Objectives: To evaluate the effect of osseodensification using Densah bur on the primary stability of mandibular implant overdenture. Materials and Methods: Ten completely edentulous patients were selected and two implants were inserted in the interforaminal region for each patient in a split mouth design; one implant with the conventional drilling system and one implant with the Densah bur drilling system. Implant primary stability was measured using Resonance Frequency Analysis by Osstell immediately after torqueing the implants and every two weeks for 2 months.
Results: No significant difference was found regarding Osstell values at all follow up appointments for both groups. Conclusions: comparable results for primary stability with and without osseodensification which still requires further investigation with longer follow up period.
