Objective: The aim: Identifying the relationship between the presence of oral habit and acquired maxillomandibular anomalies, influence of oral habits on the skeleton and muscular system formation in children.
Patients and methods: Materials and methods: We conducted clinical, radiological methods of examination of 60 patients aged 9-12 with acquired maxillomandibular anomalies, 15 persons aged 9-12 years without maxillomandibular anomalies and acquired deformities (norm group) and 15 persons aged 9-12 years with hereditary syndromes, which are combined with bone deformities in the maxillofacial area (comparison group).
Results: Results: Clinical examination showed that oral habits were manifested in 98.3% of patients. The results of clinical and radiological examination, analysis of cephalometric parameters and data on the thickness of the masticatory muscles on symmetrical areas of the face confirm the relationship between chronic oral habits and formation of acquired maxillomandibular anomalies; confirm the presence of acquired rather than congenital deformity of the facial skeleton, which is associated with changes in the thickness of the masticatory muscles on the part of the deformation та compensatory muscle hypertrophy on the opposite side.
Conclusion: Conclusions: The oral habit should be considered as one of the triggers in the development of acquired deformities of the maxillofacial area.
Keywords: acquired deformities of the maxillofacial area; cephalometric analysis; oral habits.
