ABSTRACT:
A sterilized protective sleeve in combination with a rigid shield for the handle of a dental instrument is disclosed wherein the sleeve consists of an elastic tubular casing adapted to conform to the shank of the instrument. The rigid shield is contoured to conform to the head end of the instrument and has an opening through which the rotating burr of the instrument protrudes. Furthermore, one of the open ends of the casing is capable of receiving or extending over both the rigid shield and the shank of the dental instrument so that the rotating burr extends out of the other open end of the casing. In particular, the opening in the rigid shield is made slightly larger than the shank of the burr so that minimal clearance is provided to minimize contamination.
