Abstract:

  Background and Aim: One of the most common problems after tooth extraction is alveolar bone resorbtion and in sufficient remaining bone for future implant insertion or appropriate denture fabrication to obtain adequate function and aesthetics. The aim of this study is to assess the effect of Ceno-bone (allograft) on reduction of alveolar bone resorption after tooth extraction.

  Materials and Methods : This research was rolled on 42 dental sockets in patients who were referred to oral and maxillofacial department of Shahed University during two years (2009-2011).The study design was split-mouth in which all sockets were divided in to case and control groups. Each socket was filled with Ceno-bone (FDBA) and sutured in case group and no material was added to the fresh sockets in control group.Follow-up radiographs were taken 1week, 2 months, and 6 months after surgical procedures. The results were statistically analyzed by pairedT- test.

  Results : Alveolar bone loss in case and control groups were (0.86±0.36) and (1.33±0.48). respectively . Six months after surgery and there was significantly differences between two groups (p<0.002). There was not any significant differences between two groups one week and two months after surgical procedures. (P>0.05)

  Conclusion : Ceno-bone allograft (FDBA) seems to be an appropriate material for filling bony defects and accelerates bone regeneration and decreases resorption in remaining alveolar bone after tooth extraction.
