What is the cement of choice for a lithium disilicate (e.max) crown?

  1. Resin cement
  2. Zinc phosphate
  3. Glass ionomer
  4. Polycarboxylate
Show answer and explanation

Correct answer: A. Resin cement

  • A. Correct. Lithium disilicate is best bonded with resin cement after HF etching and silane, maximizing strength and retention.
  • B. Zinc phosphate provides no adhesive bond and is not recommended for bonded ceramics.
  • C. Glass ionomer is used for high-strength zirconia/metal copings, not optimally for etchable e.max.
  • D. Polycarboxylate is not the recommended luting agent for lithium disilicate.
