This essay is intended as an outline and brief introduction to investigations in the area of integrated three-dimensional (3D) craniofacial measurement currently in progress at the University of the Pacific School of Dentistry, and to demystify some of the underlying principles. We address the following questions:
After the treatment of these questions, a series of movies of a representative case are shown. Alternatively, the reader may use this index page to jump directly to the movies or to the discussion of any question of choice by clicking linked (underlined) words.
- Question 1: Why should orthodontists be interested in 3D craniofacial measurement?
- Question 2: What is the basic principle underlying non-contact 3D measurement from images?
- Question 3: How can one obtain 3D information about structures in the skull obtained from 2D projection images?
- Question 4: How is 3D information about the surface of the face obtained?
- Question 5: How is 3D information about tooth size and arch form obtained?
- Question 6: How do we merge 3D maps of the skull, face, and teeth?
- Clinical Implementation
