Tools of the trade: IM3 42-12 ultrasonic scaler

by Dr Lisa Woollard, The Blackburn Vet, VIC

We recently acquired the new iM3 42-12 ultrasonic scaler and are quite impressed with its performance. It removes calculus with ease and comes with two interchangeable tips—a universal tip and a perio tip.

What’s good about it

Some older scalers are operated by a foot pedal but this scaler uses a finger on/off power control on the handpiece. It also allows both CLS and water to flow freely onto the tip. The scaler tips insert and remove easily from the handpiece without any twisting which means they can’t break off in the handpiece. They are also autoclavable. The iM3 scaler works at a much higher frequency than other units so you can remove thick calculus rapidly, reducing anaesthetic times. This unit is very gentle compared to others and causes much less damage to the tooth enamel. It’s also safe to use beneath the gumline.

What’s not so good

The handpiece isn’t very ergonomically designed and is a little cumbersome to use.

I’m yet to find a happy medium with the coolant flow through the scaler. When turned down, the coolant doesn’t hit the tip and it heats up. When turned up, there is too much water in the mouth.

Finally, it would be great if there was a bracket for the handpiece to attach directly to the scaling unit. At present, it has a separate bracket that just has a non-slip mat underneath. It has the potential to be knocked onto the floor.
