Combined surgical management of oroantral communication and buccal bone plate reconstruction using leukocyte and platelet-rich fibrin

Abstract

Introduction: The oroantral communication is a communication between the oral cavity and the maxillary sinus, which has different etiologies, being the most common the extraction of upper posterior teeth, due to the proximity of their root apexes to the floor of the maxillary sinus. Diagnosis is obtained from a combination of anamnesis, physical examination and imaging exams, which may be through radiographs or tomography. There are several approaches to treatment, including the use of Leukocyte and Platelet-Rich-Fibrin membranes for local obstruction of communication. The aim of this work is to report and discuss the use of a Leukocyte and Platelet-Rich-Fibrin membrane for the management of oroantral communication associated with the reconstruction of the buccal bone plate with Stick Bone. Case report: A 61-year-old woman reported discomfort in the region of right maxillary first molar and a history of extraction of the same for about 8 months. The intraoral evaluation revealed the presence of a hyperemic area in the alveolus of the extraction region, and the tomographic examination revealed an oroantral communication associated with loss of local vestibular bone plate. Final considerations: Therefore, the use of these membranes are suitable for obstructing these communications, being a propper plug due to its adhesive properties in the perforation area, not being associated to any immunological reaction, easy and fast preparation, highly biocompatible, low cost, prevention of the depth of the vestibular sulcus and do not present any risk of infection.
