This study aimed to correct complicated alveolar defects with autogenous iliac bone blocks, thereby facilitating subsequent dental implant-supported restorations. Using a retrospective study design, 27 consecutive patients (age, 19- 63 years) who underwent iliac “J-bone block” procedures from 2006 through 2010 were enrolled. All the reconstruction materials were harvested from the superior and medial aspects of the anterior iliac crest. Each iliac bone block was tailored to passively fit the contour of the alveolar defect and secured in position by titanium mini-screws to achieve significant bone volume expansion in both the transverse and vertical dimensions. Pre and post-operative computed tomography imaging studies with a radiographic guide in position were conducted to evaluate the changes in shape and volume of the recipient sites. All iliac bone grafts healed uneventfully with minimal volume shrinkage and unremarkable donor site morbidity. A total of 73 dental implants in 21 patients appeared clinically healthy. Iliac cortico-cancellous bone blocks were easily manipulated by hand instruments and transformed into a J-bone block, which lead to high-quality bone augmentation and allowed ideal implant positioning with proper axial alignment. We suggest that iliac J-bone block be used in the near future to improve the success rate of complicated implant restorations.
