Document Summary
Be able to list or recognize the three parts of a hand instrument. Hand instruments are used to assist in the refinement of cavity preparations, to place restorative materials, and to aid in finishing restorations. Formed by making 45 angle on the end of the blade. Identify the materials used for manufacturing hand instruments and the benefits/ drawbacks associated with them. Can be made from different types of steel, use determines type of alloy used. Brittle, susceptible to corrosion, causes problems with sterilization. Carbon steel instruments should never be placed in the flame. Stainless steel (was used primarily in non-cutting hand instruments such as amalgam condensers) Newer alloys incorporate chromium, carbon, and iron to maintain sharpness and resist corrosion. Must be sterilized by steam or dry heat between patients. Identify the components of the 3 and 4 numbered formulas, the instruments to which they apply, and what information each number is associated with.
