The oral rehabilitation of the patients with partial or total edentulism with the use of dental implants has wide applications. In occasions, these applications are limited by anatomical and biological factors. Concretely, the posterior area of the maxilla can have a scarce height of residual ridge, besides a poor bony quality and further pneumatization of the maxillary sinus. All this makes that so much the conventional surgical technique as other alternatíve procedures as sinus lift, onlay graft, the technique with osteotoms and the osteotomy of Le Fort l, be surgical procedures that can change the anatomy and physiology of the maxillary sinus favoring the appearance of complications. One of the possible but rare complications is the displacement of the dental implants toward the maxillary sinus as the case that we describe in this article.
