Orthodontic treatment strategy in patients with dental arch asymmetry in the diagonal direction taking into account craniofacial morphology

Abstract

Based on the results of morphological studies of the craniofacial complex, biometrics of plaster models of the jaws of 76 young people (18-25 years old) with asymmetry of dental arches, an algorithm was developed for modeling the predicted sizes of dental arches with their asymmetry in the diagonal direction. The methodological approach is based on the use of individual cephalometric indicators (diagonal and transverse face size), morphometric parameters of dental arches (incisor-molar diagonal, transverse intermolar arch size, dental arch depth) and stable correction factors for assessing the conformity (inconsistency) of real and predicted biometric data. Further stages of modeling the predicted sizes of dental arches with their asymmetry in the diagonal direction include the construction of incisor-molar and incisor-canine triangles, taking into account the anthropometric parameters of the maxillofacial region. The use of a diagnostically significant method in the clinic of orthodontics makes it possible to establish the topography of key teeth (canines, second molars) in the dental arch, taking into account the individual characteristics of the patient’s craniofacial complex. The implementation of the obtained results in clinical dentistry in patients with asymmetry of dental arches in the diagonal direction is advisable to substantiate the methods (extraction, without extraction) of complex treatment in order to achieve a functional balance of occlusal relationships, as well as optimal balance of morphological, functional and aesthetic characteristics.
