Chisel and mallet
One of the obvious methods of bone removal is to use a surgical chisel and mallet (Fig. 11·17, A-C). Bone is usually removed with a monobevel chisel, and-teeth are usually sectioned with a bibevel chisel. The success of chisel use depends on the sharpness of the instrument. Therefore it is necessary to sharpen the chisel before it is sterilized for the next patient. Some chisels have carbide tips and can be used more than once between sharpenings. A mallet with a nylon facing imparts less shock to the patient is less noisy and is therefore recommended.
