Multiplanar reconstructions from the axial and coronal planes confirmed that the patient had an impacted third molar with curved roots and supernumerary tooth located superiorly to the third molar (Figure 1, 2).

To determine the position of the tooth, another set of PANO (Figure 3) and CBCT imaging (Figure 4a, b) was obtained which clearly showed that the tooth has been displaced into the ITF and positioned medially to coronoid notch between the lateral wall of the maxillary sinus and the zygomatic arch (Figure 5).
