ABSTRACT:
The present invention provides a handpiece for dental medical treatment in which a head portion encasing therein an air turbine is detachably mounted on a handpiece body whereby the handpiece body capable of being subjected to high temperature sterilization by boiling is repeatedly used whereas the head portion is discarded after use to maintain the aseptic state of the whole handpiece and positively prevent secondary infection such as AIDS, hepatitis, etc. in an actual medical site. Furthermore, the construction of the air turbine and molding of various parts are simplified so that the head portion can be provided at extremely low cost to effectively prevent infection of AIDS, hepatitis, etc. as mentioned above.
