Analysis of coherence between Vertical Dimension of Occlusion (VDO) obtained clinically and through cephalometric analysis. A cross-sectional study

Abstract

Abstract Introduction Determining the VDO is one of the most important requirements in restorative dentistry, as it is crucial for good aesthetic and functional harmony. However, due to its empirical nature, a combination of methods is clinically recommended, and cephalometric analysis is one of the procedures available. Objective The objective of this study is to evaluate the coherence between VDO clinically established with VDO determined in Seraidarian-Tavano cephalometric analysis in completely edentulous patients. Material and method Registrations were carried out on completely edentulous patients using a combination of clinically recommended methods (metric method from VDR, swallowing method, and facial fullness method). With the registration in the mouth, lateral cephalometric X-ray images were taken with the patient in occlusion for cephalometric analysis. Result The sample consisted of 18 patients, 11 females (61.1%) and 7 males (38.9%) with a mean age of 65.8 ± 1.9 years. For the 18 patients, the mean measurements of the upper and middle angles were 54.1 and 54.0, respectively. No statistically significant difference was found between the two angles (p 0.772). These results show that the VDO considered ideal from a clinical point of view was confirmed by the cephalometric analysis used. Conclusion Based on the data, it seems fair to conclude that the tested cephalometric analysis can be a method used to assist the clinical determination of VDO.
