Imaging in orthodontics: Using cone beam computed tomography to identify growth disturbances affecting the airway, temporomandibular joints and systemic health

Abstract

Cone beam computed tomography (CBCT) is a 3-dimensional radiographic technique adopted by the dental profession in the early 2000′s. This technology opened up a world of information with respect to anatomy, pathology and treatment planning as practitioners would now be able to analyze the maxillofacial complex in all 3 planes.The specialty of orthodontics gained significant tools with the application of CBCT for evaluating the orthodontic patient. In the area of craniofacial growth, CBCT allows for the evaluation, diagnosis and follow-up of normal growth and deviations from normal. With the opportunity for early detection of growth disturbances also comes the ability to Identify serious health problems. The following review is how to use CBCT images and tools to evaluate for growth disturbances with focus on the temporomandibular joints and the upper airway.
