“…Natali et al (2007Natali et al ( , 2008 addressed the biomechanical behaviour of the PDL with the development of a visco-hyperelastic-damage structured model. The justification for such a model was that soft tissues, including the PDL, show a strongly nonlinear and time-dependent mechanical response and can undergo large strains under physiological loads.…”

“…In addition, a hyperelastic model was developed to simulate the behavior of the PDL. Many studies have investigated the biomechanical behavior of the PDL by using specimens from various animals, such as rats, rabbits, and pigs (Dorow et al, 2002;Kawarizadeh et al, 2003;Komatsu and Chiba, 2001;Komatsu et al, 2004;Natali et al, 2007). Animal models such as these have become viable alternatives when studying the biomechanics of the PDL because it is difficult to obtain complete human tooth samples.…”

“…Pini et al reported the mechanical response of the PDL, which was obtained from different portions of bovine incisors and molars when they were subjected to uniaxial tension and compression (Pini et al, 2004). In other research, a laser-optical system was designed to verify the behavior of porcine teeth and the existence of hysteresis under different strain rates was reported (Dorow et al, 2002(Dorow et al, , 2003Natali et al, 2007). Although the sliced samples were taken from part of a tooth, the results of these studies reflect the typically non-linear behavior of the partial PDL, but may not be representative for the entire PDL.…”

In recent years, orthodontic treatments have become increasingly popular. In these treatments, orthodontic forces, which cause the absorption and deposition of alveolar bone, are applied through brackets and teeth in order to move the teeth to the expected position. The periodontal ligament (PDL) has a determinative role in dental biomechanics; however, the difficulty of predicting PDL behavior has limited the advancement of dental biomechanics. Therefore, this study intends to measure the biomechanical behavior of the PDL and then develop an analytical model to predict the holistic force-displacement relationship of the tooth. In this study, a porcine premolar, including the tooth, periodontal ligament, and alveolar bone, was harvested for experimental purposes. A custom-made apparatus was designed to measure the force-displacement relationship of the PDL. Three analytical models, including linear, exponential, and power functions, were adapted to fit the experimental results. In addition, three-dimensional finite element models were constructed from micro-CT sectional images, and the hyperelastic behavior (Mooney-Rilvin equation) of the PDL was simulated. The results showed that the PDL exhibited nonlinear biomechanical behavior. The power function was found to be a good fit for the force-displacement relationship of the PDL. Furthermore, it was found that the hyperelastic model could predict the biomechanical behavior of the PDL for tension less and equal to 20 N.

“…There are articles in literature proving that the material properties of the PDL are linear, elastic and isotropic [11,13,16,26,27]. On the other hand the most current publications [12,15,28] indicate that PDL is not a homogenous material and its properties are non-linear. In terms of this recent concept, the methodology of the presented work, that is defining PDL as isotropic or elastic but with strong non-linear stress and strain characteristics, is fully justified.…”

Abstract. This study aimed at the simulation of bone tissue remodeling within a bone defect with the utilization of the finite element method (FEM), enabling -via elaborated application -objective evaluation of orthodontic forces which positively influence periodontium in vivo. The initial position of each bracket on the passive archwire was registered, and then a geometrical and discretemodel of the appliance was created automatically. Assessment of the dental scans obtained using cone beam computed tomography (CBCT) allowed evaluation of the range of bracket displacement: from the initial position to the final one achieved on the active archwire. Those displacements established terminal conditions in the finite element analysis, enabling calculation of orthodontic force levels. An individual design of a tooth with periodontal ligaments and the periodontal defect subsequently loaded with the determined forces allowed simulation of bone remodeling according to Carters adaptation process. Mainly, the bone apposition processes took place in the central part of the periodontal defect, in proximity of the alveolar ridge. However, FEM application in the analysis of bone tissue regeneration within bone defects enables precise evaluation of the achieved changes, therefore allows determination of orthodontic forces positively influencing periodontium in vivo.
