Oroantral communication repair using bone substitute and platelets rich fibrin

Abstract

Purpose: The aim of this study is to evaluate oroantral communication (OAC) repair using one bone substitute (Fisiograft) and platelets rich fibrin (PRF). Patients and methods: In the present study, eight patients complaining from OAC following extraction of maxillary posterior tooth were selected. The bony defect of the OAC was grafted with Fisiograft sandwiched between two PRF membranes. Then the graft was covered by buccal advancement flap. The patients were followed up clinically after 1, 2, 4 and 12 weeks postoperatively. Radiographic evaluation was performed immediately and after twelve weeks postoperatively. Results: Successful closure of the OAC was achieved in all cases. None of the cases reported recurrence of the OAC or regurgitation of fluids from the nose. There were no signs of dehiscence, infection, allergic reaction, ulceration, or exposure of the material. The covering mucosa returned to the normal color and texture by the end of the first month. Radiographically, the bony defect appeared radiolucent immediate postoperatively. After three months, there was almost complete healing of the bony defect of the OAC. Densitometric measurements showed statistically significant increase in the bone density at the defect area after three months postoperatively. Linear measurements showed no statistically significant vertical loss of alveolar bone after three months postoperatively.

Oroantral fistula after a zygomaticomaxillary complex fracture

“…ElShourbagy et al [11] achieved successful closure of an OAC using Fisiograft bone filler. The combined use of sponge-form Fisiograft together with a platelet-rich fibrin membrane was found to be a simple, easy, and effective technique for OAC closure.…”

Fibrina rica em plaquetas (PRF) como alternativa terapêutica no fechamento de comunicação bucossinusal: relato de caso / Platelet-rich fibrine (PRF) as a therapeutic alternative in closing buccal sinus communication: case report

“…A CBS deve ser fechada para impedir a passagem de fluídos, outros conteúdos da boca e bactérias orais no seio maxilar. O tratamento precoce da CBS é de grande importância para impedir a formação de uma fístula oroantral, além do desenvolvimento de uma sinusite maxilar crônica (ELSHOURBAGY, et al, 2015).…”

Methodological variations affect the release of VEGF in vitro and fibrinolysis’ time from platelet concentrates

“…Currently, platelet concentrates have been the focus of many basic and clinical studies, [10], with the majority of scientific articles mainly addressing its therapeutic potential as a surgical adjuvant in dentistry, such as peri-implantology and maxillofacial surgery [11][12][13][14]. Besides, further studies on the treatment of chronic wounds and muscle-tendinous lesions in humans have introduced the topic in the medical field as a promising therapeutic potential [15][16][17][18][19][20][21].…”
