Arm && Interventions

Group	Intervention	Description
ascending ramus group	Atrophic maxillary alveolar ridge augmentation	* Local anesthesia will be given to the patient * flap will be reflected to expose the facial wall of the maxilla then The ascending ramus is accessed. * A disc bur will be used to make a rectangular osteotomy * The block bone graft is removed from ascending ramus to recipient site the fixed by mini screws * Doner site flap is closed by using interrupted internal sutures. * after atrophic maxillary alveolar ridge augmentation,sub mucosal periosteal releasing cuts is done * Post-operative medications will be prescribed as follows: amoxicillin/clavulanic acid tablets 10mg/kg every 12 hours for 7 days, metronidazole 5 mg/kg every 8 hours for 7 days
Chin Group	Atrophic maxillary alveolar ridge augmentation	* Local anesthesia will be given to the patient * flap will be reflected to expose the facial wall of the maxilla then The chin is accessed. * A disc bur will be used to make a rectangular osteotomy * The block bone graft is removed from chin to recipient site the fixed by mini screws * Doner site flap is closed by using interrupted internal sutures * after atrophic maxillary alveolar ridge augmentation,submucosal periosteal releasing cuts is done * Post-operative medications will be prescribed as follows: amoxicillin/clavulanic acid tablets 10mg/kg every 12 hours for 7 days, metronidazole 5 mg/kg every 8 hours for 7days
