C302 – USDI Contemporary Cephalometric Analysis

INSTRUCTOR: Dr. Viet Ngheim

December 4, 2022 @ 8:00 am 2:30 pm

This is a Cephalometric course which includes a detailed evaluation of the definitions of landmarks, tracing of head plates, and a review of Steiner and the USDI’s systems of analysis. A brief history of cephalometrics, structures of the skull and landmarks will also be discussed.  Constructing the USDI analysis and the measurements needed will be examined. Model analysis which is the first and foremost adjunct to Cephalometrics will also be reviewed.  Measurements are performed on models of each case to determine the Arch Form, Arch Width and Arch Depth.  The arch form is assessed as Roman (IDEAL), Gothic or Truncated.  The arch width and the arch depth is then measured.  Each value is compared to IDEAL for an individual patient using the appropriate forms to compile the information.  These are the first steps in the DIAGNOSIS of a case.

After the completion of this course the Participant will understand:

  • The importance of cephalometrics analysis
  • Basic Orthodontic cephalometrics classifications and definitions
  • Model analysis, Arch Form, Arch Width and Arch Depth definitions and measurements
