Evaluation of craniometric methods for determination of vertical dimension of occlusion.
TL;DR: Although the N-Gn distance cannot be taken as absolutely reliable, owing to its simplicity and practical applicability it can be recommended for use in everyday clinical practice in combination with other methods for the determination of the vertical dimension of occlusion.
Abstract: In clinical practice, fully precise method for exact determination of vertical relation of occlusion still does not exist. This study examines the relationship between different craniofacial distances and the distance subnasale-gnathion (Sn-Gn), which represents the lower third of the face in vertical relation determination. The highest coefficient of correlation was (r = 0.8678, p < 0.05) between the distance eye-ear (E-E = lateral border of the ocular orbit-medial opening of the meatus of the external auditory canal) and Sn-Gn. The prediction of the distance Sn-Gn could be determined through the formula: Sn-Gn = E-E/1.08 or through the regression analysis: Sn-Gn = 1.9197 + 0.6449 x E-E. None of the calculated coefficients of correlation was 1, but was < 1, so that the prediction of the distance Sn-Gn by craniometric distances is not absolutely reliable, although it is considerably helpful. Our results point at the variations of craniofacial distances in the Croatian population. Yet, craniometry could still be recommended in everyday clinical practice for prediction of vertical relation of occlusion, as it is a simple, economic and non-invasive method, however in combination with some other methods, which have proved to be helpful.

TL;DR: In this article, the authors compared the pupil-rima oris distance with the occlusal vertical dimension (OVD) in Sundanese population and concluded that there was no significant difference between the two distances.
Abstract: Introduction: Among the most complex restorative challenges for a dentist is that related to determine the occlusal vertical dimension (OVD). Objective methods of determining the OVD offers significant advantages because no radiographs or other special measuring devices are required. Previous review said that the OVD is similar to the pupil-rima oris distance among the population of India. The purpose of this study was to compare whether there was differences between the OVD and the pupil-rima oris distance among Sundanese population. Method: This study was an analytical cross sectional approach. A total of fifty Sundanese students of Faculty of Dentistry, Universitas Padjadjaran who have fulfilled all criteria were chosen randomly to be measured the OVD and the pupil-rima oris distance. Result: Results showed that there was no significant difference between the OVD and the pupil-rima oris distance (α=5%). There were strong correlations between the OVD and the pupil-rima oris distance (p<0.05). An analysed with Spearman’s rank correlation statistic (α=5%) reveals that there was a significant difference between males and females in the OVD and the pupil-rima oris distance. Conclusion : Based on the analysed data, we can conclude that there wass no significant difference between the OVD and the pupil-rima oris distance, thus, the pupil-rima oris distance can be suggested as an objective method to determine the length of OVD in Sundanese population.

TL;DR: The aim of this study was to find out the anthropometric correlation of vertical dimension of occlusion (VDO) with the length of ear, nose, and little finger in dentate male and female subjects in Karad population so as to use this correlation to determine VDO in edentulous patients.

TL;DR: In the limits of the study, the facial scanning could be used for predictable registration of OVD and the stored digital information could be preserved through life and use for oral rehabilitation.
Abstract: (1) Background: Occlusal vertical dimension (OVD) in the optimal maxillo–mandibular relationship is an important parameter to establish when complex dental rehabilitation has to be done. The optimal method to measure OVD is still a challenge in everyday practice. The aim of the present study was to test the reliability of the correlation between OVD and some anthropometric and cephalometric methods described in the literature. The validity of OVD registration using a facial scanner was also assessed. (2) Materials and Methods: 150 dentate participants, aged 20–25 years, were randomly selected using sealed envelopes. Anthropometric measurements between specific standard points were performed: Subnasion–Prementon (Sn–PM) and Subnasion–Gnation (Sn–Gn) in maximum intercuspation and in the rest mandibular position, right and left pupil to the corresponding chelion. The cephalometric measurements registered were the lower facial angle and the angle between mandibular and Frankfurt planes. The distance Sn–Gn in maximum intercuspation was compared to all other parameters. Facial scanning, with a mobile phone and installed dedicated application, was performed on ten subjects, randomly selected using the same method among the participants, and the obtained 3D files were analyzed. The digital measurements were compared, for validity, to the clinical measurements. Pearson’s correlation coefficient was used, for comparing clinical Sn–Gn in maximum intercuspation position to the other parameters. (3) Results: A strong agreement between all measured anthropometric parameters of the facial scan and clinical contact measurement method was registered. None of the measured parameters could predict the exact OVD. (4) Conclusions: In the limits of our study, the facial scanning could be used for predictable registration of OVD and the stored digital information could be preserved through life and use for oral rehabilitation. However, if OVD needs to be determined, several measurement methods, including cephalometric measurements, need to be used simultaneously to reach a final decision.
