Abstract
A high speed dental handpiece (1) of the present invention includes a metal non-disposable body (3) and a plastic disposable cartridge (5, 5', 205, 205', 305, 605) received in the body (3). The body (3) is a one-piece body, has a sleeve (7), and an annular head (9) at an end of the sleeve (7). The sleeve (7) carries an air input line (27), an air exhaust path, a water line (25), and a fiber optic cable (29). The air input and water line (27, 25) are operatively connected to a supply of air and water, respectively. The fiber optic cable (29) is operatively connected to a source of light to carry the light to a patient's mouth to enable a dentist to more clearly see what is being operated upon. The disposable cartridge carries a turbine (95, 401, 501) and is placed in communication with the air input line (27) to drive the turbine. A bit (DB) is received by the turbine (95, 401, 501) and the water is directed toward the bit for cooling.
