title: Etched-metal resin-bonded intracoronal cast restorations. Part II: Design criteria for cavity preparation.
abstract: Intracoronal cast restorations can now be designed without dentinal involvement and with minimal alterations of the enamel. Exposure of the dentin is avoided during cavity preparation unless necessitated by disease, trauma, or previous restorations. Bonded retention also compensates for reduced frictional retention and provides support to weakened cusps. This article compared conventional intracoronal cast restorations with a design based on resin-bond retention. The proposed etched-metal resin-bonded restorations were found to be less invasive and more retentive.
