What is Freeze‐dried homogeneous and heterogeneous bone for sinus augmentation in sheep: Part I: Histological findings about?

**Abstract:** Freeze‐dried bone has been reported to possess an osteogenetic potential, i.e. to be osteo‐inductive or osteoconductive depending on the grafted site. In this animal study homogeneous demineralized freeze‐dried bone from the sheep (s‐DFDB) and heterogeneous human demineralized freeze‐dried bone (h‐DFDB) used for single‐stage sinus elevation were examined for their potential to improve bone‐to‐implant bonding. In 72 sinuses of 36 adult female mountain sheep Schneider's membrane was elevated from the local bone through an extra‐oral approach and two cylindrical plasma‐flame sprayed titanium implants were inserted in the lateral wall of each sinus. At the same time 18 sinuses were reinforced with s‐DFDB, another 18 with h‐DFDB and yet another 18 with autogenous cancellous bone from the iliac crest. In 18 animals the subantral space remained ungrafted. At each follow‐up date, i.e. at 12, 16 and 26 weeks, 12 animals were re‐examined and one randomly selected implant from each sinus was analyzed histologically and histomorphometrically. With both s‐DFDB and h‐DFDB extensive fragmentation and disintegration were seen side by side with sporadic areas of remineralization. Thes
