Reconstruction of Complicated Posterior Maxillary Bone Defects Using Recombinant Human Bone Morphogenetic Protein-2 with Hydroxyapatite and Fibrin Sealant

In cases of common alveolar bone deficiency in the posterior edentulous maxilla, dental implant treatment can proceed following the reconstruction of the defect through alveolar ridge augmentation and/or maxillary sinus floor augmentation, depending on the specific characteristics of the bone deficiency.However, reconstruction remains challenging in cases of extensive alveolar defects with large bone perforations.The author successfully managed these complicated posterior maxillary bone defects using recombinant human bone morphogenetic protein-2 with hydroxyapatite and fibrin sealant as carriers.This report presents two cases demonstrating the efficacy of this approach.
