Description
印象材50、16、17、18、19は、再利用可能な発光印象トレイ8にきちんと適合する単回使用のトレイ1、1aに事前埋設され得る。特定の各トレイ8には、特定の一致する事前埋設トレイインサート1、1aを有し得る。使用中、開業医は、事前埋設トレイインサートを、光保護オーバーパッケージ51(バッグ、ポーチ、ラップ、トレイなど、不図示)から外すだけであろう。次に、ユーザーは、事前埋設インサートを発光トレイ8に置き、起動モジュール2を取り付け、印象材を覆う非粘着性の保護ライナー又は蓋48を取り外す。ユーザーは、トレイを患者の口に挿入し、トレイと患者の位置を合わせ、モジュール2を起動し、これによりLED6、ライトパイプ30(又はその他の硬化光源)が照明する。光硬化印象材50、16、17、18、19は、1秒未満で硬化し得る。
印象材50、16、17、18、19は、単回使用の発光印象トレイ8b、8c、8e、8fに事前埋設され得る。使用中、開業医は、事前埋設トレイを光保護オーバーパッケージ51(バッグ、ポーチ、ラップ、トレイなど、不図示)から外し、起動モジュール2を取り付けるだけであろう。その後、ユーザーは、印象材を覆っている非粘着性保護ライナー又は蓋48を外す。ユーザーは、トレイを患者の口に挿入し、トレイと患者の位置を合わせて、モジュール2を起動し、これにより、LED6、ライトパイプ30(又はその他の硬化光源)が適切な時間照明する。光硬化印象材50、16、17、18、19は、1秒未満で硬化し得る。
