Introduction: Dental implants primary or initial stability originates from the engagement with the cortical bone mechanically, whereas the secondary stability signifies the stability biologically by means of osseointegration through the bone formation and remodeling from the cancellous bone. Osseodensification is an innovative biomechanical technique to prepare the site. It uses Densifying Burs to produce low plastic deformation owing to its non-removal densifying method of site preparation, which preserves the bone enhancing the host site. Objectives: To evaluate the osseodensification (OD) technique used in implant site preparation by using the newly designed burs (Densah burs), and its effect on enhancing implant primary and secondary stability. Material and Methods: Twenty dental implants were placed in ten patients; each patient received one implant using the new Osseodensification drilling technique and one implant using the conventional drilling technique in the posterior maxillary ridge. Osstell was used in measuring resonance frequency (ISQ-scale) which is used to determine the amount of implant stability. Results: The results showed a significant improvement in both primary and secondary stability using densah burs. Conclusions: Densah burs produce better bone quality around the implant than conventional drills, and therefore, there is an improvement in the primary and secondary stability. |
