Introduction: Cone beam computed tomography (CBCT) is a new diagnostic and treatment planning tool in orthodontics. The purpose of this thesis is to determine precise landmarks that can be used for cephalometric superimposition of the maxilla and the mandible. A maxillary plane will then be determined for superimposition of CBCT and tested in a clinical context.
Methods: The CBCTs of ten skulls were used to test the precision and accuracy of the landmarks. Next, CBCTs and plaster models of thirty patients were used to test and validate the proposed 3D superimposition technique of the maxilla.
Results: Nasion, incisive foramen, bilateral infraorbital, mental foramina and anterior nasal spine were all precise and accurate landmarks to use in the formation of a maxillary superimposition plane. Comparison of the proposed superimposition technique with a gold standard demonstrated excellent agreement.
Conclusion: The proposed maxillary superimposition plane can be used as a regional superimposition technique.
