We have encountered a rare case in which the subject underwent maxillary sinus floor elevation at another hospital, and a screw to fix the grafted bone substitute was forced into the maxillary sinus and intruded into the bone. Various different foreign bodies have been reported as being forced into the maxillary sinus due to dental treatment, and these foreign bodies are often retained on the maxillary sinus mucous membrane. However, no reports have described a screw forced in and intruded into the peculiar position in the bone, as seen in the present case, which we report here with additional discussion.
