Pear Shaped Dental Burs

Pear shaped dental burs — rounded, dome-ended heads — are the conservative dentistry shape: minimal-extension access, amalgam and composite preparations with rounded internal line angles that resist stress concentration. This collection covers US numbers 330–333 and the long 331L–333L family in carbide and diamond.

The 330 in particular defines minimally invasive operative access, and Busch’s versions carry the smooth-running concentricity that keeps small pear heads precise at high speed.

FAQ

What is a 330 bur? The US No. 330 pear bur (Busch figure 7, size 008) — the classic conservative cavity access and preparation instrument.

Pear vs. round bur? The pear’s dome end and tapered sides cut a self-retentive, rounded-line-angle preparation in one shape; rounds excavate more freely in all directions.

Where are these burs made? Every instrument in this collection is manufactured by Busch & Co. in Engelskirchen, Germany — an ISO 13485-certified specialist in rotary precision instruments since 1905 — and ships fast from our US warehouse.
