Canalis Sinuosus and radiographic procedures in the region of anterior maxilla

The Canalis Sinuosus (CS) is known as an anatomical variation of anterior superior alveolar nerve being a neurovascular bundle. Frequently, the anterior maxillary region receives surgical interventions of different specialties. The knowledge concerning anatomical structures in this region, is crucial to reach predictable and safe surgical procedures. The overlapping of anatomical structures in conventional imaging examinations have a limit in observing neurovascular canal, such as the CS. Thus, Cone Beam Computed Tomography (CBCT) images may give a great support in preoperative planning, since it allows the three-dimensional reconstruction of the anatomical details of its structures. In this report, the author describes an implant rehabilitation that may have possibly injured the anterior superior alveolar nerve.
