This case report describes the management of a lesion involving the Canalis Sinuosus (CS), that is a bone channel originating from the infraorbital canal below the orbital margin and posterior to the infraorbital foramen and coursing in an anterolateral direction to the anterior wall of the nasal cavity. A female patient, 62y, ASA 1, wearing full mobile dentures, came to our clinic asking for upper jaw rehabilitation. Due to a severe bone atrophy, a graft procedure was performed and the placement of eight implants was planned. One week after implants were positioned, the patient referred pain in the upper right central incisor region, that was compatible with a normal post-operative healing. After 15 days, since the symptoms worsened and became localized and persistent, a more detailed CBCT analysis was carried out. The images demonstrated that a CS on the right side was compressed by the apex of the implant in position #11. The implant was replaced with a shorter one and adequate pharmacological therapy was prescribed. All the symptoms completely disappeared after 30 days.
