Abstract
Description
該フィラーが、珪藻土と、シリカ粒子とを含み、
該歯科印象材用基材中の該珪藻土と該シリカ粒子との質量比率が4/1〜1/1である、歯科印象材用基材を提供する。
本開示の一態様は、水、アルギン酸塩、及びフィラーを含む歯科印象材用基材(本開示で、「基材」ということもある。)を提供する。本開示の基材は、アルギン酸塩系歯科印象材の基材として使用される。本開示の基材において、フィラーは、珪藻土と、シリカ粒子とを含む。本開示の歯科印象材用基材は、その特定の配合組成、特に、珪藻土とシリカ粒子との組合せを含むことに起因して、低剪断速度下で大きい剪断応力を有することによって、歯科印象材の製造時(すなわち基材と硬化材との練和時)及び使用時(すなわち印象採取時)の良好な取扱い性を与える。また、高剪断速度下では小さい剪断応力を有することによって、基材の製造時及び基材と硬化材との練和時の良好な取り扱い性を与える。
水:約65質量%〜約80質量%、
アルギン酸塩:約4質量%〜約5質量%、及び
フィラー:約15質量%〜約30質量%、並びに、
任意成分として
防腐剤:約0質量%〜約1質量%、
硬化遅延剤:約0質量%〜約1質量%、
香料:約0質量%〜約0.1質量%、及び
界面活性剤:約0質量%〜約1質量%、
の1種以上を含む。
本開示の一態様は、上述したような本開示の一態様に係る基材と、硬化材とを含む、歯科印象材を提供する。硬化材としては、アルギン酸塩系歯科印象材の硬化材として従来公知の種々の組成物を用いることができる。典型的な態様において、硬化材は、溶剤及びゲル化剤を含む。硬化材は、硬化遅延剤、界面活性剤、表面改質剤、着色剤、フィラー等を更に含んでよい。
歯科印象材用基材及び硬化材は、それぞれ、例えば配合成分を公知の撹拌混合器で混合する方法で製造できる。撹拌混合器としては、ボールミル、リボンミキサー、コニーダー、インターナルミキサー、スクリューニーダー、ヘンシェルミキサー、万能ミキサー、レーディゲミキサー、バタフライミキサー等を使用できる。本開示の歯科印象材は、上記のようにして製造された基材と、硬化材との組合せとして提供されることができる。典型的な態様において、基材及び硬化材は、それぞれパッケージ内に封入された状態で提供され、これらのパッケージを公知の自動練和器に装着して、基材と硬化材とを所定比率で自動練和することにより、印象材ペーストが提供される。
表1に示す配合成分(硬化材について)及び表2に示す配合成分(基材について)のそれぞれを、常法で室温にて混合し、硬化材ペースト及び基材ペーストを得た。
(1)珪藻土及びシリカ粒子の粒子径
走査型電子顕微鏡((株)日立ハイテクノロジーズ社製「S4800」)を用い、加速電圧3.0kV、観察倍率4000倍にて、基材の350μm×250μmの視野サイズ及び、観察倍率80000倍にて、1.5μm×1.2μmの視野サイズの電子顕微鏡像を得た。顕微鏡像全体から任意に、上記の観察倍率4000倍の電子顕微鏡像から珪藻土粒子20個、及び上記の観察倍率80000倍の電子顕微鏡像からシリカ一次粒子20個をそれぞれ選択した。なおシリカ粒子は基材中で凝集して二次粒子を形成していたが、輪郭が全周で明瞭に確認できる一次粒子を20個選択した。珪藻土及びシリカ粒子のそれぞれについて、20個の長径を画像上で計測した。20個の平均値をそれぞれ、珪藻土の平均粒子径、及びシリカ粒子の平均一次粒子径とした。結果を表2に示す。
上記で得た硬化材ペーストと、上記で得た実施例及び比較例に係る基材ペーストの各々とを常法にて室温で練和して歯科印象材を調製した。
表2に示す配合の実施例及び比較例に係る基材ペーストの剪断応力及び粘度を、レオメーター(マルバーン社製 Gemini 150/200)を用いて測定した。測定剪断速度範囲は1秒-1〜1500秒-1である。結果を表2に示す。
