摘要

目的:本研究的目的是评价语音法在全口义齿构建中确定咬合垂直尺寸的方法与其他垂直尺寸法和咬合环高度法的比较。研究对象和方法:15例全牙无牙患者,年龄40 ~ 60岁,平均年龄54.40岁。采用语音法、生理休息位法和咬合缘高度法三种不同的方法测量咬合垂直尺寸(VDO)。调整上牙合缘高度和方位后,用上颌面弓将上牙合模安装在半可调关节器上,记录中心关系并安装下牙合模。在关节器上测量三种方法的平均弓间距离(IAD)。将结果制成表格并进行统计分析。结果:三种方法测得的平均弓间距离差异无统计学意义。此外,两种方法之间存在显著的正相关。结论:语音法测量OVD比生理休息位法更可靠。牙合边缘高度法被认为是令人鼓舞的,但必须通过对更大样本患者的进一步调查来证实。

Evaluation of the phonetic method for determining the vertical dimension of occlusion in complete denture construction
Objectives : The purpose of the present study was to evaluate the phonetic method for determining the vertical dimension of occlusion in complete denture construction as compared to the rest vertical dimension method and the height of occlusal rim method. Subjects and methods : Fifteen completely edentulous patients were involved in the study, patients age ranged between 40-60 years with a mean age of 54.40 years. Vertical Dimension of Occlusion (VDO) was measured using three different methods, phonetic method, physiologic rest position and height of occlusal rim method. The upper cast was mounted on a semi-adjustable articulator using the maxillary face bow, after adjustment of upper occlusal rim height and orientation, followed by centric relation recording and mounting of the lower cast. The mean inter- arch distance (IAD) of the three methods were measured on the articulator. The results were tabulated and statistically analyzed. Results: There was statistically no significant difference in the mean Inter-arch distance measured by the three mentioned methods. As well as, significantly positive correlation was found between the methods. Conclusion: Phonetic method was more reliable method than the physiologic rest position method in measuring the OVD. The heightof occlusal rim method considered encouraging but must be confirmed by further investigations on larger sample of patients.
