The most common aspect in gold inlay and amalgam cavity design is: (A) Axiopulpal bevel, (B) Gingival bevel, (C) Occlusal bevel, (D) Axiofacial bevel
Answer is B. The gingival bevel removes the unsupported enamel and compensates for casting shrinkage. It is a feature of resistance form. Reverse bevel is given in inlay for lap sliding fit. It locks the restoration and prevents proximal displacement.
