Two-stage photocuring process for a dental composition |
摘要 |
The invention relates to photopolymerizable dental compositions of ethylenically unsaturated monomers and/or polymers thereof which are curable in two curing steps. Besides being comprised of fillers, said compositions also contain a photoinitiator component I having a light absorption maximum of <450 nm and a molar extinction of the light absorption of <10 at wavelengths of 470 nm or higher, and a photoinitiator component II having a molar extinction of the light absorption of >20 at least at one wavelength of at least >450 nm.
