Aplicação da tomografia computadorizada de feixe cônico na ortodontia

Abstract

Cone-Beam Computed Tomography (CBCT) represents a significant technological advancement in dentistry, particularly in orthodontics, by providing precise threedimensional images of the dentomaxillofacial structures. This study aimed to analyze, through a narrative literature review, the main clinical applications, advantages, limitations, and ethical implications associated with the use of CBCT. The research was conducted in the PubMed, SciELO, ScienceDirect, and Google Scholar databases, including articles published between 2015 and 2025 in Portuguese and English. The analysis showed that CBCT overcomes the limitations of conventional radiographic methods, allowing for more detailed diagnoses, more accurate surgical and orthodontic planning, and integration with digital technologies such as planning software, intraoral scanning, and three-dimensional printing. However, its use must follow strict ethical and technical criteria, considering radiation exposure, examination cost, and the need for professional training. It is concluded that CBCT, when used judiciously, is an essential tool in modern orthodontic practice, contributing to safer diagnoses and more effective treatments.
