Allogenic versus autogenic iliac bone grafting in atrophic anterior mandible

Bone grafting plays a pivotal role in reconstruction of atrophic ridge in dental implants.This study made a comparison of the efficacy of allogenic and autogenic (iliac) bone grafting using  the same technique (interpositional bone grafting) in increasing the mandibular anterior height. Ten partially edentulous patients who required vertical bone augmentation
of the anterior mandible (having a residual ridge with 10 to 12 mm) were randomly  allocated to autograft (iliac) and allograft groups. The heights of ridges were measured at three points (Right, Left, and Middle) using preoperative panoramic radiography three and six months  following grafting. The heights of ridges increased in all patients, but there was no significant difference between the two groups. This study indicated autograft and allograft had similar effects on vertical augmentation.
