Osseodensification with Densah burs: thoughts?

Last Updated March 27, 2017

Anyone using the Densah bur series (Versah) to densify bone, lift the sinus or expand a ridge? I am considering trying this but I wanted to get feedback from those of you who have already used this. Please leave comments below.

Editor’s Note: Below are links to 2 studies on Osseodensification: - A Novel Osseous Densification Approach in Implant Osteotomy Preparation to Increase Biomechanical Primary Stability, Bone Mineral Density, and Bone-to-Implant Contact. Int J Oral Maxillofac Implants. 2017 Jan/Feb;32(1):27-36, Huwais S et al.

This study confirmed the hypothesis that the osseous densification technique would increase primary stability, bone mineral density, and the percentage of bone at the implant surface compared with drilling. By preserving bulk bone, it is hypothesized that the healing process will be accelerated due to the bone matrix, cells, and biochemicals that are maintained in situ and autografted along the surface of the osteotomy site. The healing response requires further study in vivo.

    Six weeks after surgery, new bone formation along with remodeling sites was observed for all groups. Bone chips in proximity with the implants were seldom observed in the R-drilling (regular) group, but commonly observed in the CW (clockwise osseodensification), and more frequently under the CCW (counter-clockwise osseodensification) osseodensification technique. In low-density bone, endosteal implants present higher insertion torque levels when placed in osseodensification drilling sites, with no osseointegration impairment compared to standard subtractive drilling methods.
