The aim of the present study was to determine the changes in masseter muscle thickness due to the state of complete edentulism and the effect of complete denture rehabilitation on the masseter muscle.
Real-time ultrasonography of the masseter muscle at relaxed and contracted states was carried out for twelve patients (six dentulous and six completely edentulous). Edentulous patients were scanned at the time of denture insertion and at the end of 3 months' follow up.
The mean masseter muscle thickness of the edentulous patients was significantly increased after the 3-month follow-up than the thickness at the time of denture insertion, but was significantly lower than that of the dentulous patients of the same age group.
Within the limitations of this study, it can be concluded that change occurs in the masseter muscle thickness after rehabilitation with complete dentures in the form of increased muscle thickness. However, the thickness of the muscle remains smaller than that of dentate individuals.
本研究的目的是确定全口无牙状态导致的咬肌厚度变化以及全口义齿修复对咬肌的影响。
对12名患者（6名有牙颌和6名全口无牙颌）的咬肌在放松和收缩状态下进行实时超声检查。无牙颌患者在义齿佩戴时和随访3个月结束时进行扫描。
无牙颌患者在随访3个月后的咬肌平均厚度比义齿佩戴时显著增加，但明显低于同年龄组有牙颌患者的咬肌厚度。
在本研究的局限性范围内，可以得出结论，全口义齿修复后咬肌厚度会发生变化，表现为肌肉厚度增加。然而，该肌肉的厚度仍小于有牙个体的厚度。
