b. Hand Finishing Instruments.
(1) Burnishers (BURNISHER, DENTAL). Burnishers (figure 2-23) are used to
polish, work-harden, or burnish gold or other metals and materials. Burnishing is the
process of moving or drawing a surface of metal to a greater depth. If a round steel point
is rubbed over a margin of a gold alloy inlay, the metal may be moved so that any small
discrepancy between the restoration and the tooth is closed. This action will finish (even)
the margins of restorations.
(2) Knives. Knives may be used to finish the margins of restorations. Black
number 8 is in common use.
