Abstract:

A prophy angle comprising a body, a drive system, and a paste feed assembly. The body includes a cylinder and a head portion associated with the cylinder. The drive system extends through the body and includes a drive shaft assembly and a cup shaft assembly. The drive shaft assembly extends through the cylinder. The cup shaft assembly extends through the head portion. The cup shaft assembly is coupled to the drive shaft assembly and further includes a prophy cup disposed at one end thereof. The prophy cup is in fluid communication with the body. The paste feed assembly includes a piston assembly and a piston movement assembly. The piston movement assembly includes a handle member. The handle member includes a second end associated with the piston assembly, a first end distally spaced therefrom and a pivot point positioned therebetween. Rotation of the first end of the handle member about the pivot point rotates the second end, moving the piston assembly relative to the body, to, in turn, direct paste positioned within the body to the prophy cup.
