The aim of this study is to evaluating the effectiveness of use of Michigan splint in the management of Temporomandibular joint disorders (TMD) in comparison to superior repositioning splint (SRS) as a control group in a one-year follow-up..
Material and methods: Sample was initially constituted by 40 patients, randomly divided into two groups: I- Michigan splints, II- Superior repositioning splints. The whole sample was evaluated by means of TMJ and muscle palpation, mandibular range of motion (ROM), analysis of occlusal contacts, joint sounds inspection and Visual Analogue Scale (VAS) for one year.
Results: A significant (after 15 days) improvement in pain report (VAS) and palpation index was found for group II (p²0.01). The occurrence of occlusal alterations as posterior open bite or gross interferences after the splint therapy and increased muscle tenderness were not problems in this study. Similar results in joint noises reduction were observed for the entire sample.
Conclusion: It was concluded that use of repositioning splints is a beneficial tool in the management of intra-articular pain and dysfunction, with no risks of irreversible occlusal changes.
