Brief Summary
28 patients will be included in this study with atrophic posterior maxillary ridge due to sinus pneumatization who will 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 graftthrough lateral window technique

Interventions
A full-thickness, wide mucoperiosteal flap was elevated buccally. A lateral bony window of the maxillary sinus will be made, then the sinus lining will be carefully elevated. 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). • The lateral window will be covered with collagen membrane, the flap will be repositioned in its place and sutured.
In group II the particulate bone will packed at the site of augmentation
