“…Significant JFLS-20 scores reduction have been reported in patients with arthrogenic TMD using resilient OS but without significant differences versus other treatments in the follow-up [38]. While other reports nonsignificant difference in JFLS-20 scores between improvement and non-improvement patients treated with resilient OS in patients with subacute and chronic TMD [39]. Other reports found non-significant JFLS-20 scores reduction using stabilization OS splints for chronic TMD [40] and masticatory myofascial pain [41], which suggest that OS therapy that can reduce pain and improve range of motion, may not be better that other treatments to improve mastication and verbal and emotional expression in patients with myogenic TMD.…”

Objective: Compare the clinical effectiveness of custom thermoformed occlusal splints (OS) alongside behavioral and self-care therapy (BST) in the management of myalgia of the masticatory muscles. Material and methods: A controlled clinical trial was conducted with a total of 46 subjects with a diagnosis of myalgia according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). All subjects were treated with BST at the beginning of the study and were then randomized into four groups: behavioral and self-care control group; Thermoformed Tough-elastic splint group; Thermoformed Soft-elastic splint group, and non-occlusive splint group. Follow-ups were carried out at 2, 6, and 10 weeks, where it was evaluated: pain in the masticatory muscles, mandibular range of motion, mandibular functional limitation, and occlusal discomfort. Data were analyzed with Doornik and Hansen, Shapiro-Wilk, and ANOVA at p=0.05. Results: All the variables showed significant improvement (p<0.05) from the first follow-up and were maintained later. BST control group, as well as groups with BST associated with OS, were able to reduce pain and increase the mandibular range of motion without significant differences between them (p>0.05), while the Thermoformed Tough-elastic splint was the most efficient in terms of the mandibular functional limitation. The occlusal discomfort decreased over time, but without statistically significant differences in terms of time and design of OS. Conclusion: The addition of thermoformed OS to behavioral and self-care therapy does not have a significant impact on myalgia of the masticatory muscles.
