Expanding the Scope of Cephalometrics with Shape Analysis

Orthodontists have relied heavily on cephalometric analysis, although shortcomings of using linear and angular measurements are well known. A new area of analysis, which examines the shape of objects, has been increasingly used to help clinicians determine more accurate diagnoses as well as identify factors that contribute to treatment outcomes. This presentation will describe how shape analysis is done, and give some examples of how it is currently used in orthodontic diagnosis.

Learning Objectives:

• Recognize the shortcomings of linear and angular cephalometric measurements and recognize the value of shape analysis.
• Identify the steps in shape analysis.
• Describe clinical situations where shape analysis can be helpful.
