Currently, there is an urgent need to address the diagnosis and identification of the causes of temporomandibular joint disorders. The current realities in dentistry significantly contribute to this problem: the use of high-strength and rigid materials, the abundance of total restorations and orthodontic treatment, and the lack of comprehensive diagnosis of the maxillofacial region to identify hidden, compensated temporomandibular joint pathology before dental intervention. All of this leads to the emergence of patients with pronounced, developed symptoms. The goal is to examine the relationship between various occlusal disorders, specifically between lateral mandibular displacement and internal temporomandibular joint disorders (or disc dislocations, intra-articular elements).Methods and materials. Based on literature data, an assessment of the prevalence of disc dislocation was conducted, and various etiological factors of internal temporomandibular joint disorders were considered, particularly certain types of pathological occlusion that can significantly impact the disturbance of the relationship between intra-articular elements. As an example, two clinical cases with temporomandibular joint disorders with similar symptoms and the presence of transverse bite pathology due to incorrect jaw growth and acquired pathology during dental interventions are presented. Conclusion. It has been found that transverse bite pathology typically provokes temporomandibular joint dysfunction and internal joint disorders. Further research will focus on identifying occlusal factors that are highly likely to trigger the development of temporomandibular joint disorders, studying their mechanism of influence, and exploring methods of detection.
