Comparison of the Clinical Outcomes of Buccal Advancement Flap Versus Platelet-Rich Fibrin Application for the Immediate Closure of Acute Oroantral Communications.

ABSTRACT

The aim of this study was to compare the clinical outcomes of buccal advancement flap surgery to platelet-rich fibrin (PRF) application for the closure of acute oroantral communications (AOACs). In 36 patients, following the extractions of posterior maxillary teeth, AOACs which were larger than 3 mm diameter were detected. In group A, PRF clots were used in 21 patients and group B, classic buccal advancement flap was used in 15 patients. Baseline variables such as pain, the analgesic doses are taken, and swelling was assessed preoperatively. These were also examined on postoperative days 1, 2, 3, and 7, and patients were seen again in the 3rd week. In group A, statistically significant reduction was examined (P < 0.05) in pain and the analgesic doses are taken (sum of 1st, 2nd, 3rd, and 7th days on days 1 and 2) (PRF). The swelling was also significantly less in group A (P < 0.05). The mean duration did not differ between the groups (P > 0.05). In conclusion, both methods were successful for the immediate closure of AOACs. However, a lesser amount of pain and no swelling observed with the use of PRF clots for the immediate closure of AOACs compared to buccal advancement flap surgery.
