What is the best cement for bonding an all-ceramic crown?
Show answer and explanation
Correct answer: B. Resin cement
Resin cements (dual-cure or light-cure) provide the strongest bond for all-ceramic restorations by combining chemical adhesion with micromechanical retention. They also improve the fracture resistance of ceramic crowns by supporting the internal structure. Glass ionomer cements are chemically adhesive but lack the strength and translucency required for all-ceramic esthetic restorations. Zinc phosphate and polycarboxylate cements are mechanically retentive only and are not ideal for all-ceramic restorations.
