| Abstract | ||
| Objective: to evaluate the effect of two techniques of denture construction on the muscle activity using electromyography the occlusal load using T-scan. Materials and method: Twenty completely edentulous patients were selected and allocated into two groups: Group I: The upper and lower denture were processed in the usual manner and delivered to the patient. Group II: The upper waxed denture we processed only then remounted against the waxed lower denture any occlusal adjustment was done in the lower waxed denture then the processing the lower denture was performed - Electromyography recording were performed with the patient seated in relaxed upright position. -Electromyography recording device was used to evaluate the action potential of the masseter and anterior fibers of temporalis muscle. -The T-scan III was used for bite force measurement to detect the location, timing and magnitude of occlusal forces. Results: There was statistically significant difference between both groups during chewing soft and hard food diet for masseter and temporal is muscles. The highest mean differences muscle activity were recorded for patients received conventional denture while the lowest values recorded for patients received denture in muscle activity of group II. Conclusion: The Schlosser’s technique is considered as predictable methods of complete denture construction. The more harmonious occlusion result from this technique results in an improvement of the muscle activity and biting force. | ||
