Management of Oroantral Fistulae and Communications: Our Recommendations for Routine Practice

Table 1

Recommendations for the choice of surgical techniques according to the clinical situation.

Clinical situation			Surgical technique
Suspicion of OAC postextraction			Collagen sponges + sutures
Confirmed OAC	Unplanned implant	<10 mm of diameter	Rehrmann’s flap or conservative nonsurgical technique
		10-15 mm of diameter or failure of anterior treatment	Buccal fat pad
		>15 mm of diameter or failure of anterior treatment	Combination of techniques: double or triple thickness closure technique: (i) Buccal fat pad + Rehrmann’s flap; (ii) Buccal fat pad + allogenic membrane + Rehrmann’s flap
	Planned implant	Autogenic or xenogenic bone graft

The implant placements described in the table are for the exact areas of the OACs without considering the probably healthy adjacent areas.
