Finite Element Analysis of a New Custom Made Orthotropic Post Material for Dental Applications
Bibliographic record
Abstract
Effects of cement properties on stress distributions at the dentin-cement-post interfaces have been studied using 3D explicit finite element simulations. The mastication and horizontal loadings are simulated with titanium and glass fiber posts. Different type of cements (moduli 2,8,18 and 22 GPa) is considered to study the interface stresses. The interface stresses are evaluated at dentin-cement-post interfaces and along the surface of the post and cement. The element deletion technique from finite element analysis has been used to predict the cement failure. The simulation results suggest that the cement with similar modulus as dentin is preferable to avoid the stress concentration at the dentin-cement interface. The types of cement do not affect the failure initiation location on the cement. Under the simulated conditions, the failure initiation is located at 1.7 to 2.2 mm from the post apex.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
