### 4. DEVICE DESCRIPTION

The AIR-FLOW MASTER STANDARD is an air-polishing unit containing an operating unit, air/water pressure powered handpiece cords, powder chambers, AIR-FLOW handpieces, prophylaxis powders, multifunction footpedal and connections for external water and air supply. The operating unit of the AIR-FLOW MASTER STANDARD regulates the water and air/powder flow and selection of the prophylaxis powder chamber (Working Mode). The multifunction footpedal controls the operation of the AIR-FLOW handpieces. Upon installation, the AIR-FLOW MASTER STANDARD operating unit is connected to the external water and air supply.

Prior to use, the prophylaxis powder is loaded into the powder chamber and the chamber fixed to the operating unit. The AIR-FLOW handpiece is inserted into the air pressure powered handpiece cord and a powder nozzle is attached to the end of the AIR-FLOW handpiece. The operating unit is switched on and the air/powder flow and the Working Mode are adjusted on the control panel. When the operating unit is switched on, the

{1}------------------------------------------------

powder chambers are under pressure. Air enters the powder chamber of the operating unit where it mixes with the prophylaxis powder. The air/powder mixture leaves the powder chamber and enters the handpiece cord. When the multifunction footpedal is pressed, the air pressure of the handpiece cord is activated and allows the air/powder mixture to be delivered to the AIR-FLOW handpiece for treatment. The air/powder mixture exits the distal end of the AIR-FLOW handpiece through the powder nozzle where it is enveloped by a water spray and directed onto the tooth surface.

## 5. INTENDED USE

The AIR-FLOW MASTER STANDARD is an air-polishing unit intended for use in the cleaning and polishing of teeth by the projection of water, air, and dental powders onto the tooth surface. The device removes dental plaque, soft deposits, and surface stains from pits, grooves, interproximal spaces, or smooth surfaces of teeth.

The device can also be used for the following cleaning procedures:

- . plaque removal for placement of sealants
- . surface preparation prior to bonding/cementation of inlays, onlays, crowns and veneers
- surface preparation prior to placing composite restorations .
- . effective plaque and stain removal for orthodontic patients
- . cleaning prior to bonding ortho brackets
- . cleaning implant fixture prior to loading
- stain removal for shade determination .
- . plaque removal prior to fluoride treatment
- . plaque and stain removal prior to whitening procedure

## 6. TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE

The overall design of the proposed AIR-FLOW MASTER STANDARD is identical to the design of the parent AIR-FLOW S2 described in K900709. Both devices include an operational unit, powder chambers, AIR-FLOW handpiece, and the prophylaxis powder. They both contain controls for delivery of the air/water/powder mixture and provide nozzles for delivery. Both of the devices allow for control of the powder/air mixture delivery via a footpedal.

{2}------------------------------------------------

The technical modifications made to the parent device to produce the AIR-FLOW MASTER STANDARD are limited to removal of the ultrasonic functionality, updating the design of the operating unit, AIR-FLOW handpiece, and powder chambers, and the addition of controlling software. In addition, the prophylaxis powder accessories available were expanded to include the AIR-FLOW Soft prophylaxis powder and expand the offerings in the previously-cleared AIR-FLOW Prophylaxis Powder product line.

The changes made to the parent device to produce the AIR-FLOW MASTER STANDARD are minor and do not represent modifications to the indications for use, operating principles, or the fundamental scientific technology of the device. Testing was conducted to confirm that the proposed AIR-FLOW MASTER STANDARD meets established performance specifications. Based on the above discussion and the comparison chart on the following page, EMS Electro Medical Systems S.A. believes that the proposed AIR-FLOW MASTER STANDARD is substantially equivalent to the parent air-polishing unit, AIR-FLOW S2 cleared for marketing in the U.S. (K900709).
