Inclusion criteria
Inclusion criteria: Inclusion Criteria: Each selected radiographic sample must be from the same patient, and the patient must have both a lateral cephalogram and a panoramic radiograph. The radiographs must be taken before the initiation of orthodontic treatment, as the skeletal pattern may change during or after treatment, which could affect the experimental results. Furthermore, all radiographs must be clear, complete, suitable for accurate landmark identification, and must not be screenshots.
Exclusion criteria
Exclusion criteria: Exclusion Criteria: Patients were excluded if the time interval between their panoramic radiograph and lateral cephalogram exceeded three months. Additional exclusion criteria included a history of prior orthodontic treatment, orthognathic surgery, or any other treatment that could alter the craniofacial skeletal structures. Furthermore, patients with congenital craniofacial syndromes (e.g., cleft lip/palate), jaw fractures, jaw tumors, severe bony temporomandibular joint pathologies, or other systemic skeletal diseases were excluded. Radiographs were also excluded if they exhibited excessive distortion, artifacts, underexposure, overexposure, or if any key anatomical landmarks (such as the Orbitale, Porion, or lower border of the mandible) were blurred or unidentifiable for any reason. Finally, images where the patient's positioning was severely incorrect, such as significant head tilt in the sagittal or coronal plane that could not be reliably corrected using software functions, were also excluded.
