Modified reharmann flap – A novel flap technique for root retrieval from maxillary sinus

The aim of this study was to describe the standard diagnostic procedure and the application of the Caldwell-Luc approach for the retrieval of a displaced root from the maxillary sinus and to share our experience in treating this complication. We Demonstrate a modified Reharmann flap that can be used for both retrieval of root as well as can be used to advance the buccal flap for closure of oroantral fistula that could be created because of the displaced root or the attempt by the dental surgeon to retrieve it.
