Embodiment Construction
[0023] The following examples are used to explain the present invention, but not to limit the present invention.
[0024] Dental filling composite "Vernus / Heraeus Kulzer", consisting of the following components:
[0026] B Dental glass, as an inorganic filler, particle size is about 1 μm
[0027] C Silicic acid, as an inorganic filler, the original particle size <40nm
[0028] D stabilizer, initiator
[0029] A sample was taken from the above material and hardened with a "Translux Energy" lamp.
[0030] In a blender, medium-diameter, about 5 nm Ag nanoparticles (BioGate, Erlangen) were uniformly added to the remaining material at a concentration of about 50 ppm over 30 minutes.
[0031] A sample was taken again and hardened with a "Translux Energy" lamp.
[0032] The results showed no color difference between the two hardened samples.
[0033] It is of course possible that the silver nanoparticles or their diffusion have been introduced at the...
