Abstract

Objective:To compare the effectiveness of Dimineralised Bone Matrix (Osseograft) and Bio-Oss in preserving alveolar ridge dimensions following tooth extraction, using Cone Beam Computed Tomography (CBCT). Materials and Methods: This randomized controlled trial included 30 extraction sockets. 20 Participants were randomized into two groups: the Osseograft group and the Bio-Oss group. Following Atraumatic extraction, the respective graft material was placed in the socket. Immediately after extraction, socket dimensions were measured both bucco-lingually and mesio-dismally and then CBCT scans were conducted 3 months post-extraction. The primary outcomes measured were changes in socket dimensions and horizontal bone width. Results:Bio-Oss group showed statistically significant gains in both bucco-lingual (0.54 ± 0.20 mm) and mesiodistal (0.38 ± 0.15 mm) dimensions (p < 0.001), while Osseograft showed minimal change, significant only in mesio-distal width (p = 0.033). Conclusion: Bio-Oss showed superior performance in maintaining alveolar ridge dimensions compared to Osseograft, suggesting it may be a more effective material for socket preservation. Further studies with larger sample sizes and longer follow-up periods are recommended to validate these
