ABSTRACT:
Process for separating a pre-polymerized composite dental filling, such as an inlay, from the hard substance of the tooth using a separating substance consisting of a sol formed from a substance swollen and dissolved in alcohol and forming an organic or inorganic gel. The separating substance is applied as a separating layer to the cavity prior to introducing the composite into the cavity and this facilitates the removal of the composite after hardening in the cavity. The separating layer is removed from the cavity, and the inlay is then cemented into the cavity after being tempered.
