Ingestion of mandibular complete denture.

A broken mandibular denture was accidentally swallowed by a mentally incompetent patient. Dentists and nursing staff must be aware of the problems encountered in the care of such patients who wear removable dental prostheses. To aid in radiologic diagnosis, an opaque disk or foil should be used in the construction of an acrylic or plastic dental prosthesis. All removable dental prostheses should have additional patient identification that can be easily detected in radiographs.
