Impact of Implant Supported Overdenture on Changes of Electromyographic and Brain Activity

"Impact of Mandibular Implant Supported Overdenture on Changes of Electromyographic Activity, Brain Activity, Cognitive Function, Nutrition and Depression Status."

The purpose of this study is to evaluate and compare the effects of a mandibular implant-supported overdenture with a mandibular complete denture on electromyographic activity, brain activity, and cognitive performance in edentulous patients. Ten patients who are entirely edentulous and did not wear dentures will be chosen. To assess brain activity and cognitive function, electroencephalograms, the Mini-Mental State Examination (MMSE), and electromyographic examinations of the temporalis and masseter muscles will be performed prior to complete denture construction, one and three months after complete denture construction, and one and three months after implant supported overdenture insertion, respectively.

Inclusion Criteria:

• All patients' ridges should be covered with firm mucosa which is free from any signs of inflammation or ulceration.
• Patients should be free from any bone disorder and exhibit adequate height and width of the residual alveolar ridge.
• All patients must have sufficient inter arch space.

Exclusion Criteria:

• Patients with oral or systemic diseases.
• Patients with xerostomia or excessive salivation.
• Patients with parafunctional habits (bruxism or clenching).
• Heavy smoker or alcoholic patients.
• Patients with history of temporo-mandibular dysfunction.
• Patients with neurological or psychiatric disorders.
