Oroantral fistula: broad-contact closure

1. A modified Rehrmann's buccal advancement flap technique is described for the treatment of medium-sized oroantral fistulae. 2. Its advantages are listed. 3. Disadvantages are: a slightly longer operating time, and because of the longer movement of the buccal flap the buccal sulcus temporarily is shallower than the traditional buccal flap technique. 4. The buccal sulcus however, is reconstituted after a period of two months.
