Background: This study investigated the effect of Densah Burs on the primary and secondary implant stability, in addition to
periimplant mean marginal bone loss in maxillary implant supported partial overdentures.
Materials and Methods: Ten patients with posteriorly edentulous maxillae following kennedy class I classification were
selected. Each patient received two implants; one in each side. On one side, the implant osteotomy was prepared using
conventional surgical drills while on the other side, Densah burs were used. Implant stability was measured at implant insertion
and time of loading using Osstell device. Mean margial bone loss was measured at 6 and 12 month interval using Cone Beam
CT scan.
Results: Statistical Significant difference was noted between both types of drills on primary implant stability but not on
secondary implant stability or mean marginal bone loss at 6 and 12 month interval.
Conclusion: Densah drilling Burs may improve initial implant stability; a situation that may help when immediate loading of
implants is planned especially if they are splinted. Moreover, they might not have a different effect rather than conventional
drilling burs on marginal bone loss.
