초록
Purpose: Dental implant displacement into the maxillary sinus can be performed intraoperatively, during the healing phase and after loading. We aimed to describe the etiology, sequela, and treatment in each stage by presenting 27 sinus migration cases. Conclusion: Implant displacement was predominant during the healing period and for the osteotome technique. Unnoticed membrane perforation during implant placement in the posterior maxilla may cause dental implant displacement into the maxillary sinus. Osteotome sinus floor elevation should be utilized carefully to prevent implant migration. The lateral approach with endoscope visualization facilitated displaced implant removal.
