Accidental aspiration in a patient with Parkinson's disease during implant-supported prosthesis construction: a case report

This article reports on a case history of an elderly patient with Parkinson's disease (PD) who sought treatment at a private dental office. His chief complaint was "difficulty in eating due to an illfitting prosthesis." Laboratory tests and oral radiographs were made. The surgical placement of an implant was done and, subsequently, an implant-supported prosthesis was fitted for the patient. During the impression for the construction of the implant-supported prosthesis, the patient accidentally aspirated the implant screwdriver. The object was found in the lower right lobe of the bronchus, and its removal was necessary in a hospital using bronchoscopy under general anesthesia. Patients with PD are considered at risk of aspirating and/or ingesting dental instruments. Short treatment periods are recommended, preferably during the morning, when the medication prescribed for PD is most effective. When treating patients who have a risk for aspirating and ingesting small objects, it is important to treat them in a more vertical position, and small-sized objects should be secured with dental floss to aid retrieval.
