The objective was to determine the accuracy between functional swallowing (FS) and the Knebelman craniometric method (KCM) to measure occlusal vertical dimension (OVD) in total denture wearers.
A quasi-experimental, prospective study was conducted considering the KCM diagnostic method as the gold standard compared to FS. All the totally edentulous patients attended at the School of Dentistry of the Universidad Nacional Mayor de San Marcos ( = 32) in 2018-2019 were evaluated. Previous informed consent was obtained from all patients. A Knebelman's Craniometer was used to obtain longitudinal measurements measured in millimeters. The measurement was made with the Knebelman Craniometer by placing the tip into the external auditory canal inside the right meatus. On the other hand, for the FS method, the patients were seated comfortably with their back supported and their head in a natural position. Both upper and lower rollers were inserted into the mouth and the patient was instructed to swallow saliva for a period of 5min.
When comparing the measurement of the OVD of KCM versus FS according to sex, men presented an OVD of 68.1 ± 3.9 mm, being 64.1 ± 3.8 mm in women. Accuracy was evaluated with an analysis of concordance between FS and the KCM in the determination of OVD in totally edentulous patients with a value of 0.97 (confidence interval = 0.31-0.99) ( = 0.013).
There is a good concordance between the FS method and the KCM at the time of determining the OVD of edentulous patients using total prostheses.
本研究旨在确定在全口义齿佩戴者中，功能性吞咽法（FS）与克内贝尔曼颅骨测量法（KCM）测量咬合垂直距离（OVD）的准确性。
本研究为一项准实验性前瞻性研究，将KCM诊断方法作为与FS相比的金标准。对2018年至2019年在国立圣马科斯大学牙科学院就诊的所有无牙颌患者（n = 32）进行了评估。所有患者均获得了事先的知情同意。使用克内贝尔曼颅骨测量仪以毫米为单位进行纵向测量。使用克内贝尔曼颅骨测量仪进行测量时，将探头尖端放入右侧耳道内的外耳道。另一方面，对于FS法，患者舒适地就座，背部得到支撑，头部处于自然位置。将上下牙托插入口腔，指示患者吞咽唾液5分钟。
根据性别比较KCM和FS测量的OVD时，男性的OVD为68.1±3.9毫米，女性为64.1±3.8毫米。通过分析FS和KCM在确定无牙颌患者OVD时的一致性来评估准确性，其值为0.97（置信区间 = 0.31 - 0.99）（P = 0.013）。
在使用全口义齿确定无牙颌患者的OVD时，FS法和KCM之间具有良好的一致性。
