[Clinical efficiency of occlusive splints in the treatment of patients with temporomandibular joint dysfunction complicated by bruxism].

Objective: Improving the effectiveness of treatment of patients with temporomandibular joint (TMJ) dysfunction complicated by bruxism.

Material and methods: 70 patients with signs of parafunction of the masticatory muscles were selected for the clinical study. The patients were divided into 2 groups of 35 people. Splints were made for patients from the groups using 2 different 3D printing methods. The treatment was monitored using clinical and instrumental studies, electromyography of the muscles themselves and computed tomography of the TMJ after 3, 6 and 12 months.

Results: The severity of hypertonicity of the masticatory muscles decreased by the end of 3 months of treatment with the help of repositioning occlusal splints. After 6 months of treatment, the mean BEA decreased in both study groups, but to a lesser extent than in the first 3 months. After wearing a splint after 12 months, the decrease in muscle tone was insignificant.

Conclusion: The clinical use of positioning splints plays a crucial role in the stabilization of occlusion and is a mandatory stage of complex treatment of patients with pathology of the occlusal-musculoskeletal complex.
