Root resorption may progress to replacement resorption, with ankylosis, a lack of mobility and a clinical finding of a metallic tone on percussion and characteristic infra-occlusion. A, CBCT cross-sectional reformation of the maxillary left central incisor showing replacement resorption. B, CBCT sagittal slice through ankylosed region C, CBCT axial reformation. D, Standard VRT image optimized using manufacturer’s software. E, Cinematic rendering technology (CRT) of an identical CBCT dataset using open-source software. CRT uses a more complex algorithm than volume rendering technology (VRT), providing a photorealistic reformation of imaging data which may aid in visualizing anatomic and pathologic structures and improve patient education. F, AI-generated .STL image with semi-transparent maxilla showing replacement resorption and its extension into the surrounding alveolus. G, AI-generated .STL model of maxillary left central incisor demonstrating ankylosis along the mesial of the middle third of the root.
