Comparative Histological Assessment of Osseodensification Implant Site Preparation Versus Conventional Drilling Technique

Abstract

Purpose: is to analyze histologically in a dog model how osseodensification (OD) implant site preparation method influence the bone area fraction (BAF), the bone implant contact (BIC) and bone mineral density (BMD) around dental implants compared to the conventional drilling method. Materials and Methods: this experimental study was conducted on four dogs using split mouth fashion so that each side received two implants with two different implant-site preparation technique. In the study group, Densah Burs were used to osseodensify the osteotomy site where conventional cutting drills were used in the control group. Light Microscope (LM) examination of HE-stained sections was used to evaluate BAF, while Scanning Electron Microscope (SEM) was used to evaluate BIC and BMD. Results:osseointegration was almost similar in the control and experimental groups examined by both LM and SEM. There was no statistically significant difference between both groups in BAF, BIC and BMD. Conclusion: it can be concluded that OD technique using Densah Bur didn’t show any significant difference in the BAF, BIC or BMD than the conventional drilling methods in the experimental duration used.
