Interventional Model Description: Assessment of ascending ramus cortical plate for reconstruction of atrophic maxillary ridges versus chin cortical plates (Randomized clinical trial)
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: ascending ramus group<br>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 | Procedure: Atrophic maxillary alveolar ridge augmentation<br>* Autogenous bone blocks from chin and ascending ramus are obtained and used for reconstruction of atrophic maxillary ridges<br>|
