3D orthodontic and surgical study of third molars: MRI vs CBCT

The aim is to assess 3D volumetric anatomical reconstruction of the third molars and the relationships with the Inferior Alveolar Nerve canal (IAN) by Magnetic Resonance Imaging (MRI) versus Cone Beam Computed Tomography (CBCT). The precise localization of third molars and the study of their relationships with the Inferior Alveolar Nerve canal (IAN) is critical for a correct surgical approach. Magnetic Resonance Imaging (MRI) is a technique applied in various branches of medicine, it allows to obtain tissue images using a high intensity magnetic field. The volumetric MRI has resulted optimal for the virtual models of anatomical structures, especially the third molars and the IAN. The results presented confirm the possibility of using this MRI technique for imaging 3D-volumetric study of dental and maxillo-mandibular structures.
