The relationship of bevels to the adaptation of intracoronal inlays.
The elongation of Types II and III gold alloys ranges from 20 to 35 per cent. It has therefore been proposed that a nonbeveled margin could be "pulled" (elongation) to close the margin. However, in clinical practice, it is difficult to pull gold over an unsupported space to close the margin. Furthermore, the thin area of gold that would be pulled toward the margin could easily be sheared or abraded during finishing. Malleting or swaging a beveled margin is a more sucessful technique of adapting cast gold to the cavosurface angles.
