A concave working end is used where the operator wants to lift the sinus floor through the osteotomy or to compact soft bone, because the cupped tip carries bone upward rather than ahead of it. Being straight, it is the pattern for anterior sites and open access. At Ø 2.8 / 3.3 mm it is a mid-sequence size, following the narrower osteotomes; the colorless / yellow mark pairs it with Ø 3.3 / 3.8 mm implants.
