Abstract
The dental plate liner includes: a paste (i) containing (A) a (meth)acrylic acid-based polymer, and a fluorine-containing (meth)acrylic acid-based polymerizable monomer in which (A) the (meth)acrylic acid-based polymer has a solubility of less than 20 mass %; and a paste (ii) containing a (meth)acrylic acid-based polymerizable monomer in which (A) the (meth)acrylic acid-based polymer has a solubility of 20 mass % or more, and a filler, in which at least one paste selected from the group consisting of the paste (i) and the paste (ii) contains a polymerization initiator, and in which the dental plate liner is used through mixing of the paste (i) and the paste (ii) immediately before use.
Claims7
A dental plate liner, comprising:
- a paste (i) consisting essentially of:
- (A) a non-cross-linked (meth)acrylic acid-based polymer, and
- (B) a fluorine-containing (meth)acrylic acid-based polymerizable monomer in which (A) the (meth)acrylic acid-based polymer has a solubility of less than 20 mass %;
- and
- a paste (ii) consisting essentially of:
- (C) a (meth)acrylic acid-based polymerizable monomer, which does not contain fluorine and in which (A) the non-cross-linked (meth)acrylic acid-based polymer has a solubility of 20 mass % or more, and
- (D) a filler, which is selected from the group consisting of a cross-linked polymer and an inorganic filler,
- wherein the paste (ii) does not contain (A) the non-cross-linked (meth)acrylic acid-based polymer,
- wherein at least one paste selected from the group consisting of the paste (i) and the paste (ii) contains (E) a polymerization initiator, and
- wherein the dental plate liner is used through mixing of the paste (i) and the paste (ii) immediately before use.
