FEATURES OF ORTHOPEDIC TREATMENT OF PATIENTS WITH DEEP INCISOR MALOCCLUSION WITHOUT REDUCING THE HEIGHT OF THE GNATHIC PART OF THE FACE: A CLINICAL CASE

Relevance. Deep incisor disocclusion is characterized by excessive overlap of the upper anterior teeth with the lower anterior teeth and the absence of incisal-tubercular contact between the anterior teeth. The pathology occurs in two main conditions: without a decrease in the height of the gnathic part of the face and with a decrease. There are different opinions on the methods, materials and timing of orthodontic and orthopedic treatment of various forms of deep incisor disocclusion. Deep incisor disocclusion leads to a violation of aesthetics, causes serious functional and morphological changes in the masticatory apparatus, which are most clearly manifested in adulthood. In recent years, much attention has been paid to the comprehensive treatment of adult patients with deep incisor disocclusion due to its significant prevalence and, consequently, a high need for special treatment. Results. The article presents a clinical case of deep incisor disocclusion without a decrease in the height of the gnathic part of the face. The patient underwent morphometric and functional examination. The results of the analysis of tomograms of the temporomandibular joint showed that the position of the head of the lower jaw in the temporomandibular fossa corresponded to its distal position, but we did not observe any pronounced morphological changes in the elements of the joint. At the same time, the patient experienced discomfort when chewing, lateral movements of the lower jaw were blocked, which required disengaging the bite height with prosthetic structures: first, a bite disengaging plate with a bite pad in the area of the anterior teeth, then after 3 months, the included defects of the dental arches in the lateral sections of the upper and lower jaws were replaced with metal-ceramic bridge prostheses. Conclusion. The prosthetic treatment was highly effective and improved the functional indicators and facial features of the patient, changed the ratio of the elements of the temporomandibular joint, and led to the normalization of the tone of the masticatory muscles.
