“…The authors of these studies assert the importance of considering the irregular geometry of the PDL to obtain reliable results. Some FE studies use isotropic hyperelastic or elastic properties for the ligament or viscoelastic material models .

The periodontal ligament (PDL) is a soft biological tissue that connects the tooth with the trabecular bone of the mandible. It plays a key role in load transmission and is primarily responsible for bone resorption and most common periodontal diseases. Although several numerical studies have analysed the biomechanical response of the PDL, most did not consider its porous fibrous structure, and only a few analysed damage to the PDL. This study presents an innovative numerical formulation of a porous fibrous hyperelastic damage material model for the PDL. The model considers two separate softening phenomena: fibre alignment during loading and fibre rupture. The parameters for the material model characterization were fitted using experimental data from the literature. Furthermore, the experimental tests used for characterization were computationally modelled to verify the material parameters. A finite element model of a portion of a human mandible, obtained by microcomputerized tomography, was developed, and the proposed constitutive model was implemented for the PDL. Our results confirm that damage to the PDL may occur mainly because of overpressure of the interstitial fluid, while large forces must be applied to damage the PDL fibrous network. Moreover, this study clarifies some aspects of the relationship between PDL damage and the bone remodelling process.

“…The complex fibrous structure of the human PDL and the limitation of the experimental technology for the small-scale testing lead to an insufficient understanding of the deformation mechanisms and to difficulties in the accurate modelling of the constitutive behaviour [2][3][4]. Experimental studies based on animal tests [5][6] have shown that the PDL has non-linear viscoelastic behaviour. However, there is a large gap between the theoretical descriptions and the experimental observations of the constitutive behaviour of PDL under different loading conditions.…”

In this paper a dynamic thermomechanical analyzer was used to perform stress-relaxation tests on human periodontal ligament samples and a viscoelastic model is employed to correlate the test data. The results show that the stress-strain curves of the three samples can be predicted by the used constitutive model, which uses five parameters. The correction coefficients are larger than 0.99 for all tests, indicating that the five-parameter viscoelastic model is suitable for describing the viscoelastic behaviour of human periodontal ligament.

The clear aligner, commonly utilized in orthodontic treatment for malocclusion, necessitates the quantification of orthodontic forces, which is highly demanded by doctors for enhancing risk management and treatment efficiency. However, the current technology still faces obstacles in achieving conformal integration of pressure sensors onto clear aligners with large curvature for the quantification and real‐time monitoring of orthodontic forces. In this paper, a conformal iontronic sensing clear aligner (CSA) is proposed based on flexible iontronic sensing mechanism, which conformally integrates the sensor with the aligner to quantify orthodontic forces throughout the treatment process while preserving the aligner's original function. Specifically, the ionic coating is seamlessly integrated onto the diaphragm by applying a layer of ionic paint before molding the clear aligner, while the sensing electrode array, designed using a kirigami‐based structure, is seamlessly adhered to the ionic coating. By integrating the CSA into a dental model, its exceptional sensitivity and precise pressure mapping capabilities have been demonstrated. This enables the identification of various tooth movement patterns, discernment of orthodontic force magnitude, and continuous monitoring of forces throughout the orthodontic treatment. Consequently, this research is expected to significantly advance risk management, outcome prediction, and treatment efficiency in orthodontic treatments.
