A randomized clinical trial aims to evaluate the clinical and radiographic outcomes of the repair of congenital alveolar clefts using Iliac crest graft with and without mixing with platelet-rich fibrin
Alveolar clefts occur in response to deviations from normal development in the growth, exposure, and fusion of the frontal eminence. The most common alveolar portion of the cleft is located between the central incisors and canines. The treatment of alveolar clefts is multidisciplinary and aimed at restoring normal ridge contour and functionality. Surgical wound closure is insufficient to repair bony defects, Additional materials are needed for these types of defects, such as bone grafts. Aim: The aim of this study is to evaluate the efficiency of using iliac crest bone graft with and without platelet-rich fibrin in repair of alveolar clefts. Methodology: This study will be conducted on 16 patients with alveolar clefts. The patients will be divided equally and randomly into 2 groups: Group 1 : 8 patients will be treated with iliac crest bone graft only (control group).Group 2: 8 patients will be treated with iliac crest bone graft with platelet-rich fibrin (study group).
297 studies on the registry are indexed under Alveolar Bone Loss; 76 are open to participants now.
This study's enrollment of 16 is below the median of 25 across 254 interventional studies indexed under Alveolar Bone Loss.

Exclusion Criteria:
study group: the patients will be treated with iliac crest bone graft with platelet-rich fibrin
Procedure: alveolar bone grafting Plus Platelet rich fibrin
control group : the patients will be treated with iliac crest bone graft only
Procedure: alveolar bone grafting
cancellous iliac crest bone will be harvested following the usual surgical procedure. For patients of group a-PRF, it was mixed with 1 cc of the supernatant previously collected, in order to obtain a cohesive bone graft, easier to manipulate. The oral mucosal lining will be closed, and a membrane of PRF (PRF group) will be put over the suture line. The alveolar cleft will be then filled with cancellous iliac crest bone along its entire height. A new membrane of PRF will be placed over the bone graft, in order to enclose and protect it. Finally, muco-periosteal flaps will be advanced and sutured without tension over the alveolar crest

the PRF group: centrifugation at 1300 rpm during 5 minutes, collection of 1 cc of the supernatant, and centrifugation at 1300 rpm during 3 minutes. Careful removal of the clot and separation from the red blood cell fraction with scissors. the Platelet-rich fibrin will be added to the surgical site mixed with the iliac crest bone graft and it will also be used as a membrane before closure of the mucoperiosteal flap

Changes in bucco-lingual thickness of the bone at the recipient site
Post-operative cone beam computed tomographic radiographs will be done using the Scanora 3DX imaging system using a CMOS flat panel detector with isotropic voxel size 133 µm. The x-ray tube that is used to scan the patients possesses a current intensity of 10 mA, 90 KVp, and a focal spot size of 0.5 mm. The scanning time is 14 seconds of pulsed exposure, resulting in an effective exposure time of 3.2 seconds to scan FOV (field of view) of 14 cm height × 16.5 cm width. The raw DICOM data set images will be imported to the On-Demand software (Cybermed, Seoul, Korea) for secondary reconstruction and image analysis. CBCT will be performed, and linear measurements will be obtained in axial, sagittal, and coronal cuts to assess the changes in buccolingual thickness of the bone at the recipient site 3 months and 6 months post-operatively.
Time frame: 3 months and 6 months postoperatively
Calculation of the volume of bone fill in the recipient site
The volume of remaining alveolar defect around the bone graft at 6 months will be measured and subtracted from the actual alveolar defect volume to calculate the volume of bone fill. The actual volume of alveolar bone graft will be represented as a percentage of bone fill of the alveolar defect volume (Preoperative alveolar Defect Volume minus Postoperative residual defect volume / Preoperative Alveolar defect volume X 100)
Time frame: 6 months postoperative
wound dehiscence
Clinical evaluation for wound dehiscence immediate, 7 days, and 14 days postoperatively to detect any complications such as infection, flap dehiscence, or fistula formation. Then the percentage of cases with soft tissue complications will be calculated
Time frame: immediate, 7 days and 14 days postoperative
