N2  - Patients with partially/fully edentulous posterior maxillae in need for prosthetic restoration of 20 sinus-approximating premolars/molars and deficient vertical alveolar bone height were included in this study. Patients were divided into 2 groups, group I (Control) Open sinus lift and bone augmentation using hydroxyapatite, group II (Study) Open sinus lift and bone augmentation using silica{u2013}calcium phosphate nanocomposite (SCPC). Core Bone Biopsy was taken 3-4months following sinus grafting procedure. Core bone biopsies was obtained using trephine burs at the designated sites of implant placement during the time of implant placement. In brief the evaluation parameters in this study included:Cone Beam Computerized Tomography (CBCT) (Pre-operative, 0 & 4months postoperatively) Scanning Electron Microscopy (SEM) (4months postoperatively)Histological study (4months postoperatively) The results achieved by the current study sample were in accordance with previous reports concerning the biocompatibility of both materials HA and SCPC as none of our histological specimens revealed otherwise. Both materials were partially substituted by new bone formation
