The technique of grafting two iliac bone blocks in restoring the alveolar process

We have developed the two iliac bone blocks autograft techniques in cleft palate reconstruction. A block of compact bone, with the size of the cleft, is placed on the nasal lining flap, then the iliac spongy bone is added until the cleft is nearly full. After that, a second bone block with both compact and spongy bone that is bigger than the cleft covering the entire gap and secured with screws. This technique combines the advantages of compact bone and spongy bone: the compact bone with the rigid mechanical property that helps to limit bone resorption and the implant easily achieve initial stability while the spongy bone with angiogenesis property and quick healing. Iliac crest bone can be obtained in large quantities that are recommended for large cleft or bilateral cleft.

Utilizing this technique show good results: 90.6% had type I bone that qualify for implant placement and the implant survival rate was 100% after 18 months of monitoring.
