The aim of this study is to evaluate the efficacy of the use of superior repositioning splints in the management of Temporomandibular Joint Anterior Disc Displacement with Reduction cases in a one-year follow-up. The study included 60 patients who were selected from the TMJ outpatient clinic of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Assiut University and all were treated with a superior repositioning splint. The entire sample was examined using unassisted mouth opening and the Visual Analogue Scale (VAS). The records were taken at three time points, pre-treatment (before using the splint), after 6 months and after 12 months of using the splint. There was a considerable significant improvement in the visual analogue scale report and the range of unassisted mouth opening. It was concluded that the use of superior repositioning splints is an effective strategy in the treatment of Temporomandibular Joint Anterior Disc Displacement with Reduction.
