Description of the Appliance

This air polisher is a compact water jet, air, and powder dental device used in the dental sector for prophylaxis and tooth polishing treatments. This air polisher can be used with powders of various particle sizes and guarantees a constant, efficient jet of powder and simple, reliable use. The operating principle of a air polisher is based on the mechanical action obtained by a mechanical jet of powders accelerated by a flow of compressed air. The kinetic energy thus impressed on the

1.2.1

particles is dissipated when it hits the enamel surface, thus producing a delicate but efficient polishing action. The action is completed by a jet of water which, by means of the vacuum created around the nozzle, forms a bell-shape around the main flow, thus producing a double effect: to prevent much of the rebound and the leakage of the powder jet and continuously wash the treated area, dissolving the powder itself. This air polisher can be supplied with different quick couplings for connection to the turbine of the dental unit.

Eligible Patient Group

This medical device is designed to be used with the following patient groups: •

Children;

•

Adults;

• •
