BUC® 3 The Digger, 20.2mm

Obtura Spartan · BUC® ultrasonic tips

Troughing around posts and cutting into calcified canals

The BUC® 3 is what Obtura Spartan call an extremely active tip for cutting apically into calcified canals, 20.2mm long and diamond coated, with the water port moved back onto the shaft so the operative site is washed and cooled while you work.

Asked before buying

Will it fit my ultrasonic unit? Obtura Spartan make the range for scalers using M3 x 0.6 threading, and offer every tip again as the E series with M3 x 0.5. This one is M3 x 0.6. Check your unit's manual first – they warn that forcing a tip with the wrong thread damages the device. The tip wrench seats it properly.

How long does a tip last? Obtura Spartan state the tips were tested to 250 reprocessing cycles to ISO 18397 without loss of performance or corrosion – but end of life is set by wear in use as well, so inspect each tip during cleaning and retire damaged ones. They also ask for very light pressure: small-diameter tips are subject to breakage at any time.
