The purpose of this present study was to investigate the effect of autogenous bone with histological evaluation of regenerated bone after sinus elevation. The study involved genaral healthy 6 patients participated in this study and were treated with 2-stage sinus elevation procedures using a combination of demineralized freezed-dried bone allograft (DFDBA) and coralline calcium carbonate with or without autogenous bone. At 6months after sinus elevation, bone specimens were obtained and stained with Hematoxylin-Eosin for light microscopic evaluation. The results of this study were as follows : 1. Autogenous bone grafts present trabecular patterns at 6 months in test groups, consist of woven bone and lamellar bone, but more compact than control groups. 2. Resorption of bone graft particles, osteoblast-like cells, newly formed osteoid tissue were observed at 6 months in test groups, but seems to be more frequently than control groups. 3. New osteoid tissue was formed from the surface of graft materials and gradually expanded around them. 4. The appearance of connective tissue around graft materials was densely formed, but more prominent in test groups than control groups. 5. Bone graft particles were resorbed incompletely and slight inflammatory infiltrate, newly formed capillaries, and adipocytes were observed. From the above results, autogenous bone is effective in bone regeneration after sinus elevation, could provide favorable conditions in implant placement.
