The current study aims to compare the double mandibular corticocancellous bone blocks technique with mandibular cancellous bone particles in between versus the double iliac corticocancellous bone blocks technique with iliac cancellous bone particles in between in the tertiary cleft grafting to find out which technique maintained better graft width, height, and volume with the least adverse effects after the healing period and hence would allow for restoration of the targeted function and esthetics and improve the cleft patients psychologically and hence improve their quality of life.
patients with unilateral alveolar cleft who missed the mixed dentition phase window.
patients with previously repaired cleft lip and palate.
patients with proper oral hygiene.
Immunocompromised patients.
patients with active periodontitis.
patients with inadequate oral hygiene.
