This research examines how the anatomical components of the masticatory system (teeth, jaws, and related joints) work together and how these components are affected by aging and pathological changes. Specifically, we examine how the different anatomical components are correlated with each other across the entire masticatory system, in the context of changes that may occur during the lifetime of an individual, such as normal and pathological dental wear, and normal and abnormal (e.g., arthritis) changes in temporomandibular joint (TMJ) shape. We employ 3D models coupled with pathological data for a wide cross-section of 19 anthropoid primates, including humans. Though samples vary depending on specimen condition, ideally this dataset includes a 3D model of the cranium, mandible, and the teeth for each specimen (n>1000 individuals). Scan data provided are cleaned models (processed following standard protocols in Geomagic Studio); raw data (i.e., uncleaned original scans) will be provided upon request to Claire Terhune or Siobhan Cooke. Please be aware that some regions of the cranium (i.e., orbits, zygomatic arches, pterygoid fossa) may be more heavily reconstructed than others because of anatomical challenges related to scanning these areas.
