Description
A社製のウレタンアクリレートオリゴマー、B社製のウレタンアクリレートオリゴマー及びC社製のウレタンアクリレートオリゴマーの3種類に、それぞれ、過酸化ベンゾイルを0.5wt%添加して攪拌した混合液aを作製し、さらに、前述した3種類のオリゴマーに、それぞれ、ジメチルパラトルイジンを0.5wt%添加して攪拌した混合液bを作製した。
圧縮方向:(6/12)×0.05=0.025mm
引張り方向:(25.2/20)×0.05=0.0563mm
となり、いずれも20μmの変形に対応できることがわかる。同様に、他の8種類の試作の場合も、20μmの変形に対応できる。なお、セメント層を50μmと仮定したのは、修復物を直接歯牙や支台歯に入れて適合性を試す(以下、試適)ときに、数十μmの余白がないと修復物がとれなくなってしまうため、試適後の取り外しのための余白を想定して50μmと仮定した。
圧縮方向:(1.28/12)×0.05=0.0053mm
引張り方向:(0.45/6)×0.05=0.0023mm
となり、20μmの変形に対応できないことがわかる。
