Osteocel Plus for Osteoporosis

The purpose of this study is to histologically and radiographically evaluate the maxillary sinus bone volume and density, with reference to percentage of vital bone present, after four months of grafting with either Osteocel or a cortical-cancellous allograft. 1. To assess the quality and quantity of the maxillary sinus bone prior to the placement of dental implants and subsequent restorations, approximately 20 patients will be randomly assigned to receive an augmentation of the maxillary sinus region using either Osteocel or a cortical-cancellous allograft. 2. With the use of pre-operative and four months post-operative CBCT radiography, the maxillary sinus bone density will be assessed and compared between the individuals receiving Osteocel and the individuals receiving conventional cortical-cancellous allograft material. 3. Histomorphometric analysis will be used to assess, compare and contrast the quality and the quantity of the new vital bone cells generated when using these different graft materials
