The present study was performed to evaluate socket preservation using collagen sponge with autogenous dentin graft versus collagen sponge with de-mineralised freez-dried bone graft on dental implant stability
in our study we made socket preservation using two different grafts in two groups. before grafting we took CBCT we used autogenous dentin graft covered by collagen sponge in one group and demineralized freeze - dried allograft covered with collagen sponge in the other group. after 6 months we Took another CBCT to assist the dimensional changes and bone density in the alveolar socket after grafting We inserted the implant and during insertion we took a core biopsy with trephine bur with external diameter 3 mm for histological analysis. After implant insertion we assisted the stability using RFA.
