The aim of the study was to explore, using a mathematical function developed with the aid of a geometric design, the relation between the condylar pathway and the occlusal plane, defined as the convergence angle. Applying a trigonometric function that considered the value of the convergence angle, the minimum distance between a specific point in the condyle and the lower incisor point , and the distance covered by the condyle during the mandibular movement, we studied the direct proportionality between the value of this angle and the angle of disclusion of the posterior teeth in Christensen's phenomenon. Finally we compared the mathematical evaluations withfindings in several clinical cases, obtaining good agreement of results.

Abstract
The aim of the study was to explore, using a mathematical function developed with the aid of a geometric design, the relation between the condylar pathway and the occlusal plane, defined as the convergence angle. Applying a trigonometric function that considered the value of the convergence angle, the minimum distance between a specific point in the condyle and the lower incisor point , and the distance covered by the condyle during the mandibular movement, we studied the direct proportionality between the value of this angle and the angle of disclusion of the posterior teeth in Christensen's phenomenon. Finally we compared the mathematical evaluations withfindings in several clinical cases, obtaining good agreement of results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
