Abstract

Cephalometric analysis has been a key element in the diagnosis and treatment planning in orthodontics and orthognathic surgery; however, it has suffered from inherent drawbacks such as magnification, superimposition of anatomical structures and presentation of a two-dimensional (2D) projection of a three-dimensional (3D) object. With the advent of cone-beam computed tomography (CBCT), the 3D analysis presented a promising approach to overcome all the traditional cephalometric disadvantages. Several software developers have offered 3D digitizing systems. In this chapter, authors introduced new landmarks, planes and measurements to accurately evaluate the relationships among skeletal and dental structures. Special attention was paid to the midfacial area and other features that cannot be evaluated in 2D. © 2013 Nova Science Publishers, Inc. All rights reserved.
