Computer-Assisted Orthognathic Surgery for Patients with Cleft Lip/Palate: From Traditional Planning to Three-Dimensional Surgical Simulation
Fig 2
In the first step, the patient’s initial preoperative Cone-Beam Computer Tomography (CBCT) defines Position0. After segmentation, the conventional orthodontic 2D plan is transferred into the 3D simulation and recorded as Position1. The transferred plan is then adjusted for roll, midline, pitch, yaw, and genioplasty positions by the surgical team, and the resulting 3D simulation is noted as Position2. The changes in each parameter from Position1 to Position2 are recorded and evaluated.
