Alveolar Cleft Clinical Trial
Official title:
Xenografts With Platelet-rich Fibrin Versus Autogenous Bone in Alveolar Cleft Grafting: A Comparative Clinical Study
this work aims to evaluate xenografts mixed with PRF versus autogenous bone graft in alveolar cleft grafting.
The alveolar cleft is a maxillary bone defect resulting from incomplete fusion of the medial nasal process (MNP) and maxillary process (MXP) during embryonic development. Alveoloplasty may be classified as primary, secondary, and tertiary depending on the age of the patient. Literature defines primary when the alveoloplasty is performed at the same time as soft tissue repair. If performed at the age of 8 to 9 years before the eruption of the permanent canine, it is classified as secondary; it is classified as late secondary or tertiary if performed in the elderly. For patients with cleft lip and palate, secondary alveolar bone grafting (SABG) of the cleft alveolar ridge is performed when the patient has mixed dentition; SABG is a procedure that aims to create a bony bridge that restores dental arch continuity, repair the oronasal fistula, provide support to the structure of the alar base, facilitate subsequent orthodontic treatment, and promote tooth eruption. Autologous bone grafting is the gold standard for treating alveolar clefts, with the iliac crest bone being the most widely accepted donor site. Other materials such as growth factors, combinations of improved scaffolds and cell treatment/growth factors, biocomposites, and hemostatic agents can be used to regenerate bone and have been the subjects of intensive research. ;
