研究组 & 干预措施
ascending ramus group
- 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
干预措施: Atrophic maxillary alveolar ridge augmentation (Procedure)
