Alveolar Cleft Reconstruction Using Different Grafting Techniques

Area of Science:

• Regenerative Medicine
• Oral and Maxillofacial Surgery
• Biomaterials Science

Background:

• Cleft lip and palate (CLP) is a common congenital anomaly requiring complex surgical management.
• Alveolar cleft grafting (ACG) aims to restore bony continuity for dental and facial symmetry.
• Grafting materials and techniques for ACG are still debated.

Purpose of the Study:

• To compare the efficacy of different grafting materials and techniques for alveolar cleft defects.
• Evaluate autogenous iliac crest bone, nano calcium hydroxyapatite with collagen, and tissue engineering with stem cells.

Main Methods:

• A comparative study involving 24 patients with alveolar cleft defects.
• Group A: Autogenous iliac crest bone graft.
• Group B: Nano calcium hydroxyapatite with collagen membrane.
• Group C: Tissue engineering using bone marrow stem cells extract and PRF membrane.

Main Results:

• Clinical and radiographic assessment of bone density at six months post-operation.
• Tissue engineering (Group C) demonstrated superior bone regeneration.
• Nano calcium hydroxyapatite (Group B) showed good results, while iliac crest (Group A) had resorption and donor site morbidity.

Conclusions:

• Bone substitutes, including nano calcium hydroxyapatite and stem cell-based therapies, offer reliable alternatives to autogenous bone grafts for ACG.
• Tissue engineering approaches show promising outcomes for alveolar cleft reconstruction.
