[Is Immediate Dentin Sealing of added value in partial indirect restoration?]

Full crowns/rebates are based on the principle of macro-mechanical retention. Nowadays, indirect partial restorations can also be bonded predictably to tooth tissue, just like direct restorations. Therefore, adapting the preparation form to the restoration is unnecessarily invasive. Partial ceramic restorations are mainly used if the morphology cannot be properly restored with direct restorations. In case of exposed dentin, an immediate dentin sealing (IDS) can prevent failures. An IDS gives a significantly higher bond strength and therefore a longer survival of partial glass-ceramic restorations.
