Three-dimensional digital modeling and setup.

ABSTRACT

Obtaining accurate images of the craniofacial region is critical when developing an orthodontic diagnosis and treatment plan. The purpose of this article is to describe a new imaging method that provides complete 3-dimensional views of the maxilla and the mandible, and the model setup with individual anatomic roots. The method uses computed tomography technology and laser scanning; it offers high-resolution images with relatively low radiation exposure. Technical aspects of the new procedure and its possible uses for orthodontic diagnosis and treatment planning are discussed.
