ABSTRACT:
A phosphonate ester (vinyl phosphonic acid reacted with equimolar diol) will cure on command (e.g. exposure to light) in the presence of an initiator. By adding inert filler, poly(vinyl phosphonic acid), ion-leachable glass powder and water, a command-curable dental cement with glass ionomer characteristics is obtained.
