Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Oral and Dental Medicine - Department of Oral and Maxillofacial Surgery Summary: Six patients (3 females 50 %, 3 males 50%, age range 41-56 years with a mean age of 48.2 years) with partially/fully edentulous maxillae and a total of 9 sinuses in need for restoration of 20 sinus approximating missing premolars/molars, with residual bone height category C and/or D (RBH {u2265} 4-6mm/ {u2265} 1-3mm) according to the Consensus Conference on Maxillary Sinus Elevation were included in this study. Patients were randomly divided into two groups: Group I (HA Group): Open sinus lift and bone augmentation using hydroxyapatite discs. Group II (SCPC Group): Open sinus lift and bone augmentation using silica{u2013}calcium phosphate nano-composite (SCPC) discs. Second stage surgery was conducted 4 months following sinus-grafting procedure where bone core biopsies were obtained by a crestal approach using a trephine drill to be processed for histological analysis. Data was collected from CBCTs obtained preoperative, immediate postoperative and 4 months postoperative for analysis of linear, density and volume measurements. Alloplasts as Hydroxyapatite (HA) and Silica Calcium-Phosphate Nanocomposite (SCPC) have demonstrated acceptable results as graft options for posterior maxillae through open sinus lift using lateral approach
