摘要: The purpose of this study was to develop and validate a new chin template system for two-piece narrowing genioplasty. Nine patients with wide deformities were enrolled. Surgeries planned the computer-aided surgical simulation (CASS) planning method. Surgical splints templates designed in computer fabricated using three-dimensional printing technique. included cutting guide repositioning These guides also avoid mental foramen area inferior alveolar nerve loops during osteotomy, protection. After surgery, outcome evaluation completed by first superimposing postoperative computed tomography model onto model, then measuring differences between actual outcomes. All surgeries successfully system. No damage seen study. With use templates, largest linear root mean square deviation (RMSD) segments 0.7 mm angular RMSD 4.5°. results showed that provides reliable method transfer osseous genioplasty planning.
