Abstract
Purpose: To evaluate in-vivo the effect of CAD/CAM constructed dentures on the masticatory muscles activity using electromyography in comparison to conventionally constructed dentures.
Materials and Methods: Fourteen completely edentulous patients were randomly allocated to two equal groups. Patients in the first group received conventionally constructed complete dentures and patients in the second group received complete dentures constructed using CAD/CAM technology. After 30 days of denture use the anterior temporalis and superficial masseter muscles activity were measured by EMG. A cross over was performed for patients with conventional denture to CAD/CAM and vice versa and the dentures were used for further 30 days, after which measurements of anterior temporalis and superficial masseter muscles activity were taken using EMG. Electromyographic data was recorded and analyzed, mean values were compared by independent t-test to compare between the two groups as regard to muscle activity.
Results: There was a significant difference in the activity of the masseter muscles and the anterior temporalis muscles for the patients received CAD/CAM denture in comparison to those received the conventional denture, after 30 days of denture use (p < 0.05).
Conclusion: CAD/CAM constructed complete dentures produced higher muscle activity if compared to conventionally constructed complete dentures.
