COMMAND-CURABLE COMPOSITION |
摘要 |
A light-curable dental cement composition contains (a) the reaction product of vinyl phosphonyl chloride and pentane 1,5 diol, (b) a photopolymerisation initiator, (c) ion-leachable aluminosilicate glass powder, (d) poly(vinyl phosphonic acid), (e) bisGMA as a photopolymerisable dimethacrylate resin, and water, inert filler and silanising agent. Upon mixing, glass is added last, the composition is put in place and, when ready, it is light-irradiated for 30 or 40 seconds to polymerise (e). The composition is immediately firm and the phosphonate groups adhere to tooth material while further slow curing by acid-base reaction continues. |
