1 有床義歯装着後の咀嚼筋活動からみた順応過程に関する研究 (第439回 大阪歯科学会例会)

抄録

Using electromyograpy, I evaluated the adaptation of patients to recently placed dentures. Electromyograms (EMG) of the bilateral anterior temporal and masseter muscles were recorded in five patients together with mandibular kinesiograph (MKG) motions during mastication at the time of insertion of new dentures and for four weeks thereafter. The same recordings were made for patients who had dentures that had been in use for some time. EMG bursts during mastication were recorded before and after tooth contact, and duration and integrated values were measured. The results suggested that EMG time parameters and burst activities were effective factors in evaluating patient adaption to dentures.
