There often occurs an antro-oral fistula after extraction of the upper molar tooth. When the maxillary sinus is normal, nearly all of the extraction wounds will heal by a routine post-exodontic treatment. However, when the maxillary sinus is infected unfortunately systemic and local chemotherapy with antibiotics should be instituted immediately and it is convenient to use a partial denture devised by the authors in the extraction wound. The treatment of the fistula formed in case of removing the tooth causing the maxillary sinusitis is acute or chronic. If it is of the chronic type of several months or more, the fistula will not close unless a radical operation is performed.
When the patient already has a chronic sinusitis it is idealistic to perform the radical operation for sinusitis and the operation for closure of the fistula simultaneously.
If can be considered from the authors' experience that an antro-oral fistula occurs in the order of first molar, second molar and second bicuspid.
