Which property is essential for initial retention during crown seating?

• A. Color
• B. Odor
• C. Hardness
• D. Bond strength

Answer: (D)

Bond strength determines how well the luting agent adheres to both the tooth structure and the crown, which is what keeps the crown in place as it’s seated and the cement begins to set. During seating, the cement must resist dislodging forces and maintain a seal, so a strong bond helps prevent the crown from shifting or washing out before full set. Color is purely esthetic and does not affect adhesion, odor is irrelevant to retention, and hardness affects wear resistance after setting—not the immediate retention during seating.
