Stable and substantially filled cationic dental compositions are described which include:
(1) at least one cationically reactive compound (A);
(2) at least one dental filler (B);
(3) optionally, at least one dispersant (C) composed of at least one organic polymer or copolymer;
(4) at least one cationic photoinitiator (D); and
(5) optionally, at least one photosensitizer (E). The dental filler (B) is treated with at least one organosilicon coupling agent (F), and
at least one compound (G). The organosilicon coupling agent (F) has at least one reactive function (rfA) directly linked to a silicon atom forming after activation of a chemical bond with the dental filler, and at least one reactive function (rfB) not directly linked to a silicon atom, forming after activation, a chemical bond with a reactive function (rfC) of the compound (G).
本文介绍了一种稳定且填充充足的阳离子牙科组合物,其中包括:(1)至少一种阳离子反应化合物(A);(2)至少一种牙科填充物(B);(3)可选地,至少一种由至少一种有机聚合物或共聚物组成的分散剂(C);(4)至少一种阳离子光引发剂(D);以及(5)可选地,至少一种光敏剂(E)。牙科填充物(B)经过至少一种有机硅偶联剂(F)处理,以及至少一种化合物(G)。有机硅偶联剂(F)具有至少一个反应功能(rfA),直接连接到形成化学键的硅原子上,与牙科填充物发生作用;以及至少一个反应功能(rfB),在激活后不直接连接到硅原子,与化合物(G)的反应功能(rfC)形成化学键。
