The patient chose the most esthetic option and lithium disilicate crowns will be placed. Which cement is most appropriate?
Show answer and explanation
Correct answer: A. Dual-cure resin cement
- A. Correct. Lithium disilicate (e.glass-ceramic) crowns are bonded with resin cement; dual-cure resin cement provides strong adhesion and reliable polymerization beneath less translucent restorations, maximizing strength and esthetics.
- B. Glass ionomer lacks the bond strength and esthetics optimal for bonded all-ceramic crowns.
- C. Zinc phosphate is a non-adhesive luting cement, unsuitable for bonded glass-ceramics.
- D. Polycarboxylate is a conventional luting cement and does not provide the adhesive bond ceramics need.
