Effect of resilient liners on masticatory muscle activity of edentulous patients: clinical and electromyography studies.
This investigation evaluated how the soft lining of both maxillary and mandibular complete dentures influences the activity of the masseter and temporalis muscles. Electromyography was used to determine changes in muscle activity. The findings, expressed by Root Mean Square values, indicated an increase in muscle activity after insertion of dentures and prior to application of soft lining material. These activities decreased gradually throughout the 12-week evaluation period following the application of soft liner. Significant differences were noted between masseter and temporalis muscle activity during mastication of different types of food.
