Sectional Bands are used on amalgam, composite, build-up, and temporary filling tray setups.
Classes III and IV composite restorations use a Clear Mylar Matrix strip.
Sectional Bands should be disposed of in Sharps container, or state regulations should be followed. Single use only. Tension Rings and forceps must be cleaned, bagged individually or bagged/wrapped in a tray setup, and then sterilized. A chemical/steam indicator device should be included in the wrapping. Hinged instruments should be processed open and unlocked.
