The Effect of Osseodensification Technique on Primary Stability of Dental Implants

Abstract

Purpose: To evaluate the primary and secondary stability when using densah bur in comparison to conventional drilling technique. Methodology: This experimental study was conducted on four dogs using split-mouth fashion so that each side will receive two implants with two different implant-site preparation techniques. In the study group, Densah Bur was used to osseodesify the osteotomy site where conventional cutting drills were used in the control group. The Peak Insertion Torque was used as an evaluation method of primary stability while the Resonance Frequency Analysis was used for both primary and secondary stability. Results: In this study, we collected our measurements via two methods. First, regarding the Peak Insertion Torque, the primary stability was (41 ± 1.2) in the study group, while in the control group, it was (35 ± 1.3) which reveals that the primary stability of the Densah Bur group outweighs the control group with a P-value of (0.003). Second, concerning the Resonance Frequency Analysis, the primary stability of the study group was (85 ± 2.2) while in the control group, the result was (75 ± 1.16) and the P-value of this test (0.0012). On the other hand, the secondary stability was measured by the same device and revealed (85 ± 3.5) of the study group while it shows (71 ± 3.17) in the control group with a P-value of (0.005). Conclusion: From the resulted data, this study verified that the use of osseodensification technique would increase primary stability this could be attributed to the enhancement of bone quality and bone-implant contact by preserving the bulk of bone.
