Description
Summary:The mechanical behavior of each type of pacifier on rigid structures and their various impacts on orofacial growth have yet to be discovered. The study aimed to evaluate the stress distribution over a child's palate by three types of pacifiers using finite element analysis and clinical and laboratory data. Modulus of elasticity was obtained from 30 specimens comprising 10 of each conventional (A), orthodontic (B), and breast‐shaped (C) pacifiers. Tongue strength was assessed in eight 3‐year‐old children (kPa). A hemi‐maxilla model was obtained from 2‐ to 3‐year‐old skull tomography, and the images of pacifiers A, B, and C were captured using 3D scanning. The Hypermesh® program generated a mesh of 6‐node tetrahedral elements for applying forces in the X, Y, and Z directions to enable a nonlinear analysis. Pacifier B exhibited the highest values for distributed stress on the palate, followed by pacifier A. Pacifier B stimulated the maxilla forward and sideways. In contrast, pacifier A promoted a forward and upward load, favoring a more atresic palate. Pacifiers A and B tended to rotate in the sagittal plane, generating tensions in the anterior incisors and favoring the open bite. Pacifier C exhibited lateral expansion by stress induction over the mid‐palatal suture with less influence on incisor inclination. Pacifiers showed different detrimental stress distributions on the palate. This information can be helpful for improving recommendations given to parents.
