Abstract

Cinematic rendering (CR) is a novel 3D visualisation technique, which provides photorealistic image reconstructions with a high level of image details. Aim of this case series is to show the application of CR in Cone Beam Computed Tomography (CBCT) in dentomaxillofacial pathologies. Four exemplary CBCTs of clinical dentomaxillofacial cases were selected. 3D CR reconstructions were generated from the CBCT by using a vendor-provided standard CR software. Cases include 1) external tooth resorption, 2) ankylosed maxillary molar tooth, 3) giant cell-associated osteolytic lesion of the mandible, 4) unilateral cleft lip/palate with additional skeletofacial deformity. CBCTs of four patients showing dental and osseous pathologies were successfully reconstructed. Overall, a subjectively improved 3D understanding of the presented pathologies was observed. The CR images seem to present more plasticity, giving a better feeling for the spatial depth of the tissue. CR can be applied to CBCT images in dentomaxillofacial patients. The photorealistic appearance might improve the understanding of complex anatomy or pathology, could facilitate patient communication, and might be helpful for advanced medical education. We see potential in the use of CR for additional 3D visualization. The actual image diagnosis is done in the classic sectional planes. The significance of CR reconstruction for image diagnostics must be investigated in appropriate studies.
