Densah bur technology is based on the newest biomechanical technique of bone preparation called “osteodensification”. Unlike traditional techniques of drilling used in dentistry during “osteodensification” bone tissue is not cut out. Instead, it is simultaneously compressed and autografted in the directions expanding outside from the osteotomy hole.
In the process of high-speed rotation of the Densah bur while cutting in reverse motion and constant external irrigation of the walls and floor of the osteotomy hole solid compact layer of bone tissue is formed.

Traditional twist drills or parallel grooved drills have 2-4 facets, which help the burs move down the osteotomy hole. Densah burs have 4 facets or more, and it makes the advance through the bone very precise. The more facets, the less vibration.
During osteodensification Densah burs subject the bone to controlled plastic deformation, which allows to create cylindrical osteotomy hole avoiding cutting out bone tissue.
