Ricketts Analysis
A cephalometric analysis system developed by Robert Ricketts that uses specific craniofacial landmarks to assess skeletal, dental, and soft-tissue relationships.
Full Definition
Ricketts Analysis is a systematic method of evaluating lateral cephalometric radiographs using a defined set of planes, angles, and linear measurements attributed to orthodontist Robert Ricketts. It includes assessments such as the E-plane (aesthetic plane) for soft-tissue profile evaluation and facial axis measurement for growth prediction. Editors encounter references to this analysis in research articles, case reports, and postgraduate theses. It should always be capitalised as a proper noun. Editors must not conflate it with the Steiner Analysis or Tweed Analysis, which are alternative cephalometric methods with different landmark sets.
Usage
Usage note: Always capitalise as a proper noun. Confirm with authors which cephalometric analysis system is intended when multiple methods are referenced.
