Oroantral communication (OAC) is one of the main complications of extracting antral or sinus teeth. OAC is a gap between the maxillary sinus and the oral cavity. When left untreated, it causes maxillary sinusitis and dramatically impairs the patient’s quality of life. Numerous surgical treatment techniques have been described, from mucosal techniques to using bone substitutes or very conservative alternative means. Many cases of recurrence after treatment have been reported, and the choice of the method adapted to the clinical situation remains challenging. Therefore, it is necessary to establish a correct diagnosis and choose the surgical technique best adapted to the case. This work is aimed at reviewing several techniques for the treatment of OAC and at describing our recommendations for use in daily practice for each of them through four clinical cases.
