Media – 29/53 micron Aluminium Oxide (blue/red container).
Nozzle – 0.6mm diameter or 0.8mm diameter.
Power – 4 bar.
Media Flow – Slightly under midway position.
The enamel of the tooth to be treated can be “etched” to the exact size of the orthodontic bracket at the place of attachment.
This is achieved by holding the cutting nozzle 2mm above the surface of the tooth and gently moving it in a circular motion over the required area. This will result in a dry “etched” surface, ready to accept the bonding agent, and the risk of saliva contamination is greatly reduced because the aluminium oxide dries the surrounding mucosa.
The same technique can be used to clean the orthodontic brackets.
