Abstract
Twenty six completely edentulous patients were selected from the outpatient clinic of the Prosthodontic Department, Faculty of Oral and Dental Medicine, Cairo University according to certain criteria.
Patients were divided randomly into two equal groups:
Group I: patients wearing conventional heat cured acrylic complete denture.
Group II: patients wearing conventional heat cured acrylic complete denture relined by soft acrylic versacryl.
Chewing efficiency and Electromyography records taken for both groups at time of insertion, after first, second and third month.
The data was tabulated and statistically analyzed and the following were resulted:
1) Electromyographically:
1. EMG activity, of both the masseter and temporalis muscles, increased after the relining the complete denture with soft liner (versacryl).
2. EMG activity of the masseter muscle was higher than the temporalis muscle in both groups.
2) Chewing efficiency:
- Decreased time taken during swallowing while patient wear complete dentures lined with soft acrylic versacryl than conventional complete dentures.
