title: Antral retriever and displaced dental implants in the maxillary sinus.
abstract: OBJECTIVE
  Removal of antral foreign bodies after implantation is mandatory to avoid infectious processes and may be a troublesome question. Different surgical approaches could be considered, with several limitations and morbidities.
  
  
  METHODS
  We present a new tool (Antral Retriever) conceived to remove antral dental implants or any other migrated material through a minimally invasive canine fossa approach, under continuous endoscopic view and local anesthesia.
  
  
  CONCLUSIONS
  Antral Retriever enables the surgeon to successfully remove antral foreign bodies through a canine fossa approach under continuous endoscopic visualization and local anesthesia, with minimal discomfort for the patient
