简要总结
This study aims to evaluate masticatory efficiency of the zero-degree teeth complete denture in treatment of edentulous patients of severely resorbed ridge.Patients will be crossed over to be treated with zero-degree teeth complete denture and anatomic teeth complete denture. For each patient, the masticatory efficiency and electromyography with different denture will be recorded and analysis.

结局指标
主要结局
EMG (Masseters EMG Are Recorded After Patient Wears Complete Denture for Three Months)
时间窗: three month
the masseters EMG are recorded after patient wears complete denture for three months,EMGs of masseters of 20 chewing strokes were recorded in term of value of amp and duration, duration here is reporteds the average value from 20 chewing strokes in units of "millisecond".
次要结局
- Masticatory Efficiency Index(three months)
