DENTAL HANDPIECE

摘要

This invention relates generally to dental handpieces, and more particularly to dental handpieces for use in piezoelectric or magnetostrictive-driven dental sealers. In particular, the present invention is directed to a handpiece (10) for an ultrasonic dental instrument comprising a grip portion (12) positioned near a working end (11) of the handpiece, an intermediate portion (14) adjacent and aft of the grip portion, a mount portion (15) located aft of the intermediate portion for removably securing the handpiece to a tailpiece, and a receiver portion (17) for receiving a removably replaceable ultrasonic head instrument. The grip portion comprises a first surface property and the intermediate portion comprises a second surface property where the second surface property differs from the first surface property. The first surface property, for example, may be relatively supple as compared to the second surface property. The second surface property may be relatively smooth as compared to the first surface property.
