Computational models and their applications in biomechanical analysis of mandibular reconstruction surgery

“…By analyzing the principal stress and strain values, it is possible to determine the magnitude and direction of the stresses and strains acting on the attached components and surrounding bone tissue [52,71,76]. Furthermore, among all reviewed papers, there are five studies that measured strain energy density (SED) in FEA of mandibular reconstruction [18,73,78,79,84], which is defined as the energy stored in a material due to deformation [100]. In literature, the strain energy density (SED) per unit apparent density has been widely accepted as an appropriate mechanical stimulus for jawbone remodeling [101,102].…”

“…Alongside examining various bone flap anatomies, five studies assessed bone remodelling following mandibular reconstruction, which allows researchers to predict the likelihood of bone union after the surgery [18,73,78,79,84]. Underloading resorption, equilibrium, apposition, and overloading resorption are the four phases of bone remodeling, according to Zheng et al [73], and strain energy density (SED) per unit apparent density has gained widespread acceptance as an appropriate mechanical stimulus for jawbone remodeling [101,102].…”

“…The structural aspects of titanium have been modified in some studies to explore the computational modeling of varying macro and microstructures of the titanium. In more recent years (2020-2022), researchers have introduced novel materials including polycaprolactone (PCL), polyetherketoneketone (PEKK), polyetheretherketone (PEEK), bioceramic tissue scaffolds, and aluminium oxide (AL2O3) [61,62,78,84].…”
