Chest x-ray (Fig. 1A) showed the dental crown lodged in the right bronchus intermedius. The handle operates in a similar manner to conventional biopsy forceps and deploys a one-sided fishnet-style mesh basket with an adjustable string collar that can be manipulated to enclose a target (Fig. 1B). The dental crown was successfully removed with the retrieval net on the second attempt (Fig. 1C); the size of the object necessitated the en bloc removal of the bronchoscope, retrieval net and crown.
