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.
电影渲染（CR）是一种新型的3D可视化技术，它能提供具有高度图像细节的逼真图像重建。本病例系列的目的是展示CR在牙颌面病理学锥形束计算机断层扫描（CBCT）中的应用。选择了四个临床牙颌面病例的典型CBCT。使用供应商提供的标准CR软件从CBCT生成3D CR重建图像。病例包括：1）外源性牙齿吸收；2）上颌磨牙粘连；3）下颌骨巨细胞相关溶骨性病变；4）伴有额外颌面骨畸形的单侧唇腭裂。成功重建了四名患有牙齿和骨质病变患者的CBCT。总体而言，观察到对所呈现病变的3D理解在主观上有所改善。CR图像似乎呈现出更多的可塑性，能让人更好地感受组织的空间深度。CR可应用于牙颌面患者的CBCT图像。逼真的外观可能会改善对复杂解剖结构或病变的理解，有助于与患者沟通，并且可能对高级医学教育有帮助。我们认为使用CR进行额外的3D可视化具有潜力。实际的图像诊断是在经典的断面进行的。CR重建对图像诊断的意义必须在适当的研究中进行调查。
