Evaluation of Surgical Bur Deformation and Bone Surface Roughness After Multiple Uses.

Purpose: The aim of the present in vitro study was to microscopically evaluate and describe the deformation of Lindeman surgical burs and the bone surface roughness after repeated osteotomies and sterilization cycles.

Materials And Methods: Twenty-one Lindeman surgical burs were analyzed under scanning electron microscopy (SEM) to evaluate the damage of the bur's integrity after 0, 1, 3, 5, 7, or 9 osteotomies on bovine ribs. Eighteen bone specimens were obtained after osteotomy for roughness analysis using profilometry.
