The invention is directed towards a handpiece assembly for use with air abrasion apparatuses used in a wide spectrum of applications and industries. This handpiece assembly comprises the following components: (1) a handle comprising a proximal end and a distal end; the distal end also comprising an attachment means for attaching the handle of the handpiece assembly to the air abrasion apparatus; (2) a quick-releasing and quick-connecting socket comprising a male portion and a female portion; and (3) a nozzle comprising a proximal end and a distal end; the distal end of the nozzle provides the male portion of the socket and the proximal end of the handle provides the female portion of the socket. The distal end of the nozzle also fits into the proximal end of the handle to form the quick-releasing and quick connecting socket. This novel handpiece assembly may further comprise an articulating socket located towards the proximal end of the nozzle. These features of the invention provide a handpiece where the nozzle can be quickly released or disconnected from, and reconnected to, the handle, thus providing facile exchange of nozzles of varying shapes and sizes, as needed to accomplish the a desired task. The invention also includes a kit for dental use comprising the handpiece, a dental mirror and a sterilizable tray for holding instruments.
