Biomechanical Evaluation of Neuro-occlusal Rehabilitation for Occlusal Imbalance Correction in Children with Facial Asymmetry

Abstract

Contemporary eating habits may cause malformations in children jaw, that are difficult to evaluate and treat clinically. In this work, a computational methodology for the diagnosis and the treatment of this pathology is proposed. It combines porous-fibrous material models, medical devices and computational models of patients with facial asymmetries from the perspective of neuro-occlusal rehabilitation.

In silico approach towards neuro‐occlusal rehabilitation for the early correction of asymmetrical development in a unilateral crossbite patient

“…The parameters (C 1 , D, k 1 , k 2 and J) of Equations 2.1, 2.2 and 2.3 (shown Table 3) that describe the behaviour of articular discs and cartilage are the result of a previous work. 91 They were obtained by fitting the stress-stretch relation 87 of Equation 1 to literature tensile tests of human disc specimens 2 and porcine cartilage, 3 through a nonlinear least-squares fitting procedure using MATLAB commercial software (MATLAB 6.0 R12, The MathWorks Inc., Natick, MA, 2000).…”

“…More details of the fitting procedure can be found in our previous publication. 91 According to their collagen network, 86,94 each tissue was divided into five regions (anterior, central, posterior, medial and lateral) with different mechanical properties (shown Table 3) and fibres' orientations (shown Figure 3D-F). The fibres orientations in each element of TMJ disc and cartilages sections, represented by a 0 vectors, were defined based on experimental data from the literature.…”
