Munce Discovery Burs

Munce Discovery Burs, available from CJM Engineering, feature round carbide heads on 31 mm (Shallow Trougher) and 34 mm (Deep Trougher) non-flexible shafts that facilitate positive troughing control for locating separated instruments and uncovering hidden canals.

These longer-than-standard-length burs draw the handpiece head away from tooth structure creating the favorable geometry that opens a functional view corridor to the deep target area. In contrast to standard shaft diameters of 2.4 mm, the narrow shafts of Munce Discovery Burs — 0.7 mm on the three smallest head sizes and 1.0 mm on all other head sizes — prevents shaft impingement on deep access cavity walls, significantly reducing ledging and perforation risk while preserving shaft stiffness.

In addition, the 0.7 mm shaft on the smallest head sizes allows parallel cement-line dissection around posts, post core-out procedures and offers visibility of the tiny heads in deep operations, visibility otherwise blocked by standard-diameter shafts.
