Abstract
A dental instrument for sonic or ultrasonic treatment comprises a shank (1) to which a treatment section (2) is joined. The shank (1) and treatment section.(2) are made of matrix-bonded carbon fibers. The instrument can be machined out of a woven carbon fiber fabric or can be a compression molding or an injection molding. The mechanical properties of the instrument can be adjusted by varying the length of the carbon fibers.
