Abstract
The masticatory function of patient with Brånemark implant in edentulous mandible was evaluated by electromyography (EMG), mandibular movement (MKG), and bite force. EMG and MKG during gum chewing and bite force in clenching were recorded at insertion of the old full denture and at 1 week, 2 months, 2.5 months, 3 months and 4 months after insertion of implant bridge.
The time parameter (duration and interval) of EMG burst was changed slightly, but the mean value of mean voltage was increased and CV became stable.
The chewing route showed decreased lateral deviation and improved reproducibility.
Bite force was increased greatly.
These results suggested that evaluation of function of implant bridge could require defined data and original parameter.
