Classification and application of cementation alternatives

More important than any resin cement is the marginal fit and retentive nature of the ceramic restoration to be bonded. Cementation should not be intended to compensate for poor dentistry, but to assist in producing superior aesthetic results. Responding to the demand for all-ceramic restorations, dental manufacturers continue to refine the resin cements used in luting for this modality. The ideal resin cement for ceramic restorations must demonstrate low viscosity; easy loading; a film thickness which facilitates complete seating high strength; and excellent wear resistance. This article reviews the available resin cements, with particular focus on a new type of initiator and stabilizer for light- and dual-cured resin cements.
