Three-dimensional simulation of the nasoalveolar cleft defect.


This study describes the planning process for a three-dimensional (3D) model of a nasoalveolar bone graft in patients with unilateral cleft lip and palate. A 3D reconstruction of the alveolar cleft based on cone-beam computed tomography was performed in 10 patients. Graft models were planned using a 3D planning software (iPlan ENT 3.0, Brainlab, Feldkirchen, Germany) and printed using a 3D printer (Objet30 Pro, Objet Ltd., Rehovot, Israel). A reproducible, step-by-step planning method was established, which is manual rather than automatic. Still, the 3D visualization and a life-size graft template could be useful during secondary alveolar osteoplasty.
