Extraordinary sneeze: Spontaneous transmaxillary-transnasal discharge of a migrated dental implant

Figure 1 The preoperative panoramic radiography showed an unknown disappearance of an upper endosseous dental implant previously located in the posterior aspect of the right upper maxilla.

Figure 2 Coronal computed tomography scan clearly revealed the dental implant located in the upper third of the maxillary sinus. Acute maxillary sinusitis and ethmoiditis are evident.

Figure 3 Axial computed tomography scan allowed to analyze the exact position of the implant between the maxillary sinus interiorly and the osteomeatal complex posteriorly.

Figure 4 The sneezed implant. The prosthetic abutment is still engaged to the dental implant.
