New technique for closure of an oroantral fistula using platelet-rich fibrin

An oroantral fistula forms when the blood clot comes out of an extraction socket after there has been a breach of the floor and the epithelial membrane of the maxillary sinus. The blood clot would have otherwise served as a "scaffold" for the epithelial cells to grow from the margins towards the centre of the wound to heal it.
