OpenMandible: An open-source framework for highly realistic numerical modelling of lower mandible physiology. Dental Materials (2021). https://doi.org/10.1016/j.dental.2021.01.009 Repository: https://github.com/ArsoVukicevic/OpenMandible Pinned source commit: e1f8cef196adb29149a2193ffb0cb05dab631420 Source folder: 00 OpenMandible Base model/materials/stl 42 original STL files provide enamel, dentin and pulp for 14 mandibular positions (left/right central incisor through second molar). Source third molars are absent. Current app positions supplied by this source: #20, #22–27 and #29. Source positions #19, #21, #28 and #30 were reviewed but superseded by separate prototypes (#19/#30 Kato; #21/#28 Kato until 2026-10-12, now ACTA-DIRECT v2). Source #18 and #31 (Tooth_L7/R7) were shown until 2026-10-12 and were then replaced by ACTA-DIRECT v2 tooth 0056; their converted files remain in the local model archive but are no longer packaged in the app. After cingulum/mesial-distal review on 2026-10-14, original source-labelled L1/L2 geometry is displayed at #25/#26, with its explicit X mirrors at #24/#23. The authors' Left labels are retained in provenance; the reviewed right-side display orientation differs from those labels. Original R1/R2 source and converted files remain preserved locally; the mirrored derivatives use separate filenames. The paper reports nominal 10-micrometer micro-CT acquisition and dentist tissue annotations. The supplied STL surfaces were processed by the authors using Mimics and Geomagic repair, cutting, merging and smoothing for finite-element analysis; they are coarse exports and do not retain 10-micrometer surface detail. The original source DICOM was not provided here. All four source mandibular incisors are effectively one reused shape after rigid alignment: the same enamel crown and nearly the same dentin and pulp, with right-side copies that are not mirror images. The displayed left incisors mirror the source geometry placed on the right across all registered tissues, with reversed winding and reflected normals. The cingula face distally in the reviewed display assignments; source filenames retain historical numbers and the manifest determines the current position. This corrects display handedness; the set still does not establish independently reconstructed central versus lateral, or side-specific specimen morphology. Our conversion preserves every source triangle and source scale, welds coincident STL vertices for conventional vertex normals, and applies one shared proper rigid rotation/translation to enamel, dentin and pulp for each tooth. The source jaw layout supplies the display frame. No tissue generation, triangle decimation, geometry smoothing, hole repair or synthetic canals were applied. The two deliberate incisor mirrors preserve the original source scale and every triangle; native optical attributes are baked separately for each reflected derivative. Display colors, enamel optics and typodont arrangement are illustrative. Reuse status: permission-pending-prototype-only. No asset license was found at repository root or in the base-model folder. GPLv3 files elsewhere in the repository cover framework/use-case folders; their presence does not establish the license of these base-model STL assets.
