Cleft Alveolus Reconstruction Using a Three-Dimensional Printed Bioresorbable Scaffold With Human Bone Marrow Cells

In this study, a clinical case using patient-specific 3D-printed bioresorbable scaffold with bone marrow stromal cells collected from iliac crest in the operating room has been introduced. At 6-month after transplantation, the bone volume of the newly regenerated bone was approximately 45% of the total defect volume. Bone mineral density of the newly regenerated bone was about 75% compared to the surrounding bone. The Hounsfield unit value was higher than that of cancellous maxillary alveolar bone and lower than that of the cortical maxillary alveolar bone. Bone-marrow-derived mesenchymal stem cells-seeded 3D-printed patient-specific polycaprolactone scaffolds offer a promising alternative for alveolar cleft reconstruction and other bony defects.
