This study compared the onset of vascular bleeding between osseodensification and conventional drilling of implant osteotomy sites. Patients requiring a single missing tooth replacement with type III trabecular bone were included and allocated to either group A (test) or B (control). In group A, osseodensification group (OD), implant osteotomy was carried out using Densah burs in counter-clockwise (CCW) direction, while for group B (standard drilling group) (SD) Densah burs were run in clockwise direction. An endoscope was introduced into the osteotomy, to visualize and measure time taken for initiation of bleeding (BI) and for blood to fill the osteotomy site (BF). A total of 40 osteotomy sites (23 maxilla, 17 mandible) were included in this cross-sectional study. The mean age of study participants was 50.1 year s± 8.28 years. The mean BI time for groups A and B was 18.54 ± 2.48 seconds and 16.89 ± 1.92 seconds respectively (p = 0.02); while the mean BF time for groups A and B was 41.92 ± 3.19 seconds and 37.95 ± 2.73 seconds respectively (p<0.001). Osseodensification does not seem to negatively affect or induce loss of vascularity of the bone. Clinicians should keep in mind that osseodensified sites might take slightly longer to be filled with blood following osteotomy. Int J Periodontics Restorative Dent. doi: 10.11607/prd.6542
