Cephalometric evaluation of different methods for recording denture position

In the follow up studies, it was recommended to use cephalometric X-ray technique to study the changes of denture position. It was advised, according to the results, to follow the light contact condition technique in keeping the upper denture in place during successive exposures

study on the effect of lower denture weight on the action potential of masseter and temporalis muscles

To study the effect of increasing the weight of the lower denture on the action potential of the masseter and temporalis muscles, 10 complete denture wearers were selected complaining of unstable lower denture. Electromyographic recording in different functional situations were done for each patient with their original denture. The weight of the lower denture was doubled and delivered to the patient to use it for three weeks. Another electromyographic recordings in the same functional situations were recorded with modified denture. From the obtained results it was concluded that, increasing weight of the lower denture affects the action potential of the masseter and temporalis muscles. Besides, increasing weight of lower denture increases muscular activity of temporalis and masseter muscles. Finally, increasing weight of the lower denture improves denture service and patient's comfort
