The Cone Beam computerized tomography system (CBCT) is used worldwide by medical and dental professionals. The purpose of this system is to correct distortions in the orientation of the tomographic images obtained so that the diagnosis and treatment plan is determined with greater precision.

Objective: Integrate 3D imaging to the protocol study and treatment planning for orthognatic patients.

Materials and method: 3D images taken with a Kodak 9500D Cone Beam with the patient in natural head position. Image size calibration spheres were used but no facial support was needed. Radio-opaque spheres transferred the true horizontal that was determined clinically for each patient just before the image was taken.

Conclusion: It is possible to obtain 3D images that are correctly oriented, calibrated and that accurately reproduce a spacial reference such as the true horizontal, as well as not altering the soft tissues, with is necessary in order to integrate these images with the clinical photographs of the patient.

Conflict of interest: None declared.
