3D analysis and clinical applications of CBCT images

Abstract

Cone-beam computed tomography (CBCT) images is an essential element in diagnosing and treatment planning patients in need of orthodontic and/or orthognathic surgery. An accurate evaluation of the dental, skeletal, and soft-tissue relationships through the normative values of three-dimensional (3D) cephalometric parameters, specifically palatal and alveolar bone thickness, mandibular body and maxillary basal curve length, and basal arch form have been demanded. The normative values of innovative 3D cephalometric parameters for palatal bone thickness in adolescents versus adults may be helpful for clinicians to enhance the success in application and use of temporary skeletal anchorage devices. Characteristics of alveolar bone thickness, basal arch form, and facial asymmetry of both normal occlusion and Class III malocclusion are also discussed with 3D CBCT images. In this article, the various 3D analyses and clinical applications including bone thickness, facial asymmetry, basal curve length, and basal arch form are addressed.
