Purpose: The aim of this study was to evaluate the effect of collagenated heterologous bone graft (CHBG) and Ankaferd Blood Stopper (ABS), a plant extract, on bone healing after sinus floor augmentation. Materials and Methods: Thirty-six New Zealand rabbits were used. Bilateral sinus augmentation was performed, and 72 bone defects were created. The maxillary sinuses were grafted with four different biomaterials: blood clot (control group), CHBG (Apatos Mix, OsteoBiol, Tecnoss) (graft group), ABS (ABS group), and ABS + CHBG (ABS+graft group). The rabbits were sacrificed at 1, 4, and 8 weeks after surgery. Histochemical and immunohistochemical examinations were performed on all samples. Staining with hematoxylin-eosin and Masson trichrome was performed, and bone marker activity was evaluated. Results: Lymphocyte infiltration was high at the first week in all groups and decreased from 1 to 8 weeks. All materials were biocompatible. Osteoclast numbers increased in the control group from 1 to 8 weeks and decreased in the other groups. There was no new bone formation in week 1 in all groups. New bone formation increased in all groups from 1 to 8 weeks, and at the fourth week, new bone formation was greater in the ABS and ABS+graft groups than in the other groups. There were osteoclasts around the bone graft materials, but degeneration of the graft was seen only in the ABS+graft group at week 8. Conclusion: ABS accelerates bone healing in sinus augmentation procedures and can be used alone or with CHBG. CHBG has osteoconductive properties, and ABS can accelerate bone graft degeneration.
