Intervention

Procedure:
• Guided Bone regeneration
After local anesthesia, a crestal incision will be performed followed by full-thickness mucoperiosteal flap elevation Flap advancement will be attained through periosteal scoring of the buccal; The resorbable collagen membrane (Bio Gide, Geistlich AG) will be trimmed to the defect size. Xenograft (Bio-Oss) together with scrapped autogenous bone will be mixed and placed at the surgical site. The membrane will positioned over the graft and tucked into the lingual flap. Patient allocation concealment will be broken and the patients will be randomly assigned into two groups Patients receiving horizontal bone augmentation with resorbable collagen membrane stabilized with no tacks. The first layer will be closed with horizontal mattress sutures placed 4 mm from the incision line, and single interrupted sutures are used to close the edges of the flap. Vertical incisions are closed using single interrupted sutures and mattress suture should remain in place for at least 2 to 3 weeks
