Patent ID: 7855242

Claim:
A curable temporary removable restorative cement composition comprising: a polymerizable mono(meth)acrylate resin having a vapor pressure of 1 mm Hg or less at 20° C., wherein the polymerizable mono(meth)acrylate resin comprises the reaction product of lactide, glycolide, caprolactone, or a mixture comprising one or more thereof, and a hydroxyl-functional mono(meth)acrylate resin; a plasticizer; and a curing system for the mono(meth)acrylate resin, wherein the composition comprises, based on the total weight of the composition, about 20 to about 90 wt.% of a polymerizable mono(meth)acrylate; about 5 to about 80 wt.% of a non reactive plasticizer; and about 0.01 to about 5 wt.% of a curing system, wherein solid resins are excluded from the composition, wherein the composition, upon being cured, has a compression strength of less than 50 MPa, measured per ANSI/ADA Specification No. 66.
