Abstract
An improved dental handpiece arrangement utilizes a drive cartridge containing the drive motor. The drive cartridge coacts with a coupling member and can be utilized with either a tubular adapter which enables use with one type of dental grip piece or can be utilized with a grip piece having an integral tubular portion for receiving the cartridge. The arrangement with the motor cartridge provides a great flexibility of utilizing grip pieces of different constructions.
