Alveolar Cleft Grafting by Double Iliac Bone Blocks Versus Iliac Spongy Bone From Anterior Iliac Crest

Not Applicable

• Conditions: Alveolar Cleft
• Interventions: Procedure: Grafting of the alveolar cleft

• Registration Number: NCT05283005
• Lead Sponsor: Cairo University

Brief Summary

Reconstruction of Alveolar Cleft Using Double Iliac Corticocancellous Blocks in comparison with the gold standard technique ( cancellous bone ) both from anterior iliac crest.

Detailed Description

This study will compare two techniques for the proper alveolar cleft reconstruction with adequate bone bridge formation of maximum bone quality, contour, and minimal resorption. One of them is packing autogenous particulate spongy bone from the anterior iliac crest (gold standard). While the other technique would be reconstruction of the cleft with two iliac corticocancellous bone blocks with cancellous bone in between. which benefits of the rapid revascularization and healing of cancellous bone and the strong mechanical properties of cortical bone that will aid in obtaining a proper reconstruction and form for the defect and can be applied to defects of any size.

Inclusion Criteria

• Patients with complete maxillary alveolar cleft either unilateral or bilateral at the age of mixed dentition (between 7 and 13 years old).

  • repaired cleft lip.
  • Patients with cleft lip and palate who have not undergone alveolar grafting procedure.
  • Patients with unerupted maxillary permanent canine in the cleft region.

Primary Outcome Measures

Name	Time	Method
Measuring graft height in millimeters	9 months	CBCT scan analysis for measuring mean graft height in millimeters of every graft of both groups of patients immediately after surgery and compare it with CBCT scan analysis for measuring mean graft height in millimeters after 9 months of every graft for assessment of grafts height stability of both groups over 9 months.
Measuring graft width in millimeters	9 months	CBCT scan analysis for measuring mean graft width in millimeters of every graft of both groups of patients immediately after surgery and compare it with CBCT scan analysis for measuring mean graft width in millimeters after 9 months of every graft for assessment of grafts width stability of both groups over 9 months.

Secondary Outcome Measures

Name	Time	Method
Measuring graft volume in cubic millimeter	9 months	CBCT scan analysis for measuring graft volume in cubic millimeter of every graft of both groups of patients immediately after surgery and compare it with CBCT scan analysis for measuring graft volume in cubic millimeter after 9 months of every graft for assessment of grafts volume stability of both groups over 9 months.
