AIR ABRASION 2

AIR ABRASION
ADVANTAGE

Pain during tooth structure removal is eliminated or at least reduced.

No vibration occurs during Air abrasion procedure

The only noise produced by Air abrasion is a familiar vacuum cleaner sound.

Well-designed tips provide good control during the procedure.

Patients who are afraid of traditional dentist techniques and the noise of airrotor handpieces can be treated, without anesthesia, using air abrasion.

It adapts well to Class I, IV and V preparations.

It is an especially useful technique for children.

Used properly, air abrasion "explores" incipient carious lesions extremely well, often locating carious areas previously undetectable visually or by radiography.

DISADVANTAGE

Air abrasion technique is not familiar,period to accustom themselves so dentists require a learning to it.

Tooth preparations do not resemble traditional, precise, clearly identifiable outlines.

The practitioner's tactile perception during tooth structure removal is minimal.

At this time, only small tooth preparations can be accomplished with the Air abrasion technique.

Expertise is required to control it by proper direction of the Air abrasion handpiece tip, excellent suction and, potentially, by use of air filtration devices.

The practitioner's vision is sometimes obscured by debris while tooth structure is being removed.

Performing air abrasion on Class II and III areas requires more extensive learning than that required for using the technique on other tooth locations.

Old amalgam cannot be removed produce mercury dust.

It doesnot remove soft decay bcoz the particles are absorbed to remove the soft decay one should use slow hand piece with no.2 or no.4 round bur or sharp spoon

Crown preparations are not possible with Air abrasion .

Aluminum oxide debris accumulates everywhere.
