Background: Anorganic bovine bone (Bio-Oss®) has been extensively used for reconstruction of posterior area of
maxilla in sinus lift procedure; however, a new graft material (Lumina-Bone Porous®), that has a different
manufacturing process, has not been yet compared in clinical and histological terms. The manufacturing process of
bovine bone graft is related to size and porosity of the particles, and this can change osteoconductive property of
the material and bone formation. The use of Lumina-Porus® could improve bone formation, reduce the remaining
particles of the biomaterial using a low-cost material. The aim of this research was to compare the clinical,
radiological, and histomorphometrical results from maxillary sinus lift with two different anorganic bovine bone
substitutes Bio-Oss® (control) and Lumina-Bone Porous® (test).

Conclusion: Both materials Bio-Oss® and Lumina-Bone Porous® can be used in the maxillary sinus floor
augmentation with good predictability in clinical, radiographical, and histological point of view.
