This repository represents an open-access dataset including reconstructed geometries acquired from the cone-beam computed tomography (CBCT) of three patients' jaws for research purposes only. Each patient’s data includes surface meshes of the mandible, full mandibular dentition, and associated periodontal ligaments (PDLs) stored in the Stereolithography (STL) file format. Further details on the structure of the dataset can be found in the zip file.
