The finite element modeling of the stress-strain state of a human skull during maxillary expansion using different designs of the orthodontic device HYRAX is carried out.The finite-element models of the craniofacial complex and Wooden Toys supporting teeth are obtained on the basis of the tomographic data.Orthodontic appliance designs differ in the locations of the screw relative to the palate.The design with the location of the device rods and the screw in the same horizontal plane as well as the design with the location of the screw on 8 mm closer to the palate relative to the horizontal position are considered.Activation of the screw is carried out on Theraphy Device Pads a half turn.
The displacements vector fields of a intact skull, a skull with a palate cleft, and the supporting teeth are obtained.Regions of the largest displacements of the skull bone structures are defined for different designs.Influence of the orthodontic appliance design on displacements of the supporting teeth is analyzed.The results can be used for the design of devices HYRAX for the treatment of cross-bite with taking into account the patient individual features.
