Periodontal Ligament Strains from Orthodontic Attachment Simulations

Aggregating finite-element simulation results of maximum strains in the periodontal ligament (PDL) during clear aligner orthodontic treatment. It compares five attachment shapes and dual configurations across four tooth movements, with PDL strain values up to 0.390 mm/mm.

Use Cases

• Compare PDL strain values across five attachment shapes (square, rectangle, trapezoid, ellipse, semicircle) to evaluate biomechanical impact.
• Analyze the effect of single versus dual attachment configurations on localized bone stress and crown displacement.
• Correlate attachment geometry with movement types (mesialization, intrusion, extrusion, rotation) to assess rotational control efficiency.
• Model the relationship between PDL strain and bone stress, particularly at the root apex and alveolar crest, for risk assessment.

Strengths

• Data is derived from a subject-specific 3D maxillary model developed from CBCT imaging, incorporating detailed anatomical structures.
• Simulations cover five distinct attachment shapes and four clinically relevant orthodontic movements, providing comparative analysis.
• Results include specific quantitative metrics, such as a maximum PDL strain of 0.390 mm/mm and localized bone stress of 7.11 MPa.

Limitations

• The dataset is very small at 5.5 KB, indicating limited scope and likely a small number of simulation runs or summary results.
• As simulation data from a single subject-specific model, findings may not generalize across different patient anatomies.
• The underlying raw data, columns, and sample data are unavailable, limiting detailed reproducibility and secondary analysis.
