Universal inserts accomplish debridement in most areas of the mouth. Curved inserts are also effective in debriding furcations, the CEJ between tight contacts, malpositioned teeth, and concave surfaces inaccessible with the universal tip. Elliptical tip motion allows the clinician to use all sides of the tip. Linear tip motion allows the clinician the use of two surfaces of the insert. Another important area of consideration is automatic tune equipment versus manual tuning.
Manual tune allows the clinician control of the frequency as well as amplitude of the tip vibration.
The addition of a power foot control allows the clinician instantaneous hands free changes in tip vibration. Finally, some ultrasonic units are capable of delivering antimicrobial irrigation. Studies prove that plaque removal is enhanced from the cavitational effect of the water lavage delivered by magnetostrictive equipment and the solution depth equals the penetration depth of the insert. The TONY RISO corporation in Miami can convert most automatic tuning scalers into Manually Tunable Units at a reasonable price. Click Here to visit their web site.
