Abstract

Introduction:This occlusal curvature is a naturally occurring phenomenon in the human dentition, describedin the late 19th century, by Ferdinand Graf von Spee. It is an inveterate parameter in describing ideal occlusion.The phenomenon still needs an immense understanding of its determinants to unravel all the aspects of its existence and the role that it plays in governing the other dental and skeletal variables.
Materials and Methods: A total of 107 patient pre-treatment records were selected. The lateral cephalograms and study models of the selected sample were thoroughly evaluated based on various skeletal and dental cephalometric and cast parameters. For the precision in the measurement of the depth of curve of Spee and thereby precise grouping, a computer based photographic method was employed for which a standardized photographic set-up was advocated.
Results: Statistically significant correlations were found between the depth of curve of Spee and overjet, lower incisor–NPg mm, lower incisor–NPg0, lower incisor–NB and Md-PABH measurements. Amongst these significant values Md-PABH, L1-NB, L1-MP, L1-NPg (0) and L1-NPg (mm) were negatively correlated and overjet was positively correlated.
Conclusions: It was deduced that Curve of Spee is more influenced dentally and to a minor extent by facial morphology.
