Abstract
Dental restorative compositions are described comprising a finely divided filler mixed with a resin binder that can be activated to cause it to set in situ after application to a tooth surface or within a tooth cavity. The resin binder has as its primary component the reaction product of an alicyclic diacid (or its anhydride) polyfunctional material that has been reacted to form an ester with each of two acrylate or methacrylate materials, which may be the same but that preferably are different.
