Corrigendum to Balancing the spatial demands of the developing dentition with the mechanical demands of the catarrhine mandibular symphysis [J Anat, 218, (2011), 96-111]

摘要

Cobb and Panagiotopoulou (2011) assesses the effect of the presence of developing incisor tooth crypts on strain in the developing mandibular symphysis using finite element analysis. The paper also includes a secondary study investigating the sensitivity of the same finite element mandible model to the inclusion of the periodontal ligament (PDL). This was assessed by comparing the strains between a model with (PDL Model) and without the PDL (No PDL Model). The results presented in the paper for the No PDL model are incorrect (Table 1, Table 2, Figs 5 and 6). In order to model the mandible without PDL in the finite elements analysis, the PDL region should have been assigned the material properties of the surrounding cortical bone, with a Young's modulus of elasticity of 17GPa (17000MPa), but in error it was modelled with a value of 0.017GPa (17MPa).
