Impact of Implant Supported Overdenture on Changes of Electromyographic and Brain Activity
Study Details
Study Description
Brief Summary
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.

Outcome Measures
Primary Outcome Measures
- Brain Activity (EEG) [3 months]
An assessment of the patient's brain activity will be done. The waves obtained during all phases of assessment will be analyzed, and the software will separate the alpha waves, which occur in the frequency range of 8-12 Hz, evaluating their amplitude. The mean amplitude (in microvolts) of alpha waves was obtained.
Secondary Outcome Measures
- Cognitive Function (MMSE) [3 months]
Cognitive function will be assessed using the Mini-Mental State Examination (MMSE) questionnaire. The MMSE set, with a total score of 30, assesses different domains of cognitive function. The MMSE comprises 30 questions, with 10 devoted to orientation; three items requiring registration of new information; five questions addressing attention and calculation; three recall items; eight items assessing language skills; and one construction question. Any score of 24 or more (out of 30) indicates normal cognition. Scores below this indicate severe (9 points), moderate (10-18 points), or mild (19-23 points) cognitive impairment.
Other Outcome Measures
- Muscle Activity (EMG) [3 months]
The highest EMG activity in the masseter muscle and the anterior temporalis muscle will be calculated during the maximum clenching, maximal voluntary contraction (MVC) in the intercuspal position. The EMG signals will be stored and analyzed as root mean square (RMS) values expressed in microvolts (μV) and the mean amplitude of the motor unit potential (MUP) will be calculated in microvolts (μV).
