Description
で示される化合物であることを特徴とする歯科用複合材料硬化体用プライマー組成物である。
で示される(B)芳香族アミンである。
そのような場合には、歯科用複合材料の配合成分として説明したのと同様の無機フィラーが、25〜75質量%程度含まれたものを用いるのが好適である。
市販の歯科用複合材料である「エステライト」(トクヤマデンタル製)及び「ソリデックス」(松風社製)を10×10×3mmのポリテトラフルオロエチレン製モールドに充填し、透明ポリプロピレンフィルムで圧接して酸素を遮断した状態で光重合することで「エステライト」及び「ソリデックス」レジン硬化体を得た。また、「エステニア」(クラレ社製)を10×10×3mmのポリテトラフルオロエチレン製モールドに充填し、透明ポリプロピレンフィルムで圧接して酸素を遮断した状態で光重合、引き続き加熱重合(100℃で15分)することで「エステニア」レジン硬化体を得た。
歯科用金−銀−パラジウム合金「金パラ12」(10×10×3mm)の表面を#1500の耐水研磨紙で磨いて平滑にした後、その研磨面に接着面積を固定するために3mmφの穴を開けた接着テープを貼り付けた。この模擬窩洞内に、各実施例の歯科用プライマー組成物をそれぞれスポンジで塗布し、20秒間放置した後圧縮空気を約5秒間吹き付けた。その後、歯科用レジンセメント「ビスタイトII(トクヤマデンタル社製)」付属のセメントを模擬窩洞内に充填した後、その上から直径8mmφのステンレス製のアタッチメントを圧接して、接着試験片を作製した。その後、上記接着試験片を37℃の水中に24時間浸漬した後、引っ張り試験機(オートグラフ、島津製作所製)を用いてクロスヘッドスピード2mm/minにて「金パラ12」との接着強度を測定した。
プライマーA液(包装(I))として、0.3gのPM、0.7gのMAC−10及び0.5gのUDMAを3.5gのアセトンに溶解し均一溶液を得た。別途、プライマーB液(包装(II))として0.5gのDMPT、0.3gの水及び4.2gのアセトンを混合して均一溶液を得た。なお、これらA液及びB液はいずれも容量10mlのガラスサンプル瓶中で調整した。
容量20mlのガラスサンプル瓶中で0.3gのPM、0.7gのMAC−10、0.5gのUDMA、0.5gのDMPT、0.3gの水及び7.7gのアセトンを混合して均一溶液を得、これを歯科用プライマー組成物とした。なおこの組成は、実施例1において、プライマーA液とプライマーB液とを等質量ずつ採取、混合した場合と同じである。
DMPTに代えて、DMBEを用いた以外は比較例1と同様にして歯科用プライマー組成物を調整し、これを用いてレジン硬化体に対する接着強度を測定したところ、14.1MPaの初期接着強度が得られた。
プライマーB液に配合するアミンの種類を、DMPTに代えて、DMBEを用いた以外は実施例1と同様にして歯科用プライマー組成物(プライマーA液及びプライマーB液)を調整し、これを用いてレジン硬化体に対する初期接着強度を測定したところ、接着強度は5.4MPaであった。
プライマーB液に配合するアミンの種類を、DMPTに代えて、DEPT又はPEATとした以外は、実施例1と同様の操作を行ってプライマー組成物を得、レジン硬化体に対する初期接着強度を測定した。その結果、DEPTを用いた場合は16.1MPa、PEATを用いた場合は15.3MPaであった。
プライマーB液に配合するアミンの種類を、DMPTに代えて、TEOA又はDMEMとした以外は、実施例1と同様の操作を行ってプライマー組成物を得、レジン硬化体に対する初期接着強度を測定した。その結果、TEOAを用いた場合は5.6MPa、DMEMを用いた場合は4.8MPaであった。
プライマーB液にアミンを配合せず、0.3gの水と4.7gのアセトンの混合溶液とした以外は、実施例1と同様の操作を行ってプライマー組成物を得、レジン硬化体に対する初期接着強度を測定した。その結果、接着強度は4.1MPaであった。
プライマーB液に配合するアミン(及びアセトン)の量を表3に示すように変化させた以外は、実施例1と同様の操作を行ってプライマー組成物を得、レジン硬化体に対する初期接着強度を測定した。結果を表3に併せて示す。
プライマーB液に配合する水及びアセトンの量を表3に示すように変化させた以外は、実施例1と同様の操作を行ってプライマー組成物を得、レジン硬化体に対する初期接着強度を測定した。結果を表3に併せて示す。
プライマーA液に配合する酸性基を有さない多官能の重合性単量体及びアセトンの量を表4に示すように変化させた以外は、実施例1と同様の操作を行ってプライマー組成物を得、レジン硬化体に対する初期接着強度を測定した。結果を表4に併せて示す。
プライマーA液に配合する酸性基を有さない多官能の重合性単量体を、UDMAに代えてD26Eとした以外は、実施例1と同様の操作を行ってプライマー組成物を得、レジン硬化体に対する初期接着強度を測定した。結果を表4に示す。
プライマーA液に配合する揮発性有機溶媒を、アセトンに代えてIPAとした以外は、実施例1と同様の操作を行ってプライマー組成物を得、レジン硬化体に対する初期接着強度を測定した。結果を表4に示す。
プライマーA液及びB液双方で、調製に用いた揮発性有機溶剤をアセトンに代えてIPAとした以外は、実施例1と同様にしてプライマー組成物を得、レジン硬化体に対する初期接着強度を測定した。結果を表4に示す。
プライマーA液に配合する酸性基含有重合性単量体として、PMを配合せず、代わりにMAC−10の量を1.0gとした以外は、実施例1と同様の操作を行ってプライマー組成物を得、レジン硬化体に対する初期接着強度を測定した。結果を表4に示す。
プライマーA液及び/又はB液の組成を表5に示した組成のものにした以外は実施例1と同様の操作を行って、レジン硬化体に対する初期接着強度を測定した。結果を表5に示す。
レジン硬化体として、エステライト硬化体に代えて、ソリデックス硬化体およびエステニア硬化体を用い、実施例1と同じプライマー組成物を用いて接着強度を測定した。その結果、ソリデックス硬化体に対して13.8MPa、エステニア硬化体に対して13.1MPaの接着強度が得られた。
(メタ)アクリレート系の接着材としてビスタイトII付属のセメントに代えて、マルチボンド付属のセメントおよびパナビアF2.0付属のセメントを用い、実施例1と同じプライマー組成物を用いてエステライト硬化体に対する接着強度を測定した。その結果、マルチボンド付属セメントを用いた場合には16.5MPa、パナビアF2.0付属セメントを用いた場合には14.0MPaの接着強度が得られた。
