Purpose: The loss of natural teeth leads to bone resorption and muscular hypotonicity, which may affect the structures involved in mastication.Atrophy of supporting tissues, poor adaptation, reduced masticatory efficiency, and psychosocial embarrassment are major complaints of edentulous patient wearing old/faulty denture. The need for this study is to examine the effect of old/faulty dentures and a new denture on the masticatory muscle efficiency with the help of electromyography. Materials and methods: 15 edentulous patients wearing complete denture prosthesis selected as a subject for the investigation. Surface electrodes from electromyographic unit were placed in the region of right and left anterior Temporalis muscle and Masseter muscle, and the patients will be asked to perform maximum voluntary contraction. The muscle activity analyzed twice for each patient: (1) with the old/faulty dentures and (2) 5 month following insertion of new denture. Results: The electrical activity during maximum voluntary contraction exhibited statistically significant improved muscle efficiency with new denture when compared to those with old dentures in place for 5 months. Conclusion: New dentures or improvements in occlusion and vertical dimension produce a positive benefit to the patient by reducing the muscle effort during chewing without affecting masticatory performances. The reduction in muscle effort is likely to cause less tissue and in the end may minimize residual ridge resorption and new complete denture allows for neuromuscular reprogramming, which contributes to muscular balance of the masticatory system.
