Development of 3D CAD/FEM Analysis System for Natural Teeth and Jaw Bone Constructed from X-Ray CT Images
Open accessAbstract
A three-dimensional finite element model of the lower first premolar, with the three layers of enamel, dentin, and pulp, and the mandible, with the two layers of cortical and cancellous bones, was directly constructed from noninvasively acquired CT images. This model was used to develop a system to analyze the stresses on the teeth and supporting bone structure during occlusion based on the finite element method and to examine the possibility of mechanical simulation.

The attributes of linear, homogeneous, continuous, isotropic materials and a semicontrolled mesh with high-order tetrahedral elements are commonly used in biomodelling and numerical analysis on biological tissues and organs.
“All these attributes are commonly used when performing biomodelling and numerical analysis on biological tissues and organs [22, 37, 43–50].”
From Numerical Analysis of the ACL, with Sprains of Different Degrees after Trauma (2021) · cites this paper as [49]
Materials and Methods §§2.3–2.5 (pages unavailable) describe a linearly elastic bone model, specified mesh sizes, and tetrahedral elements. But §2.4 identifies the elements as four-node tetrahedra, not high-order elements; the paper also does not establish that the full set of stated material and mesh attributes is commonly used across biological tissues and organs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
