Abstract

Objective: Evaluation of certain indices on CBCT imaging in adult patients with temporomandibular joint disorders (TMD) after 6 months of treatment with stabilization splints (SS) in Hanoi City from 2022 to 2024. Subject and methods: A descriptive cross-sectional study on CBCT imaging in adults with temporomandibular joint disorders (TMD) treated with stabilization splints (SS), with imaging performed and analyzed at two time points: before treatment and 6 months after treatment. Results: The triangular condylar head morphology accounted for the majority (45,1%), while convex and round morphologies had the lowest proportion (9,7%). The dimensions of the posterior condylar space (PS) and superior condylar space (SS) were larger before treatment compared to 6 months after treatment. The proportion of patients without damage increased from 12,92% to 19,37% after treatment, while the prevalence of mild wear with cartilage thinning decreased from 41,93% to 35,48%. Conclusions: The distribution of condylar head morphology remained unchanged before and after 6 months of treatment. After 6 months of treatment, the condylar position shifted anteriorly and moved closer to the central position compared to before treatment. The majority of condylar head damage before treatment was in the form of wear with remaining cartilage.
