Which sequence best reflects essential steps for a durable amalgam restoration, including condensation and finishing?

• A. Proper condensation and finishing, with accurate occlusion and margins.
• B. Quick finishing with minimal condensation to save time.
• C. Not checking occlusion at all.
• D. Using a low-cost material only.

Answer: (B)

Durability in an amalgam restoration depends on forming a dense, well-adapted mass through thorough condensation, followed by finishing that yields a smooth surface and proper occlusion and margins. Adequate condensation fills prep walls, eliminates voids, and ensures the amalgam is well condensed against the cavity floors and walls. If condensation is rushed or minimized, porosities and weak spots can form, and the marginal seal can be compromised, which undermines longevity. After achieving good condensation, you verify occlusion and margins to ensure the restoration contacts resistively in the bite and sits snugly at the margins, preventing microleakage and postoperative sensitivity. Finishing and polishing come next to produce a smooth, sealed surface that resists plaque accumulation and wear, and to refine margins for longevity. The option that focuses on quick finishing with minimal condensation undermines the restoration’s strength and seal, making it less durable. Not checking occlusion misses a critical functional aspect that, if unresolved, can cause improper wear or high spots. Choosing a low-cost material addresses material choice rather than the procedural sequence needed to ensure durability.
