Abstract
Objective: This study was performed with the purpose a report clinical cases involving condylar position and Nóbilo’s sliding plates. Background: Patients may present temporomandibular disorder (TMD), which is characterized by pain in masticatory muscles, temporomandibular joints and limited mandible movements. Treatment involving oral rehabilitation with the use of complete dentures with Nóbilo’s sliding plates has been an alternative for the treatment of TMD. Materials and Methods: Nine patients with a history of TMD signs and symptoms (RDC/TMD)—in particular, muscular and articular pain—received pain evaluations, mandibular movement analysis, transcranial radiography and an electromyographic analysis of the masseter and temporalis muscles before and after the use of complete dentures with Nóbilo’s sliding plates. Results: After treatment, the patients had reduced painful symptoms, an increase in mandibular movement and adequate electromyographic activity. The normalized EMG data were ta-bulated and analyzed statistically using SPSS version 17.0 for Windows (SPSS Inc., Chicago, IL, USA), and the values were compared by umpaired independent Student’s t-test. Conclusion: The use of Nóbilo’s sliding plates promoted improvements in electromyographic activity, muscular pain and man-dibular movement.
Highlights
Temporomandibular dysfunction (TMD) is characterized by facial and temporomandibular joint (TMJ) pain, mas-ticatory muscle tenderness, limited mandibular movement, joint sounds and an altered occlusal relationship [1,2].The etiology of temporomandibular disorder (TMD) is controversial because of the involvement of several features such as occlusion, stress, muscular hyperactivity and asymmetrical condyle position in the mandibular fossae [3,4].TMD signs and symptoms may be present in elderly patients and may occur in complete denture wearers [5]

Summary
The etiology of TMD is controversial because of the involvement of several features such as occlusion, stress, muscular hyperactivity and asymmetrical condyle position in the mandibular fossae [3,4]. TMD signs and symptoms may be present in elderly patients and may occur in complete denture wearers [5]. This is usually related to the patient’s general health, head posture, chewing efficiency [1], bite force [5], and complete denture conditions [6]. The use of complete dentures for years longer than recommended usually promotes a shift in the vertical and horizontal mandibular positions; as a result, the position of the condyles in the mandibular fossae may become altered
