6 details of dental handpiece maintenance

Under normal circumstances, the working pressure of two-hole and three-hole handpiece is 2-2.2Kg, and the working pressure of four-hole, five-hole , and six-hole handpiece is 2.4---2.5Kg (refers to the pressure at the interface between the handpiece and the connecting pipe). The pressure must be adjusted when the new treatment machine is used, and the pressure of the treatment machine must be re-calibrated after a period of use (about one month).
