ABSTRACT:
The sleeve has a cylindrical metal tube with a plastic core. The metal tube has one or more grooves on the inner surface of the tube that run along at least a portion of the length of the tube. The plastic core fills the annular space between the metal tube and the rod of a rotary dental instrument, such that plastic material (1) fills the grooves to anchor the plastic core to the metal sleeve and (2) is molded to rigidly link the rod to the sleeve. The present invention reduces the exposure of plastic material in the sleeve, thereby reducing plastic swelling that can occur when the dental instrument is repeatedly cleaned using disinfectants.
