Introduction. Facial asymmetries associated with lateral displacement of the jaw arise due to various reasons, namely, the presence of functional lateral displacement of the lower jaw, skeletal asymmetry of the maxillofacial region, and a combination of the above factors.
Purpose. Identification of the etiological factor makes it possible to assess the possibility of correcting the position of the lower jaw and improving the relationship of the intra-articular structures of the temporomandibular joint.
Materials and methods. Functional lateral displacement of the lower jaw is characterized by an asymmetric tone of the masticatory muscles, a change in the position of the chin, and dysfunction of the temporomandibular joint on the side of the displacement of the lower jaw. The article discusses a clinical case of a patient with pathology of the temporomandibular joint associated with functional displacement of the mandible. Comparison of the data of cone-beam computed tomography of the lower jaw at the site of attachment of the masticatory muscle before and after the elimination of the asymmetry of the maxillofacial region was carried out.
Conclusion. An asymmetric change in the displacement of the condyles was obtained according to the data of electronic axiography, an improvement in the ratio of intra-articular structures, the presence of a change when comparing STL models of the lower jaw.
