Abstract :Maxillary sinus and ridge augmentation were performed using the allograft cellular matrix containing live stem cells (Osteocel)*. The results were evaluated via a postoperative Cone Beam Computer Tomography (CBCT) scans and periepical radiographs. The sinus augmentation case was evaluated in 10 weeks in which the radiographic bone tomography was similar to that of the native bone. The ridge augmentation case resulted in a 3-4 mm vertical ridge augmentation. Even though histological examination was lacking, the clinical and radiographic feel of the cases were promising. This presentation will show the clinical and radiographic documentation of both cases in addition to discussing the potential benefits of stem cell bone matrix with its future promises.
