The convex tip compresses and widens the osteotomy walls laterally, which is the geometry used for ridge expansion and bone condensing before implant placement. The angled shank is for posterior sites, where a straight instrument cannot be aligned with the osteotomy without the mallet hitting the opposing teeth. At Ø 3.4 / 3.8 mm it is a mid-sequence size, following the narrower osteotomes; the red mark pairs it with Ø 4.3 mm implants.
