Histological, Histomorphometric, and Radiographic Evaluation of a Sinus Augmentation With a New Bone Allograft: A Clinical Case Report

Purpose: This case report documents the histological, histomorphometric, and radiographic effects of a new, radiated-preserved bone allograft for sinus elevation procedures. Materials and Methods: This unique bone substitute differs from other forms of bone allograft processed through the standard cryo-preservation method. Histology from bone biopsy core samples revealed newly formed bone with a well-organized lamellar bone structure in general and remaining particles were observed in contact with surrounding newly formed bone. Results: Histomorphometric results demonstrated an average new, bone formation of 31.8%. Radiographic linear data demonstrated an 8.49% +/- 6.77% graft resorption from baseline to 6 months. Conclusion: The outcome of this report suggests that this bone allograft could be successfully used hi sinus lifting procedures. It encourages further research of this radiated-I.-Preserved bone allograft material in oral and maxillofacial reconstruction. (Implant Dent 2008; 17:430-438)
