28 patients will be included in this study with atrophic posterior maxillary ridge due to sinus pneumatization who will randomly assigned to two groups
28patients will be included in this study with an atrophic posterior maxillary ridge due to sinus pneumatization, who will be randomly assigned to two groups
Group I: sinus lifting using CAD/CAM allogenic block through lateral window technique
Group II: sinus lifting using particulate allogenic graft through the lateral window technique
Surgical procedure: A full-thickness, wide mucoperiosteal flap was elevated buccally. Alateral bony window of the maxillary sinus will be made then the sinus lining will be elevated carefully. The CAD/CAM allogenic block will be inserted and fixed in its position via a titanium screw to the crest of maxillary ridge (group I). In group II the particulate bone will be packed at the site of augmentation
The lateral window will be covered with collagen membrane, the flap will reposited in its place and sutured.
6 months later, implants will be inserted
