Objective: To investigate the clinical use of cone beam computed tomography in the diagnosis of patients with odontogenic jaw keratocyst and to guide computer-aided surgical treatment planning.

Methods: Imaging, image processing, and visualization technologies were used to produce clear diagnosis, provide proper treatment, and formulate favourable prognosis. Cone beam computed tomography was used to collect medical information including site, extent, shape, and other characteristic features of a patient with large odontogenic jaw keratocyst.

Results: The imaging technique produced excellent results in imaging, image processing and threedimensional (3D) visualization.

Conclusion: The 3D digital reconstruction model of the odontogenic jaw keratocyst was shown intuitively.
