Part 1 | Planes & Arcs: Sassouni Plus Archial Analysis

In this four-part series, we will take a deep dive into the Sassouni Plus Analysis.2 This first part will describe the 7 planes and 8 arcs that make up the Sassouni Archial Analysis, as well as Locus O and determining its position. This may seem academic and boring, but it is necessary for the reader to understand the planes and arcs to be able to apply them when diagnosing and treatment planning an orthodontic case.

The Sassouni Plus Analysis (Fig. 1) is an orthodontic analysis that relates the patient’s anatomical structures to each other within the framework of the individual patient. The Cephalometric Bottom Line does have some numerical norms, but most of the analysis is based on the patient’s skeletal landmarks as they relate to one another.

The original Sassouni Archial Analysis was conceived by Dr. Viken Sassouni3 in 1955. Dr. Sassouni had degrees in both orthodontics and anthropology. He combined his anthropological background with knowledge of craniometricians that came before him and applied it to the discipline of orthodontics. He believed that no one cephalometric baseline or angle remained consistent enough to serve as a basis of comparison for all individuals.
