ABSTRACT:
A dental handpiece comprises a handle section and a detachable head section. The head section to which a burr is mounted is made entirely of plastic except for ball bearings so that vibrations are absorbed via its own elasticity. The head section is disposed after use, thus avoiding the secondary infections of, for example, AIDS and hepatitis.
