Abstract

Oroantral communication (OAC) is a common complication following extraction of maxillary posterior teeth because of the close anatomic proximity of the roots to the maxillary sinus. The most frequent methods described in the literature to close an oroantral communication involve buccal or palatal rotational advancement flap surgery or use of the buccal fat pad. These surgical procedures require advanced surgical skill and are associated with donor sit morbidity, such as avascular flap necrosis that can lead to soft tissue graft failure to close the OAC, infection and extreme postoperative patient discomfort that affects patient quality of life. This paper describes a novel technique using leucocyte platelet-rich fibrin matrix obtained from the patient’s own venous blood that leads to predictable soft tissue regeneration and closure of the OAC. This regenerative medicine procedure is clinician friendly, less traumatic compared to traditional methods of OAC closure with minimal postoperative recovery for the patient. 

Highlights

Oroantral communication (OAC) is an iatrogenic complication of the hard and soft tissues of the maxilla due to extraction of the maxillary posterior teeth [1,2,3,4]
The purpose of this publication is to describe a novel technique using regenerative medicine to close an oroantral communication with a leucocyte plateletrich fibrin matrix clot obtained from autologous platelet concentrate of the patient
All the growth factors and stem cells contained within the leucocyte platelet-rich fibrin (L-PRF) matrix have been shown to stimulate soft and hard tissue wound healing [16,17,18,19,20,21,22]

Summary

Introduction

Oroantral communication (OAC) is an iatrogenic complication of the hard and soft tissues of the maxilla due to extraction of the maxillary posterior teeth (premolars and molars) [1,2,3,4]. The purpose of this publication is to describe a novel technique using regenerative medicine to close an oroantral communication with a leucocyte plateletrich fibrin matrix clot obtained from autologous platelet concentrate of the patient. All the growth factors and stem cells contained within the L-PRF matrix have been shown to stimulate soft and hard tissue wound healing [16,17,18,19,20,21,22]. The second L-PRF matrix clot is placed directly over the extraction site (Figure 2b). At 4 weeks post-closure of the OAC, what is consistently observed is complete closure of the OAC due to regeneration of the gingival soft tissues (Figure 3d)
