Since its introduction in 1972, alveolar bone grafting (ABG) has been widely accepted to correct alveolar bone defect in most cleft centres.The purpose of ABG is to restore the dental arch continuity, stabilize the maxilla, close the oronasal fistulae, facilitate subsequent orthodontic treatment, enhance nasal symmetry, establish better oral hygiene, limit growth disturbances, etc . Autologous bone grafting is the gold standard for treating alveolar clefts, with the iliac crest , bone being the most widely accepted donor site(Tan, Brogan et al. 1996.New bone graft substitutes have been devised in recent decades, such as demineralized bone matrix (DBM), bone morphogenetic proteins (BMPs), calcium phosphate (CP), calcium sulfate (CS), hydroxyapatite (HA), highly purified bovine xenograft, and more, but clinical evidence of their efficacy varies among clinical and experimental studies \\[4\\] With the advent of new biomaterials, which may include or consist of allogenic bone source such as collagen membranes, hydroxyapatite crystals, tricalcium phosphate powder that has been increased consideration for their placement in the repair of alveolar clefts as well as other dental applications'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '12 Years', 'minimumAge': '7 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age (7 - 12 years )\n* Non-syndromic CLA or CLP\n* More than 6 months of follow-up\n\nExclusion Criteria:\n\n* History of previous alveolar surgery\n* History of active infection or underlying disease such as hematologic disorders , neoplasm, and immune deficiency\n* Patients who had received primary or tertiary ABG'}, 'identificationModule': {'nctId': 'NCT04693559', 'briefTitle': 'Assessment of Nanocrystalline Hydroxyapatite Versus Autogenous Bone Grafts : A Comparative Clinical Study in Alveolar Cleft Grafting', 'organization': {'class': 'OTHER', 'fullName': 'Assiut University'}, 'officialTitle': 'Assessment of Nanocrystalline Hydroxyapatite Versus Autogenous Bone Grafts : A Comparative Clinical Study in Alveolar Cleft Grafting', 'orgStudyIdInfo': {'id': 'AssiutU011270'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'OTHER', 'label': 'autogenous iliac bone graft (group A)', 'description': 'autogenous iliac bone graft will be used to fill the alveolar defect', 'interventionNames': ['Procedure: secondary alveolar bone graft', 'Procedure: harvesting of the autogenous bone graft']}, {'type': 'OTHER', 'label': 'Nano crystalline Hydroxyapatite (group B)', 'description': 'Nano crystalline Hydroxyapatite will be used to fill the alveolar defect', 'interventionNames': ['Procedure: secondary alveolar bone graft', 'Procedure: Nanocrystalline Hydroxyapatite']}], 'interventions': [{'name': 'secondary alveolar bone graft', 'type': 'PROCEDURE', 'description': 'Under general anaesthesia, the soft tissue in the gingiva surrounding the alveolar cleft will injected with 0.5% lidocaine with 1:100,000 parts of epinephrine.
