The aim was to study the morphological state of the maxillofacial system in children with cerebral palsy. Materials and methods. The frequency and prevalence of dental anomalies was studied in 30 9—15 years old children with cerebral palsy. For the registration of maxillofacial anomalies, the Bjork assessment method was used. The severity of sagittal incisive disocclusion and the reverse sagittal incisal disocclusion was measured by the magnitude of the sagittal slit. Results. The study revealed no age-dependent correlation of lower canines and second premolars roots growth. The parameters of the cerebral part of the skull measured on the CT-bases lateral cephalograms were significantly less than normal rates except for the length of the posterior part of the skull. Conclusion. The morphological changes that determined the formation of sagittal and vertical incisive disocclusions were defined: the reduction of total anterior morphological face height (N—Me) and anterior upper morphological face height (N—SpP) and the increase in the anterior lower morphological face height (SpP—Me) which are characteristic features for patients with incisive sagittal and vertical diocclusion.
