Description
カルシウム系の生物活性セメント又は粒子は、様々な歯科用途における硬質組織及び軟質組織の治療を容易にする機能を証明している。バイオガラス、リン酸カルシウム系セメント、ヒドロキシアパタイト系材料、アルミン酸カルシウム系セメント及びポルトランドセメント等の材料は、硬質組織及び軟質組織の補修に使用されてきたわずかなカルシウム系生体材料である。これらのセメントの具体的な歯科用途としては、例えば、歯髄覆罩剤、歯髄切断剤、象牙質及びセメント質における破断(breach)用の歯根補修材料、歯根端充填材料及び骨移植剤のような選択肢が挙げられる。これらの材料としては、酸性、中性又は塩基性の水性環境中で反応してセメント系構造体を形成することができる水系セメントがある。
本発明は、カルシウム系セメントの新規のポリマー浸潤構造体を提供する。ポリマー浸潤構造体は、凝結したカルシウム系セメント又は凝結性のカルシウム系セメントの表面を安定化させ、流失(washout)を防ぎ且つ所望の位置で修復物を安定化させる。
1)窩洞形成が歯内で起こる。形成の間、歯髄の露出が起こる。止血(出血の調節)を生理食塩水に浸したコットンペレットを用いて行う。クロルヘキシジン配合物(例えば、Ultradent Products Inc.製のConsepsis(登録商標))等の抗菌剤が、出血の調節を助けるのに適用され得る。
2)ProRoot(商標)MTA(DENTSPLY)、すなわちカルシウム含有セメントをその後、滅菌生理食塩水又は水中で混合し、露出部に慎重に塗布する。
3)露出部を含む全形成面をその後、自己エッチングプライマー接着剤、例えばXeno(登録商標)で処理する。Xeno(登録商標)自己エッチング接着剤は、二成分系材料であり、これは窩洞形成で塗布する前に混合される。材料を混合して、適切なブラシ又は塗布具を用いて塗布し、その後軽くエアを吹きかけた。市販されている他の自己エッチング材料を本手法におけるこの目的に使用してもよい。
4)塗布されたXeno(登録商標)自己エッチング接着剤及び形成全体を青色スペクトル範囲の可視光に露光して、接着層と複合Xeno接着剤との接合面の硬化を容易にする。
5)光硬化されたか、二重硬化されたか又は適切な自己硬化性の複合修復材(すなわち、DENTSPLY製のSpectrumTPH(登録商標))を適用して窩洞形成を充填し、且つ可視光硬化ユニットを用いて硬化させる。適切な仕上げ及び研磨をその後行って、修復を完成することができる。
