Augmentation of Extraction Sockets – A Requisite for Future Rehabilitation

Purpose: In this prospective study, bone formation in human extraction sockets is augmented with bovinecancellous bone (Bio-Oss) and compared to bone formation in unaugmented extraction sockets. Methods: Twenty patients with bilateral extraction sockets were included in this study. After all 40 extractions, one socket was augmented using cancellous bovine bone and another socket left to heal naturally. Bone density was measured by means of histogram, after 1 week, 1 month & 3 months following extractions. Results: Extraction sites with graft by the means of histogram showed significant difference in the bone density. They were significantly augmented as compared to the sockets without graft. Conclusion: The results of the present study suggests that the use of bone xenograft as graft material for alveolar ridge preservation after extraction. This aids in future rehabilitation with implant placement or fixed prosthesis.
