CLINICAL COMPARISON OF VASCULAR BLEEDING TIME CREEP BETWEEN OSSEODENSIFICATION AND CONVENTIONAL DRILLING OF IMPLANT OSTEOTOMY SITES.

This study focused on comparing vascular bleeding times between osseodensification (OD) and conventional drilling (standard drilling, SD) techniques during dental implant osteotomy in patients with type III trabecular bone. Using Densah Burs in counterclockwise rotation for OD and clockwise rotation for SD, the researchers measured the time to initial bleeding (BI) and time for blood to fill the osteotomy site (BF) via endoscopic visualization in 40 implant sites. Results showed that while BI times were slightly longer in the OD group, the difference was statistically significant but clinically minor; however, BF times were significantly longer in the OD group, possibly due to vessel occlusion by compacted bone. The study concluded that osseodensification does not adversely affect bone vascularity or vitality and that maxillary and mandibular sites respond differently to OD, suggesting clinicians should consider these differences when applying the technique.
