Abstract:

Aim: The aim of this study was to evaluate the effect of stabilization splint therapy on TMD and to determine if there is a relationship between the condylar axis position as determined by the occlusion and signs and symptoms of TMD, using the condylar position indicator (CPI III). Subjects and Method: A sample consisted of 35 untreated subjects with mild, moderate or severe symptoms of TMD. The centric relation bite registration technique developed by Roth was used. All subjects underwent stabilization splint therapy during average period of 6 months, for the stabilization of temporomandibular condyles in centric relation (CR). The comparison was based on written patient histories, clinical exams, and CPI measurements. The condylar displacements for 35 subjects were measured in vertical, sagittal and transversal components from mounted models using CPI III system. Obtained data was evaluated using Wilcoxon signed-rank test. Results: When the pretreatment and posttreatment examination scores were compared, an 80% reduction in symptoms was found after treatment. A high correlation (p<.001) between signs and symptoms of TMD and CPI values was documented. Conclusions: After stabilization splint therapy, a stable centric condylar position was obtained, as a predisposition for correct orthodontic treatment planning. In patients with signs and symptoms of TMD, and significant discrepancy between the centric relation and maximum intercuspation, stabilization splint therapy is highly recommended prior to treatment with fixed orthodontic appliances.
