Aim of the study: The present study was carried out to compare the healing outcomes around immediately placed implants in fresh extraction sockets using either Xenograft or DFDBA (demineralized freeze dried bone allograft) as bone augmentation materials with guided bone regeneration barriers. Materials and methods: Twenty patients participated in this study, were divided into two groups, Group (1): included ten patients who received immediate post extraction implants with (DFDBA) as a bone augmentation material and a collagen barrier, Group (2): included ten patients who received immediate post extraction implants with Xenograft as a bone augmentation material and a collagen barrier, two-piece Maxi Z implants were used. Surgical procedures included, raising a mucoperiosteal flap, atraumatic extraction of the tooth, preparation of the osteotomy, placement of the implant, then the bone augmentation material was used to fill the peri-implant bony defect then covered by collagen membrane. Clinical records were obtained preoperatively and six months after implant placement. Results: All the 20 two-piece implants were successfully osseointegrated as revealed by clinical and radiographic examination with no statistically significant differences between the two groups. Conclusions: Immediate post extraction implant placement in fresh extraction socket using either DFDBA or Xenograft as bone augmentation materials together with a collagen barrier were highly successful treatment modalities without any significant difference between them.
