摘要：
A dental prophy angle which includes a separate rib for securing each of the drive assembly and a workpiece by a friction lock. Preferably this rib is circumferential and present in both the shank end and the head end of the prophy angle. Each rib of the friction lock will permit the workpiece or the drive assembly to pass by the rib and be inserted into the housing. However, the ribs will not permit the inserted workpiece or drive assembly to pass backwards over the rib and be withdrawn from the housing.
