Abstract
A disposable right angle dental handpiece comprises a disposable plastic outer housing having an elongated opening therein for receiving a drive shaft mechanism which is preferably made of metal. The drive shaft mechanism is connected to the disposable outer plastic housing by means of a quick connect-quick disconnect mechanism. The outer housing also contains a gear which is engaged with a gear at the end of the drive shaft mechanism, a working member being connected to the gear for being driven by the drive shaft member. The drive shaft member is connectable to the dental tool for being driven thereby. Also disclosed are embodiments wherein the drive shaft mechanism is connected to the dental drive tool, and wherein the outer housing is independently connected to the dental drive tool by means of a quick connect-quick disconnect mechanism, which locks the outer housing relative to the dental drive tool in both the longitudinal and circumferential directions.
