The mean intercanine distance was 16.7 mm on the right side and 16.9 mm on the left side, demonstrating strong bilateral symmetry (correlation coefficient = 0 . 859; p \u003C 0. 001) . Male participants had significantly higher measurements than females, with mean differences of approximately 1.15 mm, while no significant differences were observed across age groups. The overall mean value of 16.8 mm supports the clinical validity of this biometric measurement as a stable and accessible anatomical reference for determining occlusal vertical dimension in similar populations.  \nKeywords Occlusal vertical dimension, Biometric assessment, Prosthodontic planning  \nIntroduction  \nVertical dimension (VD) is defined as the distance between two selected anatomical or marked points, one on a fixed part and the other on a movable part [1]. This parameter, is fundamental in dental clinical practice because its alteration can compromise function and neuromuscular balance, as several studies have documented neuromuscular disorders associated with inadequate VD [2, 3]. Furthermore, changes in VD have been shown to  \n*Correspondence:  \nCristian Abad-Coronel  \n[cristian.abad@ucuenca.edu.ec](cristian.abad@ucuenca.edu.ec)  \n1Digital Dentistry and CAD/CAM Materials Research Group, Faculty of Dentistry, University of Cuenca, Cuenca, Ecuador  \n2Faculty of Dentistry, University of Cuenca, Cuenca, Ecuador  \nnegatively affect phonetics and masticatory efficiency, especially in edentulous patients undergoing prosthetic rehabilitation [4–6]. The aesthetic implications of reduced VD, including alterations in facial proportionsand smile line, have also been widely discussed in the literature [7–9]. Reduced VD is associated with masticatory muscle hyperactivity, altered occlusal forces, and temporomandibular disorders [10–12].  \nIn Latin American populations, where ethnic craniofacial variability — including mestizo, Indigenous, and Afro-Latin groups — may influence the applicability of vertical dimension parameters, recent genetic studies from Ecuador highlight a complex admixture pattern with variable craniofacial morphologies [13].  \n© The Author(s) 2025.
