Abstract

Purpose The aim of this study is to evaluate the effect of dentin graft and autogenous bone graft on the maxillary socket preservation. Subjects and Methods Ten patients, who had un-restorable maxillary teeth, and had a plan for implant placement after extraction, were included in our study. They were divided based on the type of graft used in socket preservation into two equal groups; Group A: the extraction sockets in five patients were grafted with dentin graft and then covered with collagen membrane. Group B: the extraction sockets of the remaining five patients were grafted with autogenous bone graft before being covered with collagen membrane. CBCT was used to evaluate horizontal and vertical alveolar bone changes preoperatively and at 6 months postoperatively. Results There was no statistically significant difference in horizontal and vertical bone loss in both groups after 6 months, in both groups there is a dramatically decrease in post extraction bone loss. Conclusion The use of dentin graft resulted in similar clinical and radiographic outcomes compared with those obtained using autogenous bone graft thus overcoming the limitations of autogenous bone graft.
