oxidize and bleach it into the teeth. Therefore, it takes time and effort to prepare the tray, resulting in complicated bleaching procedures and high costs. If the mouthpiece type is for personal use, the mouthpiece is placed in the oral cavity for clinic use. Preventing infection.

第一に歯髄または周辺の歯肉などに熱作用による疼痛や炎症などを起こすことなしに安全に、より短い時間で歯の漂白を可能とする。第二に漂白中に長時間、開口器で口をあけている状態を避けマウスピース型の光照射装置とする。第三にトレーを作成することなしに即日漂白を可能とさせる。第４に患者間の相互感染を防ぐ安全性が確保された光照射装置とする。 First, it enables bleaching of teeth safely and in a shorter time without causing pain or inflammation due to thermal action on the pulp or surrounding gingiva. Secondly, a mouthpiece-type light irradiation device is used, avoiding a state where the mouth is opened for a long time during bleaching. Third, it allows bleaching on the same day without making a tray. Fourthly, a light irradiation device that ensures safety to prevent mutual infection between patients is adopted.

以上の課題を解決するための第一の発明は、歯漂白のためのレーザまたはＬＥＤによるマウスピース型の光照射装置において熱伝導性のよい透光性樹脂、あるいはゴムで充填された照射部に温度センサーを有し、また照射装置内に冷却チャンバーを有し、チャンバーに冷却液体が循環することによりレーザまたはＬＥＤの発熱を除熱し、光照射による歯の温度上昇を制御できるマウスピース型の光照射装置である。
第二の発明はマウスピース型の光照射装置を滅菌することなしに光を透過、散乱し、熱伝導性がよく、歯型がとれ、その形状が保持できる程度の低硬度の水性ジェルを含んだ交換容易なジェルパックである。 A first invention for solving the above-described problems is that a mouthpiece type light irradiation device using a laser or LED for tooth bleaching has an irradiation part filled with a light-transmitting resin having good thermal conductivity or rubber. Mouthpiece-type light that has a temperature sensor and a cooling chamber in the irradiation device, and the cooling liquid circulates in the chamber to remove heat from the laser or LED and control the temperature rise of the teeth due to light irradiation. Irradiation device.
The second invention includes a water-based gel having a low hardness enough to transmit and scatter light without sterilizing a mouthpiece-type light irradiation device, have good thermal conductivity, take a tooth shape, and maintain its shape. It is an easy-to-replace gel pack.

第一に歯髄または周辺の歯肉などに熱作用による疼痛あるいは炎症を起こすことなしに安全に、より短い時間で漂白を可能とし漂白の施術コストを削減し被施術者の施術快適性を向上させることができる。第二に漂白中に長時間、開口器で口をあけている状態を避け施術コストを削減し被施術者の施術快適性を向上させることができる。第三にトレーを作成することなしに即日漂白を可能とし手順を単純にして施術コストと施術の利便性を向上させることが可能となる。第四に被施術者間の相互感染を防ぎマウスピース型の光照射装置の滅菌作業をさけることで安全性と施術準備を単純にすることができる。
Firstly, bleaching can be performed safely and in a shorter time without causing pain or inflammation due to thermal action on the pulp or the surrounding gingiva, etc., reducing the cost of bleaching and improving the treatment comfort of the patient. Can do. Secondly, avoiding a state where the mouth is opened for a long time during bleaching, the treatment cost can be reduced and the treatment comfort of the treated person can be improved. Thirdly, bleaching can be performed on the same day without preparing a tray, and the procedure can be simplified to improve the treatment cost and the convenience of the treatment. Fourth, safety and treatment preparation can be simplified by preventing cross-infection between patients and avoiding the sterilization of the mouthpiece type light irradiation device.

＜他の実施形態＞
光源として半導体レーザが使用できる。半導体レーザはＬＥＤと同様、マウスピース型の光照射装置に設置できる小型の発振器が望ましい。また口腔外の唇、顔などに照射する場合、光照射装置の形状はマウスピース型とは異なる形状となる。ジェルパックは歯の漂白では覆いかぶせる袋部を有する必要はなく水性ジェルコンパートメント部のみでよい。水性ジェルコンパートメント部はマウスピース型の光照射装置に取り付けられるものとは異なる形状となる。水性ジェルの硬度は唇、顔の軟組織に合わせマウスピース型の光照射装置に取り付けられるものより低硬度となる。 <Other embodiments>
A semiconductor laser can be used as the light source. The semiconductor laser is preferably a small oscillator that can be installed in a mouthpiece-type light irradiation device, like the LED. Moreover, when irradiating lips, faces, etc. outside the oral cavity, the shape of the light irradiation device is different from the mouthpiece type. The gel pack does not need to have a bag portion to be covered for tooth bleaching, but only an aqueous gel compartment portion. The aqueous gel compartment has a different shape from that attached to the mouthpiece type light irradiation device. The hardness of the aqueous gel is lower than that attached to the mouthpiece type light irradiation device according to the soft tissues of the lips and the face.

ＬＥＤは1個あたり４５０ナノメータの青色波長で１５００ｍｗの出力を有する。4個の青ＬＥＤと白金温度センサーは熱伝導性接着剤によりマウスピース型の光照射装置にマウントされている。ＬＥＤの発熱はマウスピース型の光照射装置が冷却されると除熱される。これらＬＥＤと白金温度センサーは熱伝導性のよい透光性シリコンゴムで充填され光照射部は防水の機密性を有している。温度センサーは歯面温度を反映する温度をモニターし、歯面の温度制御をしながら光照射を可能としている。歯面温度が安全な42度Ｃを超えないような温度設定がされている。ＬＥＤ光源、温度センサーの電源ケーブル、センサーケーブルは耐水チューブで温度制御装置と光源電源に接続されている。
ＬＥＤ光源およびマウスピース型の光照射装置全体は熱伝導性が高いアルミニウム製であり、内部の冷却チャンバーにより冷却される。冷却チャンバーには冷却液体が循環されている。冷却液体はラジエータ、ファンにより冷却される。ポンプは温度制御器により設定温度を保つように冷却液体の循環のＯＮとＯＦＦを行う。マウスピース型の光照射装置に覆って取り付けられるジェルパックは伸縮性のあるポリエチレンの薄膜材質からなり、内部に水性ジェルコンパートメントを有している。ジェルパックのジェルコンパートメントは水性ジェルが漏れないよう溶着シールされている。水性ジェルはジェル化したときに光を透過するカルボキシメチルセルロースナトリウムなどの増粘剤を使用する。ジェルは光透過性、熱伝導率の良好な石英、サファイア粉末を重量で１％未満を含有している。粉末は光を反射し水性ジェルに均一に分散させるため光の波長より長い１−１０ミクロンの粒子径である。マウスピース型の光照射装置に装着された水性ジェルパックの水性ジェルコンパートメント部が噛まれて変形し歯型がとれる。ジェルパックが装着されたマウスピース型の光照射装置は一度取り出され、歯型の部位に過酸化水素、過酸化尿素などの漂白剤が充填され再び口腔内に留置され歯型部位に歯をはめ込み、光照射による漂白が施術される。ジェルパックは口腔内で舌の動きを妨げないテーパー上の形状となっている。 Each LED has an output of 1500 mw at a blue wavelength of 450 nanometers.

A cooling liquid is circulated in the cooling chamber. The cooling liquid is cooled by a radiator and a fan. The pump turns on and off the circulation of the cooling liquid so as to maintain the set temperature by the temperature controller. The gel pack that covers and is attached to the mouthpiece type light irradiation device is made of a stretchable polyethylene thin film material and has an aqueous gel compartment inside. The gel pack's gel compartment is welded and sealed to prevent leakage of the aqueous gel. Aqueous gels use thickeners such as sodium carboxymethylcellulose that transmit light when gelled. The gel contains less than 1% by weight of quartz and sapphire powder having good light transmission and thermal conductivity. The powder has a particle size of 1-10 microns longer than the wavelength of the light in order to reflect light and disperse it uniformly in the aqueous gel.
