About this study

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

Inclusion criteria

  • above 20 years
  • ridge height less than or equal to 5 mm

  • disease or pathology within the sinus

Treatment and study plan

sinus lifting using CAD/CAM allogenic block

Procedure

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.
