a curable dental composition (Y) comprising a hydrophilic radical polymerizable monomer (d-1) containing no acidic group, a hydrophobic radical polymerizable monomer (d-2) containing no acidic group, a chemical polymerization initiator (e), a photopolymerization initiator (f), and a filler (g),
the filler (g) being a filler treated with a surface treatment agent, and having an average particle diameter of 0.01 to 50.0 μm,
the surface treatment agent comprising a silane coupling agent (A) represented by general formula [1], and an organosilazane (B) represented by general formula [2].

摘要： A biocompatible composite material for controlled release is disclosed, comprising a biocompatible metal oxide structure with a loaded network of pores. The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.

摘要： The invention relates to a method to derive a medical form body of lithium silicate glass ceramic. To increase its strength it is proposed that in the form body comprising lithium silicate glass or containing lithium silicate glass the lithium ions are replaced by alkali ions of greater diameter to generate a surface compressive stress. To this end the form body is covered with a melt containing an alkali metal for which an aliquoted quantity of salt containing the alkali metal is used.
