Applications of Cone Beam Computed Tomography in Orthodontics: An Overview

Abstract

Cone beam computerized tomography (CBCT) has changed numerous aspects of dentistry and added great value to its diagnostic phase also as that of orthodontics. Three-dimensional imaging CBCT has the potential to improve the diagnosis and treatment planning of cases. The introduction of cone beam computerized tomography (CBCT) technology to dentistry and orthodontics revolutionized the diagnosis, treatment and monitoring of orthodontic patients. The information obtained from CBCT imaging provides several substantial advantages. For example, CBCT imaging provides accurate measurements, improves localization of impacted teeth, provides visualization of airway abnormalities, it identifies and quantifies asymmetry, it are often wont to assess periodontal structures, to spot endodontic problems, to plan placement sites for temporary skeletal anchorage devices, and to look at condylar positions and mandibular joint (TMJ). Moreover, CBCT imaging involves only a minimal increase in radiation dose relative to combined diagnostic modern digital panoramic and cephalometric imaging. Cone-beam computed tomography (CBCT) is now being widely used in orthodontic practice. On the one hand, there is an increasing need of CBCT for diagnosis and research, and on the other hand, there is a broad concern for the exposure to radiation. Prescribing CBCT scan requires judicious clinical judgment to maximize the benefits and minimize the harm. The best way to reduce unnecessary ionizing radiation from CBCT is to follow recommended guidelines and ethical principles. CBCT provides a superb tool for accurate diagnosis, more predictable treatment planning, more efficient patient management and education, improved treatment outcome and patient satisfaction. This review discusses the utilization of CBCT in diagnosis and treatment planning in orthodontics.
