The present invention has satisfactory grinding feel during form modified to express a high surface hardness after curing dental denture related material composition by containing an ionic sustained release glass and fluoride ions provision of various strengthening of the remaining tooth structure by sustained release of ions and secondary caries occurrence suppression, bacteria, fungi of attachment and dental denture-related material composition having both a prophylactic function of growth inhibition or the like including a . The invention relates to a powder material and a liquid two-component miscible ion sustained release denture base related material composition comprising a material, (a) a non-crosslinkable (meth) acrylate polymer, (b) ion sustained-release and includes a powder material component and (c) a monofunctional (meth) acrylate-based polymerizable monomer, and a liquid material component is configured to at least one of the one containing the (d) polymerization initiator material including glass, denture-related material composition. .BACKGROUND【課題】歯科用義歯床用関連材料組成物にイオン徐放性ガラスを含有することによって硬化後における高い表面硬さを発現するために形態修正時における切削感が良好であり、またフッ化物イオンを含む各種イオンの徐放による残存歯質の強化と二次的な齲蝕の発生抑制、細菌・真菌の付着及び増殖抑制等の予防的機能を兼備した歯科用義歯床用関連材料組成物の提供。【解決手段】粉材と液材から成る二成分混和型イオン徐放性義歯床用関連材料組成物であって、(a)非架橋性(メタ)アクリレート系ポリマー、(b)イオン徐放性ガラス、を含む粉材成分と(c)単官能性(メタ)アクリレート系重合性単量体、を含む液材成分とから構成され少なくともいずれかの一方に(d)重合開始材を含んでいる義歯床用関連材料組成物。【選択図】なし
