INTRODUCTION: Cone-Beam Computed Tomography (CBCT) was introduced in the 90's and studies have improved its use in dentistry. OBJECTIVE: The aim of this article was to investigate the influence of three-dimensional (3D) images in orthodontic treatment planning. METHOD: Two clinical situations (bone dehiscence and cervical resorption) were described by 3D images. RESULTS: The orthodontic treatment plan was redirected to a simplified mechanics and control of the lesions during orthodontic treatment. CONCLUSION: 3D images are able to increase diagnostic accuracy and redirect orthodontic treatment plan.
