A patient who presented with the complaint of a gap between her upper and lower teeth on biting, reveals a skeletal open bite on cephalometric analysis. Who developed the cephalometric analysis that was used for the diagnosis of this patient?
Correct Answer: Sassouni
Description: The Sassouni analysis given by Viken Sassouni, was the first cephalometric method to emphasize vertical as well as horizontal relationships and the interaction between vertical and horizontal proportions.
Sassouni pointed out that the horizontal anatomic planes-the inclination of the anterior cranial base, Frankfort plane, palatal plane, occlusal plane, and mandibular plane-tend to converge toward a single point in well-proportioned faces.
If the planes intersect relatively close to the face and diverge quickly as they pass anteriorly, the facial proportions are long anteriorly and short posteriorly, which predisposes the individual to an open bite malocclusion. Sassouni coined the term skeletal open bite for this anatomic relationship.
If the planes are nearly parallel, so that they converge far behind the face and diverge only slowly as they pass anteriorly, there is a skeletal predisposition toward anterior deep bite, and the condition is termed skeletal deep bite.
