对17名正常人和单纯性深覆患者的息止间隙(FS)及13名重度深覆伴牙列缺损患者用垫式义齿修复前后的FS、肌肉功能状态及咀嚼效率进行了比较。单纯性深覆患者的FS小于正常人(1.57±0.56mm,2.00±0.43mm,P<0.05)。戴上修复体后形成了新的FS,增加的垂直距离未引起肌肉疲劳,并使肌肉的收缩功能有所改善,咀嚼效率明显提高,说明修复体是成功的,深覆患者的下颌姿势位有一定的适应范围。
The FS and muscle functional status and masticatory efficiency in 17 normal and simple deep-covered patients before and after the rest of flexion and gap reduction (FS) and 13 patients with severe deep over-dentate denture defect Compare The FS of patients with simple deep overburden was less than that of normal controls (1.57 ± 0.56mm, 2.00 ± 0.43mm, P <0.05). Put on the restoration after the formation of a new FS, increase the vertical distance of the 未 did not cause muscle fatigue, and muscle contraction function improved, chewing efficiency was significantly improved, indicating that the prosthesis is successful, deep patients jaw posture There is a certain degree of adaptation.
