An Anatomical Study of Maxillary-Zygomatic Complex Using Three-Dimensional Computerized Tomography-Based Zygomatic Implantation

Figure 4

The implant axis (IA) and its surrounding structures. Lines a and b in (a) represented the two planes vertical to IA in the 3D-CT image in (a). Line a went through the bone body of zygoma, while line b went through the maxillary sinus. (a) 3D-CT image of the head. (b) The plane that line a went through, showing the structures around IA in the zygoma. The marked point in the figure indicated IA. (c) The plane that line b went through, showing the position of IA and the maxillary sinus. The marked point in the figure indicated IA.
