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

Exclusion Criteria:
sinus lifting using CAD/CAM allogenic block through lateral window technique
Procedure: sinus lifting using CAD/CAM allogenic block
sinus lifting using particulate allogenic graft through lateral window technique
Procedure: sinus lifting using particulate allogenic graft
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
bone height gain
using CBCT
Time frame: 6 months
marginal bone resorption around implants
CBCT
Time frame: 6 months
