The present study is a randomized clinical trial conducted on 17 patients to evaluate bone height gain, bone density (grey scale) values and implant stability after maxillary sinus floor elevation using graftless tenting technique or augmentation using deproteinized bone graft with simultaneous implant placement. Computer guided lateral window sinus floor elevation was the technique used in both groups.All patients were followed up clinically and radiographically for 6 months. Radiographic evaluation involved cone beam CT one week and six months postoperatively to evaluate bone height gain, bone density changes. Resonance frequency analysis to measure implant stability using Osstell device was performed immediately after implant insertion and six months postoperative at time of implant exposure.Statistical analysis of the results showed significant difference between the two groups in the three studied parameters in favor of deproteinized bovine bone. However, both techniques are considered acceptable treatment options for successful implant placement in atrophic posterior maxilla
